What is 33 1/3% of 123 I need help - 1

Answers

Answer 1
Answer: 33 1 / 3 = ( 33 * 3 + 1 ) / 3 = 100 / 3;
33 1 / 3 % = ( 100 / 3 ) / 100 = 1 / 3 ;
33 1 / 3 % of 123 = ( 1 / 3 ) * 123 = 41.
Answer 2
Answer:

Answer:

Step-by-step explanation:

33 1 / 3 = ( 33 * 3 + 1 ) / 3 = 100/3

33 1 / 3 % = ( 100 / 3 ) / 100 = 1/3

33 1 / 3 % of 123 = ( 1 / 3 ) * 123 = 41

City Park is in the shape of a regular pentagon.Each side of the pentagon is 2/5 mile long.What is the perimeter of City Park?

Answers

so you have 5 sides you can add 2/5+2/5+2/5+2/5+2/5 = 10/5 = 2 miles around the park. Or you can multiply 5 sides (pentagon) times each side of 2/5 mile thus..... 5*2/5 = 10/5 = 2 so this is also 2 miles around the perimeter.

If triangle abc, a=3, b=5 and c=7. Find the measure of angle b

Answers

Answer:

b = 38.22

Step-by-step explanation:

In the given triangle ABC, a = 3, b = 5 and c = 7 is given.

We have to find the measure of angle b.

To get the measure of any angle we will apply cosine rule in the triangle.

b² = a² + c² - 2ac(cosb)

5² = 3² + 7² - 2×3×7×cosb

25 = 9 + 49 - 42×cosb

25 = 58 - 42cosb

-42cosb = 25 - 58 = -33

cosb = (33)/(42)

cosb = 0.7856

b= cos^(-1)(0.7856)

b = 38.22

b = 38.22 is the correct answer.

Answer:

β = arccos((a^2 + c^2 - b^2)/(2·a·c))

β = arccos((3^2 + 7^2 - 5^2)/(2·3·7)) = 38.21°
