The answer is actually 80 degrees, I just took the test.
Answer:
90
Step-by-step explanation:
I took the test and 90 gives u the most variability in your outcome so ur answer is more reliable.
I think 7 of them are girls and the rest are boys and how i got this answer is I took the 28 and divided it by 4 and got 7.
Answer: 3/10. -2 3/5 = -2 6/10. -2 6/10 - -2 3/10 = - 3/10. -3/10 = 3/10 away on a number line
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 :)
