Answer:
Step-by-step explanation:
s is the length of each side of the cube
volume = s³
343 = s³
s = ∛343 = 7 mm
Tes, because acceleration is how fast it is speeding up, the average speed isn't being given because tornados don't last more than a few miles, and instantaneous speed gives current velocity in a certain direction at a certain time, therefore it would be anytime, including 3 minutes ago, meaning velocity, the current speed, is correct.
Answer:
= 177.66
Step-by-step explanation:
you add all the pounds gained by group A in the 3 weeks which is 59.22 and then you multiply by 3 to give you 177.66
First convert the feet to inches:
3 feet= 36 in.; 4 feet=48 in.
Make an equation for each one:
Type A: h=36+15x
Type B: h=48+10x
Since the questions wants the heights to be equal, h=h so you can substitute so you have:
36+15x=48+10x
5x=12
x=2 2/5 years or 2.4 years

Answer:
a. 0.6 h
b. 1.3 h
c. C -- No
d. 4.2 mi/h
Step-by-step explanation:
a. The relationship between time (t), speed (s), and distance (d) is ...
t = d/s
The time spent running 4 miles at 7 miles per hour is ...
t = (4 mi)/(7 mi/h) = (4/7) h ≈ 0.6 h
__
b. The time spent walking home is ...
t = (4 mi)/(3 mi/h) = 4/3 h ≈ 1.3 h
__
c. C -- No, less time is spent at 7 mi/h
__
d. The average speed is ...
s = d/t = (4 mi +4 mi)/(4/7 h +4/3 h) = (8 mi)/(40/21 h) = 4.2 mi/h
