Mr. Simpson feeds his dog

Liono4ka [1.6K]

Answer:

The total of 4 cups lasts 8 days to Mr. Simpson.

Step-by-step explanation:

The 1/2 cups of food lasts 1 day

⇒ 1 cup of food lasts = $(\frac{1}{\frac{1}{2} })$ = 2 days.

Now, Mr. Simpson has 4 cups.

So, 4 cups last him = 4 x 2 days = 8 days

Hence, a total of 4 cups lasts 8 days to Mr. Simpson.

Use the Pythagorean theorem. We have legs with lengths of 15 and 20 miles, now let's solve for the hypotenuse.

$a=15$
$b=20$
$c=?$

$a^2+b^2=c^2$
$15^2+20^2=c^2$
$c^2=400+225=625$
$c=25$

Your answer is 25 miles. Hope this helps! :)
