3. Which of the following can find 76 / 4
The correct answer is A. (2*38) / (2*2)
because you are factoring 76 and 4 and factoring out a 2 from both of them. You can later eliminate the 2s to divide 38 by 2 which is a lot easier.

4. is correct. Good job!

5. Which of the following equals 10
Your answer:
{10}^{0}
would not be correct because anything to the power of 0 is 1.
The correct answer is
{10}^{1}
Because anything to the power of 1 is itself.

6. What is
2 \frac{1}{8}  +3 \frac{1}{2}  + 2 \frac{1}{2}
To add these fractions we need to have the same denominator and we do this by finding to LCD- the lowest commen denominator which is 8 in this case.
3 \frac{1}{2}  = 3 \frac{4}{8}
2 \frac{1}{2}  = 2 \frac{4}{8}
The we can easily add up these fractions
2 \frac{1}{8}  + 3 \frac{4}{8}  + 2 \frac{4}{8}  = 8 \frac{1}{8}
The correct answer is D. 8 1/8 ft

A rectangular pool contains 920 cubic meters of water. the pool is .4 meter deep and 100 meters wide. How long is the pool?
LekaFEV [45]
Hi there,

Sol:
Length of the swimming pool = 260 m
Breadth of the swimming pool = 140 m

Let the height of the water in the swimming pool after pouring water be h meters.

Volume of the water poured = 54600 m3

l x b x h = 54600
260 x 140 x h = 54600
h = (54600) / (260 x 140)
h = 1.5 m = 150 cm

Hope it helps

Find the length of the arc.
Arte-miy333 [17]
  • radius=r=7in
  • Angle=135°

We know

  • Length if arc=L

\boxed{\sf L=\dfrac{\theta}{360}\times 2πr}

\\ \sf\longmapsto L=\dfrac{135}{360}\times2π(7)

\\ \sf\longmapsto L=\dfrac{27}{72}\times 14π

\\ \sf\longmapsto L=\dfrac{27}{36}\times 14π

\\ \sf\longmapsto L=\dfrac{9}{12}\times 7π

\\ \sf\longmapsto L=\dfrac{63π}{12}

\\ \sf\longmapsto L=\dfrac{21π}{4}in
