The smallest mass of sugar for which that will be possible will be <u>30.5g.</u>

Since we're given the information that each heap contains either 27g, 45g, 30g, or 20g, then in order to calculate the smallest mass of sugar that can be divided to get equal heaps, we've to find the average of the numbers given and this will be:

= (27g + 45g + 30g + 20g) / 4

= 122g / 4

= 30.5g

In conclusion, the correct option is 30.5g.

Sergio [31]
Evaluate each of the expressions for the given values of the variables and see if the condition is met.

8000*4 +5500*6 = 65000 ≤ 75000 . . . true

52*4 +38*6 = 436 ≥ 320 . . . . . . . . . . . . . true

Yes, the company can meet both its expectations by building 4 cars and 6 motorbikes.

Of course, another way to work this is to draw the graph and see if the offered point is in the feasible region. It is.

Madelyn is working two summer jobs, making $20 per hour lifeguarding and making $12 per hour clearing tables. In a given week, s
Kamila [148]

Answer:

The possible values of the number of hours clearing tables are 2 , 3 , 4 , 5 hours

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- Madelyn is making $20 per hour life guarding

- She is making $12 per hour clearing tables

- She can work no more than 13 total hours

∴ The greatest time she can work is 13 hours (≤)

- She must earn no less than $180

∴ The least money she wants to earn is $180 (≥)

- If Madelyn worked 8 hours life guarding and assume that she

 worked x hours clearing tables

∵ She can work no more than 13 hours

∴ 8 + x ≤ 13

- Subtract 8 from both sides

∴ x ≤ 5 ⇒ (1)

∵ She must earn no less than $180

∴ 8 × 20 + x × 12 ≥ 180

∴ 160 + 12x ≥ 180

- Subtract 60 from both sides

∴ 12x ≥ 20 ⇒ (2)

- From equation (1) ⇒ x = 1 , 2 , 3 , 4 , 5

- Substitute x in equation (2) by these values to find the right values

 of x

# If x = 1

∴ 12(1) ≥ 20

- But 12 is less than 20

∴ x can not be 1

# x = 2

∴ 12(2) ≥ 20

∴ 24 ≥ 20

- 24 is greater than 20 then x can be 2

∵ 3 , 4 , 5 greater than 2

∴ All of them give answers greater than 20

∴ x can be 3 , 4, 5

∵ x represents the number of hours for clearing tables

∴ The possible values of the number of hours clearing tables are

   2 , 3 , 4 , 5 hours
