Ok so ratios
height:shadow =60:24
fractionify
60/24=5/2
5:2 is ratio
if shadow of tree=4 then what is height
5:2=x:4
multipliby 2
10:4=x:4
x=10
10 feet
Yes, they are.
You're not changing anything fundamental about them. They're just flipped expressions.
Answer:
75 ≥ t
Step-by-step explanation:
Velocity * time = distance
40 (miles / hour) * t (hours) = 60 (miles)
Take note how the units work. miles/hour * hours = miles. This is an indication that a formula we picked is correct.
Now, looking at our formula (and neglecting units at this point)
40t = 60
t = 60/40
<span>t = 1.5 hours</span>
