Tickets for the school play sell for S4 each. Which graph shows the relationship between the number of tickets sold
Fiesta28 [93]

Answer:

Step-by-step explanation:

Tickets for the school play sell for $4 each.

Number of tickers sold = x

Total income from the tickets = y

This means when x = 1, y = 4

SO when we sell 1 ticket (x = 1),  we make $4 income (y = 4).

If we sell 2 tickets (x = 2), we will make $8 income (y = 8)

If we sell 3 tickets ( x = 3) , we will make $12 income (y = 12)

If we sell 4 tickets ( x = 4), we will make $16 income ( y =  16) etc.

Also note that when we sell 0 tickets (x = 0), we make no income (y = 0).

So if you create a graph, it should look something like this:

Solve the equation using the Quadratic Formula. x2 - 8x + 15 = 0 Select the correct choice below and, if necessary, fill in the
Ahat [919]

Answer:

x = (5,3)

Step-by-step explanation:

the quadratic formula is x =( -b±√(b^2-4ac))/2a

to solve for x, a=1, b=-8,c=15

x =( -(-8)±√((-8)^2-4*1*15))/2(1)

x=8 ± √(64-60))/2(1)

x=(8 ± √(4)) / 2

x=(8 ± 2) / 2

solve with '+'

x=(8 + 2) / 2 = 10/5 = 5

solve with '-'

x=(8 - 2) / 2 = 6/2 = 3

x = (5,3)

Some fireworks are fired vertically into the air from the ground at an initial velocity of 24.5 meters per second. Find the high
krek1111 [17]

Answer:

The highest point reached by the firework is approximately 30.6 meters

Step-by-step explanation:

The upward velocity of the fireworks is given as 24.5 m/s

The equation of projectile motion for an object fired vertically upwards can be written as follows;

v² = u² - 2·g·s

Where;

v = The final velocity of the motion = 0 m/s at maximum height

u = The final velocity of the motion =  24.5 m/s

g = Acceleration due to gravity = 9.81 m/s²

s = The height reached = (The highest point reached by the firework)

By substituting the values, we have;

(0 m/s)² = (24.5 m/s)² - 2 × 9.81 m/s² × s

Which gives;

2 × 9.81 m/s² × s = (24.5 m/s)² = 600.25 m²/s²

19.62 m/s² × s = 600.25 m²/s²

s = 600.25 m²/s²/(19.62 m/s²) = 30.594 m ≈ 30.6 meters

The highest point reached by the firework is approximately 30.6 meters

Erion plans to tile the floor of his kitchen. The kitchen is 11 feet by 15 feet. The tiles he will be using are square, measurin
Luba_88 [7]

Answer:

First, find the area for the kitchen floor: 16.5*15=247.5 squared feet

Then find the area for one tile: 0.5*0.5=0.25 squared feet

Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.

Also you can do it in this another way:

First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33

Then, do the same for the height: 15/0.5=30

Finally multyply both results: 33*30= 990 tiles.

Step-by-step explanation:

or just 990
