The side-lengths of a triangle are decreased by a scale factor of 3. Predict

tamaranim1 [39]

ANSWER:

After changing the side lengths of the triangle are decreased by scale factor of 3, the perimeter of triangle also decreased by 3

SOLUTION:

Given, the side lengths of a triangle are decreased by a scale factor of 3.

Let the side lengths of the given triangle be a, b, c.

After the side lengths are decreased by a scale factor of 3.

Now, the side lengths will become $\frac{a}{3} , \frac{b}{3} , \frac{c}{3}$

Before changing the side lengths, perimeter of the triangle is p = a + b + c.

After changing the side lengths, perimeter of the triangle is $\frac{a}{3}+\frac{b}{3}+\frac{c}{3}$

$=\frac{a+b+c}{3}$

$=\frac{p}{3}$

So, the perimeter is also decreased by the scale factor of 3.

Hence, after changing the side lengths of the triangle are decreased by scale factor of 3, the perimeter of triangle also decreased by 3.

At higher elevations water boils at lower temperatures. The temperature at which water boils is called the boiling point of wate

Leya [2.2K]

B(x) = 100 - 3.5x
84 = 100 - 3.5x
3.5x = 100 - 84 = 16
x = 16/3.5 = 4.6 kilometers

96 = 100 - 3.5x
3.5x = 100 - 96 = 4
x = 4/3.5 = 1.1 kilometers

Therefore, the boiling point of water is between 84°C and 96°C at elevations of between 4.6 kilometers and 1.1 kilometers.
