A square has an area of 81 square inches. How long are its sides?
Someone please I need help ASAP !!
Answer:
Step-by-step explanation:
it is like 9x9=81
but yeah like he said it is a square so all sides are the same
but that is if you want to find the parameter
this question is talking about area
so when a question gives you an area you ask yourself what can be multiplied by what in order to give me the area
or since all sides are the same like he said you could just do simple division and do 81/9 which will =9
and since the question mentions that the area is in square inches it is obvious that the answer would be put in inches
answer: 9 inches
Anna had three times as many as joe bead.they had 480 beads together. Mr taylor have an equal to each of them. Zoe then had half the number of beads that Anna had. How many beads did mr taylor give them.
Mr. Taylor gave them 1500 beads each.
What is expression?In mathematics, an expression is a combination of numbers, variables, and operators that are written in a specific order and can be evaluated to produce a value. Expressions can be simple or complex, and they can involve basic arithmetic operations like addition, subtraction, multiplication, and division, as well as more complex operations like exponents, logarithms, and trigonometric functions.
Let's start by setting up equations to represent the information given in the problem:
Let's assume that Joe has x beads.
Then, Anna has 3x beads.
Together, Joe and Anna have x + 3x = 4x beads.
We know that the total number of beads they have is 480, so:
4x = 480
Solving for x, we get
x = 120
So, Joe has 120 beads, and Anna has 3x = 3(120) = 360 beads.
Mr. Taylor gave each of them an equal number of beads, which means he gave them each (480 + Mr. Taylor's beads) / 3 beads.
Zoe had half as many beads as Anna, so she had 360 / 2 = 180 beads.
We can now set up an equation to find how many beads Mr. Taylor gave them
(480 + Mr. Taylor's beads) / 3 = 120 + 360 + 180
Simplifying and solving for Mr. Taylor's beads, we get:
480 + Mr. Taylor's beads = 3(660)
480 + Mr. Taylor's beads = 198
Mr. Taylor's beads = 1980 - 480
Mr. Taylor's beads = 1500
Therefore, Mr. Taylor gave them 1500 beads each.

Use integers to represent the values in the statement.
The highest elevation in a country is a mountain, with an altitude of 14,240 feet. The lowest elevation in the country is a valley, with an altitude of 285 feet below sea level.
The integer represents the mountain's altitude, measured in feet.
Answer:
Highest Elevation: 14240
Lowest Elevation: -285
Step-by-step explanation:
Given
\(Highest\ Elevation = 14,240\ ft\) above sea level
\(Lowest\ Elevation = 285\ ft\) below sea level
Required
Represent both altitudes as an integer
For the Mountain:
Take the sea level as 0 feet
\(Altitude = Highest\ Elevation - Sea\ Level\)
\(Altitude = 14240 - 0\)
\(Altitude = 14240\)
Hence, the integer is 14240
For the Valley:
Take the sea level as 0 feet
\(Altitude = Sea\ Level - Lowest\ Elevation\)
\(Altitude = 0 - 285\)
\(Altitude = -285\)
Hence, the integer is -285

4. RSTU is a trapezoid because the opposite sides RS and UT are parallel.
5. RSTU is not an isosceles trapezoid because the diagonals are not congruent.
How to verify that RSTU is a trapezoid?In order to verify that RSTU is a trapezoid, we would have to determine slope of the pair of opposite sides and check whether at least one pair of opposite sides are parallel;
RU ║ ST
Slope of side RU = Slope of side ST
Slope of RU = (y₂ - y₁)/(x₂ - x₁)
Slope of RU = (1 + 3)/(5 + 3)
Slope of RU = 4/8
Slope of RU = 0.5.
Slope of RS = (y₂ - y₁)/(x₂ - x₁)
Slope of RS = (-9 + 3)/(-4 + 3)
Slope of RS = -6/-1
Slope of RS = 6.
Slope of ST = (y₂ - y₁)/(x₂ - x₁)
Slope of ST = (-2 - 1)/(10 - 5)
Slope of ST = -3/5
Slope of ST = -0.6.
Slope of UT = (y₂ - y₁)/(x₂ - x₁)
Slope of UT = (-2 + 9)/(10 + 4)
Slope of UT = 7/14
Slope of UT = 0.5.
Therefore, RSTU is a trapezoid because the opposite sides RS and UT are parallel.
Question 5.
In order to determine whether RSTU is an isosceles trapezoid, we would have to determine length of the diagonals by using the distance formula and check whether they are congruent;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance RT = √[(-2 + 3)² + (10 + 3)²]
Distance RT = √170 units.
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance US = √[(5 + 4)² + (1 + 9)²]
Distance US = √181 units.
Therefore, RSTU is not an isosceles trapezoid because the diagonals RT and US are not congruent.

