What is the approximate area of the circle that fits perfectly inside of the square? Use Pi = 3.14 and round to the nearest tent
Pani-rosa [81]

Answer:

19.625\text{ cm}^2

Step-by-step explanation:

GIVEN: A square with base 5\text{ cm}, a circle that perfectly fits inside square.

TO FIND: Approximate area of circle.

SOLUTION:

Consider the figure attached.

let the radius of circle be x\text{ cm}

radius of circle =\frac{\text{length of base of square}}{2}

                     x=\frac{5}{2}\text{ cm}

                     x=2.5\text{ cm}

Area of circle =\pi(radius)^2

                      =3.14\times(2.5)^2

                      =19.625\text{ cm}^2

Hence the area of circle that perfectly fits inside the square is 19.625\text{ cm}^2

Let f(x) = 3x + 2 and g(x) = x - 3. Find g(x) - f(x) and state its domain.
Bad White [126]
We have that

<span>f(x) = 3x + 2
</span><span>g(x) = x - 3

[</span>g(x) - f(x)]=(x-3)-(3x+2)--------> (x-3-3x-2)-----> -2x-5

the domain is all real numbers

the answer is
<span>–2x – 5; all real numbers</span>

Car lot one has a car to truck ratio of 3:4. Car lot two has a car to truck ratio of 2:3. Which car lot has more cars when both
Pani-rosa [81]

Answer:

this means that lot 1 would have more cars. there were 3 cars in lot 1 and 2 in lot 2

Step-by-step explanation:

lot 1-          lot 2-

3:4             2:3

if both have 12 trucks, you need to multiply the number of cars with the number you used to make the trucks 12

3:4 would turn into 9:12

2:3 would be 8:12

this means that lot 1 would have more cars. there were 3 cars in lot 1 and 2 in lot 2
