Answer:
y = 27
Step-by-step explanation:
The given are two similar triangles.
We can use the following equation to find the variables:
Cross multiply fractions
32*18 = 24(y-3)
576 = 24y - 72
add 72 to both sides
648 = 24y
divide both sides by 24
27 = y
Answer:
3 miles per hour.
Step-by-step explanation:
To get his walking rate in miles per hour, we multiply 1/5 by its reciprocal, 5/1. We also multiply 6/10 by 5/1. This gets us 30/10 of a mile in an hour. We can simplify 30/10 to 3. This means he walks at 3 miles per hour.
Answer:
4
Step-by-step explanation:
360 deg = 20
1 deg = 20/360
72 deg = 20/360 * 72 = 4
Step-by-step explanation:
V = s^3 , so to find each side we need to find the cube root of 27
cube root of 27 = 3
therefore each edge is 3meters long
