Answer:
3/5
Step-by-step explanation:
The given ratio is ...
water : juice = 3 : 5
Divide both numbers by 5 to see how much water is needed with 1 cup of juice.
water : juice = (3/5) : 1
3/5 parts of water are mixed with 1 part of juice.
Answer:
10.25
Step-by-step explanation:
Unit price means per 1
71.75/7 = 10.25 each
Picture a right triangle whose hypotenuse is of unknown length. Let's call that length L. The triangle side opposite the 70 degree angle is then 20 feet. I'd suggest you actually draw this triangle.
Then, using the definition of the sine function,
sin 70 deg = opp / hyp = (20 ft) / L. Transforming this equation, L sin 70 deg = 20 ft. Solving for L:
L = (20 ft) / (sin 70 deg) = 21.28 ft
The ladder length must be 21.28 ft.
