<h2>Answer:</h2>

The scale factor is:

                          1/2

<h2>Step-by-step explanation:</h2>

We know that the scale factor of a dilation is the ratio of the length of the dilated i.e. transformed figure to the corresponding lengths of the original figure.

Here in the original triangle i.e. ΔABC the length of the side AC is: AC=18 units

and the corresponding side of the dilated triangle i.e. ΔA'B'C' is: A'C'= 9 units

Hence, the scale factor is given by:

\text{Scale factor}=\dfrac{\text{Length of A'C'}}{\text{Length of AC}}\\\\i.e.\\\\\text{Scale factor}=\dfrac{9}{18}\\\\\text{Scale factor}=\dfrac{1}{2}

Joes age (j) is half Martha’s (m). Combined, their age is 42. What are their ages?
svp [43]

Answer:

Joe is 14.

Martha is 28.

Step-by-step explanation:

Use the variables and information from the question to make equations.

If Joe's age is half Martha's:

(1/2)m = j     OR     2j = m

If their ages combined is 42:

m + j = 42

We can substitute the equation m=2j into equation m + j = 42, replacing "m".

m + j = 42    Substitute m for 2j

2j + j = 42     Combine like terms, terms with same varables

3j = 42     Divide both sides by 3 to isolate j

j = 14       Joe's age

Since j = 14, we can substitute it into equation m=2j to find "m".

m = 2j       Substitute j for 14

m = 2(14)     Simplify

m = 28       Martha's age

Therefore Joe is 14 and Martha is 28.

The students in Mr.​ Kim's class are discussing how to apply the properties of equality. Jared started with the equation 10 - 4=
iVinArrow [24]

<u>Answer</u>:

Jared is right.

<u>Explanation</u>:

proof 1:

10 - 4 = 6

6 = 6

second proof:

10-3 - 4 = 6 - 3

10 - 7 = 3

3 = 3

third proof:

10 - 4 - 3 = 6 - 3

10 - 7 = 3

3 = 3

Hence for all LHS = RHS proved and Jared is correct.

The plan of a patio deck is shown at the right. The scale is 2 inches: 6 feet. What are the length and width of the deck
yanalaym [24]

Answer:

5in.=15ft. 2in.=6ft.

Step-by-step explanation:

What you have to do is translate 6ft. into inches which is 72in. Then you divide that by 2in. From that you get 36in. You then take that 36in. and multiply it by the 5in for the length. from that you get 180in. You divide the 180in. by 12 to turn your inches into feet and you end up with 15ft.

I hope this helps.
