Answer:
6
Step-by-step explanation:
Profit is revenue minus cost.
P(x) = R(x) − C(x)
P(x) = 28x − (7x + 117)
P(x) = 21x − 117
When the profit is 0, the value of x is:
0 = 21x − 117
21x = 117
x = 5.6
Rounding up to the nearest integer, the company starts to turn a profit at 6 milkshakes.
Answer:
The top box in the middle, should be 15.
The bottom box on the left should be 1.5
2x - 3 = 11
2x = 14
x = 7
Using this value, The answers would be the following:
A. 23/21 (assuming you are dividing 2 by 3x; if you multiplied 2/3 by x, the answer would then be 17/3)
B. 21/2
Answer:
9
Step-by-step explanation:
Given that:
Dimension of Original photo = 4 inches by 6 inches
Intended dimension of model = 3 feet by 4 1/2 feets
Converting from feets to inches :
1 foot = 12 inches
Therefore,
Intended dimension of model :
3 feets = (3 * 12) = 36 inches
by 4 1/2 feets = (4 1/2 * 12) = 54 inches
Hence, scale factor required :
36 /4 = 9
54 / 6 = 9
Scake factor = 9
