Question

Amerada Hess company wants to make an oil container tank. Engineers are shown a sample tank. which is 1 meter in height, and they are told that the new tank should look similar to the sample. If the sample tank is 1/25 the size of the original tank. what is the height of the original tank?
A. 25m
B. 20m
C. 10m
D. 1m

Answer 1

Since the sample is 1/25 the size and the size of the sample is 1m then:

$1 = \frac{1}{25} x$

x is the height of our container. we need to move 1/25 to the other side so we multiply both sides of the equation by 25.

$25 \times 1 = \frac{1}{25} x \times 25$

On the right side of the equation, 1/25 cancels out with 25 since:

$\frac{1}{25} \times 25 = 1$

so we are left with the 25 x 1 on the left:

$25 = x$

so the container is 25m; C.
