Answer:
y=-1/3x +29/3
Step-by-step explanation
We know that the line perpendicular to a slope of 3 is it's opposite reciprocal. So the slope is -1/3. Substitute -5 as X and 8 as Y so you get:
8= -5/3x +b.
B= 29/3
That's your answer.

If 108 people attend a concert and tickets for adults cost $4 while tickets for children cost $2 and total receipts for the concert was $328, how many of each went to the concert?
Answer method 1
81 adults and 2 child.
Answer method 2
Therefore 69 adults came and 60 children came. Because 18 children did not pay we have 129-18 = 108 attending
69 : 60 = 276: 120 = 3.02 distribution.
69 x £4 = $276 + 60-18 = 42 = 42 x 2 = $84
Combined = $276+$84 = $360
We find that an extra 8 adults didnt pay either.
Making this 69 adults and 60 children where 8 adults didn't pay and 18 children didn't pay. This way this create an average 3.02 for the 108 people attending.
3.02 x 108 = $326
80 adults and 8 child
We use ratio of 108 attendees = 328/108 = 3.03 average price which shows ratio child to adult 1:2
31 adult +42 child = $124 and $82 children = $208 children
38 more adults = 38 x 4 = 120 + 36 = $156 = (38 +18 children) = $156
= $364 - 36 = 6 child not paying = 12 and 6 adults not paying = 21
Therefore 69 adults came and 60 children came. Because 18 children did not pay we have 129-18 = 108 attending
of 48 paying and attending and the other 40 children potentially being non payers and part of
Step-by-step explanation:
4+2 = 6
8+2 = 10
4+4 = 8
We look for 80+ 28 and see 8+2 accounts for 4 adults 2 child = $20
We minus the 20 in workings and realize only when we work out 80 x 4 = 320 that only 2 child was needed and not 6 child for $12 of the 28. Because of me thinking 28 was a distribution, such resource of 4 + 1 adults became just 1 extra adult and 1 extra child.
Simply as I was chasing distribution of $24
8 of 24 was kept as
8 accounts for 1 adult and 2 child. = $8
80 accounts for 60 x $4 adults = $240 + 20 x 4 = $80
240+80=320
= $320 +$20 + $8 (-$20) = $328
Here we did not have to count back to find the correct amount only go steady with 80 distribution for 81 adults and only 2 child.

A bag contains 6 red marbles and 12 blue ones. You select one marble at random from the bag.
(1)What is the probability that you select a red marble? Write your answer in the simplest form
(2) What is the probability that you select a blue marble? Write your answer in the simplest form
1. The probability that we select a red marble is 1/3.
We found this out by taking the amount of red marbles there are and the total amount of marbles. The total amount of marbles is 18 and there are red marbles. So, it would become 6 out of 18 or 6/18. Then, we simplify 6/18 to the simplest form. The greatest common factor of both of those numbers is 6. Lastly, we divide each of them by 6 to get the simplest form.
6/18 = (6/6)/(18/6)
(6/6)/(18/6) = 1/3
So, therefore, the theoretical probability of picking a red marble is 1/3.
2. The probability that we select a blue marble is 2/3.
We can find this out by taking the amount of blue marbles there are and the total amount of marbles. We know that the total amount of marble is 18 and there are 12 blue marbles. So, we simply get the GCF (greatest common factor) and divide them by it.
Greatest Common Factor of 12 and 18 = 6
12/18 = (12/6)/(18/6)
(12/6)/(18/6) = 2/3
Thus, the theoretical probability of picking a blue marble is 2/3.

What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given a equation f(x) = 3x
Comparing with the slope-intercept form of the graph:
We can see the slope of the line will be 3 and since the y-intercept is 0
Since Function f(x) will be a linear equation
Therefore, its graph would be a line.

Suppose you want to finish running errands by 4:00 pm. Shopping will take 20 minutes. Eating will take 25 minutes. You will meet with a friend for 15 minutes. And your travel time will be a total of 20 minutes. When should you START your errands?
Answer:
2:50 pm
Step-by-step explanation:
In order to find the amount of time it takes to complete your errands, we first have to find the time it takes to complete them.
20+25+15+10=45+25=70
So, it will take 70 minutes, or 1 hour and 10 minutes to complete your errands.
We need to find what time 1 hour and 10 minutes before 4:00 is. So, one hour before 4:00 is 3:00. Then, 10 minutes before 3:00 pm is 2:50. Therefore, you have to start your errands at 2:50 pm.

A) Copy an angle
B) Copy a triangle
C) Construct an equilateral triangle
D) Construct the bisector of an angle
Answer:
Correct answer is option D) Construct the bisector of an angle.
Step-by-step explanation:
Angle bisector of an angle is a line that divides the angle in two equal parts.
A Line BD is called the angle bisector of [tex]\angle ABC[/tex] if
[tex]\angle ABD = \angle CBD[/tex]
Please refer to image attached.
As per the question image, if the line PW is joined it will be the angle bisector of [tex]\angle QPR[/tex].
Steps of construction of angle bisector:
1. Draw the angle QPR.
2. Open compass and make an arc that will cut the two lines on points Q and R respectively as shown in question figure.
3. With the same compass opening, put the compass on Q and make an arc in the area between [tex]\angle QPR[/tex].
4. Draw an arc keeping the compass on R to cut the previous arc on point W.
Line joining the points P and W is the angle bisector of [tex]\angle QPR[/tex].

Write a piecewise function that models each telephone billing plan. Then graph the function.
$60 per month buys 450 minutes. Additional time costs $0.35 per minute.
Answer: if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
Step-by-step explanation:
Here x will represent the number of minutes.
with $60 you have 450 minutes, and you must pay 60 regardless of how much minutes you use.
so if 0 < x ≤ 450, y = $60.
now, if you call for more than 450 minutes, you get an additional of $0.35 per minute, then we have:
if 450 < x ; y = $60 + (x - 450min)*$0.35
where we use (x - 450)*$0.35 because any minute after the 450 minute mark is considerated an additional time.
So our piecewise function is:
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min) × $0.35
the calculation is as follows:Here x will represent the number of minutes.
so if 0 < x ≤ 450, y = $60.
And,
if 450 < x ; y = $60 + (x - 450min) × $0.35
where we use (x - 450) ×$0.35 since any minute after the 450 minute mark is considered an extra time.

What is the equation of the circle in general form
Answer:
(x - 3)^2 + (y - 5)^2 = (√89)^2
Step-by-step explanation:
Well if you estimate, you can see that the circle touches one point at (-5, 0) and the center is at about (3, 5).
The standard equation for the circle is (x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center.
So, you can start by plugging in the center. (x - 3)^2 + (y - 5)^2 = r^2
Now, all you have to do is find the radius.
You can do this by connecting the point (-5, 0) to the center.
You will have to use the distance formula:
√(-5 - 3)^2 + (0 - 5)^2 = √64 + 25 = √89
The final equation will be (x - 3)^2 + (y - 5)^2 = (√89)^2
This is the general idea, but my answer may not be correct, so check my steps.

Use 3.14 for 77, and if necessary, round to the
nearest tenth.
10 ft
? ft
V = 314 ft3
Answer:
Height of the cylinder is 1ft
Step-by-step explanation:
Data ;
Volume = 314ft³
Assuming radius = 10ft
Height = ?
π = 3.14
Volume of a cylinder = πr²h
r = radius
h = height of the cylinder
Vol = πr²h
314 = 3.14 × 10² × h
314 = 314h
Solve for h,
h = 314 / 314
h = 1ft
The height of the cylinder is 1ft.
