Divide both the numerator and denominator by the highest number that can go into both.
26 divide 2 13
----- -----
30 divide 2 15
ans : 13/15 . Whatever is the highest number that can evenly go into both the top and bottom is the number you divide by until you cannot divide it
Answer:
7298.5 ft^3
Step-by-step explanation:
Volume of cone=pir^2h/3
=pi 29.516^28/3
=7298.5
Answer:
x=0, y=-2
Step-by-step explanation:
Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:
-7x + 9y = -18
-(4x + 9y = -18)
__________
-11x = 0
x = 0
Since we know x=0, then we plug it back into one of the equations to get the value of y:
-7x + 9y = -18
-7(0) + 9y = -18
0 + 9y = -18
9y = -18
y = -2
Therefore, x=0, and y=-2
Answer:
y = m x + b.23
Step-by-step explanation:
Part A: c for cost. c=0.31m+0.5
0.31m is the cost per minute. 0.5 is cost per call.
Part B: 0.31m+0.5=5.15 to solve we must rearrange.
subtract 0.5 from each side giving us 0.31m=4.85
divide by 0.31 giving us m=15.65
