Answer:
152 cups were ordered.
Step-by-step explanation:
Let the number of small size cups = x
And the number of medium size cups = y
Total number of cups used = 63
Therefore, first equation will be,
x + y = 63 -------(1)
Brewers emptied = 147 oz
Quantity of coffee in a small cup = 8 oz
Total amount of coffee in small cups = 8x
Quantity of coffee in a medium cup = 12 oz
Total amount of coffee in medium cups = 12y
Therefore, second equation will be,
8x + 12y = 147 -------(2)
Multiply equation (1) with 12 and subtract is from equation (2)
(8x + 12y) - (12x + 12y) = 147 - 756
-4x = -609
x = 152.25
Therefore, 152 cups of small size coffee were ordered.
Answer:
y = (-5/2)x + 1
Step-by-step explanation:
y = (-5/2)x + c
When x = 2, y = -4
-4 = (-5/2)(2) + c
-4 = -5 + c
c = -4 + 5 = 1
y = (-5/2)x + 1
Answer:
207.24 or 66pi
Step-by-step explanation:
The combined area of the bases = 2 * 3^2 * pi = 18 pi
The area of the side is 3*2*8*pi = 48 pi
48 pi + 18 pi = 66 pi
66 * 3.14 = 207.24
Answer:
2.73
Step-by-step explanation:
You could use a calculator if your teacher/instructor lets you! :)
OR you could do long division.
So you know that 3^4 is your numerator and that is (4)(4)(4)(4)=81
3^2 is your denominator and that is (3)(3)=9
81/9
=9
