An hour before show time, only 108 people are seated for a musical performance. According to the ticket sales, 97% of the people have yet to arrive. How
many tickets were sold for the musical performance?
Answer:
3600 tickets were sold for the musical performance.
Step-by-step explanation:
Given that:
Number of people seated for musical performance = 108
Percent to people to arrive yet = 97%
It means that the people who have already come are 3%.
Let,
x be the number of tickets sold.
3% of x = 108
[tex]\frac{3}{100}x=108\\[/tex]
0.03x = 108
Dividing both sides by 0.03
[tex]\frac{0.03x}{0.03}=\frac{108}{0.03}\\x=3600[/tex]
Hence,
3600 tickets were sold for the musical performance.
At aa car dealership, for every 4 silver cars that are sold, 6 red cards are also sold. If 90 cars. Total are sold in a month, how many silver cars were sold?
Answer: 36
Step-by-step explanation:
From the question, we are informed that for every 4 silver cars that are sold, 6 red cards are also sold.
When there are 90 cars sold in a month, the number of silver cars that were sold would be:
= [4 / (4 + 6)] × 90
= 4/10 × 90
= 4 × 9
= 36 silver cars

What is the surface area of the cylinder with height 5 yd and radius 7 yd?
Answer:
168*pi square yards.
Step-by-step explanation:
So, first the surface area of a cylinder is the sum of the two circles plus the rectangle forming the column.
The area of the column is the height x perimeter of the circle
and
The area of the circles is pi x radius^2
Just add all of those up.
Column: 5 * 2 * pi * 7 = height * 2pi * radius = 70*pi
2 x Circle = 2 x pi * 7^2 = 2x49*pi = 98*pi
Sum: 70*pi + 98*pi = 168* pi
Antonio tried to evaluate an expression. Here is his work: (57–8+5)÷9(17–14) = (49+5)÷93 Step 1 = (49+5)÷27 Step 2 = 54÷27 Step 3 = 2 Step 4 Is Antonio's work correct?
Answer:
Antonio's work is correct but his method is not
Step-by-step explanation:
(57–8+5)÷9(17–14) = (49+5)÷9
Antonio work:
Step 1 = (49+5)÷27
Step 2 = 54÷27
Step 3 = 2
Correct working:
Step 1:
Addition first
-8 + 5 = -3
= (57 - 3) ÷ 9(3)
Step 2:
= 54 ÷ 27
Step 3:
= 2
Antonio's work is correct but his method is not

complete the function table for the given domain and plot the points on the graph f(x)=(x-5)^2+1
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
f(x) = (x-5)²+1
put x = 2
f(2) = (2-5)²+1 = (-3)²+1 = 9+1 = 10
put x = 3
f(3) = (3-5)²+1 = (-2)²+1 = 4+1 = 5
put x = 4
f(4) = (4-5)²+1 = (-1)²+1 = 1+1 = 2
put x = 5
f(5) = (5-5)²+1 = (0)²+1 = 0 + 1 = 1
put x = 6
f(5) = (6-5)²+1 = (1)²+1 = 1 + 1 = 2
Thus, the table wil be completed as:
x 2 3 4 5 6
f(x) 10 5 2 1 2
Please check the attached figure for the plotting graph.

The length of a school bus is 12.6 meters. If 9 school buses park end to end with 2 meters between each one, what's the total length from the front of the first bus to the end of the last bus?
Answer:
129.4
Step-by-step explanation:
Calculation for what's the total length from the front of the first bus to the end of the last
First step is to multiply the given number of buses by the length of each one
Hence,
12.6 meters x 9 = 113.4 meters
Second step
Since there are 8 spaces in between we would multiply the 8 spaces by 2 meters
8 x 2 meters = 16
Now let calculate total length from the front of the first bus to the end of the last
16 + 113.4 meters =129.4
Therefore total length from the front of the first bus to the end of the last will be 129.4

Find the center and the radius and the center of the circle with the given equations:
Answer:
3. (-1 , 3) , 4
4. (0 , -7), 8
Step-by-step explanation:
circle: (x-h)² + (y-k)² = r²
3. x²+2x+y²-6y-6 =0
(x²+2x+1) + (y²-6y+9) -16 =0
(x+1)² + (y-3)² = 4²
center(-1 , 3) radius: 4
4. x²+y²+14y-15=0
(x+0)² + (y²+14y+7²) - 64 = 0
(x+0)² + (y+7)² = 8²
center: (0 , -7) radius: 8
Answer:
3. Center = (-1,3) Radius = 4
4. Center = (0,-7) Radius = 8

In your own words, what is the least common multiple of two whole numbers? How can you find it?
Answer:
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Find the measure of each missing angle.
Answer:
m< 3 = 180 - 93
m< 3 = 87 degrees
m< 4 = 180 - 87 - 49
m< 4 = 44 degrees
m< 2 is vertically opposite to the 49 degree angle given
m< 2 = 49 degrees
m< 1 = 180- 68 - 49
m< 1 = 63 degrees
The measure of each missing angle are; m< 1 = 63, m< 2 = 49, m< 3 = 87 and m< 4 = 44 degrees
What are vertically opposite angles?The vertically opposite angles are those angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.
We can determine angle 3 as;
m< 3 = 180 - 93
m< 3 = 87 degrees
Also,
m< 4 = 180 - 87 - 49
m< 4 = 44 degrees
We can see that m< 2 is equal to 49-degree angle by a vertically opposite angle.
m< 2 = 49 degrees
m< 1 = 180- 68 - 49
m< 1 = 63 degrees
Hence, the measure of each missing angle are; m< 1 = 63, m< 2 = 49, m< 3 = 87 and m< 4 = 44 degrees

Help? Will give brainliest
Answer:
2) A
3) A
Step-by-step explanation:
2:
3y + 4x = 15
(divide 15 by 3 to get y by itself... then subtract 4 to the side with 15 so you have the proper equation)
y = 5 - 4x (when you graph it, the y intercept is 5)
3:
since x = -4y ... you substitute that into the second equation
-4y + 5y = 2
then solve for y
y = 2
so now you substitute y into the first line
x = -4(2)
x = -8
