SOLUTION:
a ) Write an equation in standard form that models your earnings.
8x + 6y = $114
b ) You worked 10 hours as a hair washer. How many hours did you work as a host?
8x + 6y = $114
8x + 6 ( 10 ) = 114
8x + 60 = 114
8x = 114 - 60
8x = 54
x = 54 / 8
x = 27 / 4 hours
x = 6.75 hours
x = 6 hours and 45 minutes
Answer:
1,680
Step-by-step explanation:
There are 8 students to choose for the first chair. After we choose one, we have 7 students to choose from for the second chair, 6 for the third chair, etc.
8 * 7 * 6 * 5 = 1680 (ans)
Answer:
B.$8.98
Step-by-step explanation:
We need to determine the cost per ounce. We divide the cost by the number of ounces
3.59/16 =.224375 per ounce
Take the price per ounce and multiply by the number of ounces to determine the price of the 40 ounce jar
.224375 * 40 =8.975
Rounding to the nearest cent
8.98 for a 40 ounce jar
Answer:
58 seconds
Step-by-step explanation:
Given:
Initial mass of water = 1 kg
Specific energy = 2297 kJ/kg
Heat supplied by the stove = 20 kJ/s
Now,
Half water is to be vaporized i.e 0.5 kg
Thus, heat required for vaporizing 0.5 kg water = mass × specific heat
or
heat required for vaporizing 0.5 kg water = 0.5 × 2297 = 1148.5 kJ
Therefore,
time taken to provide the required heat = 
or
time taken to provide the required heat = 
or
time taken to provide the required heat = 57.425 ≈ 58 seconds
