The following annual expenses for car insurance, vacation, and home repairs for the Clark family are $1130, $700, and $468, resp
eimsori [14]

Answer:

A) $192

Step-by-step explanation:

Given:

Yearly expense of Car insurance = $1130

Yearly expense of Vacation = $700

Yearly expense of home repairs = $468

we need to find the monthly allowance of Clark family.

First we find the total annual expense of Clark family.

Total Annual expense is equal to sum of Yearly expense of Car insurance and  Yearly expense of Vacation and Yearly expense of home repairs.

Framing in equation form we get;

Total annual expense = \$1130 + \$700+\$468 = \$2298

Now we know that;

Number of months in a year = 12 months.

Total Monthly allowance will be equal to Total annual expense divided by Number of months in year.

Framing the equation we get;

Total Monthly allowance  = \frac{\$2298}{12}= \$191.5

Rounding to nearest dollar we get;

Total Monthly allowance of Clark family is $192.

dsp73

Answer:

1\frac{1}{3}

Step-by-step explanation:

Total Volume of Water = 5\frac{4}{6}

Volume drunk by James =1\frac{1}{3}

Volume drunk by Simon =\frac{2}{3}

Volume drunk by Matthew = 1\frac{1}{2}

Volume drunk by Gilbert =\frac{5}{6}

Total Volume Drunk (i.e. The Sum) = 1\frac{1}{3} + \frac{2}{3} + 1\frac{1}{2} +\frac{5}{6}=\frac{13}{3}

Volume of water Left = Total Volume of Water-Total Volume Drunk

= 5\frac{4}{6}-\frac{13}{3} =\frac{4}{3}=1\frac{1}{3}

Anna11 [10]

Answer:

10 boys, 15 girls

Step-by-step explanation:

Original ratio: 2 boys/3 girls

let x be the scale factor of the ratio

2x plus 5 boys over 3x girls = 1 (because the # of boys/girls are the same)-------> 2x+5/3x = 1

Simplify: 2x+5=3x

Simplify: 5=x

plug x back into the original ratio: 10/15

Check: 10/15 = 2/3

10 boys + 5 boys = 15, 15/15 = 1
