Answer:

1. Area = 78.5 (using 3.14 as pi)

2. Circumference = 31.4 (using 3.14 as pi)

Step-by-step explanation:

Area=r^2\pi \\Circumference = 2r\pi

The radius is equal to 5 yd. We can use this information to find the are and the circumference. Let's find the area first!

A=(5)^2\pi\\A=25\pi \\A= 78.5

So, the area of the circle is 78.5 yd²

Now, let's find the circumference!

C=2(5)\pi \\C=10\pi \\C= 31.4

So, the circumference of the circle is 31.4 yd

Consider -q > 5. Use the addition and/or subtraction property of inequality to solve.
AleksandrR [38]

The correct answer would be -5 > q

In order to solve this using only addition and subtraction, what we need to do is change the side each term is on. This will allow us to get the variable to be a positive number.

-q > 5 ----> Subtract 5 from both sides

-5 - q > 0 -----> Add q to both sides

-5 > q

What is the answer to:
velikii [3]
Weird way to write it but alright! (Sideways) 

19pq^-2 x 5pq^6 = ?

These problems are pretty much single operations between each of the variables / constants. 

So it's like this: 

(19*5)(p*p)(q^-2*q^6) = ?

19*5 is 95.

For p*p remember that when two variables multiply there given powers add. In the case where the powers are not shown (like in the case of p*p) they are always assumed to be 1. So what is 1+1? 2. 

p*p is p^2

For q^-2*q^6 it is the same deal with the previous problem. So now the problem looks like this: 

-2 + 6 = 4 
(The two is negative, because the power is negative 2) 

So, q^4. 

Our final answer is all of the combined.... like a so: 

95p^2q^4

Answer:

6/0

Step-by-step explanation:

Step 1: Label your x and y's

(0,-11) (0, 5)

x1 y1  x2 y2

Step 2: Plug in your x1, x2, y1, and y2 into the slope formula

The slope formula is y1 -y2/ x1 - x2

-5-(-11)/ 0 = 6/0
