Answer:
1.07x
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Leila is buying a dinosaur model. The price of the model is x dollars, and she also has to pay a 7%, percent tax. </em>
<em>Which of the following expressions could represent how much Leila pays in total for the model?</em>
My answer:
Given the information:
The original price of the model: x
Taxed Amount = 7% of x
<=> That is, 7% in decimal multiplied with "x"
<=> = 0.07x
=> Total amount Leila needs to pay is:
= The original price + Taxed Amount
= x + 0.07x
= 1.07x
Therefore, the expressions could represent how much Leila pays in total for the model 1.07x
Hope it will find you well.

Answer:
Scale factor = 1.82 units.
Step-by-step explanation:
We have been given that side length OQ of our prei-mage is 9.4 units and side length OQ' after dilation is 17.1 units. Since our pre-image (original image) is smaller than our new image, so our scale factor (r) will be greater than 1.
Since we know that in a dilation, the sides of the pre-image and the corresponding sides of the image are proportional, so we will use proportion to find a scale factor our given side lengths as:
Upon multiplying both sides of our equation by OQ we will get,
Upon rounding our answer to nearest hundredths place we will get,
Since side length OQ' is 1.82 times side length OQ, therefore, our scale factor (r) will be 1.82 units.
