Answer:
The number is 60
Step-by-step explanation:
65% out of what number is 39
.65 * n = 39
Divide by .65 on each side
.65*n/.65 = 39/.65
n = 60
4.50 ÷ 5 = 0.9
The unit price is $0.9 or ¢9.
Answer:
1,737.3 feet
Step-by-step explanation:
Let's assume the length of the bridge consists of 2 right triangles as shown in the diagram. Use pythagorean theorem to find the other missing leg of each right triangle.
Let the missing leg for each triangle be x and y respectively.
Length of bridge = x + y
✔️x = √(1115² - 860²) = √503,625
x ≈ 709.7 (nearest tenth)
✔️y = √(1340² - 860²)
y ≈ 1,027.6 (nearest tenth)
✔️ Length of bridge = 709.7 + 1,027.6 = 1,737.3 ft
The Answer is A.(you are welcome)
