Step-by-step explanation:

-5 ( a-2b+3c -4d) - (-3) (4a -3b+2c-d)

Distribute

-5a+10b-15c+20d+12a-9b+6c-3d

Combine like terms

7a+b-9c+17d

7a + b - 9c + 17d

step-by-step explanation

(- 5)( a - 2b +3c - 4d ) - (-3)( 4a - 3b+2c - d )

- 5( a - 2b + 3c - 4d ) - (-3)( 4a - 3b + 2c - d)

Using Distributive property

- 5a + 10b - 15c + 20d + 12 a - 9b + 6c - 3d

Arranging like terms together

(π = 3.14)

192.78 inches
246.78 inches
277.56 inches
331.56 inches

please help lol

Answers

Answer:

The answer is 192.78 inches

Step-by-step explanation:

An oval is formed by a rectangle with semicircles at each end. We can visualize this easily.

The length of the rectangle is 54 inches.

The width of the rectangle is 27 inches.

The perimeter of rectangle is =  

=  

= 162 inches

And because there are two semicircles, we can combine them to form a circle. So, perimeter of a circle is called a circumference.

The width of the rectangle forms the diameter, so its half will be the radius.

r =  

The circumference is given by :  

=  inches

Now as the described oval shape is a complete figure without lines inside, we will subtract the width of both sides of the rectangle from the complete perimeter.

The complete perimeter is =  inches

The inner edge perimeter will be =  = 192.78 inches

A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?

Answers

Answer:

Step-by-step explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

3.14(18^2) basically do that

ABCDEFGH is a rectangular prism with CD=5, AD=6, and AE=8. Find the volume of tetrahedron ABCF.

Answers

Answer:

40

Step-by-step explanation:

the volume of tetrahedron ABCF =

⅓× ½×5×6×8 = 40

The volume of the given tetrahedron ABCF will be 40 cube units.

What is a tetrahedron?

A tetrahedron is a polyhedron having four faces, six edges, and four vertices, all of which are triangles. It is also known as a triangular pyramid with a triangle base.

The ABCDEFGH is a rectangular prism given in the question, which has :

CD = 5, AD = 6, and AE = 8

We have to determine the volume of tetrahedron ABCF.

As per the question, the required solution would be as:

The volume of tetrahedron ABCF = 1/3 × 1/2 × 5 × 6 × 8

Apply the multiplication operation, and we get

The volume of tetrahedron ABCF = 40 cube units

Thus, the volume of the given tetrahedron ABCF will be 40 cube units.

Step 1: Multiply 60% by 40

40 x .60 = 24

24 is 60 percent of 40

Step 2: If 24 was 25% of n, then we have to divide 100 by 25 to see how much we have to multiply 24 by.

100 ÷ 25 = 4
