Answer:
Step-by-step explanation:
Difference = New temperature - original temperature
= -12 - (18)
= - 30
New temperature is 30° less than the original temperature
.2
When you do 64/80 you get 0.8 which means that the percent decrease is .2
no they are not equivalent
0.4/15 = 0.026
so for every minute they travel 0.026km
0.6/20 = 0.03
so for every minute they travel 0.03km
so they are not the same/equivalent
150.72
3² × 3.14 × 6 - 1² × 3.14 × 6 = (3² - 1²) × 3.14 × 6 = 150.72
