Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:
Which means that option E is correct.
The <em>volume of a cube</em> of side length l is given by:
For Cube A, the volume is of 9 cubic inches, hence:
![l_a = \sqrt[3]{9}](https://tex.z-dn.net/?f=l_a%20%3D%20%5Csqrt%5B3%5D%7B9%7D)
For Cube B, the volume is of 5 cubic inches, hence:
![l_b = \sqrt[3]{5}](https://tex.z-dn.net/?f=l_b%20%3D%20%5Csqrt%5B3%5D%7B5%7D)
Then, the ratio is:

Answer:
14 degrees.
Step-by-step explanation:
I am assuming that the 56 degree angle is at the centre of the circle.
The angle at the top in the circle = 1/2 * 56 = 28 degrees.
The reflex angle = 360 - 56 = 304 degrees.
If we draw a line from the vertex of the 56 degrees angle to the vertex of 28 degree angle we bisect the reflex angle and the 28 degree angle. Also the 2 triangles formed are congruent ( by SSS).
So x = 180 - 1/2 * 28 - 1/2 * 304
= 180 - 14 - 152
= 180 - 166
= 14 degrees.
Using proportions, it is found that the family will drive 482.8 km on the new route.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:
D = 1.25 x 240 = 300 miles.
Since there are are approximately <u>48.28 kilometers in 30 miles</u>, and 300/30 = 10, the distance in kilometers is given by:
D = 48.28 x 10 = 482.8 km.
