Answer:

D

Step-by-step explanation:

The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, that is

x = \frac{1}{2} (AB + DC )° = 0.5(51 + 79)° = 0.5 × 130° = 65° → D

150 is 100% of what number?
andriy [413]

Answer:

150 is 100% of 150

Steps to solve "150 is 100 percent of what number?"

We have, 100% × x = 150

or,

100

100

× x = 150

Multiplying both sides by 100 and dividing both sides by 100,

we have x = 150 ×

100

100

x = 150

If you are using a calculator, simply enter 150×100÷100, which will give you the answer.

Select the correct answer.
andrew-mc [135]

Answer:

v=\sqrt{\frac{E}{m}}

Step-by-step explanation:

The formula is given as:

E=mv^2

We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:

E=mv^2\\\frac{E}{m}=\frac{mv^2}{m}\\\frac{E}{m}=v^2

To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables:

\frac{E}{m}=v^2\\\sqrt{\frac{E}{m}}=\sqrt{v^2}\\\sqrt{\frac{E}{m}}=v

Putting v to left side (convention), we finally have:

v=\sqrt{\frac{E}{m}}
