Answer:3.46
Step-by-step explanation:
In a piggy bank, 40% of the coins are dimes.
3/8 of the remainder are nickels.
The remainder is going to be 60%
1/8 of 60% is 7.5%. (just dividing by 8)
3/8 of 60% = 7.5% × 3 = 22.5% are nickels.
If 22.5% are nickels, then 77.5% are not.
The percentage of coins that aren't nickels is the same as the probability of drawing one because each coin has equal probability to be chosen.
I think it's A. y = 2/3x - 5
Answer:
Okay so I am assuming you mean the third part?
Step-by-step explanation:
Pretty simple. So you see that the varible x^2 does not have a number in front of it, so there is no extra dividing.
A formula for a perfect square is (x^2)+2xy+y^2
Take 10 and divide it by 2.
10/2=5
You have Y. Finding the third part is squaring Y.
5^2=25
Therefore, the third part of the perfect square is 25. If you want to find Y, look at the stuff above.
