True or false, the two expressions are equivalent.

3(4a - 2) and 12a - 6

Answers

Answer:

its true because 3(4a - 2) is 12a - 6

Answer:

True

Step-by-step explanation:

its true because 3(4a - 2) you would do 3 x 4a and instead of 4 - 2 you would change it to 4 + 2 after that you would do 3 x 4a = 4a + 2 which gives you

12a - 6

so yes they are equivalent

Answers

Answer:

5/1

Step-by-step explanation:

Cause I say so. Rise/run is rate of change.

answer: 5

explanation: another word for rate of change is slope. to find the slope you count the rise/run (rise over run). that means you count how many units up and how many units across.
(1, -1) is in the corner of a unit box so that’s where i like to start counting from. from there i count up and across until i find another plot that is exactly in the corner of another unit box. the next plot point in the corner of a unit box would be (2, 4). to get to that point i counted 5 units up and 1 unit across.

A plant has to grow close to the ground to resist cold and has shallow roots because the soil under it is frozen. In which biome is this plant most likely found? temperate rain forest tundra desert tropical rain forest

Answers

Answer:

tundra

Step-by-step explanation:

The plant that you have described, which has to grow close to the ground and has shallow roots because the soil under it is frozen, is most likely found in the tundra biome. Option B is correct.

What are tundra biomes?

Long, cold winters and short, cool summers characterize the tundra biome.

Here,

Because the soil beneath it is frozen, the plant you described must grow close to the ground and has shallow roots. It is most likely found in the tundra biome.

Long, cold winters and short, cool summers characterize the tundra biome. The soil in the tundra is usually frozen all year, making it difficult for plants to develop deep root systems. As a result, to withstand cold, windy conditions, many tundra plants have shallow roots and grow close to the ground. Lichens, mosses, grasses, and dwarf shrubs are examples of tundra plants.

Answer:

6 photos more if you use the fast printer

30 photos

Step-by-step explanation:

To figure out the answer, it will be much easier to figure out how many pages each printer can print in 1 minute. For the office printer, we need to divide both numbers by 12.5. This means that the office printer can print 2 pages per minute.

Do the same thing for the home printer. We need to divide both numbers by 6. This means that the home printer can print 2.5 pages per minute.

The home printer is indeed faster.

Now, we need to figure out how many more pages can the home printer print in 12 minutes. In 12 minutes, the office printer can print 24 pages. In 12 minutes, the home printer can print 30 pages. The difference in the number of pages between the faster printer and the slower one within 12 minutes is 6 pages.

Which of the following formulas could be used to determine the volume of a cone stacked on top of half a sphere?
Select all that apply.

V = lwh
V = Bh
V = 1/3 Bh
V = pi* r^2h
V = 1/3 pi* r^2h
V = 4/3 pi* r^3

Answers

Answer:

I think it is V=pi* r^2h and V = 4/3 pi* r^3 but I am not 100% sure.

Step-by-step explanation:

The correct options are 5 (1/3 pi* r^2h) and 6 (4/3 pi* r^3).

What is Volume?

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere. Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry.

As per the given data:

The formula for volume of various figure is given.

We have to find the formulas which can be used to determine the volume of a cone stacked on top of half a sphere.

Volume of a cone stacked on top of half a sphere:

= Volume of a hemisphere + Volume of a cone

= (Volume of a sphere/2) + Volume of a cone

Volume of a sphere = 4/3 pi* r^3

Volume of a cone = V = 1/3 pi* r^2h

Hence, the correct options are 5 (1/3 pi* r^2h) and 6 (4/3 pi* r^3).
