Answer:
<em>Option </em><em>3</em>
Step-by-step explanation:
Rewriting input as fractions if necessary:
3/8, 3/20
For the denominators (8, 20) the least common multiple (LCM) is 40.
LCM(8, 20)
Therefore, the least common denominator (LCD) is 40.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
3/8 = 3/8 × 5/5 = 15/40
3/20 = 3/20 × 2/2 = 6/40
Area= length*width
Plug in what you know.
144= 24*width
Divide both sides by 24.
width= 6 meters.

Answer:
S varies partly directly as M and Q.
S=C.
S=KMQ+C.
For the first one...
speed=80,m=220,Q=30.
80=K20×30+C.
80=600K+C......(I).equation one.
For the second one....
speed=60,m=300,Q=40.
60=K300×40+C.
60=12000K+C.....(ii). equation two.
Minus eqtn(I) from eqtn(ii).
80=600K+C.
- 60=12000K+C.
K=0.01754~0.018.
Substitute K=0.018 into eqtn(I).
80=600K+C
80=600×0.018+C.
80=10.8+C.
C=80-10.8=69.2.
The relation is S=0.018MQ+69.2
when speed is 100 and mass is 250 find the volume.
100=0.018×250×Q+69.2.
100=4.5Q+69.2.
4.5Q=100-69.2
4.5Q=30.8.
Q=30.8/4.5.
Q=6.8~7litres.
