Answer:

The constant of proportionality, k is 15

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities.

Proportional quantities can be described by the equation y = kx, where k is a constant ratio.

Here, "x" is the number of tickets and "y" is the number of dollars.

k = 30/2 = 15/1 or 15

k = 15

k = 60/ 4 = 30/2 = 15/1 or 15

k = 15

k = 90/6 = 30/2 = 15/1 0r 15

k = 15

When we take the ratio of x and y for all the given values, we get an equal value for all the ratios.

Therefore, the constant of proportionality, k is 15

A hot air ballon was 240 ft above the ground. It decreased its altitude by 6 1/2 ft per min for 15 min, and then increased its a

Mekhanik [1.2K]

Part A The equation to model this would be

240-( 240- 6.5x + 9) = y

x is the minutes the balloon decreases in altitude

Part B plug in x

240- (240 - 6.5(15) + 9) = y

y = 106.5

expression answer: 106.5

Part C altitude is 133.5 (240 - 106.5)

lisabon 2012 [21]

Answer:

$3 \frac{1}{3}$

Step-by-step explanation:

We know that Sally picked 6 2/3 pounds of apples, which can be converted into an improper fraction: 20/3. Multiply 20/3 and 1/2. You will get 20/6, which is 3 1/3. Hope this helped :D

Suppose the axis of symmetry of the graph of a quadratic function is x=6 If now root of the related quadratic equation is -1.5 w

dsp73

Axis of symmetry is x = 6

One of the roots is -1.5

On the graph, -1.5 is to the left of the axis of symmetry by 7.5 units. If we were to go 7.5 units the opposite direction from the axis of symmetry (right), we would get the other root. Simply:

6 + 7.5 = 13.5

Therefore the other root would be 13.5.

Hope this helps! :)

A triangle T is bounded (on three sides) by the lines x = 6, y = 0, and y = 3 2 x. A rectangle of width w is inscribed inside T.

Viktor [21]

Answer:

33.85 units^2

Step-by-step explanation:

you must first draw the triangle on the plane using the equations (see

attached file), you will have a right angle triangle with a height of 192 and a base of 6.

then you calculate the angle with the tangent function = 88.21

Then you use the small triangle to find the value of a (see attached file).

Finally, you propose an equation for X to find one of the sides of the triangle, once you have x squared it, and you already have the area,
