A school concert has students tickets for $7 and nonstudents tickets for $12. If the school made $1973 selling 214 tickets? How many student tickets were sold? How many nonstudent tickets were sold?
Answer:
119 student tickets and 95 non-student tickets
Step-by-step explanation:
I did a trial-and-error solution.
I started with 107 students and 107 non-students:
(107*$7)+(107*$12) = $2033
It was too high, which tells us that there should be more who paid for the cheaper price.
I ended up with 119 and 95:
(119*$7)+(95*$12) = $1973
Answer:
Sample Response: Partial and negative tickets cannot be sold, so the minimum number values of e and s are 0. If s = 0, then e = 16, and if e = 0, then s = 20. Therefore, the values of s are whole numbers from 0 to 20 and the values of e are whole numbers between 0 and 16. The greatest number of student tickets sold was 20 and the greatest number of nonstudent tickets sold was 16.

1. Identify the domain and range of each function.
Answer:
The fourth listed answer:
Domain: All Real numbers
Range : { f{x) | f(x) [tex]\leq[/tex] 0, f(x) = 1 }
Step-by-step explanation:
The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.
The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value "x" of the domain. The line with positive slope extends to all f(x) values that are [tex]\leq[/tex] 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.

The half-life of silicon-32 is 710 years. If 90 grams is present now, how much will be present in 600 years? Round the answer to three decimal
places.
84.88 g
0g
0.257 g
50.102 g
Answer:
option D
Step-by-step explanation:
Given,
half life of silicon-32 = 710 years
Present silicon-32, N₀ = 90 gm
silicon-32 after 600 years,N = ?
[tex]k = \dfrac{-0.693}{t}[/tex]
[tex]k = \dfrac{-0.693}{710}[/tex]
k = -0.000976
Now,
[tex]N = N_0 e^{kt}[/tex]
[tex]N =90\times e^{-0.000976\times 600}[/tex]
[tex]N = 50.104\ g[/tex]
Hence, the correct answer is option D.
The amount of silicon-32 remaining after 600 years is 50.102 grams
Half life is the time taken for a substance to decay to half of its original amount. It is given by:
[tex]N=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\N\ is\ the\ value\ of\ the\ substance\ after\ t\ year, t_\frac{1}{2} \ is\ the\ half\ life\\and\ N_o\ is\ the \ original\ amount[/tex]
Given that half life = 710 years, original amount is 90 g, t = 600 years, hence:
[tex]N=90(\frac{1}{2} )^\frac{600}{710} \\\\N=50.102\ g[/tex]
The amount of silicon-32 remaining after 600 years is 50.102 grams

Point A is at (-7,-7) and point M is at (-6,-1). Point M is the midpoint of point A and point B. What are the coordinates of point B?
Step-by-step explanation:
M is the mid point of AB
here given A ( - 7 , -7) and M ( -6 , -1) Let the coordinates of point B be ( x1, y1)
Now
( - 6 , -1 ) = {( x1 - 7)/ 2 , ( y1 - 7) / 2}
Equating
-6 = x1 -7 -1 = y1 - 7
2. 2
-12 = x1 - 7. -2 = y1 - 7
x1 = -12 +7. y1 = -2 +7
Therefore x1 = - 5. Therefore y1 = 5
Therefore the coordinates of B is ( -5 , 5)
Answer:
the coordinates of B is ( -5 , 5)

What is the sample space for choosing an odd number from 1 to 11 at random
Answer:
{1, 3, 5, 7, 9, 11}
The sample space of the odd number will be (1, 3, 5, 7, 9, 11).
Sample space simply means the possible outcomes that we can get when we make an experiment.
Odd numbers cannot be divided by 2. Examples include 1, 9, 11, 23, 45, 75 etc. In this case, the odd numbers that we can get from 1 to 11 will be 1, 3, 5, 7, 9 and 11 and this will be the sample space.
In conclusion, the sample space will be (1, 3, 5, 7, 9, 11)

Write the quadratic equation in standard form.
(x-3) 2=0
0x²+9=0
0x2+6x+9=0
0x2 - 6x +9=0
To determine the correct standard form of a quadratic equation from the given options, we expand (x-3)2 to get [tex]x^2 - 6x + 9 = 0,[/tex] which is the correct standard form [tex]ax^2 + bx + c = 0.[/tex]
To write the quadratic equation in standard form, you need to remember that the standard form is ax2 + bx + c = 0. The given equations will be compared to this standard form to find the correct answer.
Given Equations:
(x-3)2=0
0x2+9=0
0x2+6x+9=0
0x2 - 6x +9=0
Only the first equation, (x-3)2=0, can be simplified to the standard quadratic form if expanded. Let's expand it:
(x-3)2 = x2 - 6x + 9
So the correct standard form of the given equation is x2 - 6x + 9 = 0.
The other options, due to having a coefficient of 0 for x2, are not proper quadratic equations as they do not have the quadratic term.

