➷ Simply substitute the values into the equations to see if it's correct:
Since the time taken will be more than 2 hours, we can try it with the value 3
t(x) = 70 + 5(3) = 85
g(x) = 30 + 15(3) = 75
As you can see, this is the incorrect choice as when a value more than 2 hours is used, the second engineer has a cheaper cost.

Answer:
29
Step-by-step explanation:
x+61=90
This is because they are complementary angles.
You can tell by the little square in the corner next to them
x=29
Well, we have linear terms (the heights and radii of the two cylinders) and cubic terms (the volume of the two cylinders). So, we need to cube the given ratio respective of their order.
2 -> to the power of 3 -> 2×2×2=8
3 -> to the power of 3 -> 3×3×3=27
Therefore, the ratio of the volumes of the two cylinders is 8:27. Your answer is D.
15/25 can be divided by 5 so it would be 3/5. Hope it helped!!!
