Question

Please help it is a four number

Answer 1

1st Question: 1st digit 1 and Answer 24

2nd Question: : 1st digit 3 and Answer 12

3rd Question: : 1st digit 3 and Answer 630 ft

4th Question: 1st digit 1 and Answer: ¾

4 digit combination: = 1331

Explanation:

The scale factor is a number that is used to dilate or reduce a geometric figure. It is the ratio of the length of a side of the dilated figure to the corresponding side of the original figure.

`\sf \textsf{ Scale factor} =\frac{\textsf{ dilated side length }}{\textsf{original side length}}`

Question 1:

Length = 4 units

Length of enlarge square = scale factor × length

= 1.5 × 4

= 6 units

Now,

The perimeter of the enlarged square is: 4 × enlarged length

= 4 × 6

= 24 units

Question 2:

Since the two triangles are similar, the ratio of their corresponding sides is equal.

`\sf (x )/(9) = (8 )/( 6)`

Solving for x, we get:

`\sf x = (8 )/( 6)* 9`

`\sf x = 12 units`

Question 3:

Since the two triangles are similar, the ratio of their corresponding sides is equal.

`\sf (x )/(140) = (18 )/( 4)`

Solving for x, we get:

`\sf x = (18 )/( 4) * 140`

`\sf x = 630`

Question 4:

The scale factor is the ratio of the corresponding sides of the two similar figures.

`\sf \textsf{Scale factor } = ( 9 )/( 12 )`

`\sf \textsf{Scale factor } = \frac{ 3 * \cancel{3} }{ 4* \cancel{3} }`

`\sf \textsf{Scale factor } = ( 3 )/( 4 )`
