Use the correct order of operations to evaluate the following expression:(5+4).5+3.3
horsena [70]

Answer:

For any mathematical expression follow the BODMAS rule which states that we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).

Step-by-step explanation:

(5+4) × 5 + 3.3

Bracket open = 9

Since there is no division, so multiply 9×5, which is 45

Then add, 45+3.3

Answer= 48.3

Hey!

Hope this helps...

If a paper is 4/1000 inches think, how many of them will it take to equal 1000?

Well... if we take 1000 divided by 4 we get 250.

So 250 sheets of paper would be 1 inch thick...

what is the order from least to greatest - 4 with the exponent of 3, square root of 40, square root of 13, square root of 7, , 1
LuckyWell [14K]

Answer: -4^{3} , 14/9 , \sqrt{7} , \sqrt{13} , \sqrt{40}

Step-by-step explanation:

-4^{3} = - 64

\sqrt{40} = 6.32455532

\sqrt{13} = 3.605551275

\sqrt{7} = 2.645751311

14/9  = 1.555555556

Arranging from least to greatest , we have :

-4^{3} , 14/9 , \sqrt{7} , \sqrt{13} , \sqrt{40}
