The three items cost altogether is : 111.32 + 28.75 + 73.21 = 213.28
So, he must work 213.28 : 8.75 = 24.3748571429...
Since if he works 24 hours, he wouldn't have enough money to buy the 3 items, so he must work 24 + 1 = 25 hours.
Recheck : 25 x 8.75 = 218.75 ( > 213.28)
The required equation of the line passing the coordinates will be y = 3/4x - 1/4
<h3 /><h3>Equation of a line</h3>
The standard equation of a line is expressed as y= mx + b
where
m is the slope
b is the y-intercept
Given the coordinate points on a line (3, 2) and (-1, -1)
Slope = -1-2/-1-3
Slope = 3/4
Determine the y-intercept
2 = 3/4(3) + b
2 = 9/4 + b
b = 2 - 9/4
b = -1/4
The required equation of the line passing the coordinates will be y = 3/4x - 1/4

Answer:
The answer is b
Step-by-step explanation:
I just took the quiz
Answer:
40 mL/s
Step-by-step explanation:
first let's convert liters (L) to milliliters (mL).
1 Liter = 1000 milliliters.
so 144 L/h * 1000 = 144000.
now let's convert hours (h) to seconds (s)
we know that one hour is 60 minutes, and 1 minute is 60 seconds so we do 60 * 60 = 3600 which is the amount of seconds in an hour.
now we divide 144000 / 3600 = 40
This can be easily figured out. Check to see what points are on the bottom and that is your answer.
B
