Answer:
Rounded to the Nearest Tenth is V=769.3π
Step-by-step explanation:
The diameter of the figure is 7, so the radius is 3.5. So, the radius is 3.5
The height is 20
Formula for cylinders= V= Bh or V=πr2h
I will use V=πr2h
V=π(3.5)²(20)
V=π(12.25)(20)
V=π(245)
V=769.3π

Answers
Answer:
The answer is 4.
Step-by-step explanation:
This is a basic one-step algebra problem.
We have: 3x = 12.
We would like find what x equals. In order to do that, we must have the x variable on one side of the equals sign, and the rest of the numbers on the other side. In other words, we have to isolate the x variable away from its coefficient.
To do this, we must divide BOTH sides of the equation by 3. This would mean that the 3 on the left side of the equals sign cancels out, totally getting rid of the 3.
Here's what it should look like: \(\frac{3x}{3} = \frac{12}{3}\)
Now, we actually divide both sides now, which should look like this: \(x = 4\)
This is because 3 divided by 3 is 1, and 12 divided by 3 is 4.
Hence, our solution for x is 4. Hope this helped!

Step-by-step explanation: I know thins because I did eduenuty
Answer:
B. 36 questions
Step-by-step explanation:
First, change the fraction to a percentage. Now you need to find 80% of 45. I use this setup here:
80/100 = x/45
To find x, or the number of questions you got correct, you will multiply 45 and 80.
45 x 80 = 3,600
You will then divide the product by the remaining number, which is 100.
3,600/100 = 36
x (questions you correctly answered) = 36
Other Way to Solve:
If that way of solving is too complicated, you can always do this:
8/10 x 45/1
8 x 45 = 360
10 x 1 = 10
360/10 = 36

Step-by-step explanation:
the exponent will tell you how many places u need to move the decimal. 5.7 × 10 to the 2nd power = 570. u moved the decimal 2 places to the right.
If we interpret the statement correctly "5.7 x 5,700,000,000,000" means to multiply 5.7 with 5,700,000,000,000, which gives us the result of 32,490,000,000,000.
Therefore, we can write the statement as: 5.7 x 5,700,000,000,000 = 32,490,000,000,000.

Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given that Jacinta says that the product of a rational number and an irrational number is always irrational.
Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.

Answers
Answer:
Step-by-step explanation:
a deli wraps its cylindrical containers of hot food items with plastic wrap. the minimum amount of plastic wrap needed to completely wrap 8 containers is: 785.4 square inches.
What is the minimum amount of plastic wrap needed?
The area of each circular end is:
A = πr^2
where r is the radius of the end. The diameter of each container is given as 5.5 inches, so the radius is half of that, or 2.75 inches. Using π = 3.14, we get:
A = 3.14 * (2.75in)^2
A = 23.68in^2 (rounded to two decimal places)
The area of the rectangular side is:
A = h * circumference
where h is the height of the container and circumference is the distance around the circular end. The circumference is equal to the diameter times π, so we have:
circumference = 5.5in * π
circumference = 17.27in (rounded to two decimal places)
Using the given height of 3 inches, we get:
A = 3in * 17.27in
A = 51.81in^2 (rounded to two decimal places)
Therefore, the total surface area of each container is:
A = 2 * 23.68in^2 + 51.81in^2
A = 98.17in^2 (rounded to two decimal places)
To wrap 8 containers, we need to multiply the surface area of each container by 8:
total surface area = 8 * 98.17in^2
total surface area = 785.36in^2 (rounded to two decimal places)
Therefore, we need a minimum of 785.36 square inches of plastic wrap to completely wrap 8 cylindrical containers of hot food items. Rounding to the nearest tenth, the answer is 785.4 square inches.

If a widget factory as a fixed operating cost of $2,500 per day plus a cost of $1.50 per widget produced. If a widget sells fro $5.00, what is the least number of widgets that must be sold per day to make a profit?
Answers
Answer:
At least 714 numbers of widgets must be sold per day to make a profit.
Given fixed operating cost = $2,500 per day cost of widget =$ 1.50
widget sells =$ 5.00
Cost function = C(X)=1.50x+2500
Revenue function = R(X)=5 x
At Break Even point R (X) = C (X)5
X= 1.50X+2003.5
X =2500X =714
Hence to reach break even point or make profit 714 no to be sold. R(714)= 3571.

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Given line AB, use similar triangles to prove that the slope of line AB is the same between any two points on the line.
1. Create two similar, but not equal, right triangles using segments of line AB as the hypotenuse of each triangle. For the first right triangle use point A(-5,-1) and choose another point on the line to form the hypotenuse. For the second right triangle use point B(4,3.5) and choose another point on the line to form the hypotenuse. For each point used to create the triangles, name the point with a capital letter and coordinates. For example, the triangle using point A could be named ΔACE and the triangle using point B could be named ΔBDF.
2. For the pair of similar triangles created in Part 1, list three pairs of corresponding angles that are equal and three sets of proportionate sides.
3. Use the pair of similar triangles created in Part 1 to demonstrate that the slope of line is the same between any two points on the line.
