Answer:

7 people

Step-by-step explanation:

(21 cookies)/(3 cookies/person) = 7 person

_____

If you're really challenged figuring this out, you can count out 21 of some object—such as pennies, scraps of paper, or even cookies—and deal them into piles of 3 each. Then count the piles. Working with actual physical objects can often give you mathematical insight not obtainable any other way.

Each pile subtracts 3 from the original amount. We use the arithmetic operation "division" to simplify repeated subtraction.

Knowing number facts such as 3×7 = 21 is very helpful to solving problems of this nature.

Neko [114]

Answer:

Zero(0)

Step-by-step explanation:

From the given information, we are to determine the probability that both ships are hit given that the pirate shoots first.

There are two scenarios

Since the pirate is to shoot first

If the pirate misses, the Captain's ship is not hit. Therefore there's no chance of both ships getting hit.
If the pirate hits, we are told that if his ship has been hit, Captain Daniel will always miss. Therefore there is also no chance of both ships getting hit.

P(both ships to be hit given that pirate shoots first) =0

sweet-ann [11.9K]

12-pack for 1.69 is a better buy

Solution:

Given that, Mike bought a 12-pack for 1.69 and Mary bought a 24-pack for 3.18

We have to find which is the better buy

First we have to find the unit rate

Unit rate is cost of 1 pack

Mike bought a 12-pack for 1.69

Therefore,

Cost of 12 pack = 1.69

Cost of 1 pack is found by dividing 1.69 by 12

$cost\ of\ 1\ pack = \frac{1.69}{12} = 0.14083$

Thus unit rate of Mike is 0.14083 dollar per pack

Mary bought a 24-pack for 3.18

Cost of 24 pack = 3.18

Cost of 1 pack is found by dividing 3.18 by 24

$cost\ of\ 1\ pack = \frac{3.18}{24} = 0.1325$

Thus unit rate of Mary is 0.1325 dollars

On comparing both the unit rate

$0.14083>0.1325$

Thus unit rate of Mike is larger

Thus, 12-pack for 1.69 is a better buy
