Can someone put this in order

Answers

So in order to figure this out we need to know the formula for simple interest
In this case it is. 
I = p r t  (they are all multiplied by each other) 

p = "principle" or the starting amount of money
r = the rate or percentage
t = time (in years)
So lets figure it out in the order they give it to us. Then Put them least to greatest. 

So the first one is 
Investment at $3,000 at 16% simple interest for 2 years. 
We multiply them all together to get our interest. 
lets do the math:) 
16% = 0.16 
$3,000 x 0.16 x 2 = $960

Now lets do the second one.
Investment of $3,000 at 5% simple interest for 20 years. 
Lets multiply them all together. 
5% = 0.05 
$3,000 x 0.05 x 20 = $3,000

Now for our third one. 
Investment of $1,000 at 16% simple interest for 20 years 
Lets multiply them together. 
16% = 0.16 
$1,000 x 0.16 x 20 = $3,200

Now here is our answer ↓↓↓

Now to put these in order from least to greatest. 
1st.) Investment at $3,000 at 16% simple interest for 2 years. = $960
2nd.) 
Investment of $3,000 at 5% simple interest for 20 years.= $3,000
3rd.)Investment of $1,000 at 16% simple interest for 20 years.= $3,200

What mixed number represents 2.85

Answers

First, take out the whole number portion, and solve the decimal part, which is 0.85. 0.85 = 85/100. So, the mixed number would be 2 85/100. However, most teachers want you to simplify your mixed numbers, so divide both numbers by a factor that you think is common. 5 is a common factor, so 85/5 = 17. 100/5 = 20. So, the answer is simplified to 2 17/20.
Hope that helped.

What is the ratio of ounces to pounds in the weight of an object

Answers

Answer:

1 : 0.0625

Step-by-step explanation:

We are asked to find the ratio of ounces to pounds in the weight of an object.

We know that 1 pound equals 16.

Ratio of pound to ounce= 1 : 16

To find the ratio of ounces to pounds, we will divide 1 by 16.

(1)/(16)=0.0625

Ratio of ounce to pound= 1 : 0.0625

Therefore, our required ratio is 1 : 0.0625.

1 Pound = 16 Ounces
1 Ounce = 0.0625 Pounds
