$250 at 6% for 4 years find the interest
MariettaO [177]

Answer:

I=60

Step-by-step explanation:

So

P=$250

R=6%

T=4

So to get the answer we would need to multiply everything to get the interest so the answer would be 60 because 250 times 6% equals to 15 then we would multiply 15 by 4 and then get out answer of $60 interest.

Describe a real world problem you can solve with the help of a yard stick
Mashutka [201]
Fiona has a patch of backyard behind her house in a meadow (she lives in the country). Seeing as the soup kitchen miles down the road is having some issues with the lack of vegetables to cook food for the poor, she decides to make the small rectangular patch of fertile soil into her own veggie garden.
Fiona wants to measure the perimeter of her patch using a few rulers, but she only has yard sticks. Without any rulers to measure with, Fiona decides to use the yard sticks anyway, and begins to measure the plot of land.
The length of the patch is 59 yard sticks long. The width is 24 yard sticks long. Using the concept of <em>1 yard = 3 feet</em>, find out how many feet are in the garden's perimeter. Write your answer down in words and another in a picture.


I hope you like this problem, and that you didn't rage over my long period of time typing this! Have a good night! :P
