Simplify just means put together everything into one big thing. In this case that is just adding. To add a fraction and a decimal we have to convert the fraction into a decimal as well. The decimal form of 1/4 is 0.25, and as such, 3/4 is .75. This means we have -0.75+1.5. Adding a positive to a negative is the same thing as simply subtracting the first number from the second, or 1.5-0.75. This is .75. The answer is C.

a circular dog pen has a circumference of 78.5 feet. approximate by 3.14 and estimate how many hunting dogs could be safely kept
olasank [31]

Answer:

  8

Step-by-step explanation:

To solve this problem, we need to find the area of the pen, then divide that by the area required by each dog.

__

The relationship between circumference and radius is ...

  C = 2πr

Solving for r gives ...

  r = C/(2π)

The relationship between radius and area of a circle is ...

  A = πr²

Substituting for r from above gives ...

  A = π(C/(2π))² = C²/(4π)

Filling in the given numbers, we find the area of the pen to be ...

  A = (78.5 ft)²/(4·3.14) = 490.625 ft²

__

Dividing the pen area by the area per dog gives the number of dogs the pen can hold:

  (490.625 ft²)/(60 ft²/dog) ≈ 8.18 dogs

The pen can safely keep 8 dogs.
