What are the two things that happen to water molecules when heat energy is added to air?

Answers

Answer:

The more thermal energy added, the greater the attraction between molecules. The molecules gain kinetic energy, move farther apart, and become a gas. The water molecules become packed closer together, and their temperature increases. Each water molecule gives up kinetic energy and eventually stops moving.

Last week, a chocolate shop sold 4 7/8 ounces of white chocolate. It sold 3 times as much milk chocolate as white chocolate. How many ounces of milk chocolate did the shop sell?

Answers

Answer:

3 21/32 oz.

Step-by-step explanation:

4 7/8 = 39/32

39/32 x 2 = 117/32 = 3 21/32 ounces

amt. of chocolate sold:
milk
white ⬜️ (since 3 times of milk chocolate was sold)

hence to find 1 unit, we divide 4 7/8 by 4,
(4 7/8) / 4 = 1 7/32

3 units = 1 7/32 x 3 = 3 21/32
The shop sold 3 21/32 ounces of milk chocolate.

Terry is an up-and-coming florist who specializes in weddings. He uses 5 roses, 3 daisies, and 4 bundles of green filler to make one bouquet. If r is the cost of a rose, d is the cost of a daisy, and f is the cost of a bundle of green filler, which expression represents the cost for making 75 bouquets?
75r +75d + 75f + 12
(5r + 3d + 4f) + 75
75(5r) + 75(3d) + 75(4f)
75(5r + 3d + 4f)

Answers

Answer: The last two are right

Step-by-step explanation: 75x5= $375, 75x3=$225, 75x4=$300.

Add all the sums together and you will get the cost of 75 bouquets, which is $900. - NUMBER 3

5+3+4=12, 12x75=$900

Sorry if I'm wrong first time doing this.

Answer:

option (4) is correct. 75( 5r + 3d + 4f ) expression represents the cost for making 75 bouquets.

Step-by-step explanation:

Given: r is the cost of a rose, d is the cost of a daisy, and f is the cost of a bundle of green filler.

Terry uses 5 roses, 3 daisies, and 4 bundles of green filler to make one bouquet.

Thus, cost of one bouquet = cost of each flower used × number of flower used.

Total cost of one bouquet= 5r+3d+4f

Thus, cost for making 75 bouquets = 75 × cost of one bouquet

= 75( 5r + 3d + 4f )

Thus, option (4) is correct. 75( 5r + 3d + 4f ) is the correct expression to represents the cost for making 75 bouquets

Is this right? I chose the last 3. Please read all of them though.
