Answer:
140%
Step-by-step explanation:
To write a percentage we need a number over 100.
We can first set up two ratios:
![\frac{35}{25}=\frac{x}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B25%7D%3D%5Cfrac%7Bx%7D%7B100%7D%20%20)
We can solve using cross multiplication (multiply the numerator of the first fraction with the denominator of the second fraction and multiply the numerator of the second fraction with the denominator of the first fraction)
3500=25x
Divide both sides by 25 to isolate x
x=140
140%
31. It gives you the equation f(x) = -2x + 4 and asks you to solve for f(12). To solve this you must replace x in the equation -2x + 4 with 12 like so:
-2(12) + 4
Remember that when solving this use your rules of PEMDAS. In this case you will first multiply -2 and 12 then add the product with 4
-24 + 4
f(12) = -20
33. Replace x in the equation x³ - x with 5 like so...
5³ - 5
Again, remember to use the rules of PEMDAS to solve this. First take the cube of 5 then subtract 5 from the answer
125 - 5
g(5) = 120

X = half width of tent
Tan(40) = 6/x
x = 6/Tan(40) = 7.15
2x = 14.30 feet the width of the tent

Answer:
33.5 cubic inches.
Step-by-step explanation:
If the softball fits perfectly inside the cubical box, the softball is a sphere with diameter of 4 inches (radius os 2 inches).
The volume of a sphere is given by:
![V= \frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
For r = 2 inches:
![V= \frac{4}{3}*3.14* 2^3\\V=33.5\ in^3](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B4%7D%7B3%7D%2A3.14%2A%202%5E3%5C%5CV%3D33.5%5C%20in%5E3)
The volume of the softball is 33.5 cubic inches.
