Some History teachers at Dayton High School are purchasing tickets for students and their adult chaperones to go on a field trip to a nearby museum. For her class, Mrs. Gruber bought 25 student tickets and 28 adult tickets, which cost a total of $984. Mr. Ellison spent $900, getting 25 student tickets and 25 adult tickets. What is the price for each type of ticket?
Answer:
Student Ticket: $8
Adult $28
Step-by-step explanation:
To find out the price of each ticket create 2 equations, then solve for x & y
x = student tickets
y = adult tickets
25x + 28y = 984
25x + 25y = 900
To do this first put x on one side of the equation
25x = 900 - 25y
x = 36 - y
Now substitute this equation in x for the first equation
25(36 - y) + 28y = 984
Now distribute 25 in 36 - y, 900 - 25y + 28y = 984
After this combine like term, then subtract 900 from each side, 3y = 84
Then divide 3 on each side, y = 28
Lastly substitute 28 for y in any equation to solve for x, x = 8
x & y are the price of each ticket

please someone help me to prove this.
Answer: see proof below
Step-by-step explanation:
Use the Double Angle Identity: sin 2Ф = 2sinФ · cosФ
Use the Sum/Difference Identities:
sin(α + β) = sinα · cosβ + cosα · sinβ
cos(α - β) = cosα · cosβ + sinα · sinβ
Use the Unit circle to evaluate: sin45 = cos45 = √2/2
Use the Double Angle Identities: sin2Ф = 2sinФ · cosФ
Use the Pythagorean Identity: cos²Ф + sin²Ф = 1
Proof LHS → RHS
LHS: 2sin(45 + 2A) · cos(45 - 2A)
Sum/Difference: 2 (sin45·cos2A + cos45·sin2A) (cos45·cos2A + sin45·sin2A)
Unit Circle: 2[(√2/2)cos2A + (√2/2)sin2A][(√2/2)cos2A +(√2/2)·sin2A)]
Expand: 2[(1/2)cos²2A + cos2A·sin2A + (1/2)sin²2A]
Distribute: cos²2A + 2cos2A·sin2A + sin²2A
Pythagorean Identity: 1 + 2cos2A·sin2A
Double Angle: 1 + sin4A
LHS = RHS: 1 + sin4A = 1 + sin4A [tex]\checkmark[/tex]

George's total points is 5 less than susan's total points. Does geroge need more points or fewer susan points?
Answer: Need more points.
Step-by-step explanation:
If George's total point is 5 less than susan's points then George needs more points to make up to susan or pass susan's points.
For example ,
g = s - 5 where g is George's points and s is susan's point.
As you can see for G to catch up with s you will need 5 more points.

distance it moved between two positions. Use the "distance on the number line "formula.
Answer:
29.4 meters
Step-by-step explanation:
Given the following :
A submarine ascended from 56.8 meters under the sea level to 27.4 meters under the sea level.
distance it moved between two positions. Use the "distance on the number line "formula
Initial Position or distance of submarine before ascension = 56.8 meters
Final position after ascension = 27.4 meters
The distance moved by the submarine between the two positions can be obtained by.
(Initial distance - Final distance)
(56.8 - 27.4) = 29.4 meters
If two of these shapes are randomly chosen, one after the other without replacement, what is the probability that both chosen will be triangles?
Answer:
[tex]P(T_1\ n\ T_2) = \frac{2}{21}[/tex]
Step-by-step explanation:
From the comments in your question; we have
Stars = 4
Triangles = 5
Circles = 3
Squares = 3
Required
Determine the probability of both shapes being triangles
First, calculate the total
[tex]Total = 4 + 5 + 3 + 3[/tex]
[tex]Total = 15[/tex]
Next, calculate the probability of the first selected shape being a triangle;
P(T₁) = Number of triangles divided by total number of shapes
[tex]P(T_1) = \frac{5}{15}[/tex]
[tex]P(T_1) = \frac{1}{3}[/tex]
Next, calculate the probability of the second selected shape being a triangle;
P(T₂) = Number of triangles divided by total number of shapes
Because it's probability without replacement. the number of triangle left is 4 and the number of shapes left is 14;
So:
[tex]P(T_2) = \frac{4}{14}[/tex]
[tex]P(T_2) = \frac{2}{7}[/tex]
Hence:
[tex]P(T_1\ n\ T_2) = P(T_1) * P(T_2)[/tex]
[tex]P(T_1\ n\ T_2) = \frac{1}{3} * \frac{2}{7}[/tex]
[tex]P(T_1\ n\ T_2) = \frac{2}{21}[/tex]
Hence, the required probability is [tex]\frac{2}{21}[/tex]
Answer:
2/21
Step-by-step explanation:
There are 4 stars, 5 triangles, 3 circles, and 3 squares
For the first drawing there are 5 triangles and a total of 15 shapes.
p(first triangle) = 5/15 = 1/3
Since there is no replacement, for the second drawing, and one triangle has been taken, now there are 4 triangles left and 14 total shapes left.
p(second triangle) = 4/14 = 2/7
p(two triangles) = p(first triangle) * p(second triangle)
p(two triangles) = 1/3 * 2/7
p(two triangles) = 2/21

