I know the answer but first I need you to answer my math question
Gosh I hope you didn't have to turn this in yet. I'll help you with 4 and 5.
If you want to find the unit rate, you're finding out how much money it is per ounce.
Divide your cost by the number of ounces.
So for example, 3.98 / 16.
After you get your answers, write them down. Whichever answer is the lower number is the better buy because each ounce costs less.
12m; if one side is 9m then that means 42 - 9 - 9 would yield the size of the two remaining sides together. 42-18=24 24 divided between the two sides left means each remaining side had to be 12m
Answer:
x = 7 , y = 7
Step-by-step explanation:
A 45- 45- 90 triangle is an isosceles right triangle with the 2 legs being congruent , that is
x = 7
Using Pythagoras' identity in the right triangle, then
y² = 7² + 7² = 49 + 49 = 98 ( take square root of both sides )
y = 
= 
= 
× = 7
