Landon usually eats two slices of pizza from a 12 inch pizza cut into 6 slices. I make homemade pizza on a rectangular cookie sh
LUCKY_DIMON [66]

Answer:

He will eat 0.233 of one slice

Step-by-step explanation:

If Landon eats only two slices of pizza from a 12 inch pizza cut into 6

It means each slice has 2 inch pizza and Landon eats 2 of these

So Landon eats 2*2 = 4 inch pizza

So a rectangular pizza of 10 by 15

= 10*15

= 150 inch pizza

Cut into 8 slices

= 150/8

.= 18.75 inch per slice

4/18.75 = 0.233

He will eat 0.233 of one slice

Given the table of values below, which of the following ordered pairs are found on the graph of the inverse function? A. (-2, -1
Ainat [17]

Given:

The of values of a function.

To find:

The ordered pairs that are found on the graph of the inverse function.

Solution:

If a function is defined as

f(x)=\{(x,y):x\in R,y\in R\}

Then its inverse function is defined as

f^{-1}(x)=\{(y,x):x\in R,y\in R\}

From the given table it is clear that, the ordered pairs of the function f(x) are :

\{(-2,-14),(-1,10),(0,6),(1,2),(2,-2)\}

So, ordered pairs of the inverse function are :

\{(-14,-2),(10,-1),(6,0),(2,1),(-2,2)\}

Therefore, the correct option is B.

Points M and N are both on ZB with M between Z and N. ZM = 10
maxonik [38]

Answer:

Your answer is 40%

Step-by-step explanation:

It is 20 units between Z and B.

We add 2 more points, and one of them is at the the halfway point of the entire line.(M)

One of them is only 2 units away from B.(N)

That means our line is halved, so from 20/20 possible places a point could go and land in the right area is now 10/20.

Minus 2 from that; to take into count of the N to B, and you have 8/20

8/20 is just 40%