Problem Fernanda wants to tile her 5 m × 2.5 m 5 m×2.5 m5, start text, space, m, end text, times, 2, point, 5, start text, space, m, end text room. She has two options, granite, and marble. Granite costs 600 600600 rupees per square metre and marble costs 1000 10001000 rupees per square metre. What is the additional cost of using marble to tile the floor instead of granite? rupees
Answer:
5000 rupees
Step-by-step explanation:
Given the following :
Dimension of room = 5m × 2.5m
Cost of granite = 600 rupees per square meter
Cost of marble = 1000 rupees per square meter
Additional cost of using marble instead of granite :
Area of room = Area of rectangle = Length * width
Area of room = 5m × 2.5m = 12.5m^2
Cost of using granite:
Area of room × cost of granite per square meter
12.5 × 600 = 7500 rupees
Cost of using marble:
Area of room × cost of marble per square meter
12.5 × 1000 = 12,500 rupees
Difference in cost :
(12500 - 7500) rupees = 5000 rupees
Additional cost incurred if marble is used = 5000 rupees
A rectangular flour canister has dimensions of 512 inches by 4 inches by 10 inches. A smaller sugar canister has dimensions of 312 inches by 3 inches by 8 inches. How much smaller is the volume of the sugar canister than the flour canister? 84 cubic inches 136 cubic inches 220 cubic inches 304 cubic inches
Answer:
The correct option;
136 cubic inches
Step-by-step explanation:
The dimension of the rectangular flour canister are;
Length = 5 1/2 inches (5.5 inches)
Width = 4 inches
Height = 10 inches
The dimensions of the smaller sugar canister
Length = 3 1/2 inches (3.5 inches)
Width = 3 inches
Height = 8 inches
The volume of a cube is given by the relation;
V = Length × Width × Height
Therefore, we have;
The volume of the rectangular flour canister = 5 1/2 × 4 × 10 = 220 in³
The volume of the rectangular sugar canister = 3 1/2 × 3 × 8 = 84 in³
The difference in volume between the two canisters = 220 in³ - 84 in³ = 136 in³
The difference in volume between the two canisters = 136 in³

Answer: [tex]x = \frac{\pi}{4} \ \text{radians}, \ \ y = \frac{\sqrt{2}}{2}[/tex]
Note: pi/4 radians is equal to 45 degrees
===========================================
To get this answer, you can use the unit circle to see that at 45 degrees or pi/4 radians, the sine and cosine value are both [tex]\frac{\sqrt{2}}{2}[/tex]
You could also use your calculator to graph y = sin(x)-cos(x) to find the x intercept in the interval [tex]0 < x < \frac{\pi}{2}[/tex] to find the approximate x intercept to be x = 0.70710678
Then note how [tex]\frac{\sqrt{2}}{2} \approx 0.70710678[/tex]
-----------------------------
Or you could do the following steps
sin(x) = cos(x)
sin^2(x) = cos^2(x)
sin^2(x) = 1 - sin^2(x)
sin^2(x) + sin^2(x) = 1
2sin^2(x) = 1
sin^2(x) = 1/2
sin(x) = sqrt(1/2)
sin(x) = sqrt(2)/2
Again you'll have to turn to the unit circle, or some reference sheet, to determine the x value that makes the last equation above to be true. That x value is x = pi/4 radians.

