Answer:

1 7/20

Step-by-step explanation: 3/4+3/5 as a mixed number

Well you start by having 3/4+3/5 and then you multiply 5 times 3 which is 15, then you multiply 3 times 4 is 12. Now you multiply the denomerators which are 5 times 4 is 20 so what I did was I switch the number to on each side so the denomerators are 5 and 4 so I just put the 4 on the left side and then I put the 5 on the other side well you do numerator and the denomerator as the same number so you can multiply the numerator and the denomerator as the same on each side but so like this 5/5 * 3/4+3/5*4/4 now you multiply the numerator adn the denomerator anad you get 15/20+12/20 now you just add so 15+12 is 27 and you just leave the denomerator alone so it is 27/20 so now you have to divide. here is a trick up my sleeve you could do the football long division so you put it like 27/20. So now you have to figure out what can go into 27 with 20 which is 1 so you put that above the division sign and now you subtract 27 and 20 so that gives you 7 now you take that 7 and bring it above the 20 and not you have 7/20 and now you bring it up over and past the 1 and now you have 1 7/20 or you could say as like this one and seven 20 and can't 20th so I just put 20 so don't mind. I hope this is the answer!!

sukhopar [10]

Answer:

Faisal will receive $ 241
Ahmed will receive $ 482
Walid will receive $ 723.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Profit Ahmed, Walid and Faisal made from selling used books = $ 1,446

Ahmed to receive double amount of Faisal

Walid to receive triple amount of Faisal

2. How much does each one receive?

Let x to represent the amount Faisal to receive
Let 2x to represent the amount Ahmed to receive (double amount of Faisal)
Let 3x to represent the amount Walid to receive (triple amount of Faisal)

Therefore, we have:

x + 2x + 3x = 1,446

6x = 1,446

x = 1,446/6

x = 241 ⇒ 2x = 482 ⇒ 3x = 723

Faisal will receive $ 241, Ahmed will receive $ 482, and Walid will receive $ 723.

Answer:

a) An event with probability 0 is said to be impossible

b) An event with probability 1 is said to be certain

c) The probability of getting a head when flipping an unbiased coin is shown by the letter A

Step-by-step explanation:

a) If something has a 0 on a probability scale, it will never happen. The word used to describe this outcome is impossible.

b) If something has a 1 on a probability scale, it will always happen. The word used to describe this outcome is certain.

c) The probability of getting a head on an unbiased coin is $\frac{1}{2}$ or $0.50$ . This means that we are looking for the letter that is in the exact center of 0 and 1. It can be seen that A is in the dead center of these two numbers, so this is our answer.

Hey there! :D

1. 7.6 repeating ____ 55 squared

Find 55 squared.

7.6 < 3025

7.6 is less than 7.4.

2. We already know we have 11 as the whole number.

When you have a repeating decimal, you can keep it as a fraction but use 99 as the denominator.

42/99 with the 11 whole number is the answer.

3. -31/6, -5, -5/6, -26^2 <== least to greatest.

-31/6= -5.16667 -26^2= 676

4. I think the 50 is the square root. Everything else can be represented as a fraction or ratio. The square root of 50 is irrational, and cannot be represented by a fraction or ratio. 50 squared is the one that doesn't belong.

I hope this helps!
