First, find 20% of 5 hours. 20% is also 1/5 of something, and 1/5 of 5 is 1.
Multiply 5 by 3 for the 300%, getting 15 hours, and add 1 for the 20%.
He spent 16 hours on the project. Hope this helps!
The least common multiplier of 18 and 24 is 72. Because all of 18's multipliers do not match up with 24's multipliers until 72, it is the LCM
200/2 cause it's half so it equals 100, hope i helped
1000 divided by 100 is 10. 10 x 5 is 50. After the first year, Sue has 1050. But compound interest is interest on the amount AFTER the amount is added, so she will now earn interest on 1050. 1050 / 100 is 10.5. 10.5 x 52.50.
52.50 + 50 = 102.50. The answer is D. Hope this helps :)
4x^2-25= (2x)^2-5^2=(2x-5)(2x+5)
Used: a^2-b^2=(a+b)(a-b)
