53.07 :P people are integers so about 53 representatives are from California (Precisely why we have a Senate with two from each state LOL)

Answer:

It took 5 hours to repair the car

Step-by-step explanation:

An auto repair shop charged a customer $349 to repair a car.

The bill listed $99 for parts and the remainder for labor.

The cost of labor is $50 per hour. If the number of hours it took to repair the car is x, then:

99 + 50x = 349

To find the number of hours it took to repair the car, we need to find x:

50x = 349 - 99

50x = 250

x = 250 / 50 = 5 hours

It took 5 hours to repair the car.

ira [324]

Answer:

B,5.4 units.

Step-by-step explanation:

Parallelogram RSTU

R(1,1),S(7,0),T(10,4),U(4,5)

slope of RU m=(5-1)/(4-1)=4/3

slope of RS=(0-1)/(7-1)=-1/6=-1/6

slope of ST=(4-0)/(10-7)=4/3

slope of TU=(5-4)/(4-10)=1/(-6)=-1/6

RU||ST

eq. of line RU is

y-y1=m(x-x1)

y-1=4/3(x-1)

3y-3=4x-4

4x-3y-4+3=0

4x-3y-1=0

perpendicular distance of a point (x1,y1) from line ax+by+c=0 is

$d=\frac{ax1+by1+c}{\sqrt{a^2+b^2} } \\$

perpendicular distance of (7,0) from 4x-3y-1=0

$d=\frac{4(7)-3(0)-1}{\sqrt{4^2+(-3)^2} } \\=\frac{28-1}{\sqrt{16+9} }\\=\frac{27}{5} \\=5.4~units$