Answer:
hope i helped
Step-by-step explanation:
Point D (3,1); Point B (-1,-2); Point C (4, -2)
Point D lies on the circle whose center is Point B and which contains the Point C if the distance:
BD = BC
BD^2 = BC^2
(- 1 - 3)^2 + (- 2 - 1)^2 = (4 - (-1))^2 + (-2 - (-2))^2
16 + 9 = 25
25 = 25
Follows, point D lies on the circle with radii 5.
To solve graphically we first need to write the equation of the circle whose center is Point B and which contains the Point C:
(x - (-1))^2 + (y - (-2))^2 = 5^2
(x + 1)^2 + (y + 2)^2 = 5^2
It took Rachel 9.3 minutes to run a mile. It took Chris 0.9 times as long as it took Rachel to run the same distance. How long did it take Chris to run a mile?
Answer:
8.37 minutes
Step-by-step explanation:
The key word times helps us know what operation we're doing, which is multiplication. Multiply 9.3 by 0.9 to get your answer.
What is the area of the trapezoid? [A = 1/2(b1 + b2)h]
A) 1249.5 sq cm
B) 162.75 sq cm
C) 105 sq cm
D) 38.75 sq cm
We can see that b1 = 18, b2 = 24, and h = 5
So, we can just substitute these in.
A = 1/2(18 + 24)5
A = 1/2 * 42 * 5
A = 21 * 5
A = 105
So, the answer is C. 105 sq cm

Bob is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.
Company A charges $76 and allows unlimited mileage.
Company B has an initial fee of $55 and charges an additional $0.70 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
m = the number of miles driven
Company A cost = 76
[they charge $76 for unlimited mileage, so they don't charge by the miles driven]
Company B cost = 0.70m + 55
[they charge an initial fee of $55 plus $0.70 per mile(m)]
For what mileages will Company A charge less than Company B?
Company A cost < Company B cost -----> 76 < 0.70m + 55
To solve for m, isolate/get the variable "m" by itself in the inequality:
76 < 0.70m + 55 Subtract 55 on both sides
76 - 55 < 0.70m + 55 - 55
21 < 0.70m Divide 0.70 on both sides to get "m" by itself
[tex]\frac{21}{0.70} <\frac{0.70m}{0.70}[/tex]
30 < m [m is any number greater than 30]
Company A will charge less than Company B for mileages over/greater than 30.
Final answer:
Company A will charge less than Company B when more than 30 miles are driven; the inequality used to determine this is 76 < 55 + 0.70m, and after solving, it shows that m > 30.
Explanation:
To find out for what mileages Company A will charge less than Company B, we need to set up an inequality based on the given price structures for both companies:
Company A charges a flat rate of $76 per day, regardless of mileage.
Company B charges an initial fee of $55 plus $0.70 per mile driven.
The inequality to represent this scenario is:
76 < 55 + 0.70m
To solve for m (the number of miles driven), we subtract 55 from both sides:
21 < 0.70m
Then, divide both sides by 0.70 to isolate m:
m > 30
So, Company A will charge less than Company B when Bob drives more than 30 miles.
using substitution and elimination method solve this simultaneous equation
Y=x+1
X+Y=3
Answer:
x = 1 and
Y = 2
Step-by-step explanation:
1. Y = x + 1
2. X + Y = 3
Substitute equation 1 into equation 2
X + Y = 3
X + X + 1 = 3
2x + 1 = 3
Subtract 1 from both sides to eliminate 1 on the left side
2x + 1 - 1 = 3 - 1
2x = 2
Divide both sides by 2 to isolate x
2x/2 = 2/2
x = 1
Substitute 1 for x in either equation to get Y
Using equation one, we have
Y = x + 1
= 1 + 1
= 2
x = 1
Y = 2
Check
X + Y = 3
1 + 2 = 3
3 = 3
