Point slope form: y-y-coordinate=slope(x-x-coordinate)
slope intercept form: y=mx+b
standard form: x + y=

Isha, a super excited Khan Academy user, has increased

HACTEHA [7]

Answer: 8000 points last week.

Step-by-step explanation:

If she has increased by 75% in a week to get 14000 points then we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.

175% * x = 14000

1.75x =14000 Divide both sides by 1.75

x= 8000

So she had 8000 points last week.

Check:

175% * 8000= 14000

1.75 * 8000 = 14000

14000 = 14000

Use the arc length formula and the given information to find r. Show your work for full credit. s = 8.1 ft θ = (3.14/3)rad r = ?

VladimirAG [237]

This question is simple I'm a little confused on the specifics so I will try my best to help.

s=θ(r)
arc length = angle x radius
2.46888m(or 8.1 ft) = (π/3) x r
$r = (\pi /3)/2.46888$
$r = .425m$

How do you know when ratios are equivalent and when they are not equivalent

White raven [17]

Ratios are equivalent when that can be reduced or multiplied to be the same number.
Ex) 1:4 is the same as 2:8 or 4:16
10:20 is the same as 8:16 or 1:2

They are not equivalent if you can’t do this
