To solve this, we just have to subtract the numbers.
That's our solution set.
Have a nice day! :)
Answer:
The sum of two angles is 360 degrees.
Step-by-step explanation:
Answer:
$429.75
Step-by-step explanation:
First, find the tax rate on the sale of the boat: Let r represent that rate. Then,
$12,500r = $562.50. Solving for r, we get r = $562.50 / $12,500 = 0.045
The tax rate is 0.045, or 4.5%.
Applying this tax rate to a boat selling for $9,550:
0.045($9,550) = $429.75. This is the amount of tax on the 2nd boat.
If we call the leg of the small triangle y, and the leg perpendicular to x z, we can apply Pythagoras 3 times:
(1) 4 + y^2 = x^2
(2) x^2 + z^2 = 196 => z^2 = 196-x^2
(3) y^2 + 144 = z^2 => y^2 = z^2 - 144
Now fill in (3) in (1):
4 + z^2 - 144 = x^2
and then (2) in (1):
196-x^2-140 = x^2 => 2x^2 = 56 => x = √28 = 2√7
Answer C!
