Amy purchased a large rectangular box with a base that measures 50 meters by 30 centimeters with a height of 20 centimeters. Amy wants to fill the box with ½ meter cubes. How many cubes will Amy use to fill the box?

600 Ice cubes

Step-by-step explanation:

Given that :

Height of box = 20 cm

Dimension of base = 50cm * 30cm

Volume of box :

Dimension of base * height

50 * 30 * 20 cm³

= 30,000 cm³

Size of ice cube = 0.5m = 0.5 * 100 = 50 cm

Number of ice cubes :

30,000 / 50

= 600 ice cubes

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

⇒ option b is correct.
