The larger of two numbers is 6 more than 3 times the smaller. If the twice the larger number is increased by 3 times the smaller, the result is 3. Find the numbers by solving algebraically. Show your work including the equations.
Answer:
The smaller number = -1
The larger number = 3
Step-by-step explanation:
Let the smaller number = a
Let the larger number = b
The larger of two numbers is 6 more than 3 times the smaller.
b = 3a + 6........... Equation 1
If the twice the larger number is increased by 3 times the smaller, the result is 3.
2b + 3a = 3........ Equation 2
Hence:
We Substitute 3a + 6 for b in Equation 2
2b + 3a = 3
2(3a + 6) + 3a = 3
6a + 12 + 3a = 3
9a = 3 - 12
9a = -9
a = -9/9
a = -1
b = 3a + 6........... Equation 1
b = 3(-1) + 6
b = -3+ 6
b = 3
Therefore,
The smaller number = -1
The larger number = 3

Two cylinders, a and b, each started with different amounts of water. The graph shows how the height of the water changed as the volume of water increased in each cylinder. Match the graphs of a and b to Cylinders P and Q. Explain your reasoning. height in centimeters b volume in milliliters P
To match the graphs of cylinders a and b to cylinders P and Q, we need to analyze the relationship between the height of the water and the volume of water in each cylinder.
Cylinder P would correspond to graph b, while Cylinder Q would correspond to graph a.
The reasoning behind this is as follows:
Cylinder P, corresponding to graph b, shows a steeper increase in height with increasing volume. This indicates that the water level rises quickly as more volume is added, suggesting that the cylinder has a smaller cross-sectional area. Since height is directly proportional to volume for a cylinder, a smaller cross-sectional area would result in a higher rise in height for the same volume of water.
Cylinder Q, corresponding to graph a, shows a slower increase in height with increasing volume. This implies that the water level rises more gradually as more volume is added, indicating a larger cross-sectional area. A larger cross-sectional area would result in a smaller increase in height for the same volume of water.
In summary, the steeper graph b matches Cylinder P with a smaller cross-sectional area, while the gentler graph a matches Cylinder Q with a larger cross-sectional area.

A marketing firm tracks data on grocery store visits. In one study, it finds that
the probability that a shopper buys bread during a visit to the grocery store is
0.60, and the probability that a shopper buys cheese is 0.20
Event A = A shopper buys bread.
Event B = A shopper buys cheese.
A and B are independent events if
-
A. the probability of buying bread or cheese is 0.12
B. the probability of buying bread and cheese is 0.12
C. the probability of buying bread or cheese is 0.80
D. the probability of buying bread and cheese is 0
Answer:
B.the probability of buying bread and cheese is 0.12
Step-by-step explanation:
The probability of buying bread and cheese is 0.12.
The correct answer is option B.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To determine if events A and B are independent,
We need to check if the occurrence of one event affects the probability of the other event.
If the events are independent, the probability of both events occurring can be calculated by multiplying the probabilities of each individual event.
Now,
Let A be the event that a shopper buys bread, and B be the event that a shopper buys cheese.
Then, we know that:
P(A) = 0.60 (the probability of buying bread)
P(B) = 0.20 (the probability of buying cheese)
If A and B are independent events, then the probability of both events occurring (i.e., the shopper buys both bread and cheese) is given by:
P(A and B) = P(A) x P(B)
Substituting the given values.
P(A and B)
= 0.60 x 0.20
= 0.12
This means that the probability of a shopper buying both bread and cheese is 0.12 if events A and B are independent.
Therefore,
The probability of buying bread and cheese is 0.12.

the graph of a certain quadratic function has no x-intercepts. Which of the following are possible values or the disriminant?
The possible values for the discriminant include the following:
A. -1
D. -18
What is the x-intercept?In Mathematics and Geometry, the x-intercept is the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" or y-value is equal to zero (0).
Since the graph of this quadratic function has no x-intercepts, we can logically deduce that the zeros, roots, or x-intercepts of this quadratic function must be an imaginary number.
Discriminant, D = b² - 4ac
In conclusion, we can reasonably infer and logically deduce that negative numbers such as -1 and -18 are possible values for the discriminant.

Complete the explanation of how you can adjust your answer without weighing the liquid again. Then give the weight in kilograms. If necessary, round your answer to the nearest tenth.
only right anwres
Answer:
7.7 pounds = 3.5 kilograms
Step-by-step explanation:
Given that,
Weight of a gallon of liquid = 7.7 pounds
We need to find weight in kilograms.
We must know the relation between pounds and kilograms and it is as follows :
1 kilogram = 2.20 pounds
or
1 pounds = (1/2.2) kilograms
7.7 pounds = (7.7/2.2) kilograms
= 3.5 kilograms
Hence, 7.7 pounds is equal to 3.5 kilograms.

The volume of the solid of revolution formed by revolving the region bounded by f(x) = -3x² + 8 and g(x) = 3x² + 2 about the x-axis is 16π cubic units.
To find the volume of the solid of revolution formed by revolving the region bounded by the curves f(x) = -3x² + 8 and g(x) = 3x² + 2 about the x-axis, we can use the method of cylindrical shells and integrate.
First, let's find the points of intersection between the two curves by setting them equal to each other:
-3x² + 8 = 3x² + 2
Rearranging the equation, we get:
6x² = 6
x² = 1
x = ±1
So, the curves intersect at x = -1 and x = 1.
To calculate the volume, we'll integrate along the x-axis from x = -1 to x = 1. The volume of each cylindrical shell can be determined by multiplying the circumference (2πy) by the height (dx), where y represents the distance from the axis of revolution to the curve at a given x-value.
The radius of the cylindrical shell, y, can be obtained by subtracting the lower curve (f(x)) from the upper curve (g(x)). Therefore, y = (3x² + 2) - (-3x² + 8) = 6x² - 6.
The integral to compute the volume of the solid can be expressed as:
V = ∫[from -1 to 1] 2π(6x² - 6) dx
V = 2π ∫[from -1 to 1] (6x² - 6) dx
Simplifying and evaluating the integral, we get:
V = 2π [2x³ - 6x] [from -1 to 1]
V = 2π [(2(1)³ - 6(1)) - (2(-1)³ - 6(-1))]
V = 2π [2 - 6 - (-2 + 6)]
V = 2π [8]
V = 16π

Find the number of integers between 1 and 1000 that are divisible by 12 or 15, but not by both 12 and 15.
Count the multiples of 12:
⌊1000/12⌋ = 83
(where ⌊x⌋ denotes the "floor" of x, or the largest integer that is less than or equal to x)
These are the integers
{12, 24, 36, 48, …, 996}
Count the multiples of 15:
⌊1000/15⌋ = 66
These are
{15, 30, 45, 60, …, 990}
Count the multiples of both 12 and 15; these are multiples of LCM(12, 15) = 60:
⌊1000/60⌋ = 16
These are
{60, 120, 180, 240, …, 960}
Now use the inclusion/exclusion principle to count the multiples of either 12 or 15, but not both:
83 + 66 - 2•16 = 117
Among the multiples of 12 and the multiples of 15, we count the numbers that are multiples of both 12 and 15. By subtracting the number of multiples of both (16), we get the count of integers that are either divisible by 12 or 15. We subract 16 again to remove those that are divisible by both 12 and 15.
