Mathematics
1 answer:

Answer:

E started with 26 books, sold 13 books, bought 17 more books, and ended with 30 books

Step-by-step explanation:

E has _ books: x

E Sells 1/2 of that _ books: x/2

E buys 17 books and now had 30: (x/2) + 17 = 30

30 - 17 = 13

13 x 2 = 26

x/2 = 26

13 + 17 = 30       <-- checking work

My guess is that x = 13

Answer:

4cm^2

Step-by-step explanation:

First we need to find the length of the height of the triangle using Pythagoras:

a^2+b^2=c^2 (Substitute in what we have)

a^2+3√2(^2)=2√5(^2)   =   a^2 + 18 = 20 -> 20-18=2 √2=BD

Now we can find the area:

AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4

In a bag are three red marbles and three white marbles. If
Alexeev081 [22]

The probability is 1/5.

<h3>How to find the probability?</h3>

There are 3 red marbles and 3 white marbles, for a total of 6.

The probability that the first marble is red is:

P(red) = 3/6

The probability that the second marble is also red is:

P(red') = 2/5 (because now there are 2 red marbles and a total of 5).

The joint probability is:

P = (3/6)*(2/5) = 1/5

Please solve it. It will help me for my exam preparation. ​

The solution of the given expression is [p^{2}(p-y)^{y-1} (p-y)^{y-2} -2p(p-y)^{y} (p-y)^{y-2} +7(p-y)^{y} (p-y)^{y-1}]/  (p-y)^{y} (p-y)^{y-1}(p-y)^{y-2}

Given p^{2} /(p-y)^{y} -2p/(p-y)^{y-1} +7/(p-y)^{y-2}

We have to solve the above expression.

We know that expression is a combination of numbers, symbols, variables and coefficients, indeterminants. Expression shows relationship between variables. LCM is the smallest number that is divisible by both the numbers whose LCM has been taken. Coefficients are present in the beginning of variables. Symbols are arithmetic signs like addition, subtraction, multiplication and division, etc.

We have to take LCM of the expression and solve accordingly so that the expression can be solved =

p^{2} /(p-y)^{y} -2p/(p-y)^{y-1} +7/(p-y)^{y-2}=  [p^{2}(p-y)^{y-1} (p-y)^{y-2} -2p(p-y)^{y} (p-y)^{y-2} +7(p-y)^{y} (p-y)^{y-1}]/  (p-y)^{y} (p-y)^{y-1}(p-y)^{y-2}

Hence the expression  p^{2} /(p-y)^{y} -2p/(p-y)^{y-1} +7/(p-y)^{y-2} is equal to = [p^{2}(p-y)^{y-1} (p-y)^{y-2} -2p(p-y)^{y} (p-y)^{y-2} +7(p-y)^{y} (p-y)^{y-1}]/  (p-y)^{y} (p-y)^{y-1}(p-y)^{y-2}
