Kathy spent 5/8 of her money on books and another 1/6 of her money on stationeries.what fraction of kathy’s money was left?

5/24

Step-by-step explanation: 5/8 =30/48 + the 8/48 she spent = 38/48 48/48 - 38/48= 10/48. that simplifies to 5/24

we know that

the volume of the oblique pyramid with a square base is equal to

V=\frac{1}{3}BhV=

3

1

Bh

where

B is the area of the base

h is the height of the pyramid

In this problem

The area of the base is

B=EF^{2}\ units^{2}B=EF

units

h=AB\ unitsh=AB units

The two formulas to calculate h are

Applying the Pythagoras Theorem

h^{2}=AC^{2}-CB^{2}h

2

=AC

−CB

2

> h=\sqrt{AC^{2}-CB^{2}}h=

AC

−CB

h^{2}=AD^{2}-DB^{2}h

2

=AD

−DB

> h=\sqrt{AD^{2}-DB^{2}}h=

AD

−DB

therefore

the answer is

AB and EF

AC, CB and EF

AD, DB and EF
