The distance formula is used to find the distance between two points in the coordinate plane. The point that is at the same distance from two points A and B on a line is called the midpoint. You calculate the midpoint using the midpoint formula.
Answer:
36 minutes
Step-by-step explanation:
We can write a ratio
2 laps 9 laps
------------- = --------------
8 minutes x minutes
Using cross products
2x = 8*9
2x = 72
Divide by 2
2x/2 = 72/2
x = 36 minutes
Answer:
5%
Step-by-step explanation:
to work out what percent 17 is out of 340 we can formulate an equation
so 340(x%)=17
when we solve for x we get 5
X=4. If k is the midpoint then JK is equal to KL. Since JK is 7 then KL is also 7 meaning JK is 14. JK is represented by the expression 4x-2 so you just set that expression equal to 14 and solve for x. Hope this helped!
