Answer:
Cost of Pizza for 1 inch radius is $0.5.
The Direct variation between cost of pizza and radius in inches of pizza is
Step-by-step explanation:
Given:
Cost of 6 inch pizza = $3.00
We need to find the direct variation equation to represent cost of pizza with a 1 inch radius.
Let Cost f Pizza be represented by 'C'.
Also radius in inches of pizza be represented by 'r'.
First we will find Cost of pizza for 1 inch radius.
Now 6 inch pizza = $3.00
So 1 inch Pizza = Cost of pizza for 1 inch radius.
By Using Unitary method we get;
Cost of pizza for 1 inch radius =
Cost of Pizza for 1 inch radius is $0.5.
Hence We can say the direct variation would be given as;
Hence The Direct variation between cost of pizza and radius in inches of pizza is
Answer: plot a point at (-8, -5)
The y coordinate flips from positive to negative, or vice versa, when we reflect over the horizontal x axis. The x coordinate stays the same.
The rule can be written as
You will need a graduated scale and you measure.. it will be something like x ≈ 5.2 or 5.3 approximately
You can see in the picture below what you need to find. It is the red point in the picture
Good luck
Answer:
There are a lot of combinations possible
Step-by-step explanation:
One of them would be that each roll of quarters is $10 and each roll of pennies is 50cents so she could have 12 rolls of quarters and 2 rolls of pennies
