Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 13 feet and a height of 14 feet. Container B has a radius of 10 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full.
After the pumping is complete, what is the volume of water remaining in Container A, to the nearest tenth of a cubic foot?
Answer:
The percentage ≅ 48.4%
Step-by-step explanation:
The volume of water left in container A = 2197π - 1134π = 1063π feet³
* To find the percentage of the water that is full after pumping
is complete, divide the volume of water left in container A
by the original volume of the container multiplied by 100
∴ The percentage = (1063π/2197π) × 100 = 48.3841 ≅ 48.4%

Step-by-step explanation:
A tire from Karens car is shown below Which is closest to the distance traveled, in feet, after 3 full rotations of the tire? use pi= 22/7
Answer:
264 inches
Step-by-step explanation:
Circumference = pi x diameter
28 x 22/7 = 88 (in)
88 x 3 = 264 (in)
The closest distance traveled by Karen's car is, 18.86 feet.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We know that;
One rotation of the tire is equal to the circumference of the tire.
And, The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where, π = 22/7
d = diameter
Here, The size of one revolution = 2 x 22/7
= 44/7 feet
Hence, The distance covered in one rotation of the tire is 44/7 feet
So, The distance covered in 3 rotations = (44/7) x 3
= 18.86 feet

Answer:
The answer is B
Step-by-step explanation:
You can turn them into improper fractions
so
[tex]10 \frac{1}{2} = \frac{21}{2} [/tex]
[tex]2 \frac{1}{4} = \frac{9}{4} [/tex]
when we divide we invert the second fraction
[tex] \frac{21}{2} \div \frac{9}{4} = \frac{21}{2} \times \frac{4}{9} [/tex]
now we can multiply as usual
[tex] \frac{21}{2} \times \frac{4}{9} = \frac{84}{18} [/tex]
[tex] \frac{84}{18} = \frac{14}{3} = 4 \frac{2}{3} [/tex]

You just found the car of your dreams. It will cost $24,000. You have been saving for a car since 3rd grade and now have $6,000. Your dad will match that with another $6,000 for the car. You will pay a simple interest of 10% on the balance of what you owe after you give the car dealership the money you have between your dad and yourself.
How much money will you still owe?
Answer:
I think the answer is 13,200
Step-by-step explanation:
6k+6k=12,000 half of the price of the car
.10x12000= 10% interest = 1200 + rest of the balance(12,000)=13,200

13.78 - 9.13 - m = 0 (subtracting 9.13 from both sides)
m = 13.78 - 9.13 (adding m to both sides)
m = 4.65
