Answer:
3 hours and 45 minutes
Step-by-step explanation:
let's assume the tank has a volume of x liters.
let's assume the speed of filling it is x/6 liters per hour for A and x/10 liters per hour for B.
the formula to calculate the time is:
time = volume / speed
If the pumps work together, the total speed is x/6 + x/10, which is 16/60 x
So the time this takes is:
time = x / (16/60 x) = 60/16 hours = 3.75 hours = 3 hours and 45 minutes.
A is commutative property
B is associative property
Explanation:
Answer:
y - 4 = 3(x - 1)
Step-by-step explanation:
It looks like you have slope 3 and a point (1, 4)
so it should be y - 4 = 3(x - 1)
which is your first choice: y minus 4 = 3 (x minus 1)
The answer is a square.
All four sides are congruent.
<u>Answer with step-by-step explanation:</u>
We know that the formula for area of a circle is given by:
<em>Area of a circle =
</em>
So to find the area of circle, we basically need to know the radius of the circle.
If we know the circumference of the circle, we can calculate the area of the circle too.
Formula for the circumference of the circle is given by:

So if we know the circle's circumference, we can find the value of radius and then find the area of circle with it.
