The first thing that we are going to do in passing everything to the same unit.
We have then:
Cube A:
7 * (1 / 3.28) = 2.13 m
Cube B:
2 m
The surface area of a cube is:
A = 6 * L ^ 2
Where,
L: side
Since cube A has a longer side (2.13m) then it will have the largest surface area.
Answer:
Cube A has the larger surface area
Answer:
Therefore 160 workers needed to build 16 miles of highway in 15 weeks.
Step-by-step explanation:
Given that,
the amount of time to build a highway varies inversely with the number of workers and varies directly with the length of the highway.
i.e
T= time, L= length of highway and W= number of workers.
So,we can rewrite the above equation
Here, = 100 worker, = 4 miles, = 15 weeks
= ?, = 16 miles, = 15 weeks
[ Multiply both sides]
Therefore to build 16 miles of highway in 15 weeks 160 workers needed.
The expanded form for 3.69 is 3+0.6+0.09. How you do that is because the three is a whole number so it stays a whole number, the 6 is in the tenths spot and so it would be 0.6 because that is counting tenths. The 9 is in the hundredths spot so it has to be in expanded form as hundredths. And 2 spots over is hundredths so that is how you get that 9 in expanded form.
It is 9 inches because 54 divided by 6 is 9
