Answer:

r = 11

Step-by-step explanation:

Add 5 to both sides of the equation:

6 + 5 = r - 5 + 5

Add the numbers

11 = r - 5 + 5

11 = r

Move the variable to the left

r = 11

The diameter of a pizza is 14 inches. What is the circumference of the pizza? Tell you what value you used for pi
Allisa [31]
The formula for finding circumference is C=2*pi*r. So C is the circumference that you are trying to find. Pi is 3.14. And r is the radius. Now, it does not tell you directly what the radius is, but the diameter of a circle is basically how far across is it. So in this case, 14. The radius of a circle is half of it's diameter, so half of 14 is 7. So, multiply 2*3.14*7, to get the circumference. You get 43.96.

In each box is a step in the process of solving a max/min problem like the one in Question 8. Number these steps in order (1-8)
Dmitriy789 [7]

Answer:

The steps are numbered below

Step-by-step explanation:

To solve a maximum/minimum problem, the steps are as follows.

1. Make a drawing.

2. Assign variables to quantities that change.

3. Identify and write down a formula for the quantity that is being optimized.

4. Identify the endpoints, that is, the domain of the function being optimized.

5. Identify the constraint equation.

6. Use the constraint equation to write a new formula for the quantity being optimized that is a function of one variable.

7. Find the derivative and then the critical points of the function being optimized.

8. Evaluate the y-values of the critical points and endpoints by plugging them into the function being optimized. The largest y- value is the global maximum, and the smallest y-value is the global minimum.

10 x 5 thousands standard form
jeka94

Answer: 10*5,000=50,000

Step-by-step explanation:

By definition, when you multiply two factors the result is known as "Product".

In this case you have to solve the following multiplication:

10*5\ thousands

The first factor is already written in Standard form, but the second one is not written in Standard form.

Then, you need to rewrite it in numbers:

5\ thousands=5,000

Therefore, the product is:

10*5,000=50,000

Find the product. If the result is negative, enter "-". If the result is positive, enter "+". -7(- a2 ) 2 ( -b3 ).
m_a_m_a [10]

Answer:

The product is positive, thus it is \bold{+7a^4b^3}

Step-by-step explanation:

The full question in proper notation is:

"Find the product. If the result is negative, enter "-". If the result is positive, enter "+".

-7(-a^2)^2(-b^3)"

We have to work with it using Order of operations know as well as PEMDAS, thus expression inside parenthesis go first and exponents.

On this expression we have to work with exponents

(-a^2)^2 = (-a^2)(-a^2) =a^4

Thus we get

-7(-a^2)^2(-b^3)=-7a^4(-b^3)

Lastly we can work with multiplication and remembering that the multiplication of two negative signs becomes positive.

-7(-a^2)^2(-b^3)=7a^4b^3

So the final simplified expression is \bold{7a^4b^3}
