Mr. Ramirez purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under the age of 12. What does the solution to the system of equations represent in the context of the problem? Explain.
Answer: $225 = $15 a + $ 10 c
Step-by-step explanation:
price = $225
concert ticket for adults= $15
concert ticket for children = $10
System of equation to represent scenario
a is variable for adult
c is variable for children
Total price = $15 a + $ 10 c
$225 = $15 a + $ 10 c

Piano lessons with Ms. Cohen cost $30 for 3/4 of an hour. What is Ms. Cohen's hourly rate?
Answer:
$40.
Step-by-step explanation:
To find the hourly rate, we can divide the price and the time.
We know that Ms.Cohen charges $30 for 3/4 of an hour. So, we will perform:
[tex]30\div\frac{3}{4}[/tex]
We dividing fractions, we keep, change, and flip. Hence:
[tex]=30\times\frac{4}{3}[/tex]
Multiply:
[tex]=\frac{120}{3}=\$40[/tex]
Therefore, the hourly rate is $40.
And this is the hourly rate because it is $40/1 hour. We can ignore the 1, so it’s just $40 per hour.
Answer:
$40
Step-by-step explanation:
If is $30 for 3/4 then you add 1 more to get 4/4 you get $10 added to $40

A baseball is thrown in a parabolic arc. It's position above the ground at a given
point in time can be represented by the quadratic function
p(t) = {gt2 + vot + Po, where t > 0. g is -32 ft/sec/sec, vo is initial
velocity, and Po is its initial position above the ground. If the ball was thrown
straight up at 40 ft/sec when it was 5 ft above the ground, how high did it go?
(Type the number, do not include units in your answer)
Answer:
P(t) = 17.5 feet
Step-by-step explanation:
The position above the ground at a given point in time can be represented by the quadratic function as follows:
[tex]P(t)=gt^2 + vot + Po[/tex]
Where,
Po is the initial position above the ground
If the ball was thrown straight up at 40 ft/sec when it was 5 ft above the ground.
We need to find the height reached by the ball.
The equation will become :
[tex]P(t)=-32t^2 + 40t+ 5[/tex]
Firstly we find the time taken to reach its maximum height
Put, dP(t)/dt = 0
[tex]\dfrac{d(-32t^2+40t+5)}{dt}=0\\\\-64t+40=0\\\\t=0.625\ s[/tex]
Now put t = 0.625 in equation (1) as follows :
[tex]P(0.625)=-32(0.625)^2 + 40(0.625)+ 5\\\\=17.5\ \text{feet}[/tex]
So, it will go at a height of 17.5 feet.

Which of the following is the slope of the line passing through the points A(-6, 10) and B(-2, 7)
Answer:
[tex]m=\frac{-3}{4}[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define Points
A (-6, 10)
B (-2, 7)
Step 2: Find slope m
Substitute: [tex]m=\frac{7-10}{-2+6}[/tex]Subtract/Add: [tex]m=\frac{-3}{4}[/tex]And we have our final answer!
Answer:
[tex]-\frac{3}{4}[/tex]
Step-by-step explanation:
To find the slope of the line, we use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when we are given the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].
When we plug the points A(-6,10) and B(-2,7) into the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], we get the equation [tex]\frac{7-10}{-2-(-6)}[/tex].
[tex]\frac{7-10}{-2-(-6)}\\= \frac{-3}{4}[/tex]
Therefore, the slope of the line is [tex]-\frac{3}{4}[/tex].

Peter hired a cleaning company to clean his house. The cleaning company charges a fixed fee of $15
plus $17 per hour to clean a house.
a. Write an equation that can be used to determine, c, the total amount in dollars that the cleaning
company charges to clean a house in h hours.
17t + 15 is the charge for "t" hrs of work.
b. The cleaning company charged a total of $83 to clean Peter's house. How many hours did it take to
clean Peter's house?
Answer:
y= total charge for cleaning
x= number of hours of cleaning
Equation y=15+17x
For example, if the company cleaned for 2 hours it would be y=17+15(2)
y=17+30
y= 30 dollars
Hope this helps!

Does △ABC appear to be the same size and shape as △XYZ? Explain.
Right triangles A B C and X Y Z. A B C has shorter leg equal to 5 and hypotenuse equal to 13. Longer leg B C is horizontal. X Y Z has shorter leg equal to 5 and hypotenuse equal to 13. Hypotenuse X Y is horizontal.
A. Yes; △ABC maps onto △XYZ with a translation and a rotation.
B. Yes; △ABC maps onto △XYZ with a translation and a reflection.
C. Yes; △ABC maps onto △XYZ with a rotation and a reflection.
D. No; the triangles are different sizes.
Answer:
yes
Step-by-step explanation:
Yes, △ ABC appears to be the same size and shape as △ XYZ by SAS similarity, and △ ABC can be mapped by translation and rotation, so option A is correct.
What is triangle?Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes, it is represented by the symbol and consists of three connected vertices.
Given:
Right triangles ABC and XYZ. ABC has a shorter leg equal to 5 and a hypotenuse equal to 13,
The triangles ABC and XYZ are similar by SAS similarity, as,
AC = XZ = 5,
AB = YZ = 13
∠ ACB = ∠ XZY
When you translate and then rotate triangle ABC, you will get triangle XYZ.

Q16. Find the area of the shaded region (4 corners) with each side = 12 in.
1 3.14
12 in
Use
12 in
Answer:
D. 30.96 in²
Step-by-step explanation:
The area of the shaded region = area of the the square - area of the circle
= (s²) - (πr²)
s = 12 in
r = radius of circle = ½ of 12 in = 6 in
π = 3.14
Plug in the values into the equation
Area of the shaded region = (12²) - (3.14*6²)
= 144 - 113.04
= 30.96 in²

A survey was conducted in a class with 20 students about their favorite sport. Five students chose basketball, 8 students chose football, and 7 chose soccer. Based on this information, predict how many would NOT choose soccer if there were 460 students in the survey. 150 30b 230 • 160
Answer: 299
Step-by-step explanation:
Out of 20 students, 5 students chose basketball, 8 students chose football, and 7 chose soccer.
Students chose basketball and football=5+8=13
Fraction of students not chose soccer = [tex]\dfrac{13}{20}[/tex]
Assume that the fraction remains the same.
If there were 460 students, then the number of students not chose soccer [tex]=460\times\dfrac{13}{20}\\\\=299[/tex]
Hence, the number of students not chose soccer =299
What's e=mc²? I need it for my math class
Answer:
E = mc^2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
Step-by-step explanation:
E = energy
m = mass
c = the speed of light
Answer:
E represents units of energy, m represents units of mass, and c2 is the speed of light squared,
Step-by-step explanation:
So energy = mass times speed squared
