So,

#1: \frac{5}{8}

We know that \frac{1}{8} = 0.125, or 12.5%.
Therefore, we just have to multiply 12.5% by 5 to get \frac{5}{8}  in percent form.

12.5(5) = 62.5

\frac{5}{8}  as a percent is 62.5%.


#2: 2  \frac{4}{7}

2 \frac{4}{7} = 200% + \frac{4}{7}

4/7 rounded to the nearest thousandth is 0.5714, or 57.14%.

200% + 57.14% = 257.14%

Dana and Monique are dog groomers. Dana’s workday is 10 hours and Monique’s workday is 8 hours. Dana and Monique each work 40 ho
Lana71 [14]

Answer:

$127.50

Step-by-step explanation:

To answer this you will need to figure out how many days each person is working each week based on their number of hours and how many hours they work.  Use this to determine the number of dogs groomed and then multiply by the hourly rate.

Dana works 4 days (40/10) and Monique works 5 days (40/8).

Dana:  15 dogs per day x 4 days a week x $12.75 per dog = $765 a week.

Monique: 10 dogs per day x 5 days a week x $12.75 per dog = $637.50 a week.

765 - 637.50 = $127.50.

The difference is $127.50.

A car is traveling at a steady speed. It travels 2 1/2
Ksivusya [100]

Answer:

It will travel

33 \frac{1}{4}  \: miles

in 45 minutes.

Step-by-step explanation:

We can solve using proportions.

\frac{ 2\frac{1}{2} \: miles}{ 3\frac{1}{3} \: minutes}  =  \frac{x}{45 \: minutes} \\  \\  \frac{ 3\frac{1}{3} x}{ 3\frac{1}{3} }  =   \frac{ 112\frac{1}{2} }{ 3\frac{1}{3} }    \\  \\  x = 33\frac{3}{4}

Mathematical Statement Justification
olya-2409 [2.1K]

Answer:

B

Step-by-step explanation:

1. Given mathematical statement

4x+3=x+5-2x

So,

\begin{array}{cc}4x+3=x+5-2x&\text{ Given}\end{array}

2. Rewrite it as

4x+3=x-2x+5

So,

\begin{array}{cc}4x+3=x-2x+5&\text{ Commutative property of addition}\end{array}

3. Combine like terms x and -2x:

4x+3=-x+5

So,

\begin{array}{cc}4x+3=-x+5&\text{ Combine like terms}\end{array}

4. Add x to both sides:

4x+3+x=-x+5+x\\ \\5x+3=5

So,

\begin{array}{cc}5x+3=5&\text{ Addition property of equality}\end{array}

5. Subtract 3 from both sides:

5x+3-3=5-3\\ \\5x=2

So,

\begin{array}{cc}5x=2&\text{ Subtraction property of equality}\end{array}

6. Divide both sides by 5:

x=\dfrac{2}{5}

So,

\begin{array}{cc}x=\dfrac{2}{5}&\text{ Division property of equality}\end{array}
