Vikki [24]

Answer:

21.3%

Step-by-step explanation:

Given that:

Money spent by Jodie for buying English reading books = 25% lesser than that of Claudia

and

Money spent by Gianna is 9% lesser than that of Claudia.

To find:

By what percent, Gianna spent more than Jodie ?

Solution:

Let the money spent by Claudia on her English books = 100

Now, as per question statement:

Money spent by Jodie = 100 - $\frac{9}{100}\times 100$ = 75

Money spent by Gianna = 100 - $\frac{25}{100}\times 100$ = 91

Now, to find the answer:

$\dfrac{\text{Difference between money spent by Gianna and Jodie}}{\text{Money spent by Jodie}}\times 100$

$\Rightarrow \dfrac{91-75}{75}\times 100\\\Rightarrow \dfrac{16}{75}\times 100\\\Rightarrow \bold{21.3\%}$

Therefore, Gianna spent <em>21.3% </em>more than the amount that was spent by Jodie.

How do I solve for X?

lidiya [134]

We use the theory of Pythagoras because the triangle is right.

$AB {}^{2} = AC {}^{2} + BC {}^{2}$
since AB = AC = x
$8 {}^{2} = x {}^{2} + x {}^{2}$
$64 = 2x {}^{2}$
$32 = x {}^{2}$
$x = \sqrt{32}$
$x = \sqrt{16 } \times \sqrt{2}$
$x = 4 \sqrt{2}$
