82 because it is the opposite of -(-82)
Answer:
![\sqrt[3]{3140^2\pi}\approx 146.41\ ft^2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3140%5E2%5Cpi%7D%5Capprox%20146.41%5C%20ft%5E2)
Step-by-step explanation:
The volume of the cylinder is
where r is the base radius and H is the height.
Since 
and V=1570 cubic feet, then
![1570=\pi r^2\cdot \dfrac{r}{2},\\ \\1570=\dfrac{\pi r^3}{2},\\ \\r^3=\dfrac{3140}{\pi},\\ \\r=\sqrt[3]{\dfrac{3140}{\pi}}\ ft.](https://tex.z-dn.net/?f=1570%3D%5Cpi%20r%5E2%5Ccdot%20%5Cdfrac%7Br%7D%7B2%7D%2C%5C%5C%20%5C%5C1570%3D%5Cdfrac%7B%5Cpi%20r%5E3%7D%7B2%7D%2C%5C%5C%20%5C%5Cr%5E3%3D%5Cdfrac%7B3140%7D%7B%5Cpi%7D%2C%5C%5C%20%5C%5Cr%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B3140%7D%7B%5Cpi%7D%7D%5C%20ft.)
The area of its bottom floor is
![A_{floor}=\pi r^2=\pi\cdot \left(\sqrt[3]{\dfrac{3140}{\pi}}\right)^2= \sqrt[3]{3140^2\pi}\approx 146.41\ ft^2.](https://tex.z-dn.net/?f=A_%7Bfloor%7D%3D%5Cpi%20r%5E2%3D%5Cpi%5Ccdot%20%5Cleft%28%5Csqrt%5B3%5D%7B%5Cdfrac%7B3140%7D%7B%5Cpi%7D%7D%5Cright%29%5E2%3D%20%5Csqrt%5B3%5D%7B3140%5E2%5Cpi%7D%5Capprox%20146.41%5C%20ft%5E2.)
Answer:
You just divide 6 by 3 which makes it 50% chance.
Step-by-step explanation:
Which means the answer is 3/6
Answer:
Susan's dog weighs 9.75 pounds
Step-by-step explanation:
Given
The weight of Susan's cat = 3 pounds
Susan's dog weighs 3 1/4 or 13/4 times as much as her cat.
To determine
The weight of Susan's dog = ?
As the weight of Susan's cat = 3 pounds
Given that Susan's dog weighs 3 1/4 or 13/4 times as much as her cat. so
The weight of Susan's dog = 13/4 of 3
= 13/4 × 3
= 39/4
= 9.75 pounds
Therefore, Susan's dog weighs 9.75 pounds
Answer:
x=260 texts
Step-by-step explanation:
85=0.25x+20
Subtract 20 from each side.
65=0.25x
Divide both sides by 0.25.
260=x
260 texts plus the $20 flat fee will cost $85.
