total of 640 tickets were sold for the school play. They were either adult tickets or student tickets. There were 60 fewer student tickets sold than adult tickets.
w many adult tickets were sold?
380 adult tickets.
640 divided into the sub categories of student and adults would be 320. at this point you don't even have to do any of the math for students because you already know there would be 60 less student tickets so you can just add the 60 to 320 for adults. So 380

What is the general form of the equation of the line shown?
Answer:
the general form of the equation of the line will be:
[tex]y-x=2[/tex]
Step-by-step explanation:
Finding the slope:
Taking two points from the line as shown in figure
(-2, 0)(0, 2)Finding the slope between (-2, 0) and (0, 2)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:0\right),\:\left(x_2,\:y_2\right)=\left(0,\:2\right)[/tex]
[tex]m=\frac{2-0}{0-\left(-2\right)}[/tex]
[tex]m=1[/tex]
Finding the y-intercept
We know that the y-intercept can be calculated by setting x=0
From the figure, it is clear that at x=0, y=2
Thus, the y-intercept is (0, 2)
We know that the slope-intercept form of the equation line is:
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
As we have already determined the slope = m = 1 and the y-intercept b=2.
Substituting the values in the slope-intercept form of the equation line
[tex]y=mx+b[/tex]
[tex]y=(1)x+2[/tex]
[tex]y=x+2[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
As we already know the equation in slope-intercept form
[tex]y=x+2[/tex]
so just simplify the equation to write in standard form
[tex]y-x=2[/tex]
Thus, the general form of the equation of the line will be:
[tex]y-x=2[/tex]
The Historic Triangle in Virginia connects Jamestown, Williamsburg, and Yorktown. The interior angle at Williamsburg is 120°. The interior angle at Jamestown is twice the measure of the interior angle at Yorktown. Find the measures of the interior angles at Jamestown and Yorktown.
Answer: Interior angles at Jamestown and Yorktown are 40° and 20°, respectively
Step-by-step explanation: Jamestown, Williamsburg and Yorktown form a triangle. The sum of the interior angles of a triangle is 180°.
Suppose interior angle at Yorktown is x. As Jamestown is twice the measure at Yorktown, it means this interior angle is 2x.
Then, the measures will be:
2x + x + 120 = 180
3x = 60
x = 20
Angle at Yorktown is 20°.
So, angle at Jamestown is
2x = 2.20 = 40°
The measures of the interior angles at Jamestown and Yorktown are 40° and 20°, respectively.

So,
The following statements are incorrect:
A flowchart proof gives a visual representation of the sequence of steps without justifications.
A two-column proof lists only the given information and what is to be proven.
Thus,
The correct statements are:

In how many years will $12,000 yield an interest of $4,800 at 10% simple interest? *
A. 25 years
B. 0.04 year
C. 4 years
D. 0.25 years or 3 months
Answer:
Time= 4 years
Step-by-step explanation:
Giving the following information:
Principal (P)= $12,000
Interest rate (r)= 10% = 0.10
Interest earned (I)= $4,800
To calculate the time required to gain $4,800 interest, we need to use the following formula:
T= I / (P*r)
T= 4,800/(12,000*0.1)
T= 4 years
In rectangle PLAN, PT = x + 3 and TL = 3x - 11. What are the lengths of PA and NL?
Answer:
PA = 20 units
NL = 20 units
Step-by-step explanation:
Property of a rectangle,
"Diagonals of a rectangle are equal in measure and divide each other in two equal parts"
By using this property,
PT = TL
(x + 3) = (3x - 11)
3x - x = 11 + 3
2x = 14
x = 7
Length of PT = (x + 3) = 10
Length pf PA = 2(PT) = 20 units
Length of NL = PA = 20 units
. Austin wants to buy some pens and pencils. He has $30 in his bag. Each pen costs $5 and each pencil costs $1.50. He needs 5 more pencils than pens.Part A how many pencils can $ustin buy at most" Write your answer and your work or explanation in the space below. Part If Austin had $40 in his bag, how many pens could Austin buy at most" Explain how you found the answer in the space below.
Answer:
3 pens
Step-by-step explanation:
Total expenditure (Price x Quantity) on pens & pencils = $30
Let pen quantity be = x , Let pencil quantity be = y
Given : Pen (x) price = 5 , Pencil (y) price = 1.5 , Pencils (y) = Pen (x) + 5
So, 5x + 1.5y = 30
5x + 1.5 (x + 5) = 30 → 5x + 1.5x + 7.5 = 30 → 6.5x + 7.5 = 30
6.5x = 30 - 7.5 → 6.5x = 22.5
x = 22.5 / 6.5 → x = 3.46 ≈ 3 pens

» Which pair of numbers has an LCM of 60?
2 and 12
5 and 12
6 and 12
3 and 12
Answer: 5 and 12
Step-by-step explanation:
2 and 12 is not it because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.
6 and 12 is not it because 12 can also be divided by 6 meaning that the LCM of 6 and 12 is also 12.
3 and 12 is also the same, 12 can be divided by 3 so their LCM will be 12.
With 5 and 12, 12 is not divisible by 5 so you will have to find the multiples of 5 and 12 and it will eventually be 60.
Multiples of 5: 5, 10,15,20,25,30,35,40,45,50,55,60,65
Multiples of 12: 12, 24, 36, 48, 60, 72
As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.
Answer:
It's 5 and 12

Calculate the volume of both containers.
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
[tex]V_{A}[/tex] = π × 10² × 11 = 1100π ft³
[tex]V_{B}[/tex] = π × 7² × 19 = 931π ft³
Subtract volume of B from volume of A to find quantity left in A
quantity left in A = 1100π - 931π = 169π ft³
To calculate the percentage left in A after B has been filled
[tex]\frac{left}{full}[/tex] × 100%
= [tex]\frac{169\pi }{1100\pi }[/tex] × 100%
= [tex]\frac{169}{1100}[/tex] × 100%
= 15.4% ( to the nearest tenth )
