1/2 = 18 cut
Cut= 1/36
So if victor rides for time t+ 1/36
Alex rides for t
D= 18 (t + 1/36) = 24 t
18 t+ 18/36 = 24 t
6 t = 1/2
T = 1/12 hour = 5 minutes

Figure b is a scale image of Figure A, as shown. Figure a is an Rectangle with 9 on left side and 12 on bottom of rectangle. and

Ronch [10]

The scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.

<h3>How to Find the Scale Factor of a Dilation?</h3>

The ratio of the corresponding dimensions of the image to the preimage gives the scale factor of any dilation.

That is:

Scale factor = dimension of image (new figure) / corresponding dimension of pre-image (original figure).

The scale factor that was applied to figure A to produce figure B = dimension of figure B / corresponding dimension of figure A.

A dimension of figure B = 33

Corresponding dimension of figure A = 9

Therefore, we would find the scale factor as shown below:

The scale factor that was applied to figure A to produce figure B = 33/9

= 11/3 = 3.67

Therefore, the scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.

7. Five swimmers entered a competition. Four of the swimmers had their turns. Their scores are 9.8, 9.75, 9.79 and 9.81 seconds

arsen [322]

Answer:

We must order these decimals from least to greatest. Then we must determine how the least compares with the winning score.

9.80 -> 3

9.75 -> 1

9.79 -> 2

9.81 -> 4

The least decimal is 9.75. Now we must determine how 9.75 compare with the winning score.

The last swimmer must get a score less than 9.75 seconds in order to win.

Blababa [14]

Answer:

The Coordinates of Point C are C(5,2)

The slope of CD is 3

The possible coordinates of point D(a,b) are (6, 5) and (4, -1)

Step-by-step explanation:

According to the Question,

Given, The end points of AB are A(2,3) and B(8,1). The perpendicular Bisector of AB is CD, and point C lies on AB. The length of the CD is √10 units.

Now, Let The Coordinates of Point C are C( x , y ) .

Thus, C( x , y ) = ((8 +2) / 2 , ( 1 + 3 )/ 2 ) ⇒ (10/2 , 4/2) ⇒ (5 , 2)

The Coordinates of Point C are C( x , y ) ⇒C(5, 2).

And, The slope of AB = (1 - 3)/(8 - 2) ⇒ -2/6 ⇔ -1/3 .

Thus, The slope of CD is -1/(The slope of AB) = -1/(-1/3) ⇔ 3.

Let the coordinate of D be (a, b) then

⇒ √{ (b - 2)² +(a - 5)² } = √10

on squaring both sides we get,

⇒ a² - 10a + 25 + b² - 4b + 4 = 10

⇒ a² + b² - 10a - 4b = - 19 ⇔⇔ (Equation 1)

We Know, the slope of CD = 3

⇒Thus, (b - 2)/(a - 5) = 3

⇒ b - 2 = 3a - 15

⇒ b = 3a - 13 ⇔⇔ (Equation 2)

Putting value of Equation 2 into Equation 1, We get

⇒a² + (3a - 13)² - 10a - 4(3a - 13) = - 19

⇒a² + 9a² - 78a + 169 - 10a - 12a + 52 = - 19

⇒10a² - 100a + 240 = 0

⇒a² - 10a + 24 = 0

⇒(a - 4)(a - 6) = 0

⇒a = 4 or a = 6

Now,

When a = 4 , b = 3(4) - 13 ⇒ 12 - 13 ⇒ b = -1

When a = 6, b = 3(6) - 13 ⇒ 18 - 13 ⇒ b = 5

Therefore, the possible coordinates of point D(a,b) are (6, 5) and (4, -1).
