Answer:
A) 18.3
Step-by-step explanation:
Since adding b and a gives 19.
c must be less than 19.
So, A) 18.3 is the correct answer
1. Eyeballing the data, the best fit will be pretty close to a line between the leftmost point and the rightmost point.
We estimate those points as (4,220) and (28,470)
The point point form for a line joining (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
(28 - 4)(y - 220) = (470 - 220)(x - 4)
24(y - 220) = 250(x-4)
24y - 5280 = 250x - 1000
24y = 250 x + 4280
y = (250/24) x+ (4280/24)
Approximately that's,
y = 10.4 x + 178
Answer: 4th choice, 10.4x + 180
2. For 48 wheelbarrows,
y = 10.4(48)+180 = 679.2
Answer: 679.2 liters of sand
Answer:16.110
Step-by-step explanation:
Answer:
zero slope
Step-by-step explanation:
Given:
Rectangular room is 10 feet; and
1 x 1 ft tiles
The expression for this problem would be:
If we know that the width is w, while the length is w + 10,
therefore the perimeter is 2w + 2 (w + 10), so you need 4w + 20 - 4, or 4w + 16
tiles. Since you do not want to count the corners, twice.
