Answer:
Defining the straight number of integers, we have to live in the year 2020 and this Greek historian was born in the year - 484.
Step-by-step explanation:
When using whole numbers, we denote positive numbers as the number of numbers after 0, and negative numbers the number of numbers before zero.
So if we consider the birth of Christ to be the year 0, then all years before Christ will be negative and all years after Christ will be positive.
So we have to live in the year 2020 and this Greek historian was born in the year - 484.
Answer:
1.6 * 10^{-8}
Step-by-step explanation:
Given the following data;
Time = 0.000000016 nanoseconds
To express in standard scientific notation;
Scientific notation is a standard way of expressing very large numbers in powers of 10.
0.000000016 nanoseconds = 1.6 * 10^{-8} nanoseconds.
Note: count the number of zeros (0s) before 1 and write it to the power of 10.
Ok, to solve this, once again you need to fold this map back up into a 3d shape ( in your head).
What you should see is that the little overhanging sides that had no measurement, now have a measurement. They measure up to be the same as the 3m. sides.
so to find the area of all the rectangles, you need to multiply the base times height. (b)h
I will start from the left of your pic. and work my way to the right...not including the little overhanging ones.
The first one should measure out to be 3(15) =45
The second to be 6(15) =90
The third to be 3(15) =45
The fourth to be 6(15) =90 :)
So you have these, but now you need to get the little over hangers I call them...lol.
The width is 6, same as the rectangle they are attached to. And the picture in your mind should tell you that the height is 3, the same as the width of the skinny rectangles that they attach to in your mind.
Soooo now they measure out to be 3(6) =18. and you just multiply this by two because they are the same area, right? So that would be 36.
ok. Now add all of the areas of the surfaces 45+90+45+90+36 to get a total surface area of.... *drummel please* 306m^2
this means 306m. to the power of 2 if you didn't know.
well, I hope you understand better and I hope I helped! ;)
Let’s do 3x - 8 ≤ 23 first.
You need to rearrange this so that x is on its own.
+8 to both sides
3x ≤ 31
/3 on both sides
x ≤ 31/3
Then the second, -4x + 26 ≥ 6
-26 from both sides
-4x ≥ -20
/-4 on both sides
x ≥ 5
So x is greater than or equal to 5, which can also be written as 5 ≤ x
And for the first one, x is less than or equal to 31/3, which can still be written as x ≤ 31/3, so your final answer is:
5 ≤ x ≤ 31/3
