Tyler paid $16 for 4 raffle tickets.5.
What is the price per ticket?6.
How many tickets is that per dollar?
Answer:
$4/ticket; .25ticket per dollar
Step-by-step explanation:
Tyler paid $16 for 4 raffle tickets.
Part 1: What is the price per ticket?
Part 2: How many tickets per dollar?
For part 1, you will divide $16 by 4 tickets.
16/4=4
You can get 4 tickets for $16 so that's $4/ticket.
For part 2, you already know that it is $4 for one ticket. The question wants to know how many tickets you will get for $1. To find this answer you will divide 1 by 4.
4/1 = .25
So you can get .25 of a ticket per dollar.
Colton is making gift bags. He has 120 small prizes, and puts 3 in each gift bag. He also has 75 larger prizes,and puts 2 in each gift bag. Write the function f(x) that represents how many prizes Colton has left aftermaking x gift bags.
Answer: f(x) = 195 - x*5
Step-by-step explanation:
Colton has 120 small prizes and 75 larger prizes.
Then at the start, he has 120 + 75 = 195 prizes.
In each bag, he puts 3 small prizes and 2 larger prizes, then in each bag there are 3 + 2 = 5 prizes.
Then if he fills x bags, he will have: x*5 fewer prizes, then we can write the equation f(x) as:
f(x) = 195 - x*5
Where when x = 0, this means that he filled zero bags, then he has the initial amount of prizes, 195.
Simplify : - sqrt(- 75) A. - 5i * sqrt(2) B. - 5i * sqrt(3) C. - 5i D. 5i
Answer:
B
Step-by-step explanation:
Here, we want to calculate the square root of -√- (75)
That will be
-√(25)(-3)
= -5 √(-3)
√(-3) is same as 3i
So we have the root as;
-5i√3
Identify the pair of points that can represent an increasing function that has a greater rate of change than that of the function Y=8/5x+ 3/5
Answer:
A general lineal equation is written as:
y = a*x +b
Where a is the slope (also called the rate of change) and b is the y-intercept-
For a line that passes through the points (x1, y1) and (x2, y2)
The slope will be:
a = (y2 - y1)/(x2 - x1)
For the line:
Y= (8/5)*x+ 3/5
The slope, or rate of change, is 8/5.
Then we want to find two points (x1, y1) and (x2, y2) such that the slope generated by them is larger to 8/5.
There are a lot of ways to finding these points, a simple way is:
We could define (x1, y1) = (0, 0)
And (x2, y2) = (5, 9)
Then the rate of change of the line that passes through these two points will be
a = (9 - 0)/(5 - 0) = 9/5
Which is larger than 8/5, as we wanted.
In order to join a hip-hop dance crew, there is a 30$ initiation fee and a 4$ monthly fee. If you were to write an expression to represent the situation, what is the constant

y = 4x + 30 ends up being your equation and a constant is the # without a variable. That is why the constant would be 30.
Determine the value of z for the system of equations. x + y + z = 2 3x - 2y + 2z = -8 8z - 12y - x = 12
Answer:
4Step-by-step explanation:
To get the value of z, we need to reduce the system of equation into two and 2 unknowns;
Add 1 and 3:
y - 12y + z + 8z = 2+12
-11y + 9z = 14 ....... 4
Also Multiply equation 1 by 3 and subtract from 2
Eqn 1 * 2 will give 3x + 3y + 3z = 6
Subtract from eqn 2;
3y-(-2y)+3z-2z = 6-(-8)
5y+z = 14 ....5
Solve 4 and 5
-11y + 9z = 14 * 5
5y+z = 14 * 11
________________
-55y + 45z = 70
55y + 11z = 154
Add both
45z+11z = 70+154
56z = 224
z= 224/56
z = 4
Hence the value of z is 4

