We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to
, and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to
ft

Answer:
A) 18
Step-by-step explanation:
100% of the price = $400
x % of the price = $320
we need to find x
using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80
That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%
I hope it is clear to you, feel free to ask anything about it :)
Answer:
The answer is 75 miles per hour
Step-by-step explanation:
225÷3=75 ( how many times 3 go into 225)
We can check to see if this answer is correct by multiplying 75 by 3 ( multiply 75 three times)
75×3=225
There for 75 is the correct answer
(I hope this helped you answer your question. If you want to check if I'm correct you can use a calculator! Have a wonderful day!)
