Josiah subtracts 337 from 600 and writes the following
600 minus 300 is 300. Then I can subtract 40 more and get 260. But I should have only subtracted 37

If f(x) = 5 + 4x^2, then f(3) =

Answers

Answer:

f(3) = 41

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

f(3) = 41

Answers

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.

On average, which country user's spend the most time on social media? Which country's users spend the least time?

Answers

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.

If the Perimeter of the triangle 15 centimeters, what is the value of n

Answers

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

How to determine the value of n?

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

Answers

Answer:

E(x) = 40x² + 2150x - 500E(36) = $128740

Step-by-step explanation:

Earnings = A(x)Savings = S(x)Expenses = E(x)

Savings = Earnings - Expenses Expenses = Earnings - Savings

E(x) = A(x) - S(x)E(x) = 2400x + 40x² - (250x + 500) E(x) = 2400x + 40x² - 250x - 500 E(x) = 40x² + 2150x - 500

E(3 years) = E(36 months)

Solve the equation for the indicated variable. A=r+rvf, for v

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:

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]

A contractor is tiling the bottom of a round fish pond with 1-inch square tiles that cost $0.12 each. the fishpond has a diameter of 30 inches. how much will he spend on tiles?

Answers

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
