Aniya states that the quotient of -5 divided by 20 is an irrational number. Explain if you agree or disagree with her statement.
pochemuha

Answer:

-5 divided by 20 isn't an irrational number because the quotient of that problem equals -0.25. If the decimal form of a number stops or repeats, the number is rational. If the decimal does not stop and does not repeat, the number is irrational. Therefore, since -0.25 stops, it is a rational number, and not an irrational number.

Step-by-step explanation:

Sorry if the explanation isn't good, or there are some grammar mistakes. But i hope this helps :)

Solve the equation<br> 15x+2=45x+4
BaLLatris [955]
15x + 2 = 45x + 4

Subtract 2 from both sides, as well as subtracting 45x from both sides.

15x - 45x = 4 - 2

-30x = 2

Divide both sides by -30.

x = 2/-30

x = - 1/15

~Hope I helped!~

Based on a 4-week work month and a 40-hour
Leni [432]

Answer:

$27.69

Step-by-step explanation:

Given

Monthly budget (See attachment)

Month = 4\ weeks

Week = 40 \ hour

Required

Determine the closest hourly wage

From the attachment, the monthly budget is:

Budget = \$ 4430

First, we calculate the closest weekly earnings.

Since a month = 4 weeks.

Then

Weekly\ Earnings = \frac{\$4430}{4}

Weekly\ Earnings = \$1107.5

Next, we calculate the hourly earnings:

Since 1 week = 40 hour

Then

Hourly\ Earnings = \frac{\$1107.5}{40}

Hourly\ Earnings = \$27.6875

<em>From the list of options, the closest is: $27.69</em>
