Answer:
=21+11x
Step-by-step explanation:
The answer is 75! Explanation, use the distance formula
suppose 4:4:7 be 4x, 4x, 7x
or, 15x = 180°
or, X = 180/15
or, X = 12
therefore,
4x = 4x12= 48
4x= 4x12= 48
7x= 7x12= 84
so if you plus all of them you get 180
The center of the circle is expressed as (h,k) in the standard form of equation. In this case, the diameter endpoints are <span>(-3, 8) and (7, 4). Hence the circle center has coordinates which are the midpoints of the two points.
x = (-3 + 7) /2 = 2
y = (8 + 4) /2 = 6
hence the center of the circle is (2,6)</span>
Answer:
100 boards
Step-by-step explanation:
Step one:
Given data
We are told that Cynthia was paid 20 cents per board for painting the fence
that is for 1 board painted she gets $0.2
If she was paid $10
let us find the number of boards she painted for $10
= 10/0.2
=50 boards
This means that the total boards were 50*2= 100 boards
