Answer:
4x^-4/9y^6
Step-by-step explanation:
If the exponent is outside the bracket, it means that all the terms inside will be raised to that exponent. This means that:
(2x^-2 / 3y^3)^2 = 2^2*(x^-2)^2 / 3^2*(y^3)^2
When exponents are raised to an exponent, the exponents are multiplied together, so (x^-2)^2 will = x^(-2*2) = x^-4
Going through:
2^2*(x^-2)^2 / 3^2*(y^3)^2
=4*x^-4 / 9*y^6
=4x^-4/9y^6

If M is the midpoint of XY, XM=2x+5 and YM=25, find XY.
Answers
Answer:
50
Step-by-step explanation:
Since M is the midpoint of XY, this means that XM and MY must be equivalent from the definition of midpoint.
So:
[tex]XM=MY[/tex]
The entire length of the segment (XY) is:
[tex]XY=XM+MY[/tex]
We know that XM is equivalent to MY. Substitute MY for XM:
[tex]XY=MY+MY[/tex]
Combine like terms;
[tex]XY=2MY[/tex]
We are told that YM (or MY) is 25. So:
[tex]XY=2(25)[/tex]
Multiply:
[tex]XY=50[/tex]
So, the length of XY is 50.
And we're done!

In a certain grocery store, strawberries cost $4.96 per pound ( 4.96 dollars/lb d o l l a r s / l b ). What is the cost per ounce?
Answers
Cost of the strawberry will be $0.31 per ounce.
Given in the question,
Strawberry cost → $4.96 per poundWe can write the cost as [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}[/tex].
Since, 1 pound = 16 ounces
To convert the cost of the strawberry in dollars per ounce, multiply the price by the conversion factor [tex]\frac{1\text{ Pound}}{16\text{ Ounces}}[/tex].
So the cost of strawberry = [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}\times \frac{1\text{ Pound}}{16\text{ Ounces}}=0.31\text{ Dollars per ounce}[/tex]
Therefore, cost of the strawberry will be $0.31 per ounce.

What is the perimeter of the triangle?
Answers
The perimeter of the triangle is 36 units.
Distance
The distance between two points A(x₁, y₁) and B(x₂, y₂) is given by:
[tex]AB=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
The coordinate of the triangle is A(0, 0), B(10, 0) and C(5, 12). Hence:

The answer is -153/35 I just need to know how to get that
Answers
Answer:
[tex]y=-\dfrac{153}{35}[/tex].
Step-by-step explanation:
The given equation is
[tex]0.15(y-0.2)=2-0.5(1-y)[/tex]
Using distributive property, we get
[tex]0.15(y)+0.15(-0.2)=2-0.5(1)-0.5(-y)[/tex]
[tex]0.15y-0.03=2-0.5+0.5y[/tex]
[tex]0.15y-0.03=1.5+0.5y[/tex]
Isolate variable terms.
[tex]0.15y-0.5y=1.5+0.03[/tex]
[tex]-0.35y=1.53[/tex]
Divide both sides by -0.35.
[tex]y=\dfrac{1.53}{-0.35}[/tex]
[tex]y=-\dfrac{1.53}{0.35}\times \dfrac{100}{100}[/tex]
[tex]y=-\dfrac{153}{35}[/tex]
Therefore, [tex]y=-\dfrac{153}{35}[/tex].
In Triangle ABC, the length of Segment AB is equal to the length of segment AC. The length of segment BC is 4 less than twice the length of segment AB. If the perimeter of Triangle ABC is 52, find the length of segment AB.
Answers
Step-by-step explanation:
Let x be the length of segment AB.
Then the length of segment BC is (2x - 4).
The length of segment AC is x.
We know that x + (2x - 4) + x = 52.
Therefore 4x - 4 = 52, 4x = 56, x = 14.
Hence the length of segment AB is 14.

Answers
Answer:
Let's define x as the number of text messages send.
y as the number of 1,000 minutes talk per month.
(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.
> The equation for Dash is:
C1(x, y) = $80
>The equation for AB&C
C2(x,y) = $0,20*x + $55*y
> Horizon
C3(x,y) = $0.10*x + $75*y.
Now, which company you should go for?
Well, it depends on the values of x and y that you have.
if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.
if you usually talk, you may want to go with AB&C because the slope for y is smaller.
If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

what is 0.142857 repeating as a fraction????
Answers
Answer:
Step-by-step explanation:
[tex]n= 0.142857[/tex]
[tex]1000000n= 0.142857[/tex]
Move the decimal point using the 1000000n
You should get 142857.142857 repeating
Subtract n from both sides [tex]142857.142857- 0.142857[/tex]
You should get 142857 without the repeating decimal.
The equation is now: [tex]142857/999999[/tex] (fraction)
A cool trick to find out if you can reduce that is: [tex]1+4+2+8+5+7[/tex] (equals 27) is the answer to that addition a number divisible by three (yes). So the number 142857 is divisible by 3 which means that you can simplify the fraction.
You can use a calculator for 142857/3 (division) (unless your teacher says you can't)
You should get 47619
You should get[tex]47,619/333333[/tex] (fraction).
I think you can divide that by 3 again. [tex]4+7+6+1+9[/tex] is 27, which is divisible by 3.
Again, you can use a calculator for 47619/3 (division) (unless your teacher says you can't)
You should get 15,873
You should get 15,873/111111 (fraction)
The repeating decimal 0.142857 is equivalent to the fraction 1/7.
Given that we need to convert a repeating decimal 0.142857 as a fraction.
The repeating decimal 0.142857 can be expressed as a fraction. To understand how to convert it, let's denote it as x:
x = 0.142857...
To convert this repeating decimal to a fraction, we can multiply x by a power of 10 to shift the decimal point and eliminate the repeating part.
Since there are six digits in the repeating block (142857), we can multiply x by 10⁶ to remove the repeating part:
10⁶ · x = 142857.142857...
Next, we subtract the original equation from the one above to eliminate the repeating part:
(10⁶ · x) - x = 142857.142857... - 0.142857...
Simplifying the equation:
999999x = 142857
Now, we can solve for x by dividing both sides of the equation by 999999:
x = 142857 / 999999
Simplifying the fraction:
x = 1 / 7
Therefore, the repeating decimal 0.142857 is equivalent to the fraction 1/7.
