Answer:

Mark owes Kira $2.

Step-by-step explanation:

The correct answer is “Mark owes Kira $2” because first Kira owes $5 to the Mark and then Mark gives $7 to Kira. Here it can be seen that Mark is giving $2 extra and $5 is the amount which he is refunding. So the net amount $2 that the Mark gives to Kira. Therefore, the statement “Mark owes Kira $2” is justified and correct.

A 72,000 gallon water tower is being drained. Two thousand gallons are drained in the first hour. How many hours will it take to

ololo11 [35]

Answer:

To drain the water tower it will take 36 hours.

Step-by-step explanation:

Given:

A 72,000 water tower is being drained, and in an hour 2000 gallons are drained.

Now, to calculate the hours it would take to drain total 72,000 gallons of water, we should divide the gallons of water drained in one hour by total gallons of water in the tower.

Gallons of total water in the tower ÷ Gallons of water drained per hour

$72000\div 2000$

$=\ 36$

Therefore, to drain the water tower it will take 36 hours.

In a recent year, 27.9% of all registered doctors were female. If there were 53,700 female registered doctors that year, what wa

Elis [28]

Answer:

The total number of registered doctors was 192,473.

Step-by-step explanation:

This question can be solved using a rule of three.

53700 is 27.9% = 0.279. The total number of registered doctors is x, which is 100% = 1. So

53700 doctors - 0.279

x doctors - 1

$0.279x = 53700$

$x = \frac{53700}{0.279}$

$x = 192473.11$

Rounding to the nearest whole number.

The total number of registered doctors was 192,473.

QRST is a parallelogram. Find x and y.

Wewaii [24]

In parallelograms, opposite sides are congruent, meaning that they are the same lengths. So, we have:

y - 4x = 9

-x + 4 = y

Add x to both sides of the second equation:

y + x = 4

y - 4x = 9

This is a system of linear equations. Solve by eliminating the y and subtracting the two equations:

5x = -5

x = -1

Use x to solve for y:

y + (-1) = 4

y = 5

So, x = -1 and y = 5.
