The amount of time it takes a water pump to empty a tank varles directly as the capacity of the tank. If it takes a water pump 2.5 hours to empty
a tank containing 60,000 gallons of water, how long does it take the same pump to empty a tank containing 108,000 gallons of water?

It will take {BLANK} hours to empty the second tank.

Answers

Answer: 4.5 hours

Step-by-step explanation:

First you put 60000 and change 2.5 hours into minutes then divide by that, inwhich you get 400. After getting 400 divide 108000 by 400 which equals 270, divide by 60 for hours.

It would take the same pump 4.5 hours to empty a tank containing 108,000 gallons of water.

What is an expression?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. An expression can also include mathematical functions, parentheses, and other symbols.

Let x be the amount of time (in hours) it takes the pump to empty a tank containing 108,000 gallons of water.

Using the direct variation formula, we can write:

time = k x capacity

Where k is the constant of variation.

We can use the given information to find k:

2.5 = k x 60000

k = 2.5 / 60000

k = 0.00004167

Now we can use this value of k to find x:

x = k x 108000

x = 4.5

Therefore, it would take the same pump 4.5 hours to empty a tank containing 108,000 gallons of water.

Which equation has no solution?
O l-2x + 81 = 0
O [3x + 61 = 6
o 14x - 2) = -6
O 1-2 - x| = 9

Answers

Answer: |4x-2|=-6

Step-by-step explanation:

This has no solution

The equation that has no solution is | 4x - 2 | = -6.

What is an equation?

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

| -2x + 8 | = 0: This equation has only one solution, which is x = 4. When we take the absolute value of any number, the result is always non-negative (i.e., greater than or equal to zero).

Therefore, the absolute value of -2x + 8 can only be zero if -2x + 8 itself is zero. Solving for x, we get x = 4.

| 3x + 6 | = 6: This equation has two possible solutions, which are x = 0 and x = -4. When we take the absolute value of 3x + 6, the result can be either positive or negative, depending on the value of x.

Therefore, we need to solve two separate equations: 3x + 6 = 6 and 3x + 6 = -6. Solving for x in each case, we get x = 0 and x = -4.

| 4x - 2 | = -6: As I mentioned in my previous answer, this equation has no solutions.

An absolute value cannot be negative or equal to a negative number, so there is no value of x that would make the left-hand side of the equation equal to -6.

| -2 - x | = 9: This equation has two possible solutions, which are x = -11 and x = 7. When we take the absolute value of -2 - x, the result can be either positive or negative, depending on the value of x.

Therefore, we need to solve two separate equations: -2 - x = 9 and -2 - x = -9. Solving for x in each case, we get x = -11 and x = 7.

Lily wants to buy a cow but can't afford the $25 it costs. Later in the year it is at an affordable $15 and Lily can buy it. What percentage of a
discount was on the cow? Please explain :)

Answers

Answer:

There was 60% discount on the cow.

Step-by-step explanation:

Cost of cow = $25Latest price = $15

Discount can be calculated by dividing the latest price by the original price and multiplying by 100.

Thus,

percentage discount = 15/25 × 100

                                   = 0.6 × 100

                                    = 60%

Thus, there was 60% discount on the cow.

An employee receives a 2% raise once per year. If the employee's initial salary is $52,400.00, What will the employee's salary be after 16 years?

Answers

The employee will receive a percentage raise after 16 years is $69,168

How to calculate the employee salary after 16 years ?

The first step is to calculate the percentage raise of the salary per year

= 2/100 × 52,400

= 0.02 × 52,400

= 1,048

The next step is to multiply 1,048 by the number of years

= 1048 × 16

= 16,768

The salary after 16 years can be calculated as follows

= 52,400 + 16,768

= 69,168

Hence the employee salary after 16 years is $69,168
