Use the Pythagorean theorem:
x = √(12^2 + 9^2)
x = √(144 + 81)
x = √225
x = 15
1:5
Steps:
1. Add all the numbers
2. Take Derek’s number of votes and turn step 1’s answer and Derek’s number of votes into a ration:
3. You will now have 36:180
4. Simplify by a number they both share (36).
5. Your new simplified answer would be 1:5.
25 x² - 10 x = 0
5 x ( 5 x - 2 ) = 0
x = 0 and
5 x - 2 = 0
5 x = 2
x = 2: 5
x = 2/5
Answer: B ) x = 0 and x = 2/5
Answer:
he makes $112.50
Step-by-step explanation:
first you have to find out how much he makes before tax is taken out. all you do is multiply 12.50 by 30, which gives you $375.00. then, you can either put in the calculator 30%375 or 0.3×375(both are the same thing) and you should get $112.50
