Scala factors are used to compress or enlarge an image.

The actual length and width of the basketball court are 84 feet and 25 feet, respectively.

<h3>How to determine the actual length and width</h3>

From the question, the scale measurements are:

Length = 10.5 feet

Width = 6.25 feet

Given that the scale factor is 8.

The actual dimensions are the product of the scale dimensions by 8.

So, we have:

Actual length = 10.5 feet * 8 = 84 feet

Width = 6.25 feet * 4 = 25 feet

Hence, the actual length and width of the basketball court are 84 feet and 25 feet, respectively.

What is the length of the line segment with end points (5, -7) and (5, 11)

Law Incorporation [45]

Answer:

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (5, -7) and (5, 11). Substitute:

$d=\sqrt{(5-5)^2+(11-(-7))^2}=\sqrt{0^2+18^2}=\sqrt{18^2}=18$

Monica took a survey of her classmates' hair and eye color. The results are in the table below.

jolli1 [7]

Answer:

let R represent red hair

let G represent green eyes

<em>from</em><em> </em><em>Baye's</em><em> </em><em>theorem</em><em>:</em>

P(RnG) = 5

$P(G) = { \sum}(green \: hair) \\ = (3 + 5 + 5) \\ = 13$

Therefore:

$P( \frac{R}{G} ) = \frac{5}{13} \\ = 0.385$

The conditional relative frequency = 0.385

Six students eat 6 apples in 33 seconds. How long will it take nine students to eat 19 apples, if they don't cut apples into par

stepladder [879]

Answer: 104.5 seconds

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

Six students eat 6 apples in 33 seconds.

The proportion is: number of apples eaten /time

6 apples /33 seconds = 6/33

For 19 apples:

19 apples / x seconds =19/x

6/33 = 19/x

Solving for x:

x = 19 / ( 6/33)

x = 104.5 seconds
