Volume of sphere is given by:
V=4/3πr³
thus the value of r will be found as follows:
Plug in the values we get:
18432π=4/3πr³
solving for r we get:
r³=13824
r=∛13824
r=24 ft
The actual number of respondents corresponding to the given percentage is 57.
<h3>What do percentages mean?</h3>
Percentage is the fraction of an amount expressed as a number out of 100. The sign used to rerepresnt percentages is %. Percentages are a measure of frequency.
<h3>What is the number of respondents?</h3>

It makes a 74 degree angle.
The sides of the triangle that are given are the side adjacent to the angle the ladder makes with the ground and the hypotenuse of the triangle.
adjacent/hypotenuse is the ratio for cosine:
cos x = 7/25
To solve this, we will take the inverse cosine:
x = cos⁻¹(7/25) = 73.7 = 74
Answer: D
Step-by-step explanation:
Let's take one of the equations and solve for a variable to use the substitution method.
Now replace this in the first equation.
Separate the terms.
Solve 20/5
Subtract 4 from both sides to isolate y.
Solve the difference.
Multiply by the reciprocal or the inverted fraction that is next to y to isolate it.
Now, in order to find x, replace y in any of the two equations.
Answer:
width
Step-by-step explanation:
