Marcus earns $8.40 per hour. He works for 26 hours each week, 48 weeks each year. If he earns over $10,000, then Marcus has to p
MAVERICK [17]

We have been given that Marcus works for 26 hours each week and 48 weeks each year.

Thus in a year he works for 26 \times 48 = 1248 hours.

Now, we have been given that Marcus earns $8.40 per hour.

Therefore, in 1248 hours, he earns

1248 \times 8.40\\
\\
=\$ 10483.2

Marcus has to pay tax if he earns more than $10,000. Now we have calculated that he earns $ 10483.2  which is higher than $10,000.

Therefore, Marcus has to to pat tax.

Answer:

C) 35

Step-by-step explanation:

^7C_3 \\  =   \frac{7!}{3!(7 - 3)!}  \\=   \frac{7!}{3! \: 4!}   \\ =   \frac{7 \times 6 \times 5 \times 4!}{3 \times 2 \times 1 \times   4!}  \\ =   \frac{7 \times 6 \times 5 \times 4!}{3 \times 2 \times 1 \times   4!}    \\ = 35 \\ \huge \red{ \boxed{  \therefore \: ^7C_3  = 35}}

8. Line AB passes through A(-2,4) and B(-8,-6).
netineya [11]

Answer:

AB : \frac{5}{3}

PT : -\frac{1}{5}

Step-by-step explanation:

The line AB passes through A(-2,4) and B(-8,-6) points.

Therefore, the slope of the line AB will be \frac{4-(-6)}{-2-(-8)} =\frac{5}{3} (Answer)

Again line PT passes through P(3,-1) and T(8,-2) points.

Therefore, the slope of the line PT will be \frac{-1-(-2)}{3-8} =-\frac{1}{5}. (Answer)

Here we have applied the formula of slope of a straight line passing through the points (x_{1},y_{1}) and (x_{2},y_{2}  ) as given by \frac{y_{1}-y_{2}  }{x_{1}-x_{2}  }.
