Answer:

15%

Step-by-step explanation:

Formula to find percentage increase/decrease/multiplier:

NV = OV x m

In words: New value = Old value x multiplier

In this question we're looking for the m (multiplier), so rearrange the formula and make m the subject.

m = NV / OV

So NV is the increase: 3162.50

OV = 2750

So 3162.50 / 2750 = 1.15

This is the multiplier (1.15) so turn into percentage by multiplying by 100 then subtract by 100.

1.15 * 100 = 115 - 100 = 15%

And the fact that the number is postive is proof that price has increased, if it was decrease, you would be expecting a negative number. Hope you understood. :)

Which relationship is always true for the angles x, y, and z of triangle ABC?

noname [10]

Answer:

y + z = x

Step-by-step explanation:

Let's rename angle BAC to w. Now, we have four angles: w, x, y, and z. We know that w + y + z has to equal 180 degrees, because a triangle's three angels always adds up to 180 degrees. We also know that w + x equals 180 degrees, because they are on the same line. These two phrases are equal:

w + y + z = w + x

We can then cancel w on each side:

y + z = x

Hope this helps! :)
