Rolando's Labrador retriever had 12 puppies. Eight of her puppies were yellow labs and the rest were black labs. What is the rat

natta225 [31]

Answer:

1:2

Step-by-step explanation:

There are 12 total puppies. To find the number of black puppies, we have to subtract the yellow from the total. So:

12 - 8 = 4

There are 4 black puppies. Now we put the black puppies in ratio to yellow puppies:

4:8

Then simplify (divide both sides by 4):

1:2

Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 m

arsen [322]

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

$OB = 30$ --- Jack

$AB = 78$ -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

$AB^2 = OA^2 + OB^2$

This gives:

$78^2 = OA^2 + 30^2$

$6084 = OA^2 + 900$

Subtract 900 from both sides

$OA^2= 6084 - 900$

$OA^2= 5184$

Take square roots

$OA = \sqrt{5184}$

$OA = 72$

<em>Hence, Jill drove 72 miles</em>
