1/9+29/8 what is the answer? ps: i need to show my work

miskamm [114]

1/9 =   1.11
29/8 = 3.63
   -------
   3.73 = 269/72

or....
1/9 >>> 8/72    (72 is the common denominator) (Multiply the N and D by 8)
29/8 >>> 261/72    (72 is the common denominator) (Multiply the N and D by 9)
   -------------
   269/72

A restaurant serves custom-made omelets, where guests select meat, cheese, and vegetables to be added to their omelet. There are

FrozenT [24]

Answer:

15 possible combinations

Step-by-step explanation:

Given

$Vegetables = 6$

$Selection = 2$

Required

Determine the possible number of combinations

The question emphasizes on "selection" which means "combination".

So; To answer this question, we apply the following combination formula:

$^nC_r = \frac{n!}{(n-r)r!}$

In this case:

$n = 6$

$r = 2$

The formula becomes:

$^6C_2 = \frac{6!}{(6-2)!2!}$

$^6C_2 = \frac{6!}{4!2!}$

$^6C_2 = \frac{6*5*4!}{4!2*1}$

$^6C_2 = \frac{6*5}{2}$

$^6C_2 = \frac{30}{2}$

$^6C_2 = 15$

<em>Hence, there are 15 possible combinations</em>

Solve for the width in the formula for the area of a rectangle.

madam [21]

A = L * W
A / L = W <==

when A = 42 and W = 16.8
A / L = W
42/16.8 = W
2.5 = W <=== width = 2.5 inches

Let f(x) = x2 - 81. Find f-1(x).

dusya [7]

This is equivalent to finding a function g in which $g(x^2-81)=x$ .

We simply reverse the actions of the initial function by adding 81 back and taking the square root. Therefore, $f^{-1}(x)=\sqrt{x+81}$ .
