1) In the diagram, l || m. If the measure of angle 3 is 120 find the measure of the following angles
a) angle 4
b) angle 6
c) angle 8
2)Describe the sequence of transformations from quadrilateral WXYZ to W” X” Y” Z”.
Answer:
i) angle 3 is 120°
ii) angle 3 + angle 4 = 180° as both angles make up a staright line
∴ angle 4 = 180° - angle 3 = 180° - 120° = 60°
iii) angle 6 = angle 3 = 120° as they are opposite interior angles
iv) angle 6 + angle 8 = 180° as both angles make up a straight line
∴ angle 8 = 180° - angle 6 = 180° - 120° = 60°
Step-by-step explanation:
i) angle 3 is 120°
ii) angle 3 + angle 4 = 180° as both angles make up a staright line
∴ angle 4 = 180° - angle 3 = 180° - 120° = 60°
iii) angle 6 = angle 3 = 120° as they are opposite interior angles
iv) angle 6 + angle 8 = 180° as both angles make up a straight line
∴ angle 8 = 180° - angle 6 = 180° - 120° = 60°
.There are 850 Douglas fir and Ponderosa pine trees in a section of forest bought by Karamazov Logging Co. The company paid an average of $300 for each Douglas fir and $225 for each Ponderosa pine. If the company paid $217,500 for the trees, how many of each kind did the company buy
The number of Douglas fir pine trees is 350, and the number of Ponderosa pine trees is 500
Applications of Simultaneous equationFrom the question, we are to determine the number of each kind of pine trees.
Let x represent Douglas fir pine trees
and y represent Ponderosa pine trees
From the first statement - There are 850 Douglas fir and Ponderosa pine trees
We can write that
x + y = 850 ------------- (1)
Also,
The company paid an average of $300 for each Douglas fir and $225 for each Ponderosa pine; and the company paid $217,500 for the trees.
From this statement, we can write that
300x + 225y = 217500 ---------------- (2)
Now, we will solve the equations simultaneously
From equation (1)
x + y = 850
Then,
x = 850 - y ------------ (3)
Substitute this into equation (2)
300x + 225y = 217500
300(850-y) + 225y = 217500
255000 -300y + 225y = 217500
255000 - 75y = 217500
255000 - 217500 = 75y
37500 = 75y
∴ y = 37500/75
y = 500
Substitute the value of y into equation (3)
x = 850 - y
x = 850 - 500
x = 350
∴ x = 350 and y = 500
Hence, the number of Douglas fir pine trees is 350, and the number of Ponderosa pine trees is 500

If the function m not-equals 0 has an inverse function, which statement must be true?
Note: Your question is missing some details. After a little research, I am able to find the complete question which is as follows:
If the function f(x) = mx + b has an inverse function, which statement must be true?
a) m=/0
b) m = 0
c) b=/0
d ) b = 0
Answer:
The value of [tex]m[/tex] cannot be equal to 0. In other words,
[tex]m\:\ne \:0[/tex]
Step-by-step explanation:
Considering the function
[tex]f(x) = mx + b[/tex]
Lets find the inverse of this function.
Suppose
[tex]y=f\left(x\right)[/tex][tex]y=mx+b[/tex]Lets exchange the variables [tex]x[/tex] and [tex]y[/tex] such as
[tex]x=my+b[/tex]
Lets isolate the variable [tex]y[/tex]
[tex]my=x-b[/tex]
[tex]y=\frac{x-b}{m}[/tex]
Suppose
[tex]f\left(x\right)^{-1}=y[/tex]
As
[tex]y=\frac{x-b}{m}[/tex]
So, inverse function is
[tex]f\left(x\right)^{-1}=\frac{x-b}{m}[/tex]
As the denominator [tex]m[/tex] cannot be zero in the inverse function.
Thus, the value of [tex]m[/tex] cannot be equal to 0. In other words,

Allen and Beverly thought of the same number. Allen doubled the number and added 15 to the result. He got 51. Beverly performed the same operations with the number, but in reverse order. What did she get?
Allen and Beverly both thought of the number 18. When Allen doubled the number and added 15, he got 51. Beverly, in reverse order, subtracted 15 from the number and then doubled it to get 6.
Let the number that Allen and Beverly thought of be represented by 'x'.
Allen doubled the number and added 15 to the result, which gives us the equation:2x + 15 = 51
Now, we need to solve for 'x' to find the original number.
Subtract 15 from both sides of the equation: 2x = 51 - 15
2x = 36
Now, divide both sides by 2 to isolate 'x': x = 36 / 2
x = 18
So, Allen and Beverly both thought of the number 18.
Now, Beverly performs the same operations but in reverse order: 1. She starts with the number 18.
2. She subtracts 15 from it:18 - 15 = 3
3. Then, she doubles the result:2 * 3 = 6
So, Beverly gets the result of 6 by performing the same operations in reverse order.

