Answer:
1.7
Step-by-step explanation:
( 5x + 2y = 7 ) 2
( - 2x + 6y = 9 ) 5
10x + 4y = 14
-10x + 30y = 45
----------------------
34y = 59
y = 1.7
We put cubic feet of water used on the x-axis and the cost on the y-axis.
The graph will start at (0 , 12.7) because this is the fees before using any water.
The slope of the graph from 0 < x < 300 will be $0.039/cubic ft, and this interval will start at (0 , 12.7) and end at (300 , 24.4).
The slope of the graph for x > 300 will be $0.052/cubic ft, and this interval will start at (300 , 24.4) and continue to x value infinity.
220 units lies within the interval 0 < x < 300 so we use the first slope.
y = 0.039(220) + 12.57
= $21.15
We break 675 cubic feet into two parts, 300 + 375 cubic feet as they will be charged differently.
The cost of the first 300 cubic feet = $24.40
The cost of the remaining 375 cubic feet = 0.052 x 375 = $19.50
Total cost of 675 cubic feet = $43.90
Answer:
8km
Step-by-step explanation:
1:100,000 = 1.6 miles = 1 kilometer x 8 = 8 km
Answer S−2BP=h
Explanation:isolate the Phterm on one side of the equation:S−2B=PhDivide both sides by P:S−2BP=h
Hopefully this helps!
brainlest if it rightt
HIS walking rate was 1 mile per hour because 20min times 3 is 1 hour, and 1/3 times 3 is 1 mile thus 1mph if can plz mark brainliest
