Answer:
9 White marbles are present in the bag.
Step-by-step explanation:
Let the number of White marbles present in the bag be X and number of Yellow marbles present be Y .
Then according to the question ,
X + Y = 16 -(1) (As total marbles are 16)
Also,
X = 2Y - 5 -(2)
From Equation 1 , X = 16 - Y , Comparing with Equation 2 , we get,
16 - Y = 2Y - 5
3Y = 21.
Y = 7.
So, X = 16 - Y = 16 - 7 = 9.
Thus, 9 White marbles are present in the bag.
You have 20 cookies total in the jar. The probability of choosing an oatmeal is 4/20, and the probability of choosing a peanut butter cookie is 8/20. In order to find the probability of pulling a peanut butter cookie OR an oatmeal cookie, we have to add the probabilities together. 8/20 + 4/20 = 12/20 or 6/10 or 3/5. The answer is C.

Answer:
Step-by-step explanation:
1. Area of a parallelogram = base * height
area = 10 * 4 = 40 in squared
perimeter = 2(a + b)
perimeter = 2 * (5 + 10) = 2 * 15 = 30in
2. Area of triangle = 1/2 * base * height
area = 1/2 * 21 * 8 = 84 cm squared
perimeter = sum of outer perimeters
perimeter= 10cm + 17cm + 21cm = 48cm
3. area of trapezium = 1/2 * (a+b) * h
area = 1/2 * (6+12) * 4 = 36ft squared
perimeter = sum of outer perimeters
perimeter = 5ft + 6ft + 12ft + 5ft = 28ft
