in the figure, p||q. On a recent math test, Jacob incorrectly listed the value of w as 101.
Find the value of w.
What mistake did Jacob likely make?
Answer:
x = 79
Step-by-step explanation:
Part A:
It's stated that line p and line q are parallel, if it is so then the angle represented with w and the angle with measure 79 are alternate and their measure is equal to each other:
Part B:
Jacob likely thought angle represented with W and the angle with the measure 101 are alternate so he made a mistake and found wrong result.

This is false, the angles are supplementary, not corresponding.This is true.This is true.This is true, angles 1 and 5 are congruent (corresponding), and angles 5 and 7 are supplementary. Hence, angles 1 and 7 are also supplementary.This is true (same-side interior angles)Question 3 of 10
Which equation represents the slope-intercept form of the line below
Answer:
[tex]y = \frac{1}{2}x + 8[/tex]
Step-by-step explanation:
The general slope-intercept equation is: y = mx + b.
In this equation, "m" is equal to the slope and "b" is equal to the y-intercept.
Since the slope is "1/2", then this is the "m" value.
Since the line passes the y-axis at "8" when x = 0, then "b" must be "8".
Therefore, the equation of the function in slope-intercept form is [tex]y = \frac{1}{2}x + 8[/tex].
HELP!!! THESE ARE DO TODAY
Answer:
72
Step-by-step explanation:
First, we should probably break this shape down into 2 easier to work with shapes. The dimensions of these will be 4*9 and 6*6. I get 6 because when you break 4*9 off, you're also taking 4 off from the 10, giving you 6. Now just multiply and then add the area of both shapes. 4*9=36, and 6*6=36. 36+36=72, so that's your answer.
Hope this helps!

In the diagram, A||B and B||C. Find the values of X.
Answer:
31
Step-by-step explanation:
3x + 12 and 105 are alternate exterior angles because A || B and B || C.
If the two or more lines are parallel, then the alternate exterior angles are equal.
3x + 12 = 105
Substract 12 on both sides,
3x = 105 - 12
3x = 93
Divide 3 on both sides,
x = 93 / 3
x = 31

How many quarts of a 50% acid solution must be added to 20 quarts of a 20% acid
solution to obtain a 40% acid solution?
Answer:
40 quarts
Step-by-step explanation:
The amount of additional 50% acid solution can be found by writing an equation for the amount of acid in the mix.
__
Let x represent the number of quarts of 50% acid solution that need to be added. The total number of quarts of acid in the 40% mix is ...
0.50x +0.20(20) = 0.40(x +20)
0.10x = 0.20(20) . . . . . . . subtract 0.40x +0.20(20)
x = 40 . . . . . . . . . . . . divide by 0.10
40 quarts of 50% solution must be added.
_____
Additional comment
That will make a total of 60 quarts of solution, of which 24 quarts (40%) are acid.
Step-by-step explanation:
while the other answer is correct, let me try to explain this in a different optical way :
50% means 50/100 = 1/2 = 5/10 of the substance is acid.
20% means 20/100 = 1/5 = 2/10 of the substance is acid.
40% means 40/100 = 2/5 = 4/10 of the substance is acid.
now, we want to find the quantity of x quarts that satisfies the desired balance :
x × 50% + 20 × 20% = (x + 20) × 40%
x × 5/10 + 20 × 2/10 = (x + 20) × 4/10
5x/10 + 4 = 4x/10 + 8
x/10 = 4
x = 40
so, yes, we need to add 40 quarts of the 50% solution.
that gives us 60 quarts, with 40% = 40/100 = 4/10 = 2/5 = being acid : 60 × 2/5 = 120/5 = 24 quarts
Find the equation of a line that passes through the points (2,5) and (2,12)
We know the following:
[tex]\text{Slope formula} = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Note: Slopes can only be determined if the lines are not vertical.
Since the x-coordinate of the points that pass through the line are the same, when the points are substituted in the slope formula, the slope will result in "undefined" (Work shown below).
[tex]\text{Slope formula} = \dfrac{12 - 5}{2 - 2}[/tex]
[tex]\text{Slope formula} = \dfrac{7}{0} = \text{unde}\text{fined} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{Any non-number divided by 0 is unde}\text{fined}][/tex]
Now, let's see if the vertical line will intersect the x-axis or a y-axis.
Determining if the line will intersect the x or y-axisTo determine if the vertical line will intersect the x or y-axis, we must look for the intersection of the line on the x or y-axis. The vertical line will be parallel to the y-axis and will intersect the x-axis.
Therefore, the line will intersect the x-axis.
Replacing values in an equation:Since the line does not intersect the y-axis, the equation of the line on the left-hand side will have an x-variable.
⇒ x = ?
The x-intercept will be substituted on the right-hand side of the equation. Since the line that passes through the two points [(2,5) and (2,12)] have the "2" as their x-coordinates, the x-intercept will also be 2. Therefore,
⇒ x = 2

