Find the value of [tex]\frac{a^{2} }{a^{4}+a^{2}+1}[/tex] if [tex]\frac{a}{a^{2}+a+1}[/tex] = [tex]\frac{1}{6}[/tex]. Please show all work.

Answers

Answer 1
1/a^2+a+1 put in fraction form
Answer 2

Answer:

1/36

Step-by-step explanation:

notice the first equation is the second equation squared.

For instance, look at the numerator: a squared is a^2

Look at the denominator: a^2 squared is a^4 and so on.

So if the second equation is 1/6, then you need to square it to have it equal the second equation: (1/6)^2 = 1/36

Which property did Michaela show?
symmetric property of equality
multiplication property of equality
substitution property of equality
reflexive property of equality

Answers

The answer it’s 16 because when you supract 25 by 9 it’s will give you 16 and the p =q so q also 16
The correct answer is C) substitution property of equality.

Michaela knew that is she substituted q for p, it would still be the same equation just a different variable.

Answer:

you would take your index finger and your thumb and put them toward the eraser and move your fingers and the answer is 9 or 13 if you needed help with that

Step-by-step explanation:

Answer:

13 cm

The good news is that you don't need a ruler!

First, you see that the eraser is approximately 5 cm in length, so you must your mind to mentally picture the eraser beside it. You end up with 10 cm. Then, you see that there is more space left on the stick. You know that another complete eraser will not fill up that space. So, you must ask yourself: What is larger than 9 cm, but smaller than 15 cm? The answer is 13 cm!

What is the cost of making one burrito?

Answers

Answer:

$4.27

Step-by-step explanation:

Answer:

The cost of making one burrito is $2.50

By selling 100 burritos the restaurant would have profits of $550

Step-by-step explanation:

Since the cost of meat is $1.50 and the cost of other ingredients is $1 you add both of these together to get the total cost of making a burrito which is $2.50

In order to calculate profits you subtract 2.5 from 8 (which is 5.5) because it takes $2.5 to make a burrito

To find the total profits of selling 100 burritos you do 5.5 x 100= 550

Hello I can help you what is the math question you ask so I can help you get an A

Answer:  these are in "slope-intercept form"  y = mx + b

m is the slope.  b is the y-intercept

Start with the y- intercept, the "constant" on the right side of the equation. Plot a point there on the y-axis. Then use the slope to plot another point or two to find our where to draw the line. If there is no number for m, it is an implied 1. That means from your first point, go up 1 then 1 to the right to plot the next point

Step-by-step explanation:

When the slope is a fraction, use the denominator to find out how far to go to the right.

If the slope is negative, move down first then to the right to plot the next point.
