Answer:
If your asking us to just combine like terms it would be -3b^2-2b^2+1.4b+4c+c
but if your asking us to answer the question it would be -5b^2+1.4b+5c
Hope I helped :)
72 inches is 6 feet, and there are 5280 feet in a mile, so you divide 5289 by 6 to get 880 rotations per mile
The answer I would say would be B.
Step-by-step explanation:
Add everything and then equate it to 360 and when you have found x, substitute it in A and B
Answer:
Required probability = 7/75.
Step-by-step explanation:
Probability(purple marble) = 7/15 (as there are 7 marbles out of a total of 15.)
Probability( red marble) = 3/15 = 1/5.
So the probability of a purple being drawn followed by a red marble
= 7/15 * 1/5
= 7 /75 (answer).
Note: the 2 probabilities are multiplied because the 2 draws are independent of each other.
