The length the hypotenuse of an isosceles right triangle, or a 45-45-90 triangle, is always radical two times as long as any leg of the triangle. With this, we can set up an equation where x represents the length of a leg.
x

= 8

divide both sides by
x = 8
The length of a leg of the triangle is 8
Answer:
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.
Step-by-step explanation:
Lin runs 5 laps around a track in 10 minutes.
i.e. 5 laps in 10 minutes.
so
5/10 = 1/2 laps per minute
- unit rate = 0.5 laps / per minute
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
Unit rate = 0.5 laps per minute
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.
Answer:
Option (c) is correct.
Step-by-step explanation:
Given equation is :

The equation can be solved for a as follows :
Step 1.
Cross multiply the given equation

Step 2.
Now subtract b on both sides
3s-b = a+b+c-b
3s-b = a+c
Step 3.
Subtract c on both sides
3s-b-c=a+c-c
⇒ a=3s-b-c
The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".
