Answer:
16
Step-by-step explanation:
The formula to find the volume of the right angle rectangular prism is:
V = h*w*l where:
= 4*8*2 = 64 cubic inches
Let V1 in cubic inches is the volume of the big rectangular prism
In the question, she made smaller rectangular prism using 1/4 of the number of cubes so the volume in cubic inches of the smaller right rectangular prism:
1/4 the Volume of of the big rectangular prism
= 1/4 V1
= 1/4*64 = 16
Hope it will find you well.
Answer:
x = 10.52 m
Step-by-step explanation:
Given that,
Length of a park = 90 m
Width of a park = 60 m
Area, A = 9000 m²
A uniform strip borders all four sides of the park for parking. We need to find the width of the strip. Let it is x. Now the area becomes,
(90+2x)(60+2x) = 9000
So, the width of the strip is equal to 10.52 m.
Answer:
The number of meters Robert will beat Sam is 12 meters.
Step-by-step explanation:
Given:
When Paul crossed the finish line of a 60-meter race, he was ahead of Robert by 10 meters and ahead of Sam by 20 meters. Suppose Robert and Sam continue to race to the finish line without changing their rates of speed.
Find:
the number of meters by which Robert will beat Sam
Step 1 of 1
When Paul finishes, Robert has run 60-10=50 meters and Sam has run 60-20=40 meters.
Therefore, when Robert and Sam run for the same amount of time, Sam covers of the distance that Robert covers. So, while Robert runs the final 10 meters of the race, Sam runs
meters.
This means Robert's lead over Sam increases by 2 more meters, and he beats Sam by 10+2=12 meters.
