Find the sum of 301+73+27, mentally, using the Associative Property of addition. Show how you can use the property to group two of the addends. Explain how you found the sum.

Answers

Answer 1

Answer: The answer is 401, because you can put parenthesis between 73 and 27. The equation would now be 301+(73+27). You do the expression inside the parentheses first. Now it will be 301+(100) which is the same as 301+100. You know 301 plus 100, which is 401. There's your answer. I hope this helped.

Text- Many egg producers keep chickens in small cages that do not allow the chickens to move. Some people believe that this is unhealthy, so they buy eggs from chickens that are not caged 24-hours a day. These are sometimes called "free-range" chickens. The United States Department of Agriculture (USDA) allows chickens to be called free-range as long as the chickens spend some of their time outside. The European Union (EU), however, has several additional restrictions. One of these is that the farmers must provide enough outside area so that if all the chickens were outside, the density of chickens would be no more than 0.25 chickens/sq meter. (Wikipedia, 2014).question 1- How many square meters does the EU require for one chicken? question2-A farmer in the United States wants to meet the EU guidelines. She measures her area in square yards (1 sq meter =1.196 sq yards). How many square yards does she need for 1,100 chickens?

brainly.com/question/8182874

Step-by-step explanation:

Answer:

Area: 5π/2 in²

Perimeter: (3π+2) in

step-by-step explanation:

Area =

larger semicircle + small semicircle

= ½(pi × r1²) + ½(pi × r2²)

r1 = 2 in

r2 = 2/2 = 1 in

Area:

½(pi × 2²) + ½(pi × 1²)

= 2pi + ½pi

= 5pi/2 in²

Perimeter:

½(2pi × r1) + ½(2pi × r2) + r1

½(2pi × 2) + ½(2pi × 1) + 2

2pi + pi + 2

3pi + 2
