<span>This problem is an
example of ratio and proportion. A ratio is a comparison between two different
things. You are given the equivalent distance of a 1 2/5
kilometers to 1 mile. Also you are given 4 miles. You are required to find the distance
in kilometers of 4 miles. The solution of this problem is,</span>
1 2/5
kilometers /1 mile = distance/ 4 miles
distance = (4
miles) (1 2/5 kilometers /1 mile)
<u>distance =
28/5 or 5.6 kilometers</u>
<u>There are 5.6
kilometers in 4 miles.</u>
Answer:
The missing side is 9cm.
How I got my answer:
1. Squares have equal sides.
2. The area is 81cm^2, so we have to divide 81 by 9.
81 : 9 = 9cm.
Answer:
[you need 343 1 inch cubes]
Step-by-step explanation:
A foot has 12 inches. So if the edge length is 7/12 of a foot, that means that the edge length is 7 inches.
——————
[volume of a cube if the edge length is L, is L x L x L or L cubed]
A one inch cube has an edge length of 1. That means the volume of this cube is 1 x 1 x 1 = 1 inch cubed
——————
This big cube, has an edge length of 7 inches. So the volume is 7 x 7 x 7 = 343 inches cubed.
To find how many 1 inch cubes do you need to fill a 7 inch cube, you divide 343 by 1:
343/1=343 so you need 343 1 inch cubes.
You made the choice to choose the letter A, a second time.
