Answer:

10. ○\displaystyle 4,85; 4\frac{17}{20}

9. ○680%

8. ○40%

7. ○\displaystyle 60

6. ○0,4, 40,5%, 11⁄25, 4⁄9

5. ○\displaystyle 0,928

4. ○1%

3. ○76%

2. \displaystyle See\:above\:grid

1. \displaystyle See\:above\:grid

Step-by-step explanation:

10. To convert from a percentage to a decimal, move the decimal mark twice to the left; each 20 is worth 5, and since 5 by 17 is 85, you have your fractional part of 17⁄20, then attach the whole number of 4.

9. To convert from a mixed number\improper fraction to a percentage, first evaluate the fractional part for a decimal answer, then move the decimal mark twice to the <em>right</em>.

8. To convert from a fraction to a percentage, evaluate the fraction for a decimal answer, then move the decimal mark twice to the right.

7. \displaystyle \frac{132}{220} = \frac{3}{5} =60%

Greatest Common Divisor [GCD]: 44

6. \displaystyle \frac{11}{25} =44%

_

\displaystyle \frac{4}{9} =44,4%

\displaystyle 0,4 =40%

Now that these are all percentages, it is alot easier to order them from least to greatest.

5. To convert from a percentage to a decimal, move the decimal mark twice to the <em>left</em>.

4. To convert from a decimal to a percentage, move the decimal mark twice to the <em>right</em>.

3. Each 25 is worth 4, and since 4 by 19 is 76, you get 76%.

2. Each 25 is worth 4, and since 4 by 6 is 24, you get 24%, and this graph.

1. Each 36 is worth 2 7⁄9, and since 12 by 2 7⁄9 is 33⅓, you get 33⅓%, so you would choose this answer.

I am joyous to assist you anytime.

given that BD is both the median and altitude of triangle ABC, congruence postulate SAS is used to prove that triangle ABC is wh
stira [4]

Answer:

Isosceles

Step-by-step explanation:

Consider triangle ABC, BD is the median and the altitude drawn to the side AC. This segment (BD) divide the triangle ABC into two triangles: ABD and CBD.

In these triangles:

  • AD=DC (because BD is the median);
  • ∠ADB=∠CDB=90° (because BD is the altitude);
  • BD is common side.

Thus, by SAS postulate, triangles ABD and CBD are conruent. Congruent triangles have congruent corresponding sides. Hence, AB=CB.

If in triangle ABC, AB=BC, then this triangle is isosceles.
