Answer:
Step-by-step explanation:
Given the information of the conical hat
- diameter of 16 inches => Radius = 8 inches
- height of 9 inches
=> the slant height of the hat is (use Pythagorean Theorem)
= 
<=> = 
<=> s = 
The area (without the base area) of tissue paper will she need to make one hat is:
SA = πrs in2
<=> SA = π*8* in2
<=> SA =8 π
=> the total tissue paper will she need for 21 hats is:
SA*21
= 8 π*21
= 6352,18 in 2
Answer:
The digit '0' is in the ones place.
There are an infinite number of 3 number sets that will equal 9000, unless your looking for whole numbers.
If you want to find a set of whole numbers, first break 9000 into its factors:
5 * 5 * 5 * 3 * 3 * 2 * 2 * 2 = 9000
Now to find a set of 3 numbers, just combine some of the factors.
For example:
(5 * 5 * 5) * (3 * 3) * (2 * 2 * 2) = 9000
125 * 9 * 8 = 9000
Hello there!

Hope this helped! :D
Answer:
The second one, question 4, would be C, y = -2x + 16
Step-by-step explanation:
You're trying to make an equation out of the information on the graph.
So, start with the format y = mx + b.
The variable m represents the slope. Use rise/run. I chose to use the points (0, 16) and (2, 12).
You would end up with a rise over run that looks like this: 4/2. Simplified, the slope would be 2. Because this line is moving downwards, your slope is negative.
So far, you have y = -2x + b.
The variable b represents the initial value, or where the line first touches the y-axis. You can see that the initial value is 16.
Plug that in. y = -2x + 16.
Hope this helps! Sorry I couldn't answer both, good luck on that test! <3
