Answer:
56 adults and 35 children
sum the parts of the ratio 16 + 10 = 26
Divide 91 by 26 to find one part of the ratio
= 3.5 ← 1 part of the ratio
16 parts = 16 × 3.5 = 56 ← number of adults
10 parts = 10 × 3.5 = 35 ← number of children

Hello!
to solve this problem, use the following equation
<span><span><span>(<span>4/3(3.141593)</span>)</span>(9^</span>3) </span>= <span>3053.628059</span><span>
so your final answer is:
the volume of the volleyball is </span>3053.628059<span>
I hope this helps, and have a nice day.</span>
Answer:
since the total amount of wire is not given, I looked for a similar question:
- you have 800 yards of wire at your disposal
since we need to only calculate 3 sides of the land plot, our perimeter will be:
L + 2W = 800
area = L x W
L = 800 - 2W
now we replace:
area = (800 - 2W) x W = 800W - W²
we can write a quadratic equation:
area = -W² + 800W
the vertix of W = -b/2a
the coefficients of our quadratic equation are: -2 and 8
the vertix of W = -800 / (2 x -2) = -800 / -4 = 200 yards
width = 200 yards
length = 800 - (200 x 2) = 400 yards
maximum area enclosed = 200 x 400 = 80,000 sq yards
Answer:
B. --4/-5
Step-by-step explanation:
negative sign will cancel and then one sign will remain that is -4/5.

Simplify 7x + 2y = -23
Solving
7x + 2y = -23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = -23 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = -23 + -2y
7x = -23 + -2y
Divide each side by '7'.
x = -3.285714286 + -0.2857142857y
Simplifying
x = -3.285714286 + -0.2857142857y
