slope = (y2-y1)/(x2-x1)
m =(17-4)/(8-1)
m = 13/7
You have to keep the pairs in the same order
If you would like to know 55 percent of what number is 495, you can calculate this using the following steps:
55% of what number = 495
55% * x = 495
55/100 * x = 495
x = 495 * 100/55
x = 900
The number you are looking for is 900.
72-54 =2a
A=9
A+54= 3a+b
63=3a+b
63= 3(9) +B
B=36
A+B =C
9+36=45
C=45
A+2C=4a+2D
9+ 2(45) = 4(9) + 2D
63=2D
D=31.5
A+D=F
9+31.5=F
F= 40.5
Answer:
33 m/s
Step-by-step explanation:
120 km/h × (1 h)/(3600 s) × (1000 m)/(1 km) ≈ 33 m/s

<em>Additional comment</em>
In general, units conversion is done by multiplying by a factor whose numerator and denominator have equal values, but different units. The units in that fraction need to be arranged to cancel the units you don't want and leave the units you do want.
The formula for volume of a cylinder is pi*r^2*h
So reversing that,
Volume/height/pi =
54/6/3.14 = <span>2.86624203822 or 2.9 </span>
