Answer:
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
Step-by-step explanation:
complementary means they add up to 90°
supplementary means they add up to 180°
TABLE 1:
88
80
65
57
50
41
45
28
14
4
TABLE 2:
176
164
132
108
90
81
60
11
2
When two angles are complementary they add up to 90 degrees
so for example if angle 1 is 2 angle two must equal 88 (they have to add up to 90)
When two angles are supplementary they must add up to 180 (so it's the same process as table 1 but instead of adding to 90 it's 180)
52.5 mi(8 km/5mi) = 84 km
Answer: well if you listened on school you wouldn't need help sooo
Step-by-step explanation: LISTEN IN SCHOOL
The original price of the dress is 142.85$
Let the original price of the dress be 'x'
After 20% discount the payable amount for the dress is
x-20x/100
=80x/100
=4x/5 first equation ( The price of the dress after 20% discount)
Now, after applying the additional sales coupon of 30%, from the first equation we get,
Payable amount for the dress will be 4x/5 - 30x/100*4x/5 ( 30% of discounted price)
= 400x-120x/5(100) second equation
But Mary paid 80 $ finally, using second equation we tell us the amount after 30% additional discount.
400x-120x/500= 80
= 280x=80*500
x = 80*500/280
=1000/7
x = 142.85 $
Hence, the original price is 142.85 $
