Answer:
(4,-9)
Step-by-step explanation:
It takes 40 minutes more going up or 40/60 = 0.67 hours
more.
Let us say that:
t = the time required for him running down
t + 0.67 = time required for him running up
Since the distance of running up and down must be equal
therefore:
(3 miles / hr) * (t + 0.67) = (5 miles / h) * t
3 t + 2.01 = 5 t
2 t = 2.01
t = 1.005 hr
So the total length of the hike is:
length = 2 * (5 miles / hr) * (1.005 hr)
<span>length = 10.05 miles</span>
First you have to simplify whats in the parentheses:
22 + (-10)
= 22 - 10
= 12
Answer:
59200 I think
Step-by-step explanation:
In ΔRTS ⇒⇒⇒ RT = 8 , RS = 3 and ST = 5.4
In ΔRVU ⇒⇒⇒ RV = 4 , RU = 1.5 and UV = 2.7
We can conclude the following:
⇒ RT/RV = 8/4 = 2 →(1)
and ⇒ RS/RU = 3/1.5 = 2 →(2)
and ⇒ ST/UV = 5.4/2.7 = 2 →(3)
From (1), (2) and (3)
∴ Δ RTS is similar to ΔRVU by PPP
SO, the best statement is:
Each pair of sides corresponds with a common ratio of 2.
