Genrish500 [490]

Answer:

The height of the container is 4 feet.

Step-by-step explanation:

A container has the format of a rectangular prism.

It has three dimensions: width(w), length(l), height(h).

The volume is:

V = w*l*h

In this question:

w = 45, l = 50, V = 9000

We have to find the height(length and width are in feet, volume in cubic feet, so the height will be in feet).

V = w*l*h

9000 = 45*50*h

h = \frac{9000}{45*50}

h = 4

The height of the container is 4 feet.

A man invests $16 800 in a saving plan that pays simple interest at a rate of 5%. Find the time taken for his investment to grow
san4es73 [151]

Answer:

  • 2.5 years

Step-by-step explanation:

<u>Given</u>

  • Investment P = $16800
  • Interest rate r = 5% = 0.05
  • Final amount A = $18900
  • Time t = ?

<u>Use the formula</u>

  • A = P(1 + rt), where A - final amount, P - investment, r- interest rate, t- time

<u>Substitute the given numbers and solve for t:</u>

  • 18900 = 16800( 1 + 0.05t)
  • 1 + 0.05t = 18900/16800
  • 1 + 0.05t  = 1.125
  • 0,05t = 0.125
  • t = 0.125/0.05
  • t = 2.5 years
