What is 2.1 times 3.2 find the missing partial products HELP.​
vredina [299]

Given:

The area model for 2.1\times 3.2.

To find:

The value of 2.1\times 3.2 and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

2\times 3=6

2\times 0.2=0.4

0.1\times 3=0.3

0.1\times 0.2=0.02

The complete area model is shown below.

After adding all areas of the area model, we get

6+0.4+0.3+0.02=6.72

Therefore, the value of 2.1\times 3.2 is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

At noon, a barista notices she has $20 in her tip jar. If she makes an average of $0.50 from each customer, how much will she ha
RSB [31]

Answer:

She has $20 + $0.50n in her tip jar.

Step-by-step explanation:

Amount in tip jar at noon = $20

Average amount made from each customer = $0.50

Number of additional customers served after noon = n

Therefore, we have:

Additional amount made after noon = Average amount made from each customer * Number of additional customers served after noon = $0.50 * n = $0.50n

Amount in tip jar = Amount in tip jar at noon + Additional amount made after noon = $20 + $0.50n

Therefore, she has $20 + $0.50n in her tip jar.