The height Abby climb above their original starting position is 20 feet.
How do we make graph of a function?Suppose the considered function whose graph is to be made is
f=f(x) f(x)
The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values
f=f(x) f(x)
are plotted on the vertical axis.
They are together plotted on the point
f(x)) (x,y) = (x, f(x))
This is why we usually write the functions as:
f(x) y = f(x)
We are given that;
Time= 12min
Now,
To find how high Abby climbed above their original starting position, we need to look at the graph and find the highest point of Abby’s climb.
We can see that Abby’s climb is represented by the blue line on the graph.
The highest point of Abby’s climb is at (6, 22), which means that after 6 minutes, Abby reached a height of 22 feet.
Since the original starting position is at (0, 2), which means that at the beginning, Abby was at a height of 2 feet, we can subtract 2 from 22 to find how high Abby climbed above their original starting position.
Abby climbed 22 - 2 = 20 feet above their original starting position.
Therefore, by the graph the answer will be 20 feet.

An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is exactly 4 times smaller than the actual bridge. 16 ounces = 1 pound. 2,000 pounds = 1 ton. If a test of the model shows that it holds 8,000 ounces, will the bridge hold 1 ton?
Answer:
Yes, the bridge will hold 1 ton.
Step-by-step explanation:
The ratio of the scale of the model to the real bridge = 1:4
The test model shows the model can take 8000 ounces
The real bridge will therefore take 8000 x 4 = 32000 ounces
but,
16 ounces = 1 pound
32000 ounces = [tex]x[/tex] pounds
==> [tex]x[/tex] = 32000/16 = 2000 pounds
also,
2000 pounds = 1 ton,
therefore, the bridge will hold 1 ton
Answer:
it would be able to hold 1 ton

Answer:
[tex]y=-\frac{2}{3}x+12[/tex]
Step-by-step explanation:
Step 1: Rule out answers
The answer cannot be B or D because the y-intercept is at 12(b = 12) and in a linear equation y=mx+b, b is the y intercept.
B has the y intercept at 18
D has the y intercept at 18
Step 2: Find the slope
The slop is the change in y over the change in x. We can also write this as [tex]\frac{rise}{run}[/tex]
We see it lowers by 2 so we will put -2 as the numerator
We also the x value increase by 3 every time it gets lowered by 2 so the run is 3
Therefore the slope is [tex]-\frac{2}{3}[/tex]
Step 3: Plug in the the variables to get the linear equation
[tex]y=mx+b[/tex]
[tex]y=-\frac{2}{3}x+12[/tex]
Therefore the answer is A. [tex]y=-\frac{2}{3}x+12[/tex]
Answer:
[tex]\Large \boxed{{y=-\frac{2}{3}x +12}}[/tex]
Step-by-step explanation:
y = mx + b (slope-intercept form of a line)
m is slope
b is y-intercept
The y-intercept of the line is (0, 12) or 12.
y = mx + 12
The slope of the line can be found through rise over run.
(0, 12) and (18, 0) are two points on the line.
m = (y2-y1)/(x2-x1)
m = (0-12)/(18-0)
m = -12/18
m = -2/3
The slope of the line is -2/3.
y = -2/3x + 12
What is slope - intercept form and what do the variables represent?
Answer:
Definition and Equation
This form of the equation of a line is called the slope-intercept form. The y-intercept of a line (b), is the y-coordinate of the point where the graph of the line crosses the y-axis. As we have seen in the Wild About Cupcakes example, it is the value of y when x = 0.

Answer: Hi!
Slope - intercept form is a type of equation (or formula.) It shows you how to graph a line and find the slope and y - intercept of that line.
Slope - intercept form looks like this: y = mx + b
M represents the slope of the line. B represents the y - intercept.
The y - intercept is where the line would intercept the y - axis. The slope is kind of like the angle the line is at (For example: it slopes downward.)
