Alisiya [41]

A house on the market was valued at $327,000. after several years the value increased by 17% by how much did the house's value increase in dollars? what is the current value of the house?

How much did the house's value increase in dollars?

327,000 x 0.17 (17%) = $55,590

What is the current value of the house?

327,000 + 55,590 = $382,590

Use lengths |OQ| = 9.4 units and |OQ’| = 17.1 units to determine the scale factor r of dilation D (round to the nearest hundredt
NNADVOKAT [17]

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:

\frac{OQ'}{OQ}=\frac{17.1}{9.4}

\frac{OQ'}{OQ}=1.8191

Upon multiplying both sides of our equation by OQ we will get,

\frac{OQ'}{OQ}\times OQ=1.8191\times OQ

OQ'=1.8191\times OQ

Upon rounding our answer to nearest hundredths place we will get,

OQ'\approx 1.82\times OQ

Since side length OQ' is 1.82 times side length OQ, therefore, our scale factor (r) will be 1.82 units.
