You need 864.52 sq. in. of blue tile.

We need to find the area of the large circle (including blue and yellow) and the area of the yellow circle.

We have the circumference of the blue circle, 113.097.
C = πd
113.097 = 3.14d

Divide both sides by 3.14:
113.097/3.14 = 3.14d/3.14
36.018 = d

The diameter is twice as much as the radius, so r = 36.018/2 = 18.009.

The area of a circle is given by the formula
A = πr²
A = 3.14(18.009)² = 1018.38 sq. in.

The area of the small yellow circle is given by
A = 3.14(7²) = 3.14(49) = 153.86

Subtracting these two, we have
1018.38 - 153.86 = 864.52 sq. in.

(a) Complete the table of values for y = 6 - 4x. Please help ❤️

Answer:

$\boxed{\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & 10& 6& 2&(-2)&-6 \\\cline{1-6}\end{tabular}}$

Step-by-step explanation:

Given equation to us is :-

$\implies y = 6 - 4x$

So , here we can put different values of x in order to get different values of y .

Initial table given to us is ,

$\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & & & 2&&-6 \\\cline{1-6}\end{tabular}$

Put x = (-1) :-

$\implies y = 6 - 4x \\\\\implies y = 6 -4(-1) \\\\\implies y = 6 + 4 \\\\\red{\bf\implies y = 10}$

Put x = 0 :-

$\implies y = 6 - 4x \\\\\implies y = 6-4(0) \\\\\implies y = 6 - 0 \\\\\pink{\bf\implies y = 6 }$

Put x = 2 :-

$\implies y = 6-4x \\\\\implies y = 6 - 4(2) \\\\\implies y = 6 - 8 \\\\\blue{\bf\implies y = (-2)}$

Hence the final table would be :- 

$\begin{tabular}{|c|c|c|c|c|c|}\cline{1-6} \bf x & -1 & 0&1&2&3\\\cline{1-6} \bf y & 10& 6& 2&(-2)&-6 \\\cline{1-6}\end{tabular}$

When you go to the store, does tax increase or decrease the cost of your items?
