Esther starts at one corner of a square field and walks 90 feet along one side to another corner of the field. She turns 90° and walks 70 feet, and then walks straight back to where she started. What is the area of the part of the field she walked around?a. 3150 ft²
b. 4900 ft²
c. 6300 ft²
d. 8100 ft²

Answers

Answer 1

Answer: Since it is a square field and she walked from one corner to another, each side of the square filed is 90 feet.
Since she walked 70 feet and then straight back to where she started, she has formed a triangle, the legs are 90 and 70 and the hypotenuse (the distance back to the start) is not needed to solve this problem.
So we have a triangle whose length is 90 and whose height is 70
A = $(1)/(2)$ bh or in this case $(1)/(2)$ (90) x (70) or 1/2 of 6300. Answer a. 3150 ft² is half of 6300 and is the correct answer

A camp ground consists of 12 square campsites arranged in a line along a beach. The distance from the edge of a campsite to the water at the end of the beach is 5 yards. The area of the campground, including the beach, is 1,248 square yards. What is the width of one campsite/

Answers

x=side length of a campsite
12x(5+x)=1248 because each campsite has a length of x and there are 12 and from the top of the camp to the water is the 5 yds + a side length and LW=1248
60x+12x^2=1248
12x^2+60x-1248=0
x^2+5-14=0
(x+7)(x-2)=0
x+7=0 or x-2=0
x=-7 or x=2
x=2 because width can't be negative
the width of one campsite is 2 yds

Step-by-step explanation:

Answer:

Yes your answer is correct

Step-by-step explanation:

First of all you multiply 3x with 2x which equals 6x power 2 because we sum the power. Then we multiply 6x power 2 with x power 4 which equals 6x power 6 because X is 1X so the answer is 6X power 6

If it takes 3 days for 10 workers to finish building one house, how many days will it take 15 workers to finish four houses?

Answers

-- It takes 10 workers 3 days to build 1 house.
so
-- It takes 10 workers 1 day to build 1/3 of a house.
so
-- It takes 1 worker 1 day to build 1/30 of a house.

You got 15 workers and you need 4 houses ?

Well, as we just calculated . . .

-- It takes 1 worker 1 day to build 1/30 of a house.
so
-- It takes 15 workers 1 day to build 15/30 = 1/2 of a house.
so
-- It takes 15 workers 2 days to build 1 whole house.
so
-- It takes 15 workers 8 days to build 4 houses.
