Answer:
c = 1.20s + 3.00
Step-by-step explanation:
1.20 times the sum, s, is written as 1.20s. Adding 3.00 to that gives ...
c = 1.20s + 3.00
__
The sum is ...
s = L +W +H
so the equation could be written ...
c = 1.20(L +W +H) +3.00
The wording of the question suggests the independent variable should be s.
Answer:
b = 3/4
Step-by-step explanation:
Using point slope: y - y1 = m(x - x1).
Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.
0.2 = 1/5, so 1/5 * 1/4 = 1/20
Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → <em>3/4</em>
Answer:
480
Step-by-step explanation:
Let h represent the number of high-quality downloads. Then the total download size is ...
4.1h +2.7(1130-h) = 3723
1.4h = 672 . . . . . . . . . . . . . . subtract 2.7·1130 = 3051
h = 480 . . . . . . . divide by 1.4
There were 480 downloads of the high-quality version.
