360/6=60, how many 6s go into 36 to start. The answer is 6. 360 is 10x 36 so just add a 0 to 6.
Answer:
The reasoning here is that the price should be based on the volume.
for a cylinder it's pi * r² * height
for a cone it's 1/3 * pi * r² * height
you'll notice that the formulas are the same, except that the cone is just one third of the cylinders volume.
so a fair price should be 70ct, ignoring packaging of course.
We can start by eliminating y. Seeing as they already have opposite coefficients, no multiplication or division needs to be done. So, add the two equations together. 3.2x + (-1.6x) = 1.6x. 4.2 + 3.4 = 7.6. 0.5y + (-0.5y) = 0. This leaves us with 1.6x = 7.6. Now divide both sides by 1.6 to get x = 4.75.
Now we can eliminate x. Since the coefficients of x are not opposites, we need to multiply the bottom equation by 2 on both sides. That leaves us with -3.2x - y = 6.8. Now we can add both equations together. 3.2x + (-3.2x) = 0. 0.5y + (-y) = -0.5y. 4.2 + 6.8 = 11. This leaves us with -0.5y = 11. Divide both sides by -0.5 to get y = -22.
Therefore the answer is B: (4.75, -22)
Answer:
answer
Step-by-step explanation:
Here is my answer:
If one leg is x.
Then the other legs need to be longer than 7, so it is (x + 7)
x² + (x +7)² = 13²
x² + (x +7)² = 169
So I believe that is the equation.
From the Pythagorean triple of 5, 12, 13, one should and would know that if the equation above is solved, x = 5.