Lee sold 60 magazine
Step-by-step explanation:
Terrence and Lee were selling magazines for a charity
In the first week, Terrance sold 30% more than LeeIn the second week, Terrance sold 12 magazines, but Lee did not sell anyTerrance sold 50% more than Lee by the end of the second weekWe need to find how many magazines Lee sold
Assume that Lee sold x magazines
∵ Terrance sold 30% more than Lee in the first week
∵ Lee sold x magazines in the first week
- Find 30% of x and add it to x to find how many magazines
Terrance sold
∵ Terrance sold = 30% × x + x
∴ Terrance sold = [tex]\frac{30}{100}[/tex] × x + x = 0.3 x + x
∴ Terrance sold = 1.3 x magazines in the first week
∵ Terrance sold 12 magazines in the second week
- Add 1.3 x to 12 to find the number of magazines that Terrence
sold in the two weeks
∴ Terrence sold 1.3 x + 12 magazines in the two weeks
∵ Lee did not sell any in the next week
∴ Lee sold x magazines in the two weeks
∵ Terrance sold 50% more than Lee by the end of the 2nd week
- Equate 1.3 x + 12 by the sum of x and 50% of x
∴ 1.3 x + 12 = 50% × x + x
∵ 50% × x = [tex]\frac{50}{100}[/tex] × x = 0.5 x
∴ 1.3 x + 12 = 0.5 x + x
- Add the like terms in the right hand side
∴ 1.3 x + 12 = 1.5 x
- Subtract 1.3 x from both sides
∴ 12 = 0.2 x
- Divide both sides by 0.2
∴ 60 = x

Archimedes went to sleep beside a big rock. He wanted to get up at 777 AM, but the alarm clock was yet to be invented! He decided to sleep at the spot where the rock's shadow should end when it's 777 AM so as to be awakened by the direct sunlight.
Archimedes knew that at 777 AM, the sunlight reaches the ground at an angle of 31^\circ31
∘
31, degrees. The rock beside which he slept was 555 meters tall.
How far from the rock did Archimedes go to sleep?
By using the tangent function tan(31°) = opposite/adjacent, and knowing the rock's height of 555 meters, we can find the distance from the rock that Archimedes should sleep to wake up with direct sunlight. The distance is calculated as the height of the rock divided by the tangent of the angle of the sun, which will give the desired result.
Explanation:To find out how far from the rock Archimedes went to sleep, we can use the concept of trigonometry. Specifically, we will use the tangent function, which relates the angle of the sun to the height of the rock and the distance of the shadow on the ground.
Given that the sunshine angle is 31 degrees and the rock is 555 meters tall, we can set up our equation using the tangent function: tan(31°) = opposite/adjacent, where the opposite side is the height of the rock, and the adjacent side is the distance from the rock where Archimedes slept.
The equation would look like this:
tan(31°) = 555 / distance
To solve for the distance, we rearrange the equation:
distance = 555 / tan(31°)
By calculating this, we would get the distance where Archimedes should sleep to be woken by the direct sunlight.
Danica is in the observation area of the sears tower in chicago overlooking lake michigan. She sights two sailboats going due east from the tower. The angles of depression to the two boats are 42 degrees and 29 degrees. If the observation deck is 1,353 feet high, how far apart are the boats?
The distance between the two sailboats is approximately 2,197 feet.
1. Find Distances to Boats:
- Use the tangent function for each angle of depression to find the distances from the observation deck to each sailboat. For boat 1 (42 degrees), use [tex]\(\tan(42^\circ) = \frac{\text{height}}{\text{distance}}\)[/tex], and for boat 2 (29 degrees), use [tex]\(\tan(29^\circ) = \frac{\text{height}}{\text{distance}}\)[/tex].
2. **Calculate Individual Distances:**
- For Boat 1: [tex]\( \text{Distance}_{\text{Boat 1}} = \frac{\text{height}}{\tan(42^\circ)} \)[/tex]
- For Boat 2: [tex]\( \text{Distance}_{\text{Boat 2}} = \frac{\text{height}}{\tan(29^\circ)} \)[/tex]
3. Determine Distance Between Boats:
- The distance between the two boats is [tex]\( \text{Distance}_{\text{Boat 1}} - \text{Distance}_{\text{Boat 2}} \)[/tex].
4. Final Answer:
- The final answer is the distance between the two sailboats, which is approximately 2,197 feet.

What is the slope Intercept form of 8x-2y=-72
Answer:
y = 4x + 36
Step-by-step explanation:
To find the equation in slope-intercept form, rearrange to isolate "y".
Slope-intercept form is y = mx + b. The variables mean:
"x" and "y" - points that are on the line, or solutions.
"m" - the slope, how steep the line is
"b" - the y-intercept, when the line touches the y-axis
Isolate "y".
8x - 2y = -72
8x - 8x - 2y = -72 - 8x Subtract 8x from both sides.
-2y = -72 - 8x Left side : 8x - 8x = 0
[tex]\frac{-2}{-2}y = \frac{-72}{-2} - \frac{8}{-2}x[/tex] Divide both sides by -2
y = 36 - (-4)x Simplify the fractions
y = 36 + 4x Remember two negatives make a positive, add 4x.
y = 4x + 36 Put "4x" in front of 36. It looks like y = mx + b now.
"m" would be 4.
"b" would be 36.
-12.11x - 10.5 = 75.6 - 3.5x
Answer:
x = −10
Step-by-step explanation:
1. Add 12.11x to both sides.
−10.5 = 75.6 − 3.5x + 12.11x
2. Simplify 75.6 - 3.5x + 12.11x to 75.6 + 8.61x.
−10.5 = 75.6 + 8.61x
3. Subtract 75.6 from both sides.
−10.5 − 75.6 = 8.61x
4. Simplify −10.5 −75.6 to −86.1.
−86.1 = 8.61x
5. Divide both sides by 8.61.
[tex]-\frac{8.61}{86.1}[/tex] = x
6. Simply [tex]-\frac{8.61}{86.1}[/tex] to 10
−10 = x
7. Flip it.
x = −10
