Answer:
simple its 48
Step-by-step explanation:
i just know XD
We know that the entire angle is equal to 90 degrees (look at image below). This means that the sum of 4x-10 and x is 90 degrees, so you can make a formula:
4x - 10 + x = 90
Now you can solve for x
5x - 10 = 90
5x = 100
x = 20
Hope this helped!
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: what are we putting from least to greatest
Step-by-step explanation:
3 is to 5 as x is to 20
5 goes into 20 4 times so 3(4) gives you x
and x=12
