Ugo [173]

Answer:

divide this amount ($88.26875) by the number of people

Step-by-step explanation:

6.75% of $72.50 is 4.89375

15% of $72.50 is 10.875

What is an equation of the line that passes through the point (2, 4 and is perpendicular to the line whose equation is 3y = 6x 3
Maru [420]
Perpendicular line always have slopes that are negative reciprocals of one another.  Mathematically,

m1*m2=-1

So to be perpendicular to the line given, let's rearrange it to the point slope form of a line...

3y=6x ?3 (not sure what you wanted to type there)

anyway isolating y by dividing both side by three will leave 2x where 2 is the slope.

So for the other line to be perpendicular, m*2=-1, m=-1/2, now we have:

y=-x/2 +b, we can now you the point given to solve for b

4=-2/2 +b

4=-1+b

b=5 so

y=-x/2 +5 or more neatly

y=(10-x)/2

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.

Christiana works at Texas Road House and makes $50 each night in tips plus $7.50 per hour. Write a function rule in function not
LekaFEV [45]

Answer: M =  50 + 7.50 h

Step-by-step explanation:

As per the given scenario,

Total money Christina made = (Money she made in tips) + (Per hour wage ) x (Number of hours she work in one night)   (i)

Let M is the total money she makes and h is the number of hours she works in one night.

Here, Money she made in tips = $ 50

Per hour wage = $7.50

So substitute all the values in (i), we get

M =  50 + 7.50 h

Hence, the required function is M =  50 + 7.50 h.
