Answer:The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0
a=5, b=2, c=-4, x0=15, y0=-21
Step-by-step explanation:
R/2-6=14
r/2=20
r=40
The answer is 40
53: 800 and 900
54: 700 and 800
55: 500 and 600
56: 2,771,100 and 2,771,200
57: 90,120,000 and 90,120,100
58: 631,900 and 632,000
59: 93,300 and 93,400
60: 200 and 300
61: 900 and 1000
62: 39,576,700 and 39,576,800
63: 24,900 and 25,000
64: 471,100 and 471,200
A volleyball uniform costs $13 for the shirt, $11 for pants, and $8 for socks. Write two equivalent expressions for the total cost of 12 uniforms. Then find the cost.
Write an expression for the cost of 1 uniform, add $13, $11 and $8 .
$13+$11+$8
Write an expression for the cost of 12 uniforms, multiply 12 by the cost of 1 uniform.
12($13+$11+$8)
Simplify using the distributive property.
=12⋅13+12⋅11+12⋅8=156+132+96
Now Add.
=384
So, the total cost of 12 uniforms is $384 .
