The correct answer is B. y + 1 = -1/5 (x + 2)
I got B by putting the numbers in point-slope form which is y - y1 = m ( x - x1 ) so I got: y + 1 = m ( x + 2 )
Then to find m(the slope) I knew if the slope was 5 it would be parallel to y=5x+3 so therefore -1/5 would be perpendicular to the line y=5x=3.
Hope that helps!!
<span>a. Calculate the slope for this drain pipe.
1/22
b. A rainwater pipe 30 feet long must run under the edge of a roof. What is the minimum vertical distance the pipe must drop between its ends?
Turn 30 feet to inches so 30 * 12 = 360 inches
Now times 1/22 x 360 = 16.32 inches . If they want it in feet just change 16.32 to feet by dividing 16.32 / 12
c. A design calls for a drainage pipe to cross a building 45 feet wide as it drops 25 inches. Is this pip steep enough to function properly? Explain.
Change 45 feet to inches so 45 * 12 = 540
Now times 540 * 1/22 = 24.54 inches so 25 inches would be steep enough since it droops 25 inches. </span>
Answer:
right triangles
always
Step-by-step explanation:
Similar triangles are obtained by rise/run
Since the ratio for all triangles are the same, they have the same slope.
5.50=0.10d+0.05n
70=d+n
how to solve-
n=70-d
5.50=0.10d+0.05(70-d)
5.50 = 0.10d +3.5 -0.05d
5.50= 0.05d+3.5
2=0.05d
d=40
70=d+n
70=40+n
n=30
there are 40 dimes and 30 nickels
