Auto-Check Motors charged Mr. Jones $84.00 for an automotive part plus $68.00 per hour that a mechanic worked to install the par

avanturin [10]

You're going to want to take the total, which is $353.00 and subtract the initial cost, which is $84.00, the number now should be $269. Using that total divide it by $68.00, there you should find your answer of about 4 hours. The precise answer is 3.99588235. But you would round that to 4 hours.

What is the area of a semi circle that has a diameter of 1 1/2?

SVEN [57.7K]

Answer:

$A=0.8836$

Step-by-step explanation:

Area of circle:

$\pi r^2$

By using the area of a circle, we can get the area of a semicircle:

$\frac{\pi r^2}{2}$

Let's convert the mixed fraction to an improper fraction and then a decimal:

$1\frac{1}{2}$ = $\frac{3}{2}$ = $1.5$

Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

$\frac{1.5}{2} =0.75$

Now we have the radius, so we can plug in our values and find the area:

$\frac{\pi0.75^2}{2} = 0.88357293$

$A=0.88357293$

abruzzese [7]

$-\frac{157}{20}=-\frac{140+17}{20}=-\left(\frac{140}{20}+\frac{17}{20}\right)=-7\frac{17}{20}\\\\-7\frac{17}{20}\to\ divide\ 17\ by\ 20\to\boxed{-7\frac{17}{20}=-7.85}\\\\other\ way\\\\-7\frac{17}{20}=-7\frac{17\cdot5}{20\cdot5}=-7\frac{85}{100}=\boxed{-7.85}$
