Answer:

first of all convert the hours to minutes

2/3×60=40

convert the seconds to minutes

540÷60=9

add the minutes

40+9=40

so he spent

90-40=50 more minutes in doing his homework.

Complete question :

What is the average amount of milk used for an order of pancakes? Enter your answer as a fraction or mixed number in simplest form.

1/2c, 1/4c, 1/2c, 3/4c, 1/2c, 3/4c, 1/2c, 1/4c, 1/2c, 1/2c

Answer:

1/2c

Step-by-step explanation:

Taking the sum :

1/2c + 1/4c + 1/2c + 3/4c + 1/2c + 3/4c + 1/2c + 1/4c + 1/2c + 1/2c = 6/2c + 2/4c + 6/4c

6/2c + 2/4c + 6/4c

3/1 + 1/2 + 3/2 = (6 + 1 + 3) / 2 = 10 /2

= 5

Total number of orders = 10

Average = 5 / 10 = 1 /2 c

Which graph shows the solution to this system of inequalities?<br><br> y&lt;-1/3x+1<br> y&lt;_2x-3
kari74 [83]

The graph that shows the solution to the system of inequalities is: C (see the image attached below).

<h3>How to Determine the Graph of the Solution to a System of Inequalities?</h3>

Given the following systems of inequalities:

y < -1/3x + 1

y ≤ 2x - 3

Below are the features of the graph that represents a solution to the system of inequalities:

  • The boundary line of y < -1/3x + 1 would be a dashed line and the shaded area would be below it, because of the inequality sign, "<".
  • The boundary lines of y ≤ 2x - 3 would be a solid line and the shaded area would be below it, because of the inequality sign, "≤".
  • The slope of the shaded line that represents  y < -1/3x + 1, would be -1/3, and the line would be a decreasing line which intersects the y-axis at 1.
  • The slope of the line that represents y ≤ 2x - 3, would be 2, and the line would also be an increasing line that intersects the y-axis at -3.

Therefore, the graph that shows the solution to the system of inequalities is: C (see the image attached below).