Every student of a school donated as much money as their number to make a fund for Corona- virus victims. If they collected Rs.13225 altogether, how many students donated money in the fund?
Answer:
The problem statement suggests that the series of donations is arithmetic, as each student's donation increases by one as their number increases. Therefore, we can apply the formula for the sum of an arithmetic series to solve this problem.
In an arithmetic series, the sum S of n terms is given by:
S = n/2 * (a + l)
where:
- n is the number of terms (which represents the number of students in this case),
- a is the first term (in this case, the first student's number, which would be 1), and
- l is the last term (in this case, the last student's number, which we don't know yet).
Given that S = Rs. 13225, we have:
13225 = n/2 * (1 + l)
Since this is an arithmetic series starting from 1, the last term, l, is equal to n. Thus, we can substitute l with n:
13225 = n/2 * (1 + n)
Multiplying through by 2 to clear the fraction gives:
26450 = n * (1 + n)
Rearranging to a quadratic equation gives:
n^2 + n - 26450 = 0
This is a quadratic equation in the form of ax^2 + bx + c = 0. To solve for n, we can use the quadratic formula, n = [-b ± sqrt(b^2 - 4ac)] / (2a). But since n cannot be negative in this context (as it represents the number of students), we will only consider the positive root.
Applying the quadratic formula, we find that the positive root is approximately 162.5. However, the number of students must be a whole number. Therefore, the number of students is 163, because the 163rd student did not donate fully as per their number, and that's why the total amount doesn't reach the full sum for 163 students.
So, there were 163 students who donated money to the fund.
What is the domain restriction that will allow you to find an inverse of the function f(x) = 3(x − 9)2 + 4?
Answer:
f(x) = 3(x − 9)^2 + 4
To find the inverse of f(x), first we denote: y = 3(x - 9)^2 + 4, we then find a way to express x in term of y.
y = 3(x - 9)^2 + 4
<=> y - 4 = 3(x - 9)^2
<=> (y - 4)/3 = (x - 9)^2
<=> sqrt[(y - 4)/3] = x - 9
<=> x = sqrt[(y - 4)/3] + 9
Denote left side is g(x), and variable y on the right side is x, we have:
g(x) = sqrt[(x - 4)/3] + 9
g(x) is inverse of f(x)
Here, (x - 4)/3 must be not a negative number (because of the definition of square root (sqrt) of a real number)
=> x - 4 >= 0 or x >= 4
=> The restriction domain of g(x), which is the inverse of f(x) is x >= 4

Answer to the given famous joke is: "The plant in math class forgot to square its roots."
This joke plays on the mathematical concept of "squaring roots" and humorously applies it to a plant in a math class context. In mathematics, "squaring" a number means multiplying it by itself, and the "square root" of a number is the value that, when multiplied by itself, gives the original number.
In this joke, the plant is personified, as if it were a student in a math class, and humorously forgets to square its roots, which is something entirely unrelated to plants but fits within the mathematical context. The humor comes from the unexpected and clever blending of a mathematical concept with a non-mathematical subject, resulting in a lighthearted and punny punchline.

-3[(w-6)^2+x]^2 ; w=5, x=6
The solution to the above question is -147
-3[(w-6) ^2+x] ^2 where the value of w = 5 and x amounts to 6
Using algebraic identity: (a-b) ^2 = (a^2 -2ab+b^2)
= -3 [(w^2 -2w*6 +6^2) + x] ^2
= -3 [(w^2 -12w+36) + x] ^2
now substitute the value of w = 5
= -3 [(5^2 -12*5+36) + x] ^2
= -3 [(25 -60+36) + x] ^2
= -3 [1+ x] ^2
Using algebraic identity: (a+ b) ^2 = a^2 +2ab + b^2
= -3 [1^2+2x*1+ x^2]
= -3 [1+2x+ x^2]
now substitute the value of x = 6
= -3 [1+2*6+ 6^2]
= -3 [1+12+ 36]
= -3 [49]
= -147
The above answer can be derived through direct substitution also. Both the methods will any way give the same answer.

