C because first you would find the circumference of the circle which is pi times diameter, which is 18.84 but since it is a semi-circle you would divide by 2 which is 9.42. Then you do 3+3=6 + the length which is 6 so you get 12. 12+9.42=21.42 and if you round that to the nearest tenth it is 21.42.

Korey kept track of the number of miles he ran each week for five weeks. The median number of miles he ran during the five weeks

shepuryov [24]

Answer:

the correct answer would be A. the mean is when you add up all of them and divide it by how many numbers there are which in this case is 5. and the median is the number in the middle, in this case 20, therefore when you add up all numbers in A ,you get 105 and you divide it by 5 which gives you 21. :))

Given: ABC is similar to XYC. If BY = 6, YC = 10, AX = 18, then XC = 10.8 5 30 48

Sidana [21]

Answer:

The correct option is 3. The length of XC is 30.

Step-by-step explanation:

It is given that triangle ABC and triangle XYC are similar.

According to the properties of similar triangles, then corresponding sides of similar triangles are congruent.

In triangle ABC and triangle XYC,

$\frac{AB}{XY}=\frac{BC}{YC}=\frac{AC}{XC}$

Let the length of XC be x.

From the below figure it is notices that

$AC=AX+XC=18+x$

$BC=BY+YC=6+10=16$

$\frac{16}{10}=\frac{18+x}{x}$

$16x=180+10x$

$6x=180$

$x=30$

Therefore correct option is 3. The length of XC is 30.

A line goes through the point (6,-2) and has a slope of -3. What is the value of a if the point (a,7) lies on the line?

Vikki [24]

Answer:

<h2>a = 3</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question the slope is - 3

To find the value of a we have

$- 3 = \frac{7 - - 2}{a - 6} \\ - 3 = \frac{7 + 2}{a - 6} \\ - 3(a - 6) = 9 \\ - 3a + 18 = 9 \\ - 3a = 9 - 18 \\ - 3a = - 9$

Divide both sides by - 3

$\frac{ - 3a}{ - 3} = \frac{ - 9}{ - 3} \\$

We have the final answer as

<h3>a = 3</h3>

Hope this helps you