Identify the coordinates of four points on the line with each given slope and y-intercept. slope = 2/3 and y-intercept = -5
PLEASE ANSWER
The coordinates of four points on the line are (0,-5), (3,-3), (6,-1) and (9,1)
How to determine the coordinates?The given parameters are given as:
Slope, m = 2/3y-intercept, c = -5The equation is represented as:
y = mx + c
So, we have:
y = 2/3x -5
When x = 0, we have;
y = 2/3 * 0 -5 = -5
When x = 3, we have;
y = 2/3 * 3 -5 = -3
When x = 6, we have;
y = 2/3 * 6 -5 = -1
When x = 9, we have;
y = 2/3 * 9 -5 = 1
Hence, the coordinates of four points on the line are (0,-5), (3,-3), (6,-1) and (9,1)

A polygon A prime B prime C prime D prime has A prime at ordered pair negative 3, 3, B prime at ordered pair negative 5, 4, C prime at ordered pair negative 4, 1, D prime at ordered pair negative 3, 1.

Counterclockwise rotation by 90 degrees about the origin followed by a translation to the right by 2 units
Counterclockwise rotation by 90 degrees about the origin followed by a translation to the left by 2 units
Answer:
Reflection over the y-axis followed by a translation to the left by 2 units
Step-by-step explanation:
From inspection of the graph, the y-values of figure ABCD and the y-values of figure A'B'C'D' have not changed, yet the x-values have changed from positive to negative.
(x, y) → (-x, y)
This indicates a reflection in the y-axis.
To reflect figure ABCD in the y-axis, simply change the x-values to negative:
A (1, 3) → (-1, 3)
B (3, 4) → (-3, 4)
C (2, 1) → (-2, 1)
D (1, 1) → ( -1, 1)
Comparing the x-values of the figure reflected in the y-axis to the x-values of the final translated figure, the reflected figure needs to be translated to the left by 2 units.
So the total transformation is: (x, y) → (-x - 2, y)
A (1, 3) → A' (-3, 3)
B (3, 4) → B' (-5, 4)
C (2, 1) → C' (-4, 1)
D (1, 1) → D' ( -3, 1)

To approximate the square root of 13:
Working from the top down...
Enter the number you are trying to approximate in the top box: [tex]\boxed{\sf \sqrt{13}}[/tex]
Find the perfect squares directly below and above 13.
Perfect squares: 1, 4, 9, 16, 25, 36, ...
Therefore, the perfect squares below and above 13 are: 9 and 16
Enter these with square root signs in the next two boxes: [tex]\boxed{\sf \sqrt{9}}[/tex] and [tex]\boxed{\sf \sqrt{16}}[/tex]
Carry out the operation and enter [tex]\boxed{\sf 3}[/tex] and [tex]\boxed{\sf 4}[/tex] in the next two boxes.
Enter the number you are trying to square root (13) in the top left box, the perfect square above it (16) in the box below, then the perfect square below it (9) in the two boxes to the right of these. Carry out the subtractions and place the numbers in the boxes to the right.
[tex]\dfrac{\boxed{\sf 13}-\boxed{\sf 9}}{\boxed{\sf 16}-\boxed{\sf 9}}=\dfrac{\boxed{\sf 4}}{\boxed{\sf 7}}[/tex]
Now enter the number you are trying to square root (13) under the square root sign. Place the square root of the perfect square below it (3) in the box to the right. Copy the fraction from above (4/7). Finally, enter this mixed number into a calculator and round to the nearest hundredth.

The percent of the purchase price for Julio’s down payment was C. 18%
What is Interest Rate?This refers to the amount of money that is added to a loan collected by a person, for when he makes repayment.
Hence,
Given that
PMT monthly payment 1558.09R interest rate 0.05875K compounded monthly 12 because the payment is monthlyN time 20 yearsPv present value?We use the formula Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv= 1,558.09×((1−(1+0.05875÷12)^(−12×20))÷(0.05875÷12))
=219,684.92
Next thing to do is make a subtraction to get the down payment:
267,900−219,684.92=48,215.08
