Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 30 feet and a height of 16 feet. Container B has a diameter of 22 feet and a height of 20 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full. To the nearest tenth, what is the percent of Container A that is full after the pumping is complete?
Answers
Answer:
32.8%
Step-by-step explanation:
Container A:
Diameter = 30 feet
Radius = diameter/2 = 30/2
= 15 feet
Height = 16 feet
Volume of a cylinder = πr²h
= 3.14 * 15² * 16
= 3.14 * 225 * 16
= 11,304 feet ³
Container B:
Diameter = 22 feet
Radius = diameter / 2
= 22/2 = 11 feet
Height = 20 feet
Volume of a cylinder = πr²h
= 3.14 * 11² * 20
= 3.14 * 121 * 20
= 7598.8 feet ³
what is the percent of Container A that is full after the pumping is complete?
Container A - container B
= 11,304 feet ³ - 7598.8 feet ³
= 3,705.2 feet ³
percent of Container A that is full after the pumping is complete = 3,705.2/11,304 × 100
= 0.328 × 100
= 32.8%
percent of Container A that is full after the pumping is complete = 32.8%

A farmer planted corn in a square field. One side of the field measures 39 yards. What is the area of the cornfield?
Answers
Answer:
The area of the cornfield is 1,529 yards.
Step-by-step explanation:
In this case, since the statement indicates that it is a square field, you have to use the formula to calculate the area of a square, which is:
A=a², where:
A is the area
a is the lenght of side
The statement says that one side measures 39 yards, so this would be a, and you can replace this value on the formula:
A=39²
A=1,521
According to this, the answer is that the area of the cornfield is 1,529 yards.

Brian needs to find the value of a number, a, so that when (x^2+3x) is added to the binomial (3x^2+ax), the sum simplifies to 4x^2+12x. What is the value of a?
Answers
Answer:
a = 9
Step-by-step explanation:
First we need to add (x^2+3x) to (3x^2+ax),
(x^2+3x)+(3x^2+ax)
Expand
= x^2+3x+3x^2+ax
Collect the like terms
= x^2+3x^2+3x+ax
= 4x^2 + 3x + ax
= 4x^2+(3+a)x
Equate the solution to 4x^2+12x
4x^2+(3+a)x = 4x^2+12x
Comparing the like terms on both sides
(3+a)x =12x
3 + a = 12
a = 12 - 3
a = 9
Hence the value of a is 9

the difference of the mean in the case of mean absolute deviation is 2.5
Step-by-step explanation:
The computation of the difference of the mean is shown below:
Difference is of
= B - A

How does the graph of f(x) = 3|x+2|+4 relate to its parent function?
A. The parent function has been translated to the left.
B. The parent function has been stretched.
C. The parent function has been compressed.
D. The parent function has been translated up.
Answers
Answer:
If the parent function is f(x)=|x+2|+4 and it is moved to the left 2 units vertically stretched by a factor of 3 and moved up by 4 units in that order because to move a function to left c units, add c to every x to vertically stretch function by a factor of c, multiply the whole function by c to move function up c units, add c to the whole function so it is 2 to the left, vertically stretched by a factor of 3 then moved up 4 units.

The parent function was translated upward. The parent function was moved to the left. The parent function has been overburdened. What is a parent function?In mathematics, a parent function is the simplest function in a family of functions that maintains the definition of the entire family.
In graphing, the parent function is the basic equation where the graph is not transformed. A straight line, for example, has a parent function of y=x. The equations from such transformations will still be part of the family of lines if this graph is translated, reflected, rotated, or dilated.

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.410.410, point, 4 years; the standard deviation is 1.91.91, point, 9 years.
Use the empirical rule (68-95-99.7\%)(68−95−99.7%)left parenthesis, 68, minus, 95, minus, 99, point, 7, percent, right parenthesis to estimate the probability of a meerkat living less than 16.116.116, point, 1 years.
Answers
Answer:
99.85%
Step-by-step explanation:
The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4 years; the standard deviation is 1.9 years.
Use the empirical rule (68-95-99.7%) to estimate the probability of a meerkat living less than 16.1 years.
Solution:
The empirical rule states that for a normal distribution most of the data fall within three standard deviations (σ) of the mean (µ). That is 68% of the data falls within the first standard deviation (µ ± σ), 95% falls within the first two standard deviations (µ ± 2σ), and 99.7% falls within the first three standard deviations (µ ± 3σ).
Therefore:
68% falls within (10.4 ± 1.9). 68% falls within 8.5 years to 12.3 years
95% falls within (10.4 ± 2*1.9). 95% falls within 6.6 years to 14.2 years
99.7% falls within (10.4 ± 3*1.9). 68% falls within 4.7 years to 16.1 years
Probability of a meerkat living less than 16.1 years = 100% - (100% - 99.7%)/2 = 100% - 0.15% = 99.85%

Fran withdrew 6.4% of her savings account to put towards the purchase of a new car. If she put $2,400 down on her car, what was her savings account balance before she withdrew the money?
Answers
Answer:
$3,550 dollars
Step-by-step explanation:
6.4% off savings
- a total of $2,400
The percentage is that indicating the hundredth total amount in the saving account before withdrawing such that 6.4% of that is $2400 is $37500.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Let's suppose the total amount of money before withdrawing x.
It is known that x% of y is given as, (x/100)y.
Therefore,6.4% of x is (6.4/100)x = 0.064x
The 6.4% of the x is 2400
So, 0.064x = 2400
x = 2400/0.064 = $37500
Hence "The percentage is that indicating the hundredth total amount in the saving account before withdrawing such that 6.4% of that is $2400 is $37500.".
