the last option is the correct one
Step-by-step explanation:
70, Multiply 5 pieces by 12 friends and you get 60, then add the 10 pieces he originally took out, and you get 70
Answer:
10.2% of adults will belong to health clubs and will go to the club at least twice a week
Step-by-step explanation:
assuming that the event H=an adult belongs to a health club and the event T= he/she goes at least twice a week , then if both are independent of each other:
P(T∩H)= P(H)*P(T) ( probability of the union of independent events → multiplication rule )
replacing values
P(T∩H)= P(H)*P(T) = 0.20 * 0.51 =0.102
then 10.2% of adults will belong to health clubs and will go to the club at least twice a week
So, since there are two equations, we can substitute one of them into the other. In this case, it would be easiest to substitute 2b=6a-14 into the other equations. But first, simplify by dividing both sides by 2. You bet b=3a-1
We can now plug this into the other equation
Sine the equation b=3a-1 results in the value of b, we have to plug in for the value of b in the other equation
So this is what we get after plugging in:
3a-(3a-1)=7
Now, simplify. 3a-3a+1=7
Since 3a-3a = 0, this equation results in a no solution
Answer:
The result is a no-solution, or Ф
Hope this helped!! :D
He had put in $300 and got out $336 at the end of the year.
This means an increase of $36 over a year.
10% of $300 = $30 dollars
This shows that he definitely got more than a 10% increase.
Alan got $6 more than $30 so to find 6 from 30, you divide by 5
so ( 10% = $30 ) divided by 5 = ( 2% = $6 )
Adding the amount of money and percentages gives you 12% = $36
So the amount of mpercentage increase is 12%
Overall the amount of money in his bank now compared to when he deposited it, he has 112% in the bank.
