Answer:
219.9 feet to the nearest tenth.
Step-by-step explanation:
Use trigonometry:
tan 35 = opposite / adjacent side
= 154/x
x = 154 / tan35
= 219.93
The unit that would be the best for measuring the amount of water in a bathtub would be up to the scale used. Out of the given choices, liters seems to be the best choice. So, the correct answer will be C.

Answer: 15 dimes
Step-by-step explanation:
Nickels are 5 cents and dimes are 10 cents and since they are a total of 1.95 coins in total we can set up the two equations and solve for how much there are for each of the money.
x + y = 24
0.05x + 0.10y = 1.95 so solve for y and x is the number of nickels while y is the number of dimes.
x+y=24
-y -y
x = -1y +24
0.05(-1y +24) + 0.10y = 1.95
-0.05y + 1.2 + 0.10y = 1.95
0.05y + 1.2 = 1.95
-1.2 -1.2
0.05y = 0.75
y = 15
