Explain how to decompose a triangle into congruent triangles. How does the area of those decomposed triangles relate to the area of the rectangle?

Answers

Answer 1

So for any triangle, you can divide it into four congruent triangles by connecting the midpoints of each side. You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

Answers

Answer:

1. 30 metres

2. 27 squared feet,

3. 25.13 cm

4. 50.27 sqared inches

5. 15.71 metres

6. 380.13 squared metres

7. Area is: 4.52 squared metres Circumference is: 7.54 metres

8. Circumference is: 47.12 feet Area is: 176.71 squared feet

Step-by-step explanation:

1. Since you're rounding pi, your calculation would be:

2 × 3 × 5 = 30

---------------------------------------------------------------------------------------------------------------

2. Since you're rounding pi, it would be:

3 × 3² = 27

---------------------------------------------------------------------------------------------------------------

3. Use the formula for number 5

---------------------------------------------------------------------------------------------------------------

4. Use the formula in number 6

---------------------------------------------------------------------------------------------------------------

5. Formula for the circumference of a circle is:

[tex]C=2\pi r[/tex]

So:

2 × 3.14 × 2.5 = 15.71

---------------------------------------------------------------------------------------------------------------

6. Formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

So:

3.14 × 121 = 380.13

---------------------------------------------------------------------------------------------------------------

7. Use the formula for numbers 5 and 6 to figure these out

---------------------------------------------------------------------------------------------------------------

8. Use the formula for 5 and 6, except divide the diameter by 2 because the formula only works with the radius

Answers

Answer:

Step-by-step explanation:

A is 50 and B is 10

then, C is 5

50+10=60

50-10=40

50÷10=5

have a nice day

Answer:

Step-by-step explanation:

A+B=60

A=60-B

substitute the value of A in

A-B=40

60-B-B=40

60-40=2B

20/2=B

10=B

Now, substitute the value of B in

A+B=60

A+10=60

A=60-10

A=50

A/B=C

50/10=C

5=C

Lisa went on a 52km hike. She divided the distance traveled evenly over 4 days.

How many meters did Lisa walk each day?

Answers

Answer:

52km divided by 4 = 13000m

Step-by-step explanation:

52 kilometers divided by 4 days is 13000 meters

4 days hike = 52km
1 day hike = 52/4
= 13km

1 km = 1,000m
13km = (13 x 1,000)
= 13,000m

Therefore Lisa walked 13,000 metres each day on her 4 day hike.

Hope this helps. :)

There are a few reasons thay Tammy's

Additionally, she was asking students from

hope this helped qwq

katie can draw 182 pictures in 312 minutes.

first, we should find out how many pictures she can draw in 1 minute. 14/24 equals 0.583333... pictures per minute. 0.583333... times 312 equals 182 pictures (i used a calculator so this should be correct). hope this helps!
