Answer:
D. 25 ft.
Step-by-step explanation:
To find the missing length of any right triangle, you can use the Pythagorean Theorem (A^2+B^2=C^2) to solve. A and B represent the legs (which we do have) and C represents the hypotenuse (which we are trying to find). Insert our known values into the theorem, and we will get 24^2+7^2=C^2. Now we just do the basic math for the numbers that we have (24^2 is 576<em>;</em><em> </em>7^2 is 49), and that added up would equal to 625. Now, since C is being squared on the other side, we now have to root both sides. On the side where C is, the radical and the square will cancel out each other, leaving us with just C. But, on the side where 625 is, it should root to 25. Since C is by itself now, the number on the other side (25) will be our answer. Therefore, the missing side is 25 feet long.
The area of the portion of S lying outside R is 63xy
<h3>What is a Rectangle ?</h3>
A rectangle is a polygon with four sides , four angles and four vertices , It has opposite sides parallel and equal.
It is given in the question that
A rectangle R has width x and length y.
A rectangle S is formed from R by multiplying each of the sides of rectangle R by 8
Area of R is xy
Area of S is 8x * 8y = 64xy
The area of the portion of S lying outside = 64xy - xy = 63xy

Let
n = number of data
s = standard deviation (sample)
S = standard deviation (population)
The working equations is
To find
, : (1 - 0.90)/2 = 0.05
To find
, : 1 - 0.05 = 0.95
Degrees of freedom = n-1 = 24 - 1 = 23
This is shown in the figure attached. Since there is no row for df=23, we interpolate. Thus,
Substitute all values,
Thus the answer is,
Yes because their both 90° angle triangles
Volume = length x Base x height
3240 = 18 x 12 x H
3240 = 216 x H
H = 3240 / 216 = 15 inches
