(4xy^3+8x^2y^5)/(2xy^2)  Since 2xy^2 is a common factor we have

2y+4xy^3

2y=2x^ay^b

x^0=x^a

a=0

Suppose that 7 cards are drawn from a? well-shuffled deck of 52 cards. What is the probability that all 7 are heartshearts?
elena55 [62]
There are 13 hearts in the deck of 52.
If we want to simply choose 7 of them, we use combinatorics, and not permutations.

Thus, the total number of ways to choose 7 of the 13 hearts, is: ¹³C₇ or 1716 ways.
The total in our sample space is simply choosing 7 of the 52 cards, which is: ⁵²C₇ or 133 784 560.

Thus, the probability becomes:
\frac{1716}{133784560} = \frac{33}{2572780}

Sonji has $5.25 in nickels and dimes.The coin value can be modeled by the equation 0.10 d plus 0.05 n equals 5.25, where d repre
Ira Lisetskai [31]

Answer:

To find the number of nickels and dimes, we can use this equation: 0.10d + 0.05n = 5.25

We are given the information that Sonji has 21 dimes (which means that d=21). We can use the equation to find the number of nickels n.

0.10d + 0.05n = 5.25

0.10(21) + 0.05n = 5.25

2.10 + 0.05n = 5.25

0.05n = 3.15

n = 3.15 / 0.05

n = 315 / 5

n = 63

Sonji has 63 nickels.

Let's check our answer.

21(0.10) + 63(0.05) = 2.10 + 3.15 = 5.25

It seems that our answer is correct.
