Answer:
x=1
Step-by-step explanation:
Answer: 20.25ft
1. Find what 8 inches in scale equal for the height of the house.
we will do this step by multiplying.
2in=4.5
8=?
to find...
2x4=8
so
4.5x4=18
2. Find what 1 inch on the scale is equal to for the height of the house.
we will do this by dividing 4.5 by 2
4.5/2=2.25
3. Add both the values for step 1 and 2.
we will do this by just adding them both
18+2.25=20.25
<h2>Why is this our answer?</h2>
This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!
My gratitude attitude - THANKS!
Since we are trying to find the number of sequences can be made <em>without repetition</em>, we are going to use a combination.
The formula for combinations is:

is the total number of elements in the set
is the number of those elements you are desiring
Since there are 10 total digits,
in this scenario. Since we are choosing 6 digits of the 10 for our sequence,
in this scenario. Thus, we are trying to find
. This can be found as shown:

There are 210 total combinations.
Answer:
Length=6
Width=3
Step-by-step explanation:
Area:L*W
Area= 6*3=18
Perimeter: 2 (L+W)
Perimeter= 2 (6+3)= 12+6=18
