Which is the graph of y<2x-1

Answer:

Every integer is a rational number. Numbers like 1/2, 454/242, and -6/9 are also rational because they are fractions whose numerator and denominator are integers. All in all, a rational number is any number that can be written as a simple fraction.

Answera=frv+r

Step-by-step explanationa=r+rvf

To solve for a variable in an equation means that we change the subject of the formula. The solution to the equation for variable v is:

[tex]\frac{A - r}{rf} = v[/tex]

Given that:

[tex]A = r + rvf[/tex]

Subtract r from both sides

[tex]A - r = rvf[/tex]

Divide both sides by rf

[tex]\frac{A - r}{rf} = v[/tex]

Rewrite as:

[tex]v=\frac{A - r}{rf}[/tex]

Hence, the solution to the equation for variable v is:

[tex]\frac{A - r}{rf} = v[/tex]

Answer:

about $3.60

Step-by-step explanation:

Because it's a round pond and the tiles are square they might be cut a little but the main point of the question would be the 12 cents PER tile. Per is the one of the words to show multiplication. So you multiply .12 x 30 to get 3.6 and since this is money it would be $3.60

Hope that helps and have a great day!

Answer: $84.78

Step-by-step explanation:

If the bottom of the fish pond is round which means it has to be a circle, and to find the space that needs to be covered,you need to find the area of the bottom of the pond.

So it has a diameter of 30  and to find the area you need to find the radius,square it and multiply it by pi.  

The radius will be 15 because the radius is half the diameter.

A= 15^2 * 3.14   we will use 3.14  as an approximation for pi.

A= 225 * 3.14

A= 706.5  

Now after you have find the area multiply it by the amount of money that each tile cost to fin the total amount of money you have to pay.

706.5 * 0.12= 84.78

So approximately you will spend $84.78 on tiles

Answer:

Step-by-step explanation:

f(x) = 5 + 4x²

To find f(3) substitute the value of x that's 3 into f (x) which means for every x in f (x) replace it with 3

That's

f(3) = 5 + 4(3)²

= 5 + 4( 9)

= 5 + 36

We have the final answer as

Answer:

Israel  top,  canada bottom

Step-by-step explanation:

Don't worry, I have this question too :)

Answer:

On average, Israel's country's users spend the most time on social media. United States' country's users spend the least time.

Step-by-step explanation:

Using the given inputs, we will rewrite these as decimals.

The only fractions that are listed are:

United States - 7 3/5

Canada - 7 7/10

Russia - 10 2/5

Colombia - 8 1/2

To convert a fraction to a decimal, we have to divide the numerator to the denominator. Add this decimal number to the whole number part of the mixed number.

So now, we get:

United States - 7.60

Canada - 7.70

Russia - 10.40

Colombia - 8.50

To determine which ones are greater than the others, you add a 0 to the end of the decimal.

The number with the least value here is 7.6, and the number with the largest value is 10.4. So, Israel's country's users spend the most time on social media. United State's country's users spend the least time on social media.

a) The graph II will tell the greatest sample standard​ deviation.

and, the least sample standard​ deviation is given by Graph III.

b)  The three data sets have same mean, median and mode but different

standard deviation.

The term "standard deviation" (or "[tex]\sigma[/tex]") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

From the Graph we can say the the dispersion of data from the mean tells about the Standard deviation.

Then, the graph II will tell the greatest sample standard​ deviation.

and, the least sample standard​ deviation is given by Graph III.

b)  The data sets have same mean but different standard deviation.

So, The three data sets have same mean, median and mode but different

Answer:

Step-by-step explanation:

n+2n+1+5n-6=15

= 8n + 1 - 6= 15

= 8n + 1 - 6 + 6 = 15 + 6

= 8n +1 = 21

= 8n + 1 - 1 = 21 - 1

=8n = 20

= 8n / 8 = 20 / 8

= n = 2.5

the value of ‘n’ is 2.5

The value of n in the triangle is 2.5

The perimeter of the triangle is the sum of its side lengths.

So, we have:

P = n + 2n + 1 + 5n - 6

Evaluate the like terms

P = 8n - 5

The perimeter is 15.

So, we have:

8n - 5 = 15

Add 5 to both sides

8n = 20

Divide by 8

n = 2.5

Hence, the value of n is 2.5

Answer to part A:  11w^2+7z^2

Answer to part B:  14w^2+9w

=================================================

Explanation:

For part A, the expression 4w^2+7w^2+7z^2 has one pair of like terms. That pair is 4w^2 and 7w^2 which combine to 11w^2. You add the coefficients to get 4+7 = 11, then tack w^2 onto everything to say 4w^2+7w^2 = 11w^2

We cannot combine 11w^2 and 7z^2 as they aren't like terms. So we leave it as 11w^2+7z^2

--------------------

In part B, the like terms are 15w and -9w. They combine to 15w-9w = 6w. You can think of it like 15-9 = 6 then stick a 'w' to each term. We cannot combine the w^2 term with the w terms.
