True or false, the two expressions are equivalent.

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

Answers

Answer 1

Answer:

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

Answer 2

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

1) 150 meters (a squared + b squared = c squared so you would do 90 times 90 + 120 + 120 and then square root that to get 150)
2) 18.02 (a squared + b squared = c squared)
3) 150 (you have to find out the length which is 20 then you do 15*20 and divide that by 2 to get 150)
4) 14.21 (a squared + b squared = c squared)
5) A (8 squared + 15 squared DOES EQUAL 17 squared)

Answer:

  x = 27°

Step-by-step explanation:

Each exterior angle is equal to the  sum of the remote interior angles.

  6x = 90° +(180° -4x)

  10x = 270° . . . . . add 4x

  x = 27° . . . . . . . . divide by 10

_____

Check

6x = 162°, so the adjacent interior angle of the triangle is 180° -162° = 18°.

4x = 108°, so the adjacent interior angle of the triangle is 180° -108° = 72°.

The interior angles of the triangle are complementary, as they should be.

  18° +72° = 90°

A dilation with a scale factor of 1/3 is a reduction. A dilation with a scale factor of 2 is a reduction . which is true and which is false

Answers

Answer:

True: A dilation with a scale factor of 1/3 is a reduction.

False: A dilation with a scale factor of 2 is a reduction.

Step-by-step explanation:

A dilation with a scale factor between 0 and 1 is a reduction because the image will decrease in size.

On the other hand, a dilation with a scale factor greater than 1 is an enlargement, where the image increases in size.

So, the statement that a dilation with a 1/3 scale factor is a reduction is true.

The other statement is false, which says a dilation with a scale factor of 2 is a reduction.

A class has 30-40 students. Each boy in the class bring 15 chocolate bars for a class party to celebrate Teacher's Day. The chocolate bars are shared equally among the 20 girls of the class and their form teacher with no leftovers.
(i) How many students are there in the class?
Detailed steps please!

Answers

9514 1404 393

Answer:

  34

Step-by-step explanation:

In order to divide some multiple of 15 chocolate bars evenly by 21, the number of bars must be a multiple of the LCM of 15 and 21, which is 105. That number is 7 times 15, indicating the number of boys in the class must be a multiple of 7. The only number between 30-20 = 10 and 40-20 = 20 that is a multiple of 7 is 14.

There must be 14 boys in the class, so 34 students in total.

__

The boys brought a total of 210 chocolate bars, so each girl and the teacher received 10 of them.

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).
