7/8 there you go the right answer xD
Answer:
The plumber worked 50 hours, and his assistant worked 25 hours.
Step-by-step explanation:
Since a plumber and his assistant work together to replace the pipes in an old house, and the plumber charges $ 30 an hour for his own labor and $ 20 an hour for his assistant's labor, and the plumber works twice as long as his assistant on this job, and the labor charge on the final bill is $ 2000, to determine how long did the plumber and his assistant work on this job the following calculation must be performed:
40 x 30 + 20 x 20 = 1200 + 400 = 1600
50 x 30 + 25 x 20 = 1500 + 500 = 2000
Therefore, the plumber worked 50 hours, and his assistant worked 25 hours.
Answer:
$33.81
Step-by-step explanation:
2.49*3 = 7.47 dollars for 3 pounds of strawberries
3.19*2 = 6.38 dollars for 2 pounds of blueberries
4.99*4 = 19.96 dollars for 4 pounds of pineapple
7.47 + 6.38 + 19.96 = 33.81 dollars spent in total
If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula.

. So our slope is 7/5. The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is

, choice D from above.
Answer:
The value of y is 847 for x=11
Step-by-step explanation:
It is given that y is directly proportional to the square of x
This can be written mathematically as:

Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k

Given that "When x is 5, y is 175"

Putting the value of k

Now putting x = 11

Hence,
The value of y is 847 for x=11
