Answer:

Step-by-step explanation:

To figure out whether a triangle is a right triangle using only the side lengths, you can use the Pythagorean theorem:

a^2 + b^2 = c^2

1.5^2 + 2^2 = 3^2

2.25 + 4 = 9

Since this equation isn't true, these numbers cannot be the side lengths of a right triangle.

vovikov84 [41]

Given :

Amount of candy Jordan have , $A=\dfrac{3}{8}\ pounds$ .

Amount left after giving some to brother , $a=\dfrac{1}{10}\ pounds$ .

To Find :

Solution :

Let , amount he gave to his brother is , b .

So ,

$\text{Amount left = Total amount -Amount he give to his brother}\\\\a=A-b\\\\b=A-a\\\\b=\dfrac{3}{8}-\dfrac{1}{10}\\\\b=\dfrac{(3\times 10)-8}{80}\\\\b=\dfrac{22}{80}\\\\b=\dfrac{11}{40}$

So , amount he give to his brother is $\dfrac{11}{40}$ .

Hence , this is the required solution .
