3^4 = 3 * 3 * 3 * 3 = 81
<span>2 ⋅ 5 = 10
81 + 10 = 91
The answer is 91.</span>
So 60% of the class are boys, but we're given the number of girl students. We know that the remaining 40% of the class are girls, which equals 12 students. To find out the total number of students in the class we can divide the number we're given into 10%, which we can then multiply to give 100%.
So 40% of the class equals 12 students, we divide by 4 to give 10%, so 12 ÷ 4 = 3. So 10% of the total class is 3 students, we times by 10 to find 100% of the class, so 3 x 10 = 30 students.
The sum of interior angles of any polygon is:
s=180(n-2)
Since we are dealing with a triangle:
s=180(3-2)
s=180°
That is, the sum of angles of any triangle is 180°.
In this case we are given two angles with measures of 32° and 102° so
a+b+c=180
32+b+102=180 combine like terms on left
b+134=180 subtract 134 from both sides
b=46°
Answer:
The radius of the ball is of 6 feet.
Step-by-step explanation:
The radius of the ball in spheric format is given by:
In which r is the radius.
A water-walking ball has a volume of approximately 904.32 cubic feet. What is the radius of the ball?
Volume in cubic feet, so the radius will be in feet. We have to find r for which 
. So
![r = \sqrt[3]{\frac{904.32*3}{4\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B904.32%2A3%7D%7B4%5Cpi%7D%7D)
The radius of the ball is of 6 feet.
