Watch help video Given mn, find the value of x. (6x-3)⁰ (2x+13)°
Answer:
x = 4
Step-by-step explanation:
(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.
(6x - 3)° = (2x + 13)°
6x - 2x = 13 + 3
4x = 16
x = 4
Substitute x for the angles.
(6x - 3)° = ?
(6*4 - 3)° = ?
(24 - 3)° = 21°
(2x + 13)° = ?
(2*4 + 13)° = ?
(8 + 13)° = 21°

The box-and-whisker plot below represents some data set. What percentage of the
data values are between 90 and 110?
HELP
Answer:
25 percent; each section of the box plot counts as 25%
The value of percentage of the data values are between 90 and 110 is,
⇒ 50%
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The box-and-whisker plot below represents some data set.
Now, We get;
Range of data set = 130 - 90
= 40
Hence, The value of percentage of the data values are between 90 and 110 is,
⇒ (110 - 90)/40 x 100
⇒ 20/40 x 100
⇒ 50%
Thus, The value of percentage of the data values are between 90 and 110 is,
⇒ 50%

Austin rented a truck for one day. There was a base fee of 14.95 and there was an additional charge of 95 cents for each mile driven. Austin had to pay 130.85 when he returned the truck. For how many miles did he drive the truck
Answer:
122 miles
Step-by-step explanation:
Let n = number of miles driven
Given:
Base fee = $14.95Charge per mile = $0.95Total cost = $130.85⇒ 14.95 + 0.95n = 130.85
Subtract 14.95 from both sides:
⇒ 0.95n = 115.90
Divide both sides by 0.95
⇒ n = 122
Therefore, he drove 122 miles.
Solve the equation. Write your answer as an integer or simplified fraction.

What are the vertex, focus, and directrix of the parabola whose equation is y-5= 1/12 (x-3)^2
Answer:
Vertex: (3,5)
Focus: (3,8)
Directrix: y = 2
Step-by-step explanation:
Get y by itself by adding 5 over to the other side. The equation is now y = 1/12(x-3)^2 + 5.
The value inside of the parentheses is -3. Since it's within the parentheses, switch the signs for the x value of the vertex. The "+ 5" represents the y value. Therefore the vertex is (3,5).
The value "a" on the parabola is 1/12. To find the distance from the vertex to the focus/directrix, use the equation a = 1/4p. 1/12 = 1/4p. p = 3. This parabola opens up, so "p" must be added onto the y value of the vertex for the focus. The focus is therefore (3,8).
For the directrix, subtract "p" from the y value of the vertex. The directrix is a horizontal line at y = 2.
