Answer:
20 cm² & 80 cm²
Step-by-step explanation:
Ratio of areas = (ratio of sides)²
Ratio of sides: 2/4 = ½
Ratio of areas: (½)² = ¼
Areas are:
⅕(100) = 20
⅘(100) = 80
Answer:
Step-by-step explanation:
The 8
It goes tenths hundredths then thousands
Answer:
First: 1/4
Second: 3/5
Step-by-step explanation:
FIRST:
You can easily solve this problem by creating a slope triangle between the points given.
1 up
———————- = 1/4
4 to the right
SECOND:
To solve for slope with two points, you do y1-y2/x1-x2.
1-4 -3
—— = — = 3/5
-3-2 -5
Answer:
<em>Choice B. 16 feet.</em>
<em>The height of the tree is 16 ft</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Similar triangles have their corresponding side lengths proportional by a fixed scale factor.
We are given the drawings of a tree and a wall and it's assumed both triangles are similar. We need to find the scale factor and find the height of the tree.
Comparing the corresponding distances from the viewer to the base of the tree and the base of the wall, we can calculate the scale factor as 24/6=4.
Applying the same factor to the height of the model, we get the height of the tree is 4*4 = 16 ft.
Choice B. 16 feet
The height of the tree is 16 ft
That is the centroid.
The point where the lines from each vertex of the triangle to the midpoints of the opposite sides intersect.
