A weeks consists of 7 days, so we have to multiply the daily rate by 7:

$\dfrac{7}{8}\cdot 7 = \dfrac{49}{8}=6.125$

1 hour = 60 mins
7/8(60) = 52.5 minutes per day
In a week: 52.5(7) = 367.5 mins
367.5/60 = 6 1/8
Therefore, he watches tv for 6 1/8 hours

If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)

cricket20 [7]

Answer:

Area of the circle = $113.04\;units^2$

Step-by-step explanation:

Circumference = $37.68\;units$

Circumference of the circle = $2\times \pi \times r$

As,

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

$37.68=2\times \pi \times r\\\\37.68=2\times 3.14 \times r\\\\37.68=6.28\times r\\\\r=\dfrac{37.68}{6.28} \\\\r=6\;units$

Area of a circle = $\pi \times r^2$

$=3.14\times (6\times 6)\\\\=3.14\times 36\\\\=113.04\;units^2$

Alexxx [7]

$\frac{x}{2} + \frac{7}{9x}$
$= \frac{x*9x}{2*9x} + \frac{7*2}{9x*2}$
$= \frac{9x^2}{18x} + \frac{14}{18x}$
$= \frac{9x^2+14}{18x}$

Therefore the answer is B.
