Note angles not necessarily drawn to scale

kondaur [170]

Answer:

<h2>x = 90° - 30° = 60°</h2>

Step-by-step explanation:

Angles CGE and 30° are vertical angles.

Thus, Angle CGE is thus 30°.

Angle CGE and Angle x are complementary, so x = 90° - 30° = 60°

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

The volume of the cone is 294.38 cm the radius of the base is 7.5 cm which one of the following could be the height of the cone?

drek231 [11]

The volume of a cone is 1/3 pi*r^2 * h. Rearranging for height gives h = 3v / pi*r^2 = (3*294.38) / (3.14*7.5^2) = 5.00 (answer B)
