You have to simplify the first equation until you get x= something.
The fill that in the x spot in the second equation.
Answer: 117.226666667 cm^3
Step-by-step explanation:
So, we all know the formula for working out the volume of a cone is
V= 1/3πr^2h
V = 1÷3 x 3.14 × r^2 x h
The radius is half the diameter. Your diameter is 8 so the radius would be 4. And 7 is your height by the way.
So let's plot it all in!
V= 1÷3 x 3.14 × 4^2 x 7
V = 117.226666667cm^3
Round to the nearest 10 = 117.2cm^3
To the nearest 100 = 117.23cm^3
To the nearest whole number = 117cm^3
6 persons * $8= $48
4 popcorns * $6.25= $25
6 persons * $2.75= $16.5 (drinks)
$48+$25+$16.5= $89.50 total
Answer:
(1,-2) for the last time
Step-by-step explanation:
Substitute the values and cancel the common factor in the equation
Answer:
87.5%
Step-by-step explanation:
It decreased by 16 - 2 or 14, and since he wrote 16 tickets last week, the answer is 14/16 in percent form, or 7/8 = 87.5%.
