Answer:</u></h2>
The roofing company can take out <u>196.352kg</u> of shingles.
<h2><u>
Step-by-step explanation:</u></h2>
- First, work out how many 90 minutes are in 39 hours:
39 x 60 = 2340 minutes total
2340 ÷ 90 = <u>26</u>
- Then, multiply this by 755.2 to work out how much hectograms of trash is taken out.
26 x 755.2 = <u>19635.2 hectograms of trash</u>
- Finally, divide this by 10 to work out how many kilograms this is:
19635.2 ÷ 10 = <u>196.352kg</u>
Answer:
Step-by-step explanation:
Let the speed of current be x
<u>Speed of the boat in same direction as current is</u>
<u>Speed against the current is</u>
<u>Based on the given we get the equation for time</u>
<u>Solving for x</u>
- 6(10 - x) = 4(10 + x)
- 60 - 6x = 40 + 4x
- 6x + 4x = 60 - 40
- 10x = 20
- x = 2
The answer is 2 mph
Answer:
-4.3
Step-by-step explanation:
a+(-1.2)= -5.5
a-1.2=-5.5

a-1.2+1.2= - 5.5+1.2
simplify
a= - 4.3
