The MTC Theater holds 250 people, and last night’s performance sold out! Students paid $3.00 per ticket, while adults paid $5.00 per ticket. Last night’s show brought in $1050.
Write a system of equations for the problem.
9514 1404 393
Answer:
s + a = 2503s + 5a = 1050Step-by-step explanation:
Let s and a represent the numbers of student and adult tickets sold. The system of equations that can be written from the given information is ...
s + a = 250 . . . . . . total of tickets sold
3s +5a = 1050 . . . dollar value of tickets sold
_____
The solution is (s, a) = (100, 150). 100 student tickets and 150 adult tickets were sold.

Let f(x)=x2+3x+2.
What is the average rate of change of f(x) from 3 to 6?
−112
12
−12
112
Answer:
12
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 3, 6 ] , then
f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56
f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then
average rate of change = [tex]\frac{56-20}{6-3}[/tex] = [tex]\frac{36}{3}[/tex] = 12
Answer:
12
Step-by-step explanation:
Given a polynomial f(x), if (x − 4) is a factor, what else must be true? f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0
Question:
Given a polynomial f(x), if (x − 4) is a factor, what else must be true?
f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0_______________________________________
Solution:
f(x) is a polynomial.
(x - 4) is a polynomial of f(x).
By converse of factor theorem: If (x - a) is a factor of f(x), then, f(a) = 0.
On comparing (x - 4) with (x - a), we get,
a = 4So,
f(a) = 0
=> f(4) = 0
thabo rounded the number of marbles to the nearest 5. His answer was 340. write down 2 possible numbers for the actual number of marbles.
Answer:
338 or 335 they both get rounded of to the nearest 5
2 possible numbers for the actual number of marbles 338 and 335, are rounded to the nearest 5.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, Thabo rounded the number of marbles to the nearest 5 and his answer was 340.
Therefore, 2 possible numbers for the actual number of marbles could be
Whether it's 338 or 335, both numbers are rounded to the nearest 5.

Calculate the area of the shape below
3 1/2
Answer:
option B by using formula of area of circle.The new patio at Tonya's house is 5 yards long by 10 feet wide. She is going to cover the patio with square bricks that measure 1 foot on each side. If each brick costs $4, how much will Tonya pay for the bricks? A rectangle that is five yards long and ten feet wide A. $600 B. $120 C. $150 D. $200
Answer:
A
Step-by-step explanation:
Steps to take to determine the answer
Because the length is in yards, it has to be converted to footFind the area of the patio using the length and width measured in footDetermine the area of the square brickMultiply the cost of the brick by the area1 yards = 3 foot
5 x 3 = 15 foot
Area of a rectangle = length x breadth
15 x 10 = 150 ft^2
Cost = 150 x 4 = $600

In △BCD
∠BDC= 180° -90° (adj. ∠s on a str. line)
∠BDC= 90°
Applying Pythagoras' Theorem,
(BD)² +(DC)²= (BC)²
(BC)²= 6² +4²
(BC)²= 52 -----(1)
In △ABD
Applying Pythagoras' Theorem,
(AD)² +(BD)²= (AB)²
(AB)²= x² +6²
(AB)²= x² +36 -----(2)
In △ABC
Applying Pythagoras' Theorem,
(AB)² +(BC)²= (AC)²
(AB)² +(BC)²= (x +4)²
Substitute (1) and (2):
x² +36 +52= (x +4)²
x² +88= x² +2(x)(4) +4² (simplify, expand)
x² +88= x² +8x +16
8x +16= 88 (-x² on both sides)
8x= 88 -16
8x= 72
x= 72 ÷8
x= 9

2x = 24
x = 12
∠ABC = 4(12) + 6 = 54°
Traverion wants to find the answer to the question “How much money does the average college professor make?” He surveys 50 professors from the university in his hometown. Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
The results do not represent the population because not all college professors actually responded.
The results do not represent the population because the sample does not represent professors from different areas.
The results represent the population because the sample contained college professors and the population is college professors.
The results represent the population because he sampled a large number of professors.

Step-by-step explanation:
write the equation fully simplified slope intercept form
Answer:
y = -1/5x - 1
Step-by-step explanation:
The line crosses the y axis at -1, making it the y-intercept.
Since the line is going downwards from left to right, we know that it is a negative slope.
The line goes down one and 5 right. That makes the slope -1/5.
The equation is y = -1/5x - 1
