Serhud [2]

Answer:

D -2/5

Step-by-step explanation:

So first you count up or down from a point, that's 2

then you'll count side to side that's 5

2/5

but this is a negative slope because it's pointing up to the left

-2/5 is the slope

Could you please help me with this? It’s a problem from my grandson’s homework.
gulaghasi [49]

SOLUTION

From the question given, the cost of the toy truck is $36.50 before tax.

Now, the store selling the toy truck adds a 6% sales tax. This means

\begin{gathered} 6\%\times36.50 \\ =\frac{6}{100}\times36.50 \\ =\frac{6\times36.50}{100} \\ =\frac{219}{100} \\ =2.19\text{ dollars} \end{gathered}

Now, we will add this $2.19 to the initial cost, we have

2.19+36.50=38.69

This gives $38.69.

Finally we will do a discount of 10%. 10% discount is

\begin{gathered} 10\%\times38.69 \\ \frac{10}{100}\times38.69 \\ =\frac{10\times38.69}{100} \\ =\frac{386.9}{100} \\ =3.869 \end{gathered}

We will then subtract this 3.869 from 38.69, we get

\begin{gathered} 38.69-3.869 \\ =34.821 \end{gathered}

That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82

Is there a dilation that maps shape I onto shape II? If so, what is the scale factor, and is it an enlargement or a reduction?
katrin2010 [14]

Answer:

Enlargement.

Scale Factor: 3

Step-by-step explanation:

Use points to find the enlargement. Typically, you will use all the points.

A(1 , 1) ⇒ A'(3 , 3)

B(2 , 1) ⇒ B'(6 , 3)

C(1 , 2) ⇒ C'(3 , 6)

D(2 , 2) ⇒ D'(6 , 6)

To find the scale factor, simply divide the Point' with the original Point. Use any number.

A'(3 , 3)/(A(1 , 1)) = 3

B'(6 , 3)/(B(2 , 1)) = 3

C'(3 , 6)/(C(1 , 2)) = 3

D'(6 , 6)/(D(2 , 2)) = 3

Your scale factor is 3.
