12+12 is 24, 24+24 is 48, and 48+4 is 52. Hope this helps!

variable- p=pie

12p≥500

The answer would be at least 42.

When you divide 500/12, you get 41.66666667. Since you can't sell that amount of cake, you have to round it up. You round it up instead of down because if you round down, then you won't have that amount anymore, and you will have less. Rounding it up will insure that you will get the right amount of money, even though you will have a few cents left over.

Hope this helps!<3

Match each function with the corresponding restrictions to its domain when p(x)=2x and q(x) = 2^x.

ASHA 777 [7]

Recall that the domain of a function is the set of all x values of the function for which the function is defined.

Given that
$p(x)=2x$ and $q(x)=2^x$

Given that
$r(x)= \frac{q(x)}{p(x)} = \frac{2^x}{2x}$
For the function to be undefined, the denominator should be zero
i.e. 2x = 0 which means that x = 0
Thus, the domain of the function is all real values of x except 0.

Therefore, the restriction is x ≠ 0.

Given that
$r(x)= \frac{1}{p(x)-q(x)} = \frac{1}{2x-2^x}$
For the function to be undefined, the denominator should be zero
i.e.
$2x-2^x=0 \\ 2^x=2x$
For x = 2,
$2^2 = 2(2)=4$
Also, for x = 1
$2^1 = 2(1)=2$
Thus, the domain of the function is all real values of x except 1 and 2.

Therefore, the restriction is x ≠ 1, 2.

Given that
$r(x)= \frac{1}{p(x)+16q(x)}=\frac{1}{2x+16(2^x)}$
For the function to be undefined, the denominator should be zero
i.e.
$2x+16(2^x)=0 \\ 2x+2^4(2^x)=0 \\ 2x+2^{4+x}=0$
For x = -2,
$2(-2)+2^{4-2}=-4+2^2=-4+4=0$ .
Thus, the domain of the function is all real values of x except -2.

Therefore, the restriction is x ≠ -2.

Given that
$r(x)=p(x)\circ q(x)=p(q(x))=2(2^x)$
There is no value of x, for which the function is undefined.
Thus, the domain of the function is all real values of x.

Therefore, there is no restrictions to the domain of the function.

Given that
$r(x)= \frac{q(x)}{p(x)+2}=\frac{2^x}{2x+2}$
For the function to be undefined, the denominator should be zero
i.e.
$2x+2=0 \\ 2x=-2 \\ x = -1$
Thus, the domain of the function is all real values of x except -1.

Therefore, the restriction is x ≠ -1.

Ms.ford’s kitchen is in the shape

gtnhenbr [62]

Ms. Ford's kitchen is in the shape of a rectangle with a width of 12.25 feet. She is buying a wallpaper border to go on all of her kitchen walls. She wants to buy 5 extra feet of the border to be sure she has enough. She buys 62.5 feet of the border. What is the length of ms. Ford's kitchen?

is that what u meant???

if sooo

The length of Ms. Ford's kitchen is 57.5 feet.

HOW-

The kitchen is a rectangle and she wants to buy 5 feet of wallpaper. And she buys 62.5 feet of wallpaper border. Just subtract 62.5 and 5 and you get 57.5 feet.
