To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.
45-32 = 13 / 32 *100= 40.625 round to the nearest percent is 41%
Answer:
24
Step-by-step explanation:
First we must recognize that this equation is a quadratic function, therefore we can use the quadratic equation and look only at the discriminate portion of that formula. However, before doing so we need to set up our equation by taking the 1 to the other side and so:
And we know that in general a quadratic function is such that:
And so our quadratic equation is:
But we only need to look at what's under the square root meaning:
This is our discriminant and since a=5, b=2 and c=-1 we have:
Answer:ITS 465
Step-by-step explanation:
4 + 6 + 5 = 15
AND THE DIFFERENCE IS 2 BETWEEN 6 AND 4
Answer:
Step-by-step explanation:
<u>Factoring the given numbers:</u>
- 20 = 2*2*5
- 25 = 5*5
- 85 = 5*17
CGF(20,25,85) = 5
<u>The sum of given numbers:</u>
- 20 + 25 + 85 =
- 5*4 + 5*5 + 5*17 =
- 5*(4 + 5 + 17) =
- 5*26 =
- 130
Answer:
Step-by-step explanation: That is a 90 degree angle. Using L is an example of a 90 degree angle, or a right angle, which is its common name.