Annie is running a trail that is 4 1/2 miles long. She ran the first 2/3 of the distance. Then the trail became very steep, so she slowed down to a walk. Annie walked for 1/2 of the remaining distance and then ran again for the rest of the way. How far did Annie walk? Write the answer as a simplified fraction.
Answer:
\(\frac{3}{4}\) miles
Step-by-step explanation:
Total length of the trail = \(4\frac{1}{2}\) miles = \(\frac{9}{2}\) miles
She ran the first \(\frac{2}{3}\) of the distance i.e.
The distance for which she ran = \(\frac{2}{3} \times \frac{9}{2} = 3\ miles\)
Remaining distance = Total length of trail minus the distance for which she has already run = \(\frac{9}{2} - 3 = \frac{3}{2}\) miles
Given that: After running, Annie has to walk due to steep nature of the trail, So, Annie walked for \(\frac{1}{2}\) of the remaining distance.
The distance for which Annie walked = \(\frac{1}{2} \times\) Remaining distance
The distance for which Annie walked = \(\frac{1}{2} \times\) \(\frac{3}{2}\) = \(\frac{3}{4}\) miles
So, the answer is: \(\frac{3}{4}\) miles

what type of scale is used on the map?
The type of scale commonly used on maps is a graphic scale, which uses a line or bar to represent distances accurately.
The type of scale used on a map is known as a map scale. It is a graphical representation that shows the relationship between distances on the map and their corresponding measurements in the real world. A map scale allows us to understand the size and proportion of features depicted on the map.
There are three main types of map scales: verbal scales, graphic scales, and representative fraction scales.
Verbal Scale: A verbal scale uses words to describe the relationship between distances on the map and real-world measurements. For example, a verbal scale might state "1 inch represents 1 mile" or "1 centimeter represents 10 kilometers." Verbal scales are commonly used on small-scale maps, where the level of detail is not as important.
Graphic Scale: A graphic scale, also known as a bar scale or linear scale, uses a line or a bar marked with specific distances. This line is divided into equal segments that represent units of measurement. By comparing the length of the line on the map to the corresponding distance in the real world, you can determine distances accurately. Graphic scales are often found on the margin or the legend of a map and are commonly used on medium- to large-scale maps.
Representative Fraction (RF) Scale: A representative fraction scale expresses the relationship between map distances and real-world distances using a ratio. For example, a representative fraction of 1:100,000 means that one unit of measurement on the map represents 100,000 of the same units in the real world. This type of scale is useful because it allows for precise calculations and conversions between map distances and real-world distances. Representative fraction scales are commonly used on topographic maps and engineering plans.
It's important to note that a map may include multiple scales to accommodate different levels of detail. For instance, a large-scale map of a city may have a more detailed scale than a small-scale map of an entire country.

A bucket contains six white balls and five red balls. A sample of four balls is selected
at random from the bucket, without replacement. What is the probability that the
sample contains...
Exactly two white balls and two red balls?
At least two white balls?
To solve this problem, we can use the formula for probability:
P(event) = number of favorable outcomes / total number of outcomes
First, let's find the total number of outcomes. We are selecting 4 balls from 11 without replacement, so the total number of outcomes is:
11C4 = (11!)/(4!(11-4)!) = 330
where nCr is the number of combinations of n things taken r at a time.
Now let's find the number of favorable outcomes for each part of the problem.
Part 1: Exactly two white balls and two red balls
To find the number of favorable outcomes for this part, we need to select 2 white balls out of 6 and 2 red balls out of 5. The number of ways to do this is:
6C2 * 5C2 = (6!)/(2!(6-2)!) * (5!)/(2!(5-2)!) = 15 * 10 = 150
So the probability of selecting exactly two white balls and two red balls is:
P(2W2R) = 150/330 = 0.45 (rounded to two decimal places)
Part 2: At least two white balls
To find the number of favorable outcomes for this part, we need to consider two cases: selecting 2 white balls and 2 red balls, or selecting 3 white balls and 1 red ball.
The number of ways to select 2 white balls and 2 red balls is the same as the number of favorable outcomes for Part 1, which is 150.
To find the number of ways to select 3 white balls and 1 red ball, we need to select 3 white balls out of 6 and 1 red ball out of 5. The number of ways to do this is:
6C3 * 5C1 = (6!)/(3!(6-3)!) * (5!)/(1!(5-1)!) = 20 * 5 = 100
So the total number of favorable outcomes for selecting at least two white balls is:
150 + 100 = 250
And the probability of selecting at least two white balls is:
P(at least 2W) = 250/330 = 0.76 (rounded to two decimal places)

A new cylindrical can with a diameter of 4cm is being designed by a local company. The surface area of the can is 140 square centimeters. What is the height of the can? Estimate using 3.14 for pi and round to the nearest hundredth. Apply the formula for the surface area of a cylinder SA=2B+Ph
The height of the can of cylinder shape is 9.14 cm.
What is a cylinder?
In mathematics, a cylinder is a three-dimensional solid that maintains two parallel bases separated by a curved surface at a specific distance. These bases frequently have a circular shape (like a circle), and an axis connects their respective centres.
We are given the diameter as 4 cm.
So, the radius is 2cm.
Also, it is given that the surface area of the can is 140 square centimeters.
So, using the surface area of cylinder, we get
⇒Area = 2πr (h + r)
⇒140 = 2π * 2 (h + 2)
⇒140 = 4π (h + 2)
