Alberto ran a race at a speed of 9 meters per second. Omar had a 6 meter head start and ran at a speed of 7 meters per second. B

zloy xaker [14]

Answer: Alberto run 27 meters.

Time taken By Alberto=3 seconds

Step-by-step explanation:

Let d be the distance Alberto ran to catch Omar.

Then, distance ran by Omar=x-6

Also, $\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

Since, both started running at the same time.

Time taken By Alberto= $\frac{x}{9}$

Time taken By Omar= $\frac{x-6}{7}$

Now, at the point they meet time taken by both is equal.

$\frac{x}{9}=\frac{x-6}{7}\\\Rightarrow\ 7x=9(x-6)\\\Rightarrow7x=9x-54\\\Rightarrow9x-7x=54\\\Rightarrow\ 2x=54\\\Rightarrow\ x=27$

Hence, Alberto run 27 meters.

Time taken By Alberto= $\frac{27}{9}$ =3 seconds

Volume of a hemisphere formula?

Allisa [31]

To find the volume of a sphere you use...

V = 4/3 pi r^3

"Hemi-" means half. So we would divide by 2.

V= (4/3 pi r^3) / 2

Use the synthetic division to find the real zeros of f(x)=2x3 +7x2+2x-3

Dimas [21]

Answer:

$f(x) = {2x}^{3} + {7x}^{2} + 2x - 3 \\ f( \frac{1}{2} ) = 0 \\ f( - 3) = 0 \\ zeros \: = > 0 \: \: and \: \: - 3$

Step-by-step explanation:

$\frac{7\pi }{6}$ is an angle in the third quadrant

To find the reference angle subtract π from it

reference angle = $\frac{7\pi }{6}$ - π = $\frac{\pi }{6}$
