Answer:
$19.68
Step-by-step explanation:
To find out how much it'll cost Melissa to buy the ribbon, we simply need to find all the side lengths (the perimeter) and then multiply then by the cost.
We already know two of the side lengths: 6 and 8. To find the third, remember that the question tells us that the triangle is a right triangle. Therefore, we can use the Pythagorean Theorem. The unknown side is the longest side. Therefore:
Substitute 6 for a and 8 for b. This gives us:
Solve for c. Square the values:
Add:
Take the square root of both sides:
Therefore, our unknown side is 10 feet.
Therefore, the sum of our side lengths or the perimeter is:
Add:
This means that the total cost will be:
Multiply. The foot/feet cancel:
Multiply:
So, it will cost Melissa a total of $19.68 to buy the ribbon.
And we're done!

Answer:
y = -2x + 5
Step-by-step explanation:
Looking at the line, every time it moves one unit to the right, it goes down two units. Therefore, the slope is -2. Since the y-intercept is 5, the equation of this line is y = -2x+5.
I hope this helped!

6, the formula is (b1+b2/2)*h
8+12/2=10
10*h=60 so h=6
