Because the angles on the first quadrant of the bottom horizontal line are equal, we conclude that the two parallel lines are FM and GB,
Which lines are parallel?
We know that two lines are parallel if when intersected by the same line, the two give the same angles.
In the image, we can see only one pair of equal angles, which are the two ones represented by a red quarter circle.
Both of these angles are on line MB, this means that the two parallel lines are the ones that intersect MB (in this case are the two vertical lines).

Initially, there were only 4 weeds at a park. The weeds grew at a rate of 15% each week. The following function represents the weekly weed growth: f(x) = 4(1.15)x. Rewrite the function to show how quickly the weeds grow each day and calculate this rate as a percentage.
f(x) = 4(1.15)7x; spreads at a rate of approximately 1.5% daily
f(x) = 4(1.02)7x; spreads at a rate of approximately 2% daily
f(x) = 4(1.157)x; spreads at a rate of approximately 2.66% daily
f(x) = 4(1.02)x; spreads at a rate of approximately 0.2% daily
Answers
The function to show how quickly the weeds grow each day is "f(x) = 4(1.02)7x; spreads at a rate of approximately 2% daily. Option B
How can we figure out the rate of increase in percentage terms each day?f(x) = 4(1.15)x = 4(1+ 0.15)x ................... (1)
Given that there are seven days in a week, the daily growth rate of the weeds may be estimated using equation (1) by dividing 0.15 (which stands for the 15% weekly growth rate) in the following manner:
f(x) = 4(1.15)x = 4(1+ 0.15/7)x
f(x) = 4(1 + 0.02)x
f(x) = 4(1.02)x
Since 0.02 is the same as 2%, this implies that the rate at which the weeds grow each day is 2%.

Johnson buys a newspaper each day.the cost of the newspaper is $1 per day except sunday.on sunday it cost $3. how much johnson spend on newspapers in 52 weeks.
Answers
By using the Unitary method, $468 was spent on newspapers in 52 weeks.
Unitary method is a method used for finding the unit cost in which we divide the total cost by the total number of articles and to find the cost of more than one article, we multiply the unit cost by the number of articles required.
Cost of newspapers in a week from monday to saturday = $(1 x 6) = $6
Cost of newspaper only on sunday of a week = $3
Cost of newspapers in a week = $(6 + 3) = $9
Therefore, the cost of newspapers in 52 weeks = $(52 x 9) = $468.

If the supplement of an angle is 12 degrees less than twice the measure of the angle, what is the measure of the angle?
Answers
The angle whose supplement is 12 degrees less than twice its measure is 64 degrees.
What is the measures of the supplementary angle?supplementary angles are angles that add up 180 degrees.
Given the data in the question;
Let x represent the first angle.
Measure of first angle = xMeasure of second angle = 2x - 12Numerical measures of the angles = ?Since the angle are supplementary, sum of angles = 180°
First angle + second angle = 180
x + ( 2x - 12 ) = 180
Solve for x

3x - 12 = 180
3x = 180 + 12

Answer:

Step-by-step explanation:
In this picture we can see that they gave us 2 angles.
Angle V has an angle of x+83
Angle S has an angle of 4x - 53
As one of the circle thermoses in mathematics said when there is an angle in the center of the circle, the angle at the circumference is half the angle at the center, which means we could create and equation such that:
angle of angle V = 2 times the angle of angle S
x + 83 = 2(4x - 53)
x + 83 = 8x - 106
189 = 7x
27 = x
Since we know x = 27, we can substitute into the equation angle of S to find what is the angle of TSU:
4x - 53
= 4(27) - 53
= 108 - 53
= 45
Answer:
<TSU = 55°
Step-by-step explanation:
We know that,
Angle at the circumference of a circle is twice the angle at the centre.
Therefore,
2 × <UST = <UVT
Given that,
< UVT = x + 83
< TSU = 4x - 53
Accordingly, we can make an expression like this.
[tex] \sf2 × <UST = <UVT[/tex]
[tex] \sf2(4x - 53) = x + 83 \\ [/tex]
And now solve the above expression and find the value of x.
Let us solve it now.
[tex] \sf8x - 106 = x + 83 \\ \sf8x - x = 106 + 83 \\ \sf7x = 189 \\ \sf \: x = 27[/tex]
And now, according to the question they've asked us to find the value of <TSU.
As we mentioned earlier, they've given that, <TSU = 4x - 53.
So, to find the value of Angle TSU, we have to replace x with 27 and find the value of angle TSU.
Let us solve it now
[tex] \sf \: <TSU = 4x - 53 \\ \sf \: <TSU = 4 \times 27 - 53 \\ \sf \: <TSU = 108 - 53 \\ \sf \: <TSU = 55 \degree[/tex]

Percentages show the proportional relationship between two fractions, like proportions and ratios.
The amount of the tip = $5
The cost of the ride = $25
The total amount paid by Serena's father = $30 ($5 + $25)
The percentage of tip to the ride's cost = The amount of the tip divided by the cost of the ride.

Applying the slope formula, we have:
16. Slope = -9/4; Parallel slope = -9/4; Perpendicular slope = 4/9.
17. Slope = -4; Parallel slope = -4; Perpendicular slope = 1/4.
See explanation below for the rest answers.
How to Find the Slope of a Line?Slope of a line = change in y / change in x.
The slope of parallel lines are the same, while the slopes of two lines that are perpendicular to each other are negative reciprocals of each other, i.e. 1/a and -a can be the slopes of two lines that are perpendicular to each other.
In an equation given in slope-intercept form, y = mx + b, the slope is represented as "m".
16. Given, (3, 7) and (7, -2):
Slope (m) = (-2 - 7)/(7 - 3)
Slope = -9/4
Parallel slope = -9/4
Perpendicular slope = 4/9.
17. Given, y = -4x + 2,
Slope = -4
Parallel slope = -4
Perpendicular slope = 1/4.
18. Rewrite 5x - 2y = 8 in slope-intercept form:
-2y = -5x + 8
y = 5/2x - 4
Slope = 5/2
Parallel slope = 5/2
Perpendicular slope = -2/5.
19. Rewrite 4x + 3y = 2 in slope-intercept form:
3y = -4x + 2
y = -4/3x + 2/3
Slope (m) = -4/3
Substitute (a, b) = (2, -5), and m = -4/3 into y - b = m(x - a):
y - (-5)) = -4/3(x - 2)
y + 5 = -4/3(x - 2) [point-slope form]
20. Given, y = -5x + 2
Slope (m) = -5
Substitute (a, b) = (-4, -6), and m = -5 into y - b = m(x - a):
y - (-6) = -5(x - (-4))
y + 6 = -5(x + 4) [point-slope form]
21. Rewrite 9x - 3y = 6 in slope-intercept form:
-3y = -9x + 6
y = 3x - 2
The slope of y = 3x - 2 (9x - 3y = 6) is 3.
The slope of -3x - 5 is -3.
Therefore, the lines are neither parallel nor perpendicular.
