Answer:
486kg
Step-by-step explanation:
density = mass / volume
2.7 = m / (100 x 60 x 30) **** Note the conversion to cm as the density is given in g/cm.
2.7 = m / 180000
m = 486000g
Now convert to mass in kg:
486000 g x 1 kg / 1000 g = 486kg
Answer:
do the following
Step-by-step explanation:
subtract the 2nd equation from the 1st....
x-2y = 14
-(x+ 3y = 9)
______________
-5y=5
y= -1
since you know that y is = to - 1 pick the 3rd answer
Answer:
yes
Step-by-step explanation:
Distance is the number of units between two points.
Tom's distance was 15 km shorter than James's
<h3>How to interpret the graphs</h3>
- From Tom's graph, the highest distance from home is 10 km
- From Jame's graph, the highest distance from home is 25 km
Calculate the difference between these distances

Evaluate the differences

Hence, Tom's distance was 15 km shorter than James's
