Mr. Powell brought home $324.16 in net pay last week. His gross pay was $594.00. His net pay is what percent of his gross pay? 60%
55%
183%
18%

Answers

His net pay as a percent of his gross pay is 324.16/594.00 x 100 = 55%

Mr. Powell brought home $324.16 in net pay last week. His gross pay was $594.00. Then

$594 -- 100%,

$324.16 -- x%,

or mathematically it sounds as proportion:

$(\$594)/(\$324.16)=(100\%)/(x\%).$

Find x:

$x\%=(\$324.16\cdot 100\%)/(\$594)\approx 55\%$

Answer: correct choice is B

How many leaves on a tree diagram are needed to represent all possible combinations tossing a coin 4 times?

Answers

Answer with explanation:

When you toss a coin once , total possible outcome =2={H, T}

When you toss a coin twice , total possible outcome =2²=4={HT,TH,T T,H H}

When you toss a coin thrice , total possible outcome =2³=8

={T T T,T TH, T HT,H T T,H HT,H TH,T H H,H H H}

When you toss a coin 4 times , total possible outcome

$2^4=16$

={T T T T, T T TH, H T T T,T H T T,T T HT,T T H H,H H T T,T H HT,H T TH,H TH T,T H TH, H H HT,H T H H,TH H H,H H TH,H H H H}

=16

There are 16 possible outcomes in all.

So, total number of leaves needed on the tree Diagram = 16 Leaves

1/2 x 1/2 x 1/2 x 1/2 = 1/16

Answer: 16

describe how the problem 24000/50 could be solved without dividing 24000/5, then find the answer. help pls

Answers

Write 24000 as the numerator and 50 as the denominator: 24000/50.

Notice that both the numerator and denominator have a common factor of 50.

Divide both the numerator and denominator by 50 to simplify the fraction:

(24000 / 50) / 50 = (24000 ÷ 50) / (50 ÷ 50) = 480 / 1

So, 24000/50 simplifies to 480/1, which is just 480 as a whole number. Therefore, 24000/50 = 480.

Dividing by 50 is the same as multiplying by 1/50, which is equivalent to 2/100.

The fraction 2/100 means we'll double 24000 to get 48000. Then remove 2 zeros at the end to get 480. The removal of two 0's is due to the division by 100.

Therefore, 24000/50 = 480

---------------

Dividing by 5 will follow a similar pathway. We can multiply by 1/5 aka 2/10

24000/5 = 24000*(1/5) = 24000*(2/10) = 48000/10 = 4800

Notice the numerator doubled to 48000, and then we remove a zero at the end.

All of this can be done using pure mental math only. Each answer can be confirmed with a calculator.

Give a real-world scenario in which you would write an inequality rather than an equation.

Example: You have some money in your pocket. You want to buy some snacks for tonight's match but your wife told you to buy one pizza on your way back to home that costs $10. That means that on snacks you can spend (y) :
y ≤ x - 10 where x represents money in your pocket.

This means that from money in your pocket you have to subtract $10 for pizza and out of remaining money you can spend some part of it on snacks or all of it.
