To find this we will first find out how much interest they accrued within 20 years. We'll do that by multiplying all the given factors:

2000 x 0.049 x 20 = 1960
This shows they have made $1,960 in accrued interest. We'll add this sum by the original deposit they made of $2,000.

2000 + 1960 = 3960

In the end of 20 years of accrued interest, the person will have a total of $3,960 in their account.

pickupchik [31]

The calories in a cup of low fat milk is 102 calories and the  calories in a cup of milk in skim 86 calories .

<h3>What are the two simultaneous equations that can be sued to represent this question?</h3>

2/3l + 1/2s = 111

4l + 3s = 666 equation 1

l + s = 188 equation 2

Where:

l = calories in the low fat milk

s = calories in the skim milk

<h3>What is the calories in the skim milk?</h3>

Multiply equation 2 by 4

4l + 4s = 752 equation 3

Subtract equation 1 from 3

s = 86

<h3>What is the calories in the low fat milk?</h3>

Substitute for s in equation 2

l + 86 = 188

l = 188 - 86

l = 102

A pet owner has 5 cats. Each cat has 2 ears and 4 paws. Complete the double number line to show the numbers of ears and paws for
aleksandrvk [35]

Answer:

If there are 3 cats in the room, what is the ratio of ears to paws?  1 : 2

If there are 4 cats in the room, what is the ratio of paws to ears?  2 : 1

If all 5 cats are in the room, how many more paws are there than ears? the number of paws is twice as more than the number of ears, we have 10 more paws than ears.

Step-by-step explanation:

You can see the double number line for this situation in the attached photo.

So as we can see in the double number line diagram, if there are 3 cats in the room we would have an ears to paws ratio of 6 : 12 , which simplified would be 1 : 2, meaning that for every ear there are 2 paws.

For the next question, if there are 4 cats in the room, the paws to ears ratio would be 16 : 8, simplified to 2 : 1, meaning that for every 2 paws there is 1 ear.

And for the last question, if all 5 cats are in the room, we have that the paws to ears ratio is 20 : 10, simplified again to 2 : 1, meaning the number of paws is twice as more than the number of ears, so in this case we have 10 more paws than ears.
