Each morning a deli worker has to make several pies and peel a bucket of potatoes. on Monday it took the worker 2 h to make the pies and an average of 1.5 min to peel each potato. on Tuesday the worker finished the work in the amount of time but it took 2.5 h to make the pies and an average of 1 min to peel each potato. about how many potatoes are in a bucket?• what qualities do you know and how are they related to each other?
• how can you use the known and unknown quantities to write an equation for this situation?

Answers

Answer 1

Answer: Let the number of Potatoes = P

On Monday the time spent was 2 hours + 1.5*P minutes
Convert the time to make the pies into minutes = 120 minutres
Therefore on Monday the worker took

120 + 1.5P minutes

On Tuesday the worker took 2.5 hours (150 minutes) + 1minute x P
ie
150 + P minutes

We are told that the times are the same therefore
120 + 1.5P = 150 + P
subtract P from both sides of the equation
120 + 0.5P = 150
Subtract 120 from both sides of the equation
0.5P = 30

Therefore P = 30/0.5 = 60

There are 60 potatoes in the bucket.

The graph shows the amount of money paid when purchasing bags of candy at the zoo: A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 2 and 2, 4 and 3, 6. These points are joined by a line. The label on the x-axis is Bags of candy. The title on the y-axis is Total cost in dollars. What does the point (0, 0) on the graph represent?

If 5x^2 - 15x = 0 and x ≠ 0, find the value of x.(A) -10
(B) -3
(C) 10
(D) 5
(E) 3

Answers

5x^2 - 15x = 0
5x (x - 3) = 0
5x = 0
x = 0
x - 3 = 0
x = 3

Since x cannot equal 0, x = 3 is your answer.

Imagine that you are given two linear equations in slope-intercept form. You notice that the slopes are the same, but the y-intercepts are different. How many solutions would you expect for this system of equations?A. Cannot be determined
B. 0
C. 1
D. Infinitely many

Answers

If two lines have the same slope and different intercepts, then they will never cross each other; they are parallel lines. Therefore, they have no solutions since a solution is where the lines cross.
