Answer:

See explanation

Step-by-step explanation:

Statement Reason

1. the diagram shows segment AC with point B on this segment, then

$AB+BC=AC$ <u>Segment addition postulate</u>

2. Given $AB=2x,\ BC=6x+8,\ AC=32,$ then

$2x+6x+8=32$ <u>Substitution property</u>

3. Simplify the equation as follows

$8x+8=32$ <u>Combine like terms</u>

4. Subtract 8 from both sides

$8x+8-8=32-8\\ \\8x=24$ <u>Subtraction property of equality</u>

5. Divide by 8:

$x=3$ <u>Division property of equality</u>

a. This is the geometric sequence: a1 = 1.5 m = 150 cm, r = 0.74

The formula now is an = a1 x r ^ n-1

Just substitute a1 = 150 cm and r = 0.74

an = 150 x (0.74) ^ n – 1

b. The second part is:

A6 = 150 x 0.74 ^ 6-1

= 150 x 0.74 ^5

= 150 x 0.221906624

= 33.28509936 cm

Colby wants to set up square tiles on the top of a wooden box. The top of the wooden box is a rectangle 7 1/2 inches long and 5

Andrei [34K]

Yes he can, because when the area of the top of the box is divided by 3/4, you get a whole number, meaning there would be no tile pieces left over, which means that he could cover the top. SEE PICTURE FOR WORK.

What is the mean absolute deviation of the data set? 12, 15, 7, 4, 9, 10, 9, 6

bearhunter [10]

Here is an example:
Find the MAD of 2,4,6,8 Step 1 : Find the mean of the data : (2+4+6+8) / 4 = 20/5 = 4 Step 2 : Find the distance between each data and mean. Distance between 2 and 5 is 3 Distance between 4 and 5 is 1 Distance between 6 and 5 is 1 Distance between 8 and 5 is 3
Step 3 : Add all the distances : 3+1+1+3 = 8
Step 4 : Divide it by the number of data : 8 / 4 = 2 2 is the average absolute deviation.

Jatonia plans to purchase 4

steposvetlana [31]

Hey there!

All we need to do is multiply the unit price of the pencil ($.35) by how many pencils she wants to buy (4)

$.35 x 4 = $1.40

Therefore, she will pay $1.40 for 4 pencils

Hope this helps you!

God bless ❤️
