Answer:
a
Step-by-step explanation:
Associative Property states that grouping symbols does not affect the outcome. This property works for Addition and Multiplication:
2 + (3 + 4) = (2 + 3) + 4
6 • (5 • 4) = (6 • 5) • 4
1.609/5280 = 3.2/x....1.609 km to 5380 ft = 3.2 km to x ft
cross multiply because this is a proportion
(1.609)(x) = (5280)(3.2)
1.609x = 16896
x = 16896/1.609
x = 10,500 ft <===
Answer:
∠ A ≈ 48°
Step-by-step explanation:
Using the Cosine rule to find an angle
cosA = 
with a = 10, b = 13 and c = 11
cosA = 
= 
= 
, thus
A = 
( ) ≈ 48° ( to the nearest degree )
Well first you want to add the sales tax which would be 8% of 40 which is 3.2. So it costs $43.2 without the discount. so then you want to find 20% of 43.2 which is 8.64. So the last step is to subtract 8.64 from 43.2 which is
43.2 - 8.64 = $34.56 is your answer
