Answer:

Surface area = 252 inches^2

Step-by-step explanation:

Surface area = 2lw + 2lh + 2wh

2(2*8) + 2(2*11) + 2(8*11)

32 + 44 + 176 = 252

To get better at 12's:
Write down on your paper your 1's facts in column skip 5 and 11 going to 14 (a vertical line - line that goes up and down). To the right of that column, write your two's facts 0 to 8 and repeat again. Then you will have your 12's! Should look as follows

12's:

0    0 = 12 x0
1    2 = 12 x1
2    4 = 12 x2
3    6 = 12 x3
4    8 = 12 x4
6    0 = 12 x5
7    2 = 12 x6
8    4 = 12 x7
9    6 = 12 x8
10  8 = 12 x9
12  0 = 12 x10
13  2 = 12 x 11
14  4 = 12 x 12

Mario invests 1,500 in a savings account that earns 2% interest a year. He also plans to set aside $50 cash a month. A:2100(1.02
Sedbober [7]

Answer:

<em>1500(1.02)^x  +   600x</em> is how much he has in savings at the end of x years where it be in the bank or elsewhere

Step-by-step explanation:

x is in years

Let's just think about the investment of 1500 in an account earning 2% per year.

Before the years even start, you are at 1500 ( present value).

The next year (year 1), it would be 1500*.02+1500=(1500)(1.02).

The next year (year 2), it would be 1500(1.02)(.02)+1500(1.02)=1500(1.02)(1.02).

We keep multiplying factors of (1.02) each time.

So for year x, you would have saved 1500(1.02)^x.

Now we are saving 50 cash per month. Per year this would be 12(50) since there are 12 months in a year.  12(50)=600.  

So the first year you would have 600.

The second year you would have 600(2) or 1200.

The third year you would have 600(3) or 1800.

Let's put this together:

1500(1.02)^x  +   600x
