The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room are in the ratio 4:3:2. The combined area of these three rooms is 189 square feet. What is the area of the playroom?

Answers

The combined area of these three rooms is 189 ft².
Therefore we have the equation
4x + 3x + 2x = 189
9x = 189 |:9
x = 21 ft²
area of the kitchen = 4x = 4(21) = 84 ft²
area of the playroom = 3x = 3(21) = 63 ft²
area of the dinning room = 2x = 2(21) = 42 ft²

a) In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race.
If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?

Answers

Answer:

233.53 s

Step-by-step explanation:

The sum of best times for the legs is ...

56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds

Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.

The Answer is 233.53sec

Lin cooked a pot of soup, then put half the soup in the freezer for a while. Now the soup in the pot is hot, and the soup in the freezer is cold. What is the difference between the molecules of the soup in the pot and the molecules of the soup in the freezer?

Answers

Answer:

The molecules of the soup in the freezer are very slow as for the soup in the pot the molecules are moving fast

Mark me brainliest plz ;)

The molecules of the soup in freezer will be in static (or motionless) state while the molecules of the soup in the pot will be in dynamic zig zag motional state.

What are intermolecular bonding forces?

Intermolecular attractions are attractions between one molecule and a neighboring molecule. Attractive intermolecular forces are categorized into the following types:

Hydrogen bondingIon–dipole forces and ion–induced dipole forcesVan der Waals forces – Keesom force, Debye force, and London dispersion force

Given is that Lin cooked a pot of soup, then put half the soup in the freezer for a while. Now the soup in the pot is hot, and the soup in the freezer is cold.

For the soup in freezer, the kinetic energy of the molecules of the soup will be very small. Hence, they will be static (or motionless) state.For the soup in pot, the kinetic energy of the molecules of the soup will be very large. Hence, they will be in dynamic zig zag motional state.

Therefore, the molecules of the soup in freezer will be in static (or motionless) state while the molecules of the soup in the pot will be in dynamic zig zag motional state.

Several items in a store are on sale. Complete the table with the correct prices.

Answers

Answer:

1.$36

2.$35

3.$51

4.$43

Answer:

1.) $35

2.) $36

3.)$51

4.)$43

Step-by-step explanation:

1.)30% of 50 is 15 and you would subtract the 15 from 50 to get your discount.

2.)55% of 80 is 44 and you would subtract 44 from 80 to get your after price.

3.)For this one, I divided the discount price by 3 and multiplied it by 4 to get the original price since 1/4 was taken from it or 25%.

4.) There was only one option left.
