Answer:
The area of base of cereal box is 20 mm².
Step-by-step explanation:
The volume of a cereal box is 400 mm³. The height of bx is 20mm.
The volume of box is
Divide both sides by 20.
Therefore the area of base of cereal box is 20 mm².
Answer:
8/49
Step-by-step explanation:
Given data
Sample space
4 red marbles
8 blue marbles
2 green
Sample size
4+8+2 = 14
Pr(picking a red)
Pr(red)= 4/14= 2/7
With replacement
Pr(picking a blue)
Pr(blue)= 8/14= 4/7
Hence the probability of picking a red marble, replacing the item, and then picking a blue marble
= 2/7*4/7
= 8/49

Answer:
x = √53
Use the pythagorean theorem to solve for x, which would be c in the equation a^2 + b^2 = c^2.
(a and b are the sides that meet up in a right triangle, c is the hypotenuse. In this case, you are solving for the hypotenuse.)
Step-by-step explanation:
1. Plug in the numbers in the pythagorean theorem.
2^2 + 7^2 = c^2 (remember, each variable is squared)
2. Simplify.
4 + 49 = 53
Since each variable in the pythagorean theorem is squared, the side value would be √53.
You just have to add. Ex AC you would add them and see if it's the same if you add DF
