Multiply. (-5 5/8) • (-2 1/3) What is the product?

lions [1.4K]

Answer:

105/8 = 13 1/8 = 13.125

Step-by-step explanation:

The first step is to turn the (-5 5/8) into a mixed number. The mixed number you should be getting is - 45/8. The second step is to convert the (-2 1/3) into a mixed number as well, your second mixed number should be -7/3. Next multiply the two fractions, - 45/8 x (-7/3) = 315/24.

We can simplify 315/24 by dividing by 3, so you'll divide 315 divided by 3 and 24 divided by 3 and you should get ... 105/8. So 105/ 8 is equal to

13 1/8. If you need this fraction in decimal form it is 13.125.

SOMEBODY HELP ME WITH THESE PLEASE! I really need the help like NOW PLS!

93. $g(n) = n - 4$
$f(n) = 2n^2 - 5n$

then $g(n) +f(n) = (n-4) + (2n^2 - 5n)$
                                $= n - 4 + 2n^2 - 5n$
                                $= 2n^2 -5n + n - 4$
                                $= 2n^2 - 4n -4$

95. $f(n) = -n+3$
      $g(n) = n^3 + 3n$
Then $f(n) . g(n) = (-n+3) . (n^3 + 3n)$
                                 $= -n^4 + 3n^3 - 3n^2 + 9n$

97. $f(x) = 3x+1$
$g(x) = 2x$
For finding f(g(x)) we will plugin value of g(x) in place of x in f(x).
$f(g(x)) = 3*(2x) + 1$
                  $= 6x + 1$

99. $f(n) = n - 3$
$g(n) = 2n^2 - 3n$

$g(-7) = 2*(-7)^2 - 3 * (-7) = 2* 49 + 21 = 98 + 21 = 119$
$f(g(-7)) = 119 - 3 = 116$

About 2/25 Of the population of the world lives in North America.Of the population of the world lives in North America It's abou

Reil [10]

Answer:

$\frac{11}{20}$

Step-by-step explanation:

Let x is the total population of the world.

Therefore, by the condition given the population of North America is $\frac{2x}{25}$

Again it is given that $\frac{11}{250}$ fraction of the world's population lives in the United States of America.

So, $\frac{11x}{250}$ is the population of USA.

Therefore, the fraction of the population of North America that is the population of USA will be $\frac{\frac{11x}{250} }{\frac{2x}{25} } =\frac{11}{20}$ (Answer)
