Lelu [443]

Answer:

B. $8

Step-by-step explanation:

Given:

Total payment, T = $160

Hourly rates = $t/hour

= total payment/total time worked

The question said, "worked 12 more hours than the amount she is paid per hour".

Total time worked = (12 + t) hour

Therefore, Hourly rates of payment, t = 160/(12 + t)

t^2 + 12t - 160 = 0

Solving the above quadratic equation,

t = -20 and 8

t = $8

Find the volume of a cylinder if the radius is 12 inches and the height is 17 inches

Alex Ar [27]

Answer:

Volume of the cylinder = $7686.72\,inches^3$

Step-by-step explanation:

Radius(r) of the cylinder= $12\,inches$

Height(h) of the cylinder= $17\,inches$

Volume of a cylinder is :

$\pi \times r^2\times h$

As,

$\pi =\dfrac{22}{7}=3.14$

Volume is:

$=3.14\times (12\times 12)\times 17\\\\=3.14\times 144 \times 17\\\\=3.14\times 2448\\\\=7686.72\,inches^3$

The volume of the cylinder is: $7686.72\,inches^3$
