Answer:
four million
Step-by-step explanation:
just subtract 12 million by 8 million
Set up a proportion.
27% = 0.27
81/0.27 = x/1
Multiply 1 to both sides:
x = (81 * 1)/0.27
Multiply:
x = 81/0.27
Divide:
x = 300
So they hope to sell 300 magazine subscriptions.
Write equations for both companies:
Company A = 80 + 0.30x
Company B = 20 + 0.50x
X = number of miles.
Set the equations to equal and solve for x:
80 + 0.30x = 20 + 0.50x
Subtract 0.30x from both sides:
80 = 20 + 0.20x
Subtract 20 from both sides:
60 = 0.20x
Divide both sides by 0.20:
x = 60 / 0.20
x = 300
The answer is 300 miles.
Draw the line OB. It's another radius of the circle, just like OC, so it's 17. Now look at DB. It's 15, because a radius that's perpendicular to a chord bisects the chord. So we have the triangle ODB. It's a right triangle. The hypotenuse is 17, one leg is 15, and we have to find the other leg.
Dr. Pythagoras tells us exactly how. (One leg squared) + (the other leg squared) = (the hypotenuse squared). It's really tough trying to type math here on my phone, so I'll let you go ahead and finish up the last step.
