Answer:

yes, 28/33

Step-by-step explanation:

For any pair of real numbers, there are an infinite number of numbers between them.

These two numbers can be written with the common denominator 66 as ...

10/11 = 60/66

5/6 = 55/66

Numbers between these that have that same denominator are ...

{56/66, 57/66, 58/66, 59/66}

Of course, there is no requirement that the number be rational, or that it have this denominator. Other numbers between your pair include ...

{56/67, 59/65, √(25/33), π/3.6}

A jacket is on sale for 40% off .The sale price is $90.00.What is the original amount of the jacket

34kurt

Set up a proportion
90/x = 60/100
60x = 9000
x = 150

if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%

hope this helps!

Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest ten

Leona [35]

Answer:

$t \approx 50.4\,min$

Step-by-step explanation:

The time constant of the element X is:

$\tau = \frac{13\,min}{\ln 2}$

$\tau = 18.755\,min$

The decay function has the following form:

$\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }$

$t = -\tau \cdot \ln \frac{m}{m_{o}}$

$t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)$

$t \approx 50.4\,min$

Here's the question sorry

Lunna [17]

L = total number of slices for Luke

K = total number of slices for Kira

A = total number of slices for Ali

$\stackrel{\textit{two thirds of all slices}}{\cfrac{2}{3}L}=4\implies 2L=12\implies L=\cfrac{12}{2}\implies L=6 \\\\\\ \stackrel{\textit{two thirds of all slices}}{\cfrac{2}{3}K}=6\implies 2K=18\implies K=\cfrac{18}{2}\implies K=9 \\\\\\ \stackrel{\textit{two thirds of all slices}}{\cfrac{2}{3}A}=8\implies 2A=24\implies A=\cfrac{24}{2}\implies A=12$
