Answer:

The mechanic charged 40 for the labor per hour.

Step-by-step explanation:

Total bill paid = 375

Working hours of labor =  4 hrs

Also, the additional charges paid on the bill = 215

So, the actual labor charge paid for 4 hour labor

Actual labor Cost  =  Final Bill - Additional charges

= 375 - 215 = 160

Hence, the cost paid for 4 hour labor = 160

⇒ The cost paid for 1 hour labor = 160 / 4 = 40

Or, the mechanic charged 40 for the labor per hour.

Otrada [13]

Answer:

h ≈ 9.9 cm

Step-by-step explanation:

By applying tangent rule for the given angle in the given right triangle,

tan(51°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

tan(51°) = \frac{h}{8}

h = 8 × tan(51°)

h = 9.879

h ≈ 9.9 cm

Therefore, measure of side 'h' is 9.9 cm.

What is the missing step in solving the inequality 5 – 8x &lt; 2x + 3? Add 2x to both sides of the inequality. Subtract 8x from
kvasek [131]

Answer:

⇒ Add 8x to both sides of the inequality

⇒ x>1/5

Step-by-step explanation:

First, you subtract by 5 from both sides of equation.

5-8x-5<2x+3-5

Solve.

-8x<2x-2

Then subtract by 2x from both sides of equation.

-8x-2x<2x-2-2x

Solve.

-10x<-2

Multiply by -1 from both sides of equation.

(-10x)(-1)>(-2)(-1)

Solve.

10x>2

Divide by 10 from both sides of equation.

10x/10>2/10

Solve to find the answer.

2/10=10/2=5 2/2=1=1/5

x>1/5 is final answer.

Hope this helps!
