What percent if 33.5 is 21

Answers

Answer 1
Answer: To find percentage one number is of another, you divide the two, with the number that is a percentage as the numerator.
21/33.5 = 0.627
Now, you move the decimal point over to the right two places to form the percentage.
62.7%
21 is 62.7% of 33.5

What is the measure of arc GH??

Answers

Option C:

The measure of arc GH is 45°.

Solution:

Given data:

m∠GFH = 22.5°

To find the measure of arc GH:

By inscribed angle theorem,

The measure of an inscribed angle is equal to the half of the measure of the intercepted arc.

$m\angle GFH = (1)/(2)* m \ {(arc \  GH)}

$ 22.5^\circ= (1)/(2)* m \ {(arc \  GH)}

Multiply by 2 on both sides, we get

$ 2* 22.5^\circ=  2* (1)/(2)* m \ {(arc \  GH)}

$ 45^\circ=   m \ {(arc \  GH)}

Switch the sides.

m(arc GH) = 45°

The measure of arc GH is 45°.

Can someone help me with this? :)

Answers

C is the answer
Step by step explanation:
To get the answer you must expand the brackets (multiply the number or numbers outside the brackets with the ones within to remove them)
To do this you must first in 2(8+6) multiply 2 times 8 which is 16
Then you would multiply 2 times 6 which is 12
As the operation is a + that would mean the answer is 16+12
Hope this helps!
The answer is c! 16 + 12

How to find the average rate of change for f(x)=2^x;[2,4]​

Answers

Answer:

6

Step-by-step explanation:

The average rate of change over the interval [a,b] for a function f is (f(b)-f(a))/(b-a).

So the average rate of change for f(x)=2^x on [2,4] is:

(2^4-2^2)/(4-2)=(16-4)/(2)=(12)/(2)=6.
