jdoe0001 · Answer

and the hypotenuse is the shortest distance between those two points

anonymous · Answer

so the pathagreom theroum is A+b=c so 4+6=c so 4+6=10? so is 10 the answer

anonymous · Answer

@jdoe0001

jdoe0001 · Answer

well... the pythagorean theorem is $\large c^2=a^2+b^2\iff c=\sqrt{a^2+b^2}$

anonymous · Answer

wait so Is the answer 52 ?

jdoe0001 · Answer

52?   how did you get 52?

anonymous · Answer

uhh well.. idk

jdoe0001 · Answer

$\bf c^2=a^2+b^2\iff c=\sqrt{a^2+b^2}\qquad thus
\ \quad \
c=\sqrt{6^2+4^2}\implies c=\sqrt{36+16}\implies c=\sqrt{52}\implies c=?$

anonymous · Answer

so I kind of did it right ok ummm
7.21 
but it needs to be in a fraction and I don't know how to do that

jdoe0001 · Answer

7.21 has two zeros
thus $\bf 7.\underline{21}\iff \cfrac{721}{1\underline{00}}$

two zeros at the denominator

anonymous · Answer

so its 721/100  is the answer?

jdoe0001 · Answer

if you're using 7.21 as a fraction, yes

anonymous · Answer

well what is that simplified

anonymous · Answer

@jdoe0001 how do I simplify 721/100

anonymous · Answer

Wait I still don't know the last answer?

directrix · Answer

Do you have answer options?  Square root of 52 is correct.

anonymous · Answer

I don't have options

@ShyKitty

directrix · Answer

How do you know that you are supposed to leave the answer as a fraction.

Maybe, a decimal answer? Look at the instructions to see what format the answer is to be entered.

anonymous · Answer

it says : Directions: Show all your work. Round your answer to the nearest tenth. Answer the question in a complete sentence with the correct units of measure.

directrix · Answer

>>>Round your answer to the nearest tenth. 

What is 7.211102 written to the nearest tenth.

 7.2   1   1102    

1 is not 5 or greater so 7.2 miles.

Do you agree?

anonymous · Answer

yea that sounds right
so she walk 7.2 miles ok

directrix · Answer

When you wrote this >   but it needs to be in a fraction   
things became confused.

A decimal is what you meant to write. 

No worries.

directrix · Answer

Alrighty, then.

anonymous · Answer
