The length of ​ AB¯¯¯¯¯ ​ is 10 inches. A dilation with a scale factor of 25 is applied. What is the length of the image of ​ AB¯¯¯¯¯ ​ ?

Answers

Answer 1
Answer:

Answer:

length of image of AB is 4 inches.

Step-by-step explanation:

Scale factor(k) is defined as the ratio of  image to the pre-image.

i.e,

k = \frac{\text{Image}}{\text{Pre-image}}

as per the statement:

The length of ​ AB ​ is 10 inches. A dilation with a scale factor of (2)/(5)

⇒ k= (2)/(5) =0.4 and Length of pre-image AB = 10 inches.

by definition of scale factor:

\text{length of image AB} = k \cdot \text{Length of Pre-image AB}

Substitute the given values we have;

\text{length of image AB} = 0.4 \cdot 10

Simplify:

\text{length of image AB} =4 inches.

Therefore, the length of image AB is 4 inches.

A rectangular park has an area of 2/3 square mile. The length of the park is 2 2/3 the width of the park. What is the width of the park?

Answers

Area of the rectangular park = 2/3 square mile
Let us assume the width of the rectangular park = x
Then
The length of the rectangular park = 2 2/3 * x mile
                                                       = 8x/3 mile
Then
Area of the rectangular park = Length * Width
2/3 = (8x/3) * x
2/3 = 8x^2/3
(2 * 3)/3 = 8x^2
2 = 8x^2
x^2 = 2/8
x^2 = 1/4
x^2 = (1/2)^2
x = 1/2
So the width of the park is 1/2 feet.

Sara's savings account balance changed by -$34 one week and by -$67 the next week .Which amount represents the greater change?

Answers

Answer:

Change in one week is more than the change in the next week

Step-by-step explanation:

Change in Sara's savings account balance in one week = - \$ 34

Change in Sara's savings account balance in next week = - \$ 67

Tens digit in 34 = 3

Tens digit in 67 = 6

If we compare the tens digit of 34 and 67, we get 6> 3

So, 67> 34

On multiplying both sides by -1 , we get -67< -34.

{ We know that negative sign changes sign of inequality }

So, we get change in one week is more than the change in the next week .
The greater change is represented by the absolute magnitude

|-34| = 34
|-67| = 67

67 > 34

-67 represents the greater change
