Answer:

  s ≤ 4(0.20×80)

Step-by-step explanation:

The maximum Jason spends each week is 0.20 × $80. Then the amount (s) he spends in 4 weeks will be less than or equal to 4 times this product.

  s ≤ 4(0.20×80)

I could go through and answer it all and give you the answer but i think this will be better. Scientific Notation is just a way to sum up a long number so you don't have to write out a bunch of zeros. Without talking about "significant figures" you just put a decimal point after the first actual number, add a "x 10" then count the zeros and write the number as a superscript to the 10. any number like this 0.000.... (<em>smaller than 1</em>) has a negative superscript. any number like 10000... (<em>larger than 1</em>) has a positive superscript.

Example:
6,200,000 = 6.2 x 10^6
&
0.0000062 = 6.2 x 10^-6

Here are some general rules now that you know what you are trying to do:

1. Scientific Notation ONLY ever has ONE number in front of the decimal, like this: 6.02 x 10^23.
NOT LIKE THIS: 60.2 x10^23 or 61.2 x 10^23
and NEVER a zero like this: 0.70 x 10^23.

2. it is ONLY ever a multiplication symbol, 6.02 "x" 10^23, NEVER divide, + or -.

3. for the examples on this paper, do NOT include zero's on the end like this 7.20 x 10^23. Only the actual numbers, and, <em>zeros that are</em> <em>between numbers</em> like this 6.0201 x 10^23. The zero's on the end get summed up and are noted in the ^23 part. (<em>This part is called a superscript, in case you didn't know that</em>)

4. In the last section they are just showing you some incorrect stuff to trick you up. Just put the decimal in the correct place and adjust the ^23 superscript bit.

shawn drew a rectangle that was 2 units wide and 6 units long..draw a different rectangle that has the same perimeter but a diff
defon
2(2)+2(6)= 16, so the perimeter must be 16. Let’s make one of the side lengths l = 3, so 2(3)+2(w)= 16, or w = 5. You can check by multiplying the dimensions that the areas are different.

The hypotenuse can be solved by this formula. X^2 = 6^2 +6^2

X^2=64
Usually you cut it down to 8 but it wants the squared form so 64.

Given the ordered pairs (5,3), (-4, 2) and (-2,-6)
Furkat [3]
Answer: ( -2, 4 )

Reason:
The x value is horizontal. Thus anything that says left or right is talking about the x value.
The x value is listed first on the point
(x, y)
When the x value goes left it is negative
When it goes right it is positive

The y value is vertical
It is listed last on the point (x , y)
When it goes up it is positive
When it goes down it is negative

Hope this helps
