Answer:
Pair 1: 10 cm and 2 cm. and the sum is 12 cm.
Pair 2: 20 cm and 4 cm. and the sum is 24 cm.
Step-by-step explanation:
Area of a rectangle is given by A = LW, where L is the length and W is the width of the rectangle.
Pair 1:
For the first rectangle W = 4 cm and A = 40 sq, cm
Then 
cm.
For the second rectangle W = 4 cm and A = 8 sq, cm
Then 
cm.
Therefore, the sum of two unknown lengths = 10 + 2 = 12 cm. (Answer)
Pair 2:
For the first rectangle W = 4 cm and A = 80 sq, cm
Then 
cm.
For the second rectangle W = 4 cm and A = 16 sq, cm
Then 
cm.
Therefore, the sum of two unknown lengths = 20 + 4 = 24 cm. (Answer)
Answer:
512ft³
Step-by-step explanation:
A rectangular prism is made up of 32 cubes, each measuring 1 /4 of a foot per side. What is the volume of the rectangular prism?
Since we have 32 cubes with each side = 1/4 foot
= 32 × 1/4 foot
= 8
Hence, the volume of the rectangular prism = 8 × 8 × 8
= 512ft³
It would be 6 miles per hour.
mph is a unit for speed. And the formula for speed is s=distance /time
So the distance is 2 miles
And the time is 20 minutes
*for this question you need to convert the minutes to hours to get the right units
20mins =0.3 hours (approx) [20/60 to get it in hours]
2 miles/0.3 hours ≈ 6 mph
Answer:
the radius is half of the diameter so that would mean that the radius is 1 mile.
Step-by-step explanation:
Answer:
3
because 15 + 9 = 24
and 3(5 + 3) which is 3 * 5 + 3 * 3 = 15 + 9 = 24
= 24 = 24
