Answer:

16.   30 * (30+12)/4*(L)*20

17.  Volume = 6300 * Length of rectangular prism

Step-by-step explanation:

The width of a rectangular prism is <u>30 cm</u>. This is  <u>12 more than one-fourth of the length</u>. Find the  volume of the prism, given the <u>height is 20 cm</u>.

Let L = length of rectangular prisim W = width and H = height

16.  

Volume of a rectangular prism is width * length * height

30 * (30+12)/4*(L)*20

17.  

= 30 * (30+12)1/4(L)*20

= 30 * (42/4)*L * 20

= 600 * 10.5 * L

= 6300 * L

Volume = 6300 * Length of rectangular prism

What is the midpoint of a line segment with the endpoints (-4, -3) and (7, -5)
Katyanochek1 [597]
Midpoint Formula: (\frac{x+x}{2},\frac{y+y}{2})
Midpoint = (\frac {-4+7}{2},\frac {-3-5}{2})
Midpoint = (\frac {3}{2},\frac {-8}{2})
Midpoint = (\frac {3}{2}, -4)
So, the midpoint of the endpoints (-4,-3) and (7,-5) is (\frac {3}{2}, -4).

Amanda [17]

Answer: 6,160,000 db

Step-by-step explanation:

The sound of a jet engine is 70,000 times louder than that of a lawn mower.

Since we know the sound of a lawnmower, we can multiply that by 70,000 to find the sound of a jet engine:

= Sound of lawnmower * 70,000

= 88 * 70,000

= 6,160,000 db