Step-by-step explanation:
Area of a Rectangle
Given a rectangle of width W and length L, its area is calculated by the formula:
A = W.L
We are given three rectangle-shaped figures and are required to find different measures as explained below.
1. Length L=94 ft, Area = 4,700 square ft
We'll find the width by solving for W:
[tex]\displaystyle W = \frac{A}{L}[/tex]
[tex]\displaystyle W = \frac{4,700}{94}[/tex]
W = 50 ft
2. A=8,250 square m, W=75 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{8,250}{75}[/tex]
L = 110 m
3. A=1,586 square m, W=26 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{1,586}{26}[/tex]
L = 61 m

A stone is thrown vertically upwards with an initial velocity 20m/s. Find the maximum height it reaches and the time taken by it to reach the height.
(g= 10m/s)
who gives answer with explanation i will make him braillint
Answer:
The maximum height it reaches is 20 meters
The time taken by it to reach the height is 2 seconds
Step-by-step explanation:
The formula of the height of the stone is h = u t - [tex]\frac{1}{2}[/tex] g t², where
t is the time to reach the height hu is the initial velocityg is the acceleration of gravity∵ A stone is thrown vertically upwards with an initial velocity of 20 m/s
∴ u = 20 m/s
∵ g = 10 m/s²
→ Substitute them in the equation above
∴ h(t) = 20t - [tex]\frac{1}{2}[/tex] (10) t²
∴ h(t) = 20t - 5t²
→ Arrange the terms of the right side according to the greatest power of t
∴ h(t) = -5t² + 20t
To find the maximum height and the time of it find the vertex of the quadratic function (m, k), where m = [tex]\frac{-b}{2a}[/tex] and k is the value of h at t = m, a is the coefficient of t² and b is the coefficient of t
∵ The coefficient of t² is -5
∴ a = -5
∵ The coefficient of t is 20
∴ b = 20
→ Use them to find h
∵ m = [tex]\frac{-20}{2(-5)}[/tex] = [tex]\frac{-20}{-10}[/tex] = h
∴ m = 2
→ Substitute it in the equation above to find k
∵ h(m) = k
∵ k = -5(2)² + 20(2)
∴ k = -5(4) + 40
∴ k = -20 + 40
∴ k = 20
∴ The coordinate of the vertex of the function are (2, 20)
→ m represents the time of the maximum height and k represents
the maximum height
∴ The maximum height it reaches is 20 meters
∴ The time taken by it to reach the height is 2 seconds

The endpoints of u are 0 (-2,9) and A(6,-3). What is the length of segment ?
A 14.5
B 14.4
C 14
D 13.9
Answer:
[tex]B.\ 14.4\ units[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\Coordinates\ of\ Endpoint\ O=x_1,y_1=(-2,9)\\Coordinates\ of\ Endpoint\ A=x_2,y_2=(6,-3)\\As\ we\ know\ that,\\The\ length\ of\ line\ segment\ OA\ or\ u\ is\ the\ distance\ between\ its\ endpoints\\ O\ and\ A.\\Hence,\\The\ linear\ distance(d)\ between\ any\ two\ points\ on\ a\ cartesian\ plane,\\ is\ given\ by\ the\ Formula:\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\Hence\ here,\\[/tex]
[tex]In\ order\ to\ find\ the\ distance\ between\ O\ and\ A,\ we\ just\ need\ to\ plug\ in\\ its\ respective\ coordinates\ in\ the\ Formula\ above.\\Hence,\\Distance\ between\ O\ and\ A= \sqrt{(6-(-2))^2+(-3-(9))^2} \\Distance\ between\ O\ and\ A= \sqrt{(6+2)^2+(-3-9)^2}\\Distance\ between\ O\ and\ A= \sqrt{(8)^2+(-12)^2}\\Distance\ between\ O\ and\ A= \sqrt{64+144}\\Distance\ between\ O\ and\ A= \sqrt{208}\\Distance\ between\ O\ and\ A \approx 14.42\ or\ 14.4\ units[/tex]
