Answer:

11

Step-by-step explanation:

c=\sqrt{a^{2} + b^{2} } \\14 = \sqrt{9^{2}+ b^{2}  } \\14 = \sqrt{81 + b^{2} } \\14^{2} = 81+b^{2} \\196 = 81 + b^{2} \\81 + b^{2} = 196\\b^{2} = 196-81\\b^{2} = 115\\b = \sqrt{115} \\b = 10.72\\b = 11

A textbook store sold a combined total of 343 history and chemistry textbooks in a week. The number of chemistry textbooks sold
maria [59]

Let the number of History books be x. Then:-

x + x - 59 = 343

2x = 402

x = 201

So there are 201 History books and (201 - 59) = 142 Chemistry books.

What is the value of the expression ?
zubka84 [21]

The value of this expression is 3 x 10^{6}


In order to find this, you divide each term separately. First we'll start with the numbers in the front.


\frac{4.8}{1.6} = 3


Now that we have the first number, we look to the 10s and the powers they are raised to. Since we are looking at powers of the same number, we can use the properties of exponents to simply subtract the numbers they are raised to.


\frac{10^{9}}{10^{3}}  = 10^{6}


Then we put the two back together for the final answer.


3 x 10^{6}
