3/5+1/3

common denominator is 15 ( just think about the 3 times table and 5 times table )

5*3=15

3*5=15

Multiply the denominator and numerator by 3 for 3/5

Multiply the denominator and numerator by 5 for 1/3

(3)(3)/(5)(3) +(1)(5)/3(5)

9/15+5/15= 14/15

Answer : 14/15

The perimeter of a rectangle is 46cm. The length is 13 cm. What is the width?
gladu [14]
1.) 2 sides are already gonna be 13 so you already have 26 is you add up both those sides.  13+13=26
2.)Subtract 26 from 46 to get the sum of both the widths added together.
    46-26=20
3.)Divide 20 by 2 so that you can get the width on one side of the rectangle.              20 / 2 = 10
4.) The width of the rectangle above is 10
                                                I hope this helps :)

kipiarov [429]

Answer: I would say 5 days.

Step-by-step explanation:

I added both days together and divided by 2 because there are two individuals working on 20 trees and divided equally it would be 10 and it would take 5 days because that’s half.

Please answer asap will give brainiest
lubasha [3.4K]

Answer:

79% - almost 4 times out of 5.

The key to this is realizing that the number of games will not always be 5.

If A wins in a sweep - you have 2/3*(2/3)*2/3 percent chance of that happening - 8/27, or 29.63%

If A wins in 4, now we have 2/3*(2/3)*2/3*(1/3)*3 - the 1/3 is the chance that B wins a game. Note - there are only 3 ways B can win a game, not 4. B cannot win Game 4 because Game 4 would not be played in case of a sweep. That is why you cannot use a straight Pascal’s triangle to get your coefficients - the 1–4–6–4–1 is not possible if B cannot win Game 4. Anyway, the math is the same as the above, a 29.63% chance of A winning in 4.

For a 5 game set, A could lose 2 games in 6 possible ways (lose 1&2, 1&3, 1&4, 2&3, 2&4 or 3&4). Again, A cannot lose Game 5 - it would not be played once A wins 3 games. So the odds become 2/3*(2/3)*2/3*(1/3)*(1/3)*6, or 19.75%.

Add them up and you get 79.01%

Step-by-step explanation:

Hope it helps<3
