Answer:
$7.50
Step-by-step explanation:
3/4's of 60 is 15 and half of 15 is 7.50
Answer:
5) 9
6) 11 2/3
Step-by-step explanation:
Use the Pythagorean Theorem.
5) a²+5.6²=10.6²
a²+31.36=112.36
a²=81
a=√81
a=9
6) a²+4²=12.3333²
a²+16=152.11111
a²=152.11111-16
a²=136.1111
a=√136.1111=11.6666
Exponents can make the problem smaller and look less confusing. If you see a problem with 5*5*5*5*5*5*5*5 then you're going to eventually loose count and will have to keep repeating. But if you put 5 to the 8th power then you know right away just to multiply 5, (8) times,
You bought 5 books for $60 and 2 movies for $30
160/32= 5
5*5= 25 mm
25 mm <em>is how many millimeters represents the kilometers.
</em>
I hope this helps!
