Answer:
The answer to your question is 8 h
Step-by-step explanation:
Data
length of the ladder = 200 cm
distance between each rung = 20 cm
rate = 10 cm/h
fifth rung = ?
Process
1.- Calculate the total distance the tide must rise
distance = 20 cm x 4
= 80 cm because the first rung touches the water
2.- Calculate the time
rate = distance / time
-Solve for time
time = distance / rate
-Substitution
time = 80 cm / 10cm/h
-result
time = 8 h
Answer:
f(-1/2) = -4
Step-by-step explanation:
To evaluate the expression, substitute by replacing x with -1/2. Then simplify according to order of operations:
f(-1/2) = 4(-1/2) - 2
f(-1/2) = -4/2 - 2
f(-1/2) = -2 - 2
f(-1/2) = -4
Answer:
n = 8
Step-by-step explanation:
The rule for this table is multiply x by 4 to get y. To solve for n, divide y (32) by 4 to get x (8).
