A cashier is unsure whether a group of customers ordered and ate a large or a medium pizza. Medium pizzas have a diameter of 12
Vinvika [58]
Answer: large pizza

Work:


1) You can determine the arc of a slice that is 1/12 of the whole pizza using the diameter.

2) First, calculate the total circumference of each pizza.

Formula for the circumference: 2π×radius

radius = diameter / 2

medium pizza: 2π (12 / 2) = 12π ≈ 37.70 in

large pizza: 2π (16/2) = 16π ≈ 50.27 in

3) arc of a 1/12 sector

arc of a 1/12 sector = circumferece × 1/12

medium pizza: 37.70 in / 12 = 3.14 in


large pizza: 50.27 in / 12 = 4.19 ↔ this is pretty close to 4.25


So, at the end we have found that the sector of 4.25 in left belongs to a large pizza.

11a) False. If you simplify 8/30 you get 4/15 not 2/15.

11b) False. If you simplify 6/15, you get 2/5 not 3/5.

11c) true. 5/15 can be simplified to 1/3.

X^2-5x-6<br> X^2+3x-40<br> X^2+3x-4
luda_lava [24]

x² - 5x - 6

= x² + x - 6x - 6

= x(x + 1) - 6(x + 1)

= (x - 6) (x + 1)

x² + 3x - 40

= x² + 8x - 5x - 40

= x(x + 8) -5(x + 8)

= (x - 5) (x + 8)

x² + 3x - 4

= x² + 4x - x - 4

= x(x + 4) -1(x + 4)

= (x - 1) (x + 4)

3x+4y+z=-2<br> 2y+3z=-8<br> z=-3
masya89 [10]

Answer:

z=-3 so 2y+3(-3)=-8, 2y-9=-8, add 9 to both sides 2y=1 divide both sides by 2, y=1/2, so 3x+4(1/2)+-3=-2, 3x+2-3=-2, 3x-1=-2, add 1 to both sides, 3x=-1, divide both sides by 3, x=-1/3
