20 cartons

total of eggs = 20x12=240

240------ 100%

60------ x %

x is the percentage that represents 60 cracked eggs

x=\frac{60\cdot100}{240}=25

The percent of the eggs are cracked is 25%

Answer:

27.5 mm

Step-by-step explanation:

The game piece has the shape of two identical square pyramids attached at their bases. Given that the perimeters of the square bases are 80 millimeters, and the slant height of each pyramid is 17 millimeters.

Let the side length of each of the side of the base of the pyramid be b, hence:

perimeter = 4b

80 = 4b

b = 20 mm. half of the side length = b/2 = 20 / 2 = 10 mm

The slant height (l) = 17 mm, Let h be the height of one of the pyramid, hence, using Pythagoras theorem:

(b/2)² + h² = l²

17² = 10² + h²

h² = 17² - 10² = 189

h = √189

h = 13.75 mm

The length of the game piece = 2 * h = 2 * 13.75 = 27.5 mm.

Please help i’ll give brainliest
Luba_88 [7]

In a 45 - 45 - 90 right triangle, the hypotenuse is √2 · legs = hypotenuse, so legs=\frac{\sqrt{5}}{\sqrt{2}} and to rationalize the denominator all we have to do is multiply the numerator and denominator by √2. \frac{\sqrt{10}}{2}.
