What percent of 151 is 109? what percent of 151 is 109?

Answer

109/151 x 100% = 72.2%

Step-by-step explanation:

It is easier to understand this if written the other way around.

What percent is 109 out of 151?

Like " My mark was 20 out of 28 for the test. What percent is that?"

When you divide 109/151 the answer is already in decimal form.

109/151 = 0.722 which means the same as 72.2/100

NOte that this is already written as a percent (it is out of 100)

Let's change the format, without changing the value.

109/151 x 100% = 72.2%

× 100% is the same as x1

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
