Answer:

24 students

Step-by-step explanation:

If 60% equals 72, then 20% would be 1/3 of 72 which is 24.

Answer:

24 students selected milk

Step-by-step explanation:

Let x be the total number of students,

Since, 60% of students selected soda,

⇒ Number of students who selected soda = 60% of x = 0.6x

According to the question,

0.6x = 72

Divide both sides by 0.6,

⇒ x = 120

Now, 20% students selected milk

Hence, the number of student who selected milk = 20% of 120 = 0.20 × 120 = 24

2(x-1) ≥ 10 or 3-4x &gt; 15<br> Solve the compound inequality, and show work!
Veseljchak [2.6K]

Answer:

x\geq 6\text{ or } x

Step-by-step explanation:

We have the compound inequality:

2(x-1)\geq10\text{ or } 3-4x>15

Let's solve each of them individually first:

We have:

2(x-1)\geq10

Divide both sides by 2:

x-1\geq5

Add 1 to both sides:

x\geq6

We have:

3-4x>15

Subtract from both sides:

-4x>12

Divide both sides by -4:  

x

Hence, our solution set is:

x\geq 6\text{ or } x

lisov135 [29]

Answer:

t>15  will be inequality which shows the times there will be more than 10 gallons in the barrel.

Step-by-step explanation:

To determine:

Write an inequality showing the times there will be more than 10 gallons in the barrel.

Information Fetching and Solution Steps:

  • Skylar is filling a barrel with water.
  • The graph shows the relationship between time in minutes and the gallons of water in the barrel.

As the questions asks to determine the inequality showing the times there will be more than 10 gallons in the barrel.

For inequalities with 'more than', we use the 'greater than' symbol.

The graph shows that at time 15 minutes, the number of gallons of water is being shown as 10. As we have to determine the inequality for the time there will be more than 10 gallons in the barrel. So, time must be greater than 15 when there will be more than 10 gallons in the barrel.

If time is represented by 't', then the inequality showing the times there will be more than 10 gallons in the barrel will be:

                                                                   t>15

Therefore,  t>15  will be inequality which shows the times there will be more than 10 gallons in the barrel.
