Let us assume that the number of days she practiced the piano to be "d"
Since she practiced 2/3 hours a day, the total number of hours would be: 2/3*d
Now we are given the total number of hours during summer that she practiced be be equal to 32/23
So we equate 2/3 * d to 32/23 to find d
2/3*d = 32/23
d = (32/23)/ (2/3)
d = (32/23) * (3/2)
d = 48/23 hours
The equation that can be used to find the number of days that she practiced piano during the summer is 2/3*d = 32/23
Answer:
1) a = 0
Step-by-step explanation:
Taking logarithms base 2, we have ...
-3a·log2(1/8) = 3a·log2(512)
-3a(-3) = 3a(9)
27a -9a = 0 . . . . . . . subtract 9a
a = 0/18 = 0 . . . . . . divide by 18
The solution is a = 0.

![\frac{1}{208}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B208%7D)
Step-by-step explanation:
We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.
Let us find probability of getting a club.
![\text{ Probability of getting a club}=\frac{13}{52} =\frac{1}{4}](https://tex.z-dn.net/?f=%5Ctext%7B%20Probability%20of%20getting%20a%20club%7D%3D%5Cfrac%7B13%7D%7B52%7D%20%3D%5Cfrac%7B1%7D%7B4%7D)
Now let us find probability of getting the ace of spades.
![\text{ Probability of getting ace of spades}=\frac{1}{52}](https://tex.z-dn.net/?f=%5Ctext%7B%20Probability%20of%20getting%20ace%20of%20spades%7D%3D%5Cfrac%7B1%7D%7B52%7D)
Now let us multiply these to find probability of getting a club and ace of spades.
Therefore, probability of getting a club and then the ace of spades
