Answer:
Step-by-step explanation:
Let's say
d1 the outflow of the first pump
d2 the outflow of the second pump
V=1 is the volume of the tank
Since the second pump takes twice as long as the first to fill the tank,

Two pumps can fill a pool tank in 26 hours when working together:

How long does it take the first pump alone to fill the tank:

Well 4^m*4^n can be added so lets say you have 4^4*4^6 that would just be adding the exponets to get 4^10. but (4^m)^n that is multiplying the exponet of 4 to n so (4^6)^4 would be 4^24.

I attached an image of how to do the division. It is kind of difficult to explain like this.
Answer:
$1875
Step-by-step explanation:
Given the information:
- An apartment costs: $625 per month
- They require that the cost of rent be no greater that a third of his monthly income
- The must earn at least 3 times the cost of his rent
=> the smallest amount of money that Carlos needs to make per month to be approved to move in:
= 3 times of $625
= 3*$625
= $1875
because 625 is exactly 1/3 of $1875
Hope it will find you well.
Answer:
26
Step-by-step explanation:
W = ∫ f(x) dx
W = ∫₁³ (3x + 7) dx
W = (1.5x² + 7x) |₁³
W = (1.5(3)² + 7(3)) − (1.5(1)² + 7(1))
W = 26
