Answer:
Step-by-step explanation:
You don't need to memorize all of the square roots. Looking at each square root, find a number close to it that you know -- The square root of five is close to the square root of four, which is 2. The square root of 28 is close to the square root of 25, which is 5. 28 is a slightly bigger than 25, so the square root will be slightly greater than 5.

Answer:
divide this amount ($88.26875) by the number of people
Step-by-step explanation:
6.75% of $72.50 is 4.89375
15% of $72.50 is 10.875
72.50 + 4.89375 + 10.875 = 88.26875
divide this amount (88.26875) by the number of people
Answer: The goal was $500
======================================================
Work Shown:
x% = x/100
175% = 175/100 = 1.75
Let g be the goal, which is the amount of money the club wanted to raise
175% of goal = 175% of g = 1.75g
The expression 1.75g represents how much money was actually raised, which was $875. Set the two expressions equal to each other. Solve for g
1.75g = 875
g = 875/1.75 ....... divide both sides by 1.75
g = 500
The club's goal was to raise $500
Note how 75% of $500 is 0.75*500 = 375
When they raised 175% of the goal, this means they went 75% overboard and added on 375 additional dollars (on top of the 500 they wanted). So they got to 500+375 = 875 which lines up with the instructions. This helps verify the answer.
Or we can see that 1.75*g = 1.75*500 = 875 which helps confirm the answer as well.
We are given rule
when
input is (x,y)
then output is (x+7 , y-3)
(A)
we are given
input is (-10,0)
so, x=-10 and y=0
now, we can find output
x+7=-10+7=-3
y-3=0-3=-3
so, output is (-3,-3)
(B)
we are given
input is (-7,3)
so, x=-7 and y=3
now, we can find output
x+7=-7+7=0
y-3=3-3=0
so, output is (0,0)
(C)
We know that
x+7 and y-3 are translation rules of function
so, this is function
