Answer:
C
Step-by-step explanation:
The volume of the cylinder that measures 6 ft tall and 3 ft wide and was triple would be 1,145.6 cubic feet. This is calculated using the formula volume =
(r²)(h). BUt before substitutign the value, we need first to multiply it byt 3 and for the wide it has to be further divided to 2 to have the radius, h = 18 and r = 4.5. Substituting the value it would give us 1,145.6
Answer:
11 pounds of deluxe, 35 pounds of regular
Step-by-step explanation:
If d is pounds of deluxe coffee, r is pounds of regular coffee, and C is the total cost, then:
d ≥ 11
d + r ≥ 46
C = 7d + 5r
Since deluxe costs more than regular, we want to use as little as possible to minimize the cost.
d = 11
r = 35
C = 252
Answer:
Step-by-step explanation:
Let's substitute the first equation into the second one.
- Multiply by and bring all the terms to one side.
I'll use my graphical calculator to solve this but you could factor:
(All rounded to 2 decimal places)
Now we can substitute these values into an equation for .
