Determine the value of x. Assume the segments that appear tangent
are tangent
9514 1404 393
Answer:
x = 12
Step-by-step explanation:
Segment lengths of each chord have the same product.
(x -2)(x +6) = 9×20
x² +4x -12 = 180
x² +4x +4 = 196 . . . . . add 16 (complete the square)
(x +2)² = 14²
x +2 = 14 . . . . . . . . . . . positive root is the only one useful
x = 12

4x-3x+9=20
Answer:
This can be solved like this:
4x-3x+9=20
Solving 4x-3x
x+9=20
Transposing +9
x=20-9
And now we have, x=11
Answer:
x=11
Step-by-step explanation:
first solve the things you can simplify on one side of the equation:
4x-3x+9=20--->x+9=20
then, get the variables onto one side of the equation and numbers unto the other.
*minus 9 from each side*
x=11

Step-by-step explanation:
Juan has 240 marbles. This is three times as many marbles as Jon and Jeremy have combined. If Jon has 50 marbles, how many marbles does Jeremy have?
Answer:
30
Step-by-step explanation:
Let x = number of marbles Jon has
y = number of marbles Jeremy have
3(X + Y) = 240
3(50 + Y) = 240
Divide both sides by 3
50 + Y = 80
Solve for y
Y = 30

Write the equations of the line that passes through the point (4,3) and is parallel to the line y=2x−4 . Write the equation in slope-intercept form
Answer:
y=2x+5
Step-by-step explanation:
I used 2 as the slope bc we were given an equation above: y=2x-4. Since parallel lines have same slopes and different y-intercepts, hence, I easily got 2 as the slope.

This question has a slope of zero.
Step-by-step explanation:
When trying to solve a problem like this, what I recommend doing is subtracting the y value in the first ordered pair from the y value in the second ordered pair, and doing the same for the x values. To write it as a formula,
y2 - y1
––––– = m the 2 in the formula means that the y or x value was from the
x2 - x1 second ordered pair. The 1 means it was from the first
ordered pair. The m means slope.

Elias had 3 time as much money as munah.Elias spent $240 and munah received $60 from her brother. In the end.Elias and munah had the same amount of money.How much did elias have at first
Answer:
$450
Step-by-step explanation:
let m represent the amount of money munah has
That means elias would have 3 * m or 3m dollars.
Then, you have m + 60 = 3m - 240
solve:
[tex]m + 60 = 3m -240\\300 = 2m\\m = 150[/tex]
So munah started with $150. Since elias has 3 times as much, they have 150 * 3 = 450

A hiking trail rises 6 feet for every horizontal change of 100 feet. What is the slope of the hiking trail?
Given:
A hiking trail rises 6 feet for every horizontal change of 100 feet.
To find:
The slope of the hiking trail.
Solution:
We have,
Rise = 6 ft
Run = 100 ft
We know that
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{6}{100}[/tex]
[tex]Slope=0.06[/tex]
Therefore, the slope of the hiking trail is 0.06.
The slope of the hiking trail is equal to 0.06.
Given the following data:
Vertical distance (rise) = 6 feetHorizontal distance (running) = 100 feetTo find the slope of the hiking trail, we would use the following formula:
Slope is the ratio of the vertical distance measured to the horizontal distance measured.
Mathematically, the slope of a hiking trail is given by the formula:
[tex]Slope = \frac{Rise}{Running}[/tex]
Where:
V is the rising vertical distance of an object.H is the horizontal distance an object runs through.Substituting the given parameters into the formula, we have;
[tex]Slope = \frac{6}{100}[/tex]
Slope = 0.06

180 - 81 = 99 degrees
Answer:
99 degrees
Step-by-step explanation:
These are Supplementary Angles:
Supplementary Angles are two angles that equal 180 degrees, this can be determine if the main line is a straight line, s for straight angle
A straight angle is 180 degrees, so simple subtraction:

Answer:
Other needs =25,2 degrees
insurance = 100,8 degrees
Taxes= 7,2
Housing = 57,6
food= 57,6
childcare = 64,8
transportation = 46,8
Step-by-step explanation:
Its % of 360 degrees so you have to calculate the percentage of each categorie on 360 degrees to find the angles. Exemple, for the Other needs, you take 7% out of 360 degrees and you find that it is equal to 25,2. (7% x360 degrees /100)
In a regular polygon each interior angle is 140° greater than each exterior angle. Calculate the number of sides of the polygon
Answer:
18 sides.
Step-by-step explanation:
The interior and exterior angles sum to 180 so:
I + E = 180
also I - E = 140 (given)
So, adding to eliminate E:
2I = 320
I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.
Since the sum of all exterior angles in a polygon = 360 degrees
- the number of sides = 360 / 20 = 18.

Answer:
Please rate as brainliest.
Step-by-step explanation:
The Moon exerts its force of gravity; since it's smaller and lighter than Earth, we would discover we weigh around a sixth of our weight on Earth if we could weigh ourselves on it. One could ask why the Moon doesn't fall on Earth as an apple from the tree.
