Answer:
The percent change in Nancy height is 10%
Step-by-step explanation:
Given : when Nancy started middle school, she was 60 inches tall. when she started high school, she was 66 inches tall.
We have to find the percent change in her height.
Percentage change is given by the ratio of the difference in old value and new value to the old value times 100
Mathematically written as

For the given data,
Old value = 60 inches
New value = 66 inches
Thus, the Percentage change is given as,

Simlify, we have,

Thus, The percent change in her height is 10%
There are several process for finding the HCF or Highest Common factor for any numbers given. In this case the two numbers given are 240 and 1500.
Firstly we need to divide 1500 by 240 and check if there are any remainders. On dividing we get quotient is 6 and remainder is 60. Now again we have to divide 240 by 60 which we found as remainder previously. Then on dividing 240 by 60 we get no remainder. So the 60 is the HCF or the Highest Common Factor of 240 and 1500. This is the easiest process by which the HCF of any set of numbers can be found.
FOIL is an ancronym to help you remember to multiply each term. basically it's for people who can't distribute good
anwya
FOIL stands tells you which terms to mulitply, you then add the results up
F=First terms
O=Outer terms
I=Inner terms
L=Last terms
so
(x-2)(x-3)
First: x times x = 
Outer: x times -3=-3x
Inner: -2 times x=-2x
Last: -2 times -3=6
now add them all up

answer is the second option
Answer:
C) 15.92
Step-by-step explanation:
This is a right triangle, so we can use trig functions
tan theta = opp/ adj
tan 53 = x/12
12 tan 53 =x
15.92453786 =x
