<u>Answer:</u>

The area of the triangle PQR is 90 cm^2.

<u>Step-by-step explanation:</u>

We are given two triangles, ABC and PQR, which are similar to each other.

If two triangles are similar, then the ratio of their areas is the square of the ratio of their sides.

Given that area of the triangle ABC is 40cm^2, we are to find the area of the triangle PQR.

Finding the scale factor k=\frac{6}{4} =1.5

So square of this scale factor will be k^2=(1.5)^2=2.25

Area of triangle PQR = 2.25 \times 40 = 90cm^2

Answer:

90cm^2

Step-by-step explanation:

The side length AB of triangle ABC corresponds to side length of PQ of triangle PQR.

The scale factor from ABC to PQR is k=\frac{6}{4}=1.5

The area of triangle PQR will change by k^2=1.5^2=2.25 centimeters square.

Since we know the area of triangle ABC to be 40cm^2, the area of triangle PQR =2.25\times 40=90cm^2

Graph this line using the slope and y-intercept: y = 1/8x + 4<br> (1/8 is a fraction)
Tems11 [23]

Answer:

Two points, (0,4) & (8,5)

Step-by-step explanation:

In this equation, we can easily find the first point by looking at the +4 in this equation. This should automatically signal to you that the point is (0,4)

Now, we have to look at the 1/8x in the equation.

This 1/8 means that the slope is 1/8!

Now we use the slope and to rise/run to find our next point

We go up 1 from 4 (this is the rise) to get to 5 on the y-axis

Next, we go over 8 horizontally to get to 8 for your x-axis point.

So therefore, our next point is, (8,5)

You can use this rise/run system infinitely and is very useful
