well, what we do is, simply get the area of the containing rectangle, is an 8x10, and then get the area of the circle, with a radius of half of 4.3 or r = 2.15, and then if we subtract the area of the circle from the rectangle's, what's leftover is the shaded part.

\stackrel{\textit{\large Areas}}{\stackrel{rectangle's}{(8\cdot 10)}~~-~~\stackrel{circle's}{[\pi (2.15)^2]}}\implies 80-4.6225\pi ~~\approx~~65.5

Give an example of a real-world cost that depends on an unknown amount of something. Try to create an expression to represent th
lakkis [162]

Answer:

Ok, let's suppose that the unknown amount is the number of books you buy in a library. (let's represent this unknown quantity with the variable X)

We know that each book costs $9.75, and we know that in total cost for the X books is $68.25

Then, how many books do you get?

We know that if one book costs  $9.75, then X books will cost X times $9.75

Then the total cost is:

C(X) = X* $9.75

And we know that the total cost was $68.25

Then to solve this, we need to solve the equation:

X* $9.75 = $68.25

X = $68.25/$9.75 = 7

Find the value of c that makes the trinomial a perfect square. .<br> x² – 24x7c
sergey [27]

Answer:

144

Step-by-step explanation:

The equation to find c is:

(\frac{b}{2} )^{2}

So put -24 into b:

(\frac{-24}{2} )^{2}

Which simplifies to:

144

So if you want to test this:

x^2 - 24x + 144

is

(x-12)^2
