Answer:

First, we have to find slope. We do that by using slope formula. Once we have found slope, we have start to write our equation in slope-intercept form. To get the complete equation, we need to find the y-intercept. To do so, we simply plug in one of the coordinates given to us into our half-formed equation. We should be able to find the y-intercept and then have our complete linear equation once we write it all out.

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: $m = \frac{y_2-y_1}{x_2-x_1}$

Two triangles are similar. The perimeter of the smaller one is 16. The ratio of the corresponding sides is 2:5. The sides of the

Eddi Din [679]

Answer:

Perimeter of larger triangle is 40.

Step-by-step explanation:

Given:

Perimeter of smaller circle = 16

Ratio of corresponding side = 2:5

We need to find the perimeter of the larger triangle.

Solution:

Let the perimeter of the larger triangle be 'x'.

Therefore by theorem which states that;

" When a triangle have scale factor a:b then the ratio of the perimeters is a:b".

Here Ratio is 2:5, so we can say by theorem, Ratio of perimeters is 2:5

framing in equation form we get;

$\frac{\textrm{Perimeter of smaller triangle}}{\textrm{Perimeter of Larger triangle}}=\frac{2}{5}$

Substituting the values we get;

$\frac{16}{x}=\frac{2}{5}$

By Cross multiplication we get;

$16\times 5=2x\\\\80=2x$

Dividing both side by 2 we get;

$\frac{80}{2}=\frac{2x}{2}\\\\x=40$

Hence Perimeter of larger triangle is 40.

AleksAgata [21]

Answer:

A.) 40(t) = E

B.) 520

Step-by-step explanation:

t is for time, E is the total, H is the hourly rate.

plug in the numbers to get 40(13) = h and solve for H and you get 520

If you can do this please answer it.

denis23 [38]

Your answer would be rounded about 140 because first rectangle =108divided by 9 = 12 which was the the perimeter of the rectangle plus the 90 degree right triangle which was about 36 so there.
