1. Your question tells that the percentage of the red marble in the bag is 25%. So if a child chooses 4 marbles, the probability that he could get 3 red marbles is A.0.047
2.In your question the supplier has a stock of parakeets were 10% is blue, so the chance of the supplier to deliver 1 blue parakeet out of 3 is letter B.0.243
38.4/x=100/32.5
multiple both sides of the equation by x
38.4=3.07692307692*x
divide both sides by the big number to get x
38.4/(big number)=x
x=12.48
The volume of the building would be the sum of the volume of the roof and the volume of the base
For the volume of the base, the formula is
V = lwh
Where
l = length of base = 50 feet
w = width of base = 15 feet
h = height of base = 15 feet
Volume of base = 50 * 15 * 15 = 11250 square feet
For the volume of the roof, the formula is
V = 1/2lwh
Where
l = length of roof = 50 feet
h = height of roof = 10 feet
w = width of roof = 15 feet
Volume of roof = 1/2 * 50 * 10 * 15 = 3750
Volume of buiding = 11250 + 3750 = 150000 cubic feet
Answer:

b. If a polygon has four 90 degree angles, then it is a rectangle
True
c. If the formula for a shape's area is base time height, it is a rectangle
False
You would find the common denominator which in this case is 8. You would change 1/4 to 2/8. Which means that Daniel ate 2/8 of the pie.
