Divide and simplify. √36 x⁴ / √9 x⁶

Mathematics
1 answer:
Vikki [24]1 year ago
7 0

The divide and simplify of the equation √36 x⁴ / √9 x⁶ will result to  \frac{2}{x^{2} }

Let's begin by simplifying the equation;

Simplify the equation by finding the square root of both 36 and 9

The square root of 36= 6

The square root of 9= 3

= \frac{6x^{4} }{3x^{6} }

The above equation can also be written as;

=  6x^{4}  * 3x^{-6}

The next step is to solve the powers, that is,

=   \frac{6x^{4} }{3x^{6} }

Cancel out 6 by 3 and get  2

The result is,  

=  \frac{2}{x^{6-4} }

The final submission result is,

=  \frac{2}{x^{2} }

We often deal with weighted​ means, in which different data values carry different weights in the calculation of the mean. For​
Veseljchak [2.6K]

Answer:

a) The student's overall average for the class is 87.97.

b) He would need a score above 100 to get an A, which means that he could not have scored high enough on the final exam to get an A in the class.

Step-by-step explanation:

Weighed average:

To solve this question, we find the student's weighed average, multiplying each of his grade by his weights.

Grades and weights:

Scored 82.5 on the midterm, worth 30%.

Scored 88.6 on the final exam, worth 30%.

Scored 91.6 on the homework, worth 40%.

a. On a 100-point scale, what is the student's overall average for the class?

Multiplying each grade by it's weight:

A = 82.5*0.3 + 88.6*0.3 + 91.6*0.4 = 87.97

The student's overall average for the class is 87.97.

b. The student was hoping to get an A in the class, which requires an overall score of 93.5 or higher. Could he have scored high enough on the final exam to get an A in the class?

Score of x on the final class, and verify that the average could be 93.5 or higher. So

A = 82.5*0.3 + 88.6*0.3 + 0.4x

A \geq 93.5

82.5*0.3 + 88.6*0.3 + 0.4x \geq 93.5

0.4x \geq 93.5 - (82.5*0.3 + 88.6*0.3)

x \geq \frac{93.5 - (82.5*0.3 + 88.6*0.3)}{0.4}

x \geq 105.425

He would need a score above 100 to get an A, which means that he could not have scored high enough on the final exam to get an A in the class.

Solve following <br> x-y=2<br> 5x+3y=18
kvasek [131]
X-y = 2
5x+3y =18 

let do some plug and play 

x-y = 2 
x = 2+y
now we got an answer for x lets plug that in the other equation

5(2+y) + 3y = 18
10+5y + 3y = 18
10 + 8y = 18
8y = 8
y = 1 

now lets find x 
x = 2 +y 

x = 2+ 1 
x = 3.
