Answer: L ≈ 2.0 m
Step-by-step explanation:
Lsin40 = h
Lsin55 = h + 0.35
Lsin55 = Lsin40 + 0.35
Lsin55 - Lsin40 = 0.35
L(sin55 - sin40) = 0.35
L = 0.35 / (sin55 - sin40)
L = 1.98452 ≈ 2.0 m
Answer:
1 A the first store.
2. B The second store.
Step-by-step explanation:
1. The store with the dearest towel is The First one ( $20 compared with $18).
2. The equation for the cost in the first store is P = 20n + 25.
The cost in the second store is given by P = 18n + 35.
For 15 towels first store charges:
20 * 15 + 25 = $325.
Second store charges:
18 * 15 + 35 = $305.
Answer:
Symbols of inclusion are symbols used in mathematical expressions that group terms or factors together. They indicate that when we are simplifying expressions, we are to perform what's inside the symbols first. The three types of symbols of inclusion are parentheses, brackets, and braces.
C. 25(-5) = 125 this is the answer
