Answer:
0.90
Step-by-step explanation:
full price discounted total
month 1 49 1 50
month 2 120 5 125
month 3 101 24 125
total 270 30 300
full price discounted total
month 1 0.98 0.02 1
month 2 0.96 0.04 1
month 3 0.808 0.192 1
total x = 0.9 y = 0.10 1
x = 270 / 300 = 0.90
y = 30 / 300 = 0.10
Answer:
See solutions below
Step-by-step explanation:
From the given diagram;
AC = opposite
AB = 7 = hypotenuse
Angle of elevation = 70 degrees
Using SOH CAH TOA
Sin theta = opp/hyp
Sin theta = AC/AB
Sin 70 = AC/7
AC = 7sin70
AC = 7(0.9397)
AC = 6.58
Similarly
tan 70 = AC/BC
tan 70 = 6.58/BC
BC = 6.58/tan70
BC = 6.58/2.7475
BC = 2.39
tan m<A = BC/AC
tanm<A = 2.39/6.58
tan m<A = 0.3632
m<A = 19.96degrees

Step-by-step explanation:
Answer:
Each student would get 4 inches of ribbon
Step-by-step explanation:
Mrs. Barkley has 75 inches of ribbon and is splitting it between 18 students so you would divide 75 by 18. When you divide you get 4.166666... etc. So the answer would be 4
