They buy 8 orchestra seats and 6 mezzanine seats

Step-by-step explanation:

For a production of Sweeney Todd in Las Vegas

Orchestra seats cost $42
Mezzanine seats cost $25
A group of 14 people show up and spend a total of $486

We need to find how many of each kind of seat they bought

Assume that the group of people takes x orchestra seats and y mezzanine seats

∵ The group of 14 people show up

∵ x represents the number of orchestra seats

∵ y represents the number of mezzanine seats

∴ x + y = 14 ⇒ (1)

∵ Orchestra seats cost $42 each

∵ Mezzanine seats cost $25 each

∵ The group of people spend a total of $486

∴ 42 x + 25 y = 486 ⇒ (2)

Now we have system of equations to solve it

Multiply equation (1) by -25 to eliminate y

∵ -25 x - 25 y = -350 ⇒ (3)

- Add equations (2) and (3)

∴ 17 x = 136

- Divide both sides by 17

∴ x = 8

Substitute the value of x in equation (1) to find y

∵ 8 + y = 14

- Subtract 8 from both sides

∴ y = 6

They buy 8 orchestra seats and 6 mezzanine seats

A map of Levi’s property is being made with a scale of 1 centimeters: 2 meters. What is the scale factor?

vodka [1.7K]

Answer:

200

Step-by-step explanation:

I started by having the same units on both sides of the expression:

1 m = 100 cm

1cm = 2(100cm)

I then simplified the equation to find the scale:

1cm = 200cm

Answer:

Case 1: a = 1.5, b = 2, c = -3

$D = 22$

Case 2: a = 2.3, b = -4, c = 1

$D = 6.8$

Case 3: a = 3.7, b = 9, c = -4

$D = 140.2$

Case 4: a = 4.6, b = -8, c = 5

$D = -28$

Case 5: a = 5.5, b = 7, c = -3

$D = 115$

Case 6: a = 6.9, b = -5, c = 2

$D = -30.2$

Case 7: a = 7.2, b = 6, c = -4

$D = 151.2$

Case 8: a = 8.3, b = -3, c = 4

$D = -123.8$

Case 9: a = 9.9, b = 4, c = -7

$D = 293.2$

Case 10: a = 10.4, b = 8, c = -5

$D = 272$

Step-by-step explanation:

For all second order polynomial, the discriminant is equal to:

$D = b^{2}-4\cdot a \cdot c$

Case 1: a = 1.5, b = 2, c = -3

$D = 22$

Case 2: a = 2.3, b = -4, c = 1

$D = 6.8$

Case 3: a = 3.7, b = 9, c = -4

$D = 140.2$

Case 4: a = 4.6, b = -8, c = 5

$D = -28$

Case 5: a = 5.5, b = 7, c = -3

$D = 115$

Case 6: a = 6.9, b = -5, c = 2

$D = -30.2$

Case 7: a = 7.2, b = 6, c = -4

$D = 151.2$

Case 8: a = 8.3, b = -3, c = 4

$D = -123.8$

Case 9: a = 9.9, b = 4, c = -7

$D = 293.2$

Case 10: a = 10.4, b = 8, c = -5

$D = 272$
