Answer:
C) y = 16 feet
Step-by-step explanation:
the corresponding sides in ABCD are equal to their corresponding sides by EFGH multiplied by something
all values are in feet
let x represent the unknown side in ABCD
ABCD lengths in order: x, 30 , 40 , 60
let a and b represent the unknown sides in EFGH
EFGH lengths in order: 6, 12, a, b
thus, 30 corresponds to 12 as they are both the second shortest sides
corresponding side in EFGH * something = corresponding side in ABCD
12 * something = 30
let something be r
12 * r = 30
divide both sides by 12 to isolate r
r = 30/12
thus, to get a side in ABCD, we multiply the corresponding side in EFGH by 30/12
we want to find the second longest side in EFGH. the corresponding side to that in ABCD is 40, as 40 is the second longest side in ABCD
let the second longest side in EFGH = y
y * 30/12 = 40
multiply both sides by 12/30 to isolate y
40 * 12 / 30 = y = 16
y = 16 feet

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.

A motorcycle that regularly sells for 1,450 was discounted by 40% off
Answer:
$870.00 is the motorcycle price after a 40% discount
Step-by-step explanation:
discount = original price x discount % / 100
discount = 1450 x 40 / 100
discount = 1450 x 0.4
discount = $580.00
Final Price = Original Price - Discount
Final Price = 1450 - 580

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.

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

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

The mean can be calculated by determining the sum of the chosen pumpkins and dividing it by the total pumpkins chosen for the photograph.
Sum of the chosen pumpkins: 18 + 22 + 14 + 30 + 26Total pumpkins chosen: 5 pumpkinsTherefore, the fraction that represents the mean is:
[tex]\dfrac{18 + 22 + 14 + 30 + 26}{5}[/tex]
When we simplify the fraction, we get:
[tex]\implies \dfrac{18 + 22 + 14 + 30 + 26}{5}[/tex]
[tex]\implies \dfrac{40 + 14 + 30 + 26}{5}[/tex]

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

The north is opposite to the south
So the vector [tex]j[/tex] represents 1 mile per hour south.
Maria is jogging south at 12 miles per hour.
Therefore, the vectors [tex]12j[/tex] represents Maria's velocity. The correct answer is B.
The vector used to represent the position of Maria is -12j.
What is Vector?A measurement with a magnitude and direction. It is often represented by an arrow whose length is proportional to the magnitude of the quantity and whose direction is the same as that of the quantity. A vector does not have position, while having magnitude and direction.

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].
