Answer:

165

Step-by-step explanation:

5c^{2} -3d+15

c = 6 and d = 10

5c^{2} = 5 × 6² = 5 × 36 = 180

5c^{2} - ( 3 d ) = 180 - ( 3 × 10 ) = 180 - 30 = 150

5c^{2} -  3 d  ( + 15 ) = 150 + 15 = 165

Answer:

165

Step-by-step explanation:

Substitutet 6 for c and 10 for d in  5c^2 - 3d + 15​ .

Note that " ^ " is used here to denote exponentiation; c2 is meaningless.

Then we have 5(6)^2 - 3(10) + 15, or   180 - 30 + 15, or 165.

50 cases in 44 minutes equals how many cases in 60 minutes
Blizzard [7]
To solve this, set up a proportion, crossmultiply, and solve for x. 

Let x = the unknown amount of cases in 60 minutes.

\frac{50}{44} = \frac{x}{60}
44x = 50(60)
44x = 3000

Divide both sides by 44 to isolate variable x
x = 3000 / 44
x ≈ 68.1818 (the 18s repeat forever)

Rounding to the closest case and assuming the rate stays constant, you would get approximately 68 cases in 60 minutes. If you need not round to the nearest case, you would get approximately 68.18 cases in 60 minutes.
