Answer:
Hannah got $200 for her mom
Step-by-step explanation:
With the numbers in this question you don't even have to worry about percentages.
You can think of it in quarters:
75% is 3 quarters of 100%
(25% + 25% + 25% + 25%)
$150 is 3 quarters of $200
($50 + $50 + $50 + $50)
Hope this helps and isn't a confusing way of explaining it! :)
Answer:
I like saying rise over run because it helps me remember that rise means how many units you move up or down from point to point which on a graph would be a change in the y values. Also that run means how far left or right you move from point to point which on the graph would mean a change of x values.
V of cylinder = πr²h
h=V /(πr²)
h=27/π -exact value
h=1323/(3.14*(7)²)= 8.6 cm - approximate value
Y= 70° because the values in a triangle must equal 180 so,
60+50= 110
180-110= 70
and since x in this equation is the same as y, by default,
x= 70°
