Answer:
x = 6 , AC = [tex]\sqrt{89}[/tex]
Step-by-step explanation:
(3)
Tangents to a circle from an external point are congruent, then
4x - 9 = 15 ( add 9 to both sides )
4x = 24 ( divide both sides by 4 )
x = 6
(4)
the angle between a tangent and a radius at the point of contact is right , so
Δ ABC is a right triangle with hypotenuse AC
Using Pythagoras' identity in the right triangle
AC² = AB² + BC² = 5² + 8² = 25 + 64 = 89 ( square root both sides )
AC = [tex]\sqrt{89}[/tex] ≈ 9.4 ( to 1 dec. place )

Answer:
Measure of Arc JM = 160°
Step-by-step explanation:
We know that the sum of the measures of the angles within a circle all add up to 360°, so we can say:
(53) + (79) + (68) + (Arc JM) = 360
200 + Arc JM = 360
Arc JM = 360 - 200
Arc JM = 160
Hope this helps!
Answer:
mJM = 360 - (53 + 79 + 68)
mJM = 360 - 200
mJM = 160º
Given m||n, find the value of x.
kt
(7-10)
(6x-5)°
Answer:
15
Step-by-step explanation:
So, leets look at the graph.
We can see that the lines being solved for tecnically make up 180 degrees.
This is because the value of the angles on line m are equal to the value of the angles on line n.
So, we know that the total line, 180 degrees, is 7x-10, and 6x-5.
Lets combine these two equations, and subtract them from 180 degrees to solve for x:
7x-1+6x-5
=
13x-15
Now to solve for x:
13x-15=180
Add 15 to both sides to get 13x alone:
13x=195
Then divide both sides by 13 to get x alone:
x=15
So our value of x is 15!

A laundry basket contains 8 white t-shirts and 6 black t-shirts. What is the probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back?
Answer:
30/182 = 15/91.
Step-by-step explanation:
PROBABILITY: the likelihood of an event.
There are a total of 14 shirts in the basket.
Of the 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.
The probability of picking a black shirt is 6 in 14, or 6/14.
The probability of picking a white shirt is 8 in 14, or 8/14.
WITHOUT REPLACING: This means that you take one without putting it back. (There will be one less).
6/14 × 5/13 = 30/182.
30/182 = 15/91.
The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back is 15/ 91.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
There are a total 14 shirts in the basket.
Out of the total of 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.
The probability of picking a black shirt = 6/14.
The probability of picking a white shirt = 8/14.
The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back
= 6/14 × 5/13
= 30/182.
= 15/91.

Step-by-step explanation:
if you plug it in:
24-14=10
6+7=13
for the second one, if you have two minuses(6 - -7) you have to switch it to a plus sign (6+7)

Here is how you would solve this system of equations.
[tex]\begin{bmatrix}4x+2y=10\\ x-y=13\end{bmatrix}[/tex]
Step 1: Multiply x-y=13 by 4.
[tex]\begin{bmatrix}4x+2y=10\\ 4x-4y=52\end{bmatrix}[/tex]
Step 2: Subtract the equations.
[tex]4x-4y=52[/tex]
-
[tex]\underline{4x+2y=10}[/tex]
[tex]-6y=42[/tex]
[tex]\begin{bmatrix}4x+2y=10\\ -6y=42\end{bmatrix}[/tex]
Step 3: Solve -6y=42
[tex]y=-7[/tex]
For 4x+2y=10 plug in y=-7
[tex]4x+2(-7)=10[/tex]
Simplify.
[tex]4x-14=10\\4x-14+14=10+14\\4x=24\\x=6[/tex]
Therefore, x=6, y=-7.

Given
Represent each withe first letter of their name;
So:
[tex]C = 3H[/tex]
[tex]R = \frac{1}{2}H[/tex]
[tex]\frac{C + R + H}{3} = 15[/tex] --- the average of books
Required
The number of book each has
Substitute [tex]C = 3H[/tex], [tex]R = \frac{1}{2}H[/tex] in [tex]\frac{C + R + H}{3} = 15[/tex]
[tex]\frac{3H + \frac{1}{2}H + H}{3} = 15[/tex]
Multiply both sides by 3
[tex]3 * \frac{3H + \frac{1}{2}H + H}{3} = 15 * 3[/tex]
[tex]3H + \frac{1}{2}H + H = 45[/tex]
Take LCM and solve
[tex]\frac{6H + H + 2H}{2}= 45[/tex]
[tex]\frac{9H}{2}= 45[/tex]
Multiply both sides by 2/9
[tex]\frac{2}{9} * \frac{9H}{2}= 45 * \frac{2}{9}[/tex]
[tex]H= 45 * \frac{2}{9}[/tex]
[tex]H= 5 * 2[/tex]
[tex]H= 10[/tex]
[tex]C = 3H[/tex]
[tex]C = 3 * 10[/tex]
[tex]C = 30[/tex]
[tex]R = \frac{1}{2}H[/tex]
[tex]R = \frac{1}{2} * 10[/tex]
[tex]R = 5[/tex]

A box-and-whisker plot. The number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 17. A line divides the box at 15.
Answer:
its C
Step-by-step explanation:
The box plot which correctly displays the data set with the given values is A. The number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 19. A line divides the box at 15.
What is Box Plot?Box plot, which is also known as box and whisker plot, is a method of graphically representing the measures like minimum, maximum and the quartiles of the data set.
Here three box and whiskers plots are given.
We have to find the box plot where,
Maximum point = 24
Minimum point = 3
Median = 15
Upper quartile = 19
Lower quartile = 6
Here the range of the whiskers depicts the maximum and minimum point.
So, the whisker must range from 3 to 24.
The range of the box depicts the quartile range.
So box must range from 6 to 19.
A line will be dividing in between which depicts the median.
So the line must be at 15.
Hence the correct plot is the number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 19. A line divides the box at 15.

99 % of the trees in our neighborhood are eucalyptus trees. The town planning commission wants to get rid of some of these trees because they spread too quickly. However, the people in my neighborhood like the trees. The commission argues that their new eucalyptus tree removal plan will cut down so few eucalyptus trees that 98% of the trees in our neighborhood will be eucalyptus trees. If the plan only involves removing eucalyptus trees, what percent of the existing trees in my neighborhood would the plan remove
Answer:
50%
Step-by-step explanation:
Let the total number of trees be T and suppose that this is made up of eucalyptus trees E and other kinds of trees, O.
Then E+O=T, and since 99% of the trees are eucalyptus trees, EE+O=0.99.
Therefore
0.99E+0.99O=E
0.01E=0.99O
E=99O.
Suppose we reduce the number of eucalyptus trees by some amount x and that the remaining number of eucalyptus trees are now 98% of the total trees.
Then we would have E−x(E−x)+O=0.98.
Therefore,
0.02(E−x)=0.98O
0.02E−0.02x=0.98O
0.02x=0.02E−0.98O
x=E−50(0.98)O
x=E−49O
x=E−49(E99)
x=5099E≈0.505050...×E.
So we end up removing a little over half of the eucalyptus trees. EDIT: Forgot to mention - removing 50.505050...% of the eucalyptus trees means that we are removing 0.50505050....×0.99T which is 0.5T or half the trees in the neighborhood.
Given RU = 5x+2 and RS = 2x+5, find x.

According to the given graph, we see that our data is increasing. Therefore, there will be a positive relationship in the graph.
∴ Answers C and D are eliminated.
We also see that we can draw a best line of fit in the graph. Since we can approximate this data using a linear line, our answer choice would be B.
