Answer:

k = 8

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 32 when x = 4, then

32 = 4k ( divide both sides by 4 )

8 = k

Do you think that civilians should be targeted in warfare? Why or why not?
jasenka [17]

When countries are at war, the general rule is that civilians should not be targeted and I <u>support </u>this notion.

<h3>The Concept of War</h3>
  • War is fought by nations to assert dominance and achieve certain conditions.
  • War is fought by soldiers who pick of weapons to engage in war.

Civilians should therefore not be targeted because they have not picked up weapons to engage in the fight and so cannot be said to be targets. It makes no sense to leave the person you are fighting and who wants to fight you, to fight those who are not interested in fighting.

In conclusion, civilians should not be targeted.

1. 4/12 , 6/8

2. 16/12 , 3/4*

3. 3/2 , 15/14

4. 10/16 , 5/8

10/16 = 5/8

Which ratio forms a proportion with 9/15?

1. 6/10

1. 1.1 kg

2. 1.8 kg

3. 5.5 kg

4. 4.7 kg

2.5 lbs * (1 kg/2.2 lbs) =

Solve the proportion using number sense. 2/8 = x/ 48

1. 6

2. 12

3. 16

4. 8

8 * 6 = 48

so what is 2 times 6 ?

or another way

1/4 * 48 = 12

Solve the proportion using cross products. 18/20 = k/110

1. 99

2. 122

3. 3.3

4. 2.9

20 k = 18*110

2 k = 18 *11

k = 9 * 11

Are the ratios 8/12 and 10/25 proportional? Explain

8/12 = 2/3

10/15 = 2/3 so no way 10/25 is 2/3
