Answer

You make all the denominators to 12.

That makes Gilbert the fastest and Simon the slowest.

First thing you do is make all the denominators the same, these can all be multiplied up to 12.

8/12 11/12 10/12 7/12

Next thing you gotta do is find the fastest and slowest, ( the names don't matter because we are not identifying the fastest and slowest, only the difference ) 11/12 and 4/12

Last, we needa subtract these two to get our answer.

11/12 - 7/12 = 4/12 or 1/3

Answer: 11/10 or 1 1/10 pages

Step-by-step explanation:

3/5 + 1/2 = x

find the LCD so that you can add the fractions.

3/5 (2/2) = 6/10

1/2 (5/5) 5/10

6/10 + 5/10 = 11/10 or 1 1/10

Derivative of<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7B3x%7D%5E%7B2%7D%20-%202x%20-%201%20%7D%7B%20%7Bx%7D%5E%7B2

Anastaziya [24]

Answer:

$\displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3}$

Step-by-step explanation:

we would like to figure out the derivative of the following:

$\displaystyle \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} }$

to do so, let,

$\displaystyle y = \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} }$

By simplifying we acquire:

$\displaystyle y = 3 - \frac{2}{x} - \frac{1}{ {x}^{2} }$

use law of exponent which yields:

$\displaystyle y = 3 - 2 {x}^{ - 1} - { {x}^{ - 2} }$

take derivative in both sides:

$\displaystyle \frac{dy}{dx} = \frac{d}{dx} (3 - 2 {x}^{ - 1} - { {x}^{ - 2} } )$

use sum derivation rule which yields:

$\rm\displaystyle \frac{dy}{dx} = \frac{d}{dx} 3 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2}$

By constant derivation we acquire:

$\rm\displaystyle \frac{dy}{dx} = 0 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2}$

use exponent rule of derivation which yields:

$\rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ - 1 -1} ) - ( - 2 {x}^{ - 2 - 1} )$

simplify exponent:

$\rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ -2} ) - ( - 2 {x}^{ - 3} )$

two negatives make positive so,

$\displaystyle \frac{dy}{dx} = 2 {x}^{ -2} + 2 {x}^{ - 3}$

<h3>further simplification if needed:</h3>

by law of exponent we acquire:

$\displaystyle \frac{dy}{dx} = \frac{2 }{x^2}+ \frac{2}{x^3}$

simplify addition:

$\displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3}$

and we are done!

Kyle plays softball. His goal is to have a batting average of .400 or greater by the end of the season. The ratio that relates t

gregori [183]

Answer:

The number of hits is $T \ge 30 \ hits$

Step-by-step explanation:

From the question we are told that

The ratio of the number of hits to the number of chances is equivalent to the batting average

The number of chances is j = 65 + 10 = 75

The number of hit so far is n = 25

Generally the batting average can be represented mathematically as

$A = \frac{n + k}{ j}$

Here k is the number of additional hits Kyle need to get in order to obtain the batting average of 0.40 or more

$\frac{25 + k}{ 75} \ge 0.40$

=> $k \ge 5 \ hits$

Hence the number of hits for Kyle to get a batting average of 0.400 or greater by the end of the season is

$T \ge k + n$

=> $T \ge 5 + 30$

=> $T \ge 30 \ hits$
