Answer:
She is paid $6.25.hour at the concession and $8.50 as a lifeguard.
Step-by-step explanation:
We know:
18 hours as a lifeguard
12 hours at concession
Total earned = $228
18L + 12C = 228
Then:
24 hours as a lifeguard
8 hours at concession
Total earned = $254
24L + 8C = 254
Move one equation around to get one variable by itself: in this case we can solve for L:
18L + 12C = 228
18L = 228 - 12C
L = (228/18) - (12/18)C
Plug in for L:
24((228/18) - (12/18)C) + 8C = 254
Solve for C:
C = 6.25
Now that we know C, plug in value for C and solve for L:
18L + 12(6.25) = 228
L = 8.5
So she is paid $6.25.hour at the concession and $8.50 as a lifeguard.
Answer: 8.5 cups of flour.
Step-by-step explanation: So he first has 19/2 cups of flour, 19/2 cups of flour is the recipe, which is 9.5 cups of flour. He finishes the recipe with 17/2 cups left, which is 8.5 cups of flour.
Answer:
step 1. for time = 1, distance = 6.
step 2. if time = 4/3 then distance = 6(4/3) = 8
step 3. if distance = 9 then time = 9/6 = 3/2.
Answer:
a. y^2 = 8x.
Step-by-step explanation:
The general equation for this type of parabola is y^2 = 4ax where a is the distance between the vertex and the focus. The focal width = 4a.
So the answer to this is y^2 = 8x.
