Answer:
r=0.079577a or a/4![\pi](https://tex.z-dn.net/?f=%5Cpi)
Step-by-step explanation:
a=(4)(3.141593)r
Step 1: Flip the equation.
12.566371r=a
Step 2: Divide both sides by 12.566371.
<u>12.566371r</u>
12.566371
=
<u>a</u>
12.566371
= 0.079577a
X=hourly pay
y=signing bonus/extra fee
c=total amount made/cost
If john makes $10 an hour plus a $20 bonus for each day then
10x+20=c
In most equations/situations the number without the variable is the flat fee/signing bonus.
Answer:
195 students
Step-by-step explanation:
585/9=65
65*3=195
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
(-10,5)....x1 = -10 and y1 = 5
(-8,-3)....x2 = -8 and y2 = -3
now sub
d = sqrt ((-8 - (-10)^2 + (-3 - 5)^2)
d = sqrt ((-8 + 10)^2 + (-8^2)
d = sqrt (2^2) + (-8^2)
d = sqrt (4 + 64)
d = sqrt 68
d = 8.25 <====
greg score = x
kara score = 3/4x-1
x + 3/4x-1 = 153
1 3/4x -1 = 153
1 3/4x = 154
x = 154 / 1 3/4 = 88
gregs score was 88
kara s score was 153 -88 = 65
