Answer:
It decreased
Step-by-step explanation:
It decreased. Assuming that the temperature is 100 and it is now reduced by 60% then the temperature will be at 40 and if it increased by 80% then the final temp is 72. So it is 48% of the original temp.
Answer:
7.142m/s
Step-by-step explanation:
Velocity=change is distance/change in time
change in distance=400m-0m=400m
change in time=56-0=56seconds
v=400m/56s
v=7.143m/s

Step-by-step explanation:
Answer:
2 years
Step-by-step explanation:
Simple interest is calculated using the formula: I = prt, where I = the amount of interest earned, p = principal amount, r = rate and t = time. In this case, you know the principal = $2000, the rate = 1.5% or 0.015 and the I = $60, so you are solving for time 't':
I = prt or $60 = $2000(0.015)t
Simplify: 60 = 30t
Divide both sides by 30: 60/30 = 30t/30 or t = 2 years.
The answer is AB= 52, because x=15
