Answer:
A.16b^4/81
step-by-step explanation:
(2b/3)^4
= (2b)^4/3^4
= (2^4×b^4)/3^4
=16b^4/81
(as 16 and 81 cant simplify each other)
Assuming number cube has 6 sides
probablity is (desiredoutcomes)/(total possible ouctomes)
since it is 450 times
total possible outcomes=450
experimiental probablity is the one actaully obtained by doing it
theoretical is the predicted amount
so theoretical probablity of rolling a 3 is 1 number out of 6 or 1/6 or 75 times out o 450 times
experimiental is the actaull one so67 out of 450 or 67/450
theoretical is 1/6 or 75/450
experimental is 67/450

Answer:
50 ft
Step-by-step explanation:
The side lengths in a 30-60-90 triangle have the ratios 1 : √3 : 2. The longest side is 2 times the length of the shortest side.
In this geometry, that means the length of the escalator is 2 times its height, so is ...
x = 2(25 ft)
x = 50 ft . . . . . distance a person travels
Answer: The answer is 652.8
Step-by-step explanation:
First, one dozen cupcakes is 12.. So do 12*2=24 to get two dozen cupcakes.
Next, do 27.2*24=652.8
Answer:
6. B
7. D
Step-by-step explanation:
For 6 found that the 56 pieces in the first bag was about 18% of that bag. So then I found that 18% of 450 is ruffly 84, so B
For 7 I multiplied 5x5 is 25 so then 50x5 is 250, which is D
