If the measure of a central angle is 28°, then to find the measure of its arc, you would need to do which of the following?
Answers
To find the measure of arc, there would be need of radius.
What is angle?
An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Given that,
The measure of central angle is 28°.
Since, the formula to find arc is
arc = angle x radius
Therefore, to find the arc, radius would be needed.

(3/10) - (1/5) = (1/10)
Explanation:
Make sure both fractions have the same denominator. 1/5 would turn into 2/10, and 3/10 would stay the same. When the denominators are equal, subtract the numerators to get the answer.
1/5 = 2/10
(3/10) - (2/10) = (1/10)

Why?
Well because when rounding first we see what number we need to round. In this case it is 14.36 (3), next we look at the next number after the number which we need to round from which is 14..36 (6). If this number is 5 or MORE then we will round to the next number. But if it is LESS than 5 then we will keep it that number and add a 0 at the end. Since this number is AFTER 5 it will round up to 14.40.
So, 14.36 rounded to the nearest tenth is 14.40.

Answer:
1)For, m = 3/4 , (0,4) , 4y - 16 - 3x = 0 is the equation of line.
2)For, m = 4 , (-2,-5) , y - 4x - 4 = 0 is the equation of line.
3)For, m = -1/3 , (4,-1) , x + 3y -1 = 0 is the equation of line.
Step-by-step explanation:
If m is the slope and (x0,y0) is the point on any given equation, then
by POINT SLOPE FORMULA:
The line equation is given as (y - y0) = m (x -x0)
Now , here:
1) m = 3/4 , (x0, y0) = (0.4)
So,, the equation of line is
on simplification, 4y - 16 - 3x = 0 is the equation of line.
2) m = 4 , (x0, y0) = (-2.-5)
So,, the equation of line is
on simplification, y - 4x - 4 = 0 is the equation of line.
3) m = -1/3 , (x0, y0) = (4, -1)
So,, the equation of line is
on simplification, x + 3y -1 = 0 is the equation of line.

Leah wears less makeup than Tanya which is why the ratio of the makeup she wears to Tanya is 0.625 : 1.
In finding the ratio of the amount of eye makeup Leah wears to the one that Tanya wears, you have to first assume that Tanya wears 1 unit of makeup.
Leah wears 5/8 of this amount which means that Leah wears 5/8 makeup.
The ratio will be:
Amount of makeup Leah wears : Amount Tanya wears
5/8 : 1
0.625 : 1
In conclusion, the ratio of makeup won by Leah to that won by Tanya is 0.625 : 1.

If Tanya wore 1 tub of makeup, Leah would wear 5/8 of a tub of makeup, so:
LEAH vs TANYA:
5/8 : 1
multiply both sides by 8 to get rid of fractions:
5 : 8
