Decreased by 25%
find 25% of 12 and decrease 12 by it

percent means parts out of 100
25%=25/100=1/4
'of' means multiply
25% of 12=1/4 times 12=3

decrease 12 by 3
12-3=9

answer is 9

first turn 25% into a decimal so it's easier to work with, the decimal for 25% is 0.25

then multiply the number by the decimal

12x0.25=3

then subtract your answer (3) from your starting number

12-3=9

12 dogs decreased by 25% leaves you with 9 dogs left.


if you are increasing, divide instead of multiply

31 and 81 are in the bottom corners of the triangle X is at the top . What is X?
kati45 [8]

Answer:

The top angle of the triangle is, X = 68°.

Step-by-step explanation:

Let there is a triangle named PQR with bottom corner angles ∠ P and ∠ Q and the ∠ R is the angle at the top.

Now, given that ∠ P = 31° and ∠ Q = 81° and we have to find out ∠ R i.e. X.

In Δ PQR, we know, ∠ P + ∠ Q + ∠ R = 180°

⇒ 31° + 81° + X = 180°

⇒ X = 68°

Therefore, the top angle of the triangle is 68°. (Answer)

How does the diagram show that the slope between any
tensa zangetsu [6.8K]

The diagram shows that the triangles on the graph had similar ratios, as such their vertical heights to their horizontal are equivalent.

Option D is correct.

<h3>What is the slope of a graph?</h3>

The slope of a graph determines the steepness of the graph and it is the difference between two points on the y-coordinate(rise) and the difference between two points on the x-coordinate(run).

\mathbf{slope = \dfrac{rise}{run}}

\mathbf{slope = \dfrac{\Delta y}{\Delta x}}

\mathbf{slope = \dfrac{ y_2-y_1}{x_2-x_1}}

From the diagram attached, we can see that the triangles on the graph had similar ratios, as such their vertical heights(y-coordinates) to their horizontal (x-coordinates) are equivalent.
