20 hours times $9 is $180. She would have to work over 20 hours to earn more than $180.
I would say 21 hours.
Answer:
The product of the two numbers is 832
Step-by-step explanation:
x+y= 58
x-y=6
2x = 64
x = 32
y = 26
32*26=832
When you expand the binomial, you isolate each of the parts.
So, (x-y)^4 would turn into...
x^4 - y^4
The powers stay the same because (outside the parenthesis) you multiply them with whatever is inside the parenthesis. In this case, would be 1. All variables and numbers without a listed power have a power of one. Multiply 4*1 to get 4.
Equilateral: 3
scalene: 5
isosceles: 1, 2, 4
Step-by-step explanation:
"markup" contains "up". so, the price goes "up". this is actually increasing the price (e.g. by calculating the profit margin of selling an item on top of the cost of buying the item from the manufacturer).
"markdown" contains "down". so, the price goes "down". e.g. with discounts.
here we have a markup. it is 150%.
that means the price goes up by 150% compared to the original cost.
so, the computer game costs in the store
the original cost + 1.5× original costs
25 + 1.5×25 = 2.5×25 = $62.50
