Lexi has planted seeds in 3/5 of the garden. She used 1/2 pound of the seeds. How many pounds will she use for the entire garden
postnew [5]

Answer:

She will use 5/6 pound for the entire garden

Step-by-step explanation:

Here, we want to know the total number of pounds that will be used for the full garden.

Firstly, she used 1/2 or 0.5 pound for 3/5 of the garden, let the total amount of pound she will use for the full garden be x.

0.5 pound = 3/5 garden

x pound = 1 garden

x * 3/5 = 0.5 * 1

x * 3/5 = 0.5

3x/5 = 0.5

3x = 5 * 0.5

3x = 2.5

x = 2.5/3 or 5/6 pound

bulgar [2K]
A square has all the sides being equal.
Since the top can fit 3 color tiles, then the side must fit the same number of tiles.
Therefore, 3 roles and 3 columns of tiles will be required.
The number of tiles required will calculated similar to area of a square. That is,

Number of tiles = 3*3 = 9 tiles.

ou find a deck of cards and know that the deck has too many clubs and spades in it. The deck has 59 cards. If you were to draw t
sashaice [31]
We can find the number of extra clubs in the deck from the given probability, since the probability of drawing a diamond and a club is

\dfrac{\binom{13}1\binom{13+c}1}{\binom{59}2}=\dfrac{13(13+c)}{1711}

but this would imply that c=-4, which suggests we're taking 4 clubs out of the original deck and contradicts the problem statement that there are "too many clubs".

Perhaps the question is providing the probability of drawing a diamond, THEN a club, or vice versa. In that case, we have

\dfrac{\binom{13}1}{\binom{59}1}\cdot\dfrac{\binom{13+c}1}{\binom{58}1}=\dfrac{13(13+c)}{3422}

and solving gives c=5, which makes more sense. Then the number of extra spades in the deck must be 2.
