Answer:
$30
Step-by-step explanation:
If the CD paid back 3% interest of the money you put in, all you have to find is what 3% of $1000 is.
3% = 0.03.
0.03 x 1000 is $30.
You earned $30 in interest.
Answer:
The answer is 30
Step-by-step explanation:
To get a.b
For a = <wa, za> and b = <wb, zb>, the dot product represents multiplication sign.
We say,
a•b = (wa)(wb) + (za)(zb)
The next step is to substitute the given information into the above equation we generated.
Then we say,
a•b = 5•4 + 2•5
a.b = 20 + 10
a•b = 30
The answer is 30
Answer: 
Step-by-step explanation:
You need to remember the multiplication of signs:

And the the Distributive property. This states that:
In this case, given the following expression:

In order to to create an equivalent expression, the first step is to apply the Distributive property. Then:

You can identify that the like terms are:
and 
So, you can combine these like terms. This means that you must add them. Since both terms have equal denominator, you need to rewrite the denominator and just add the numerators.
Then, you get:

a. (2x + 6) - 4 represents how to find the area of the table cloth. (to be honest, I'm not sure why you have to subtract the lace, or what I'm assuming is the lace...)
b. 2x + 6 represents how to find the area of the table cloth.
c. 2x represents the x length getting multiplied by 2, since there are 2 sides.
I hope this helps just a little bit though. I'm sorry I could get part a very well.
1.
43.85 + 2(2.70) + 2(-1.10) - 4.45
43.85 + 5.40 - 2.20 - 4.45
$42.60
2.
1.40(15) = 21
$21
3.
15(3) + 3(9) + 7
45 + 27 + 7 = 79
$79
4.
15 - 45 / 9
15 - 5
10
5.
0.75(79.99)
$59.9925 (can be rounded to just $59.99)
