Answer:
9.5 * 10^-2 mm
Step-by-step explanation:
To find the total thickness, we proceed to add the two thickness that we have
Mathematically, this will be;
0.025 mm + 7 * 10^-2 mm
7 * 10^-2 mm = 0.07
So we have;
0.025 mm + 0.07 mm = 0.095
In scientific notation, this is 9.5 * 10^-2 mm

Answer: 17</h3>
=========================================================
Work Shown:
a1 = 3 = first term
d = 2 = common difference (since we add 2 to each term to get the next one)
Let's compute the nth term.
an = a1 + (n-1)*d
an = 3 + (n-1)*2
an = 3 + 2n-2
an = 2n+1
-----------------------
To check things so far, we can plug in something like n = 2
an = 2n+1
a2 = 2*2+1
a2 = 5
Showing that the 2nd term is 5, which matches with the sequence given to us
Let's check n = 3
an = 2n+1
a3 = 2*3+1
a3 = 7
That matches as well. I'll let you check the others.
-----------------------
Plug in n = 8 to find the 8th term
an = 2n+1
a8 = 2*8+1
a8 = 17
The eighth term is 17, which is the final answer.
-----------------------
You could extend out the given sequence by adding 2 each time until you reach the 8th term
3,5,7,9,11,13,15,17
Though this method is slow if you need to find say the 38th term
Answer:
x = 22, and im rlly sry, i dont know how to solve for y...im sry...
Step-by-step explanation:
180 - 55 = 125 degrees
so
6x - 7 = 125
<u> +7 +7</u>
6x = 132
divide by 6
<u>x = 22</u>
360/18= 20
so the answer is 20 degrees
There is one negative number. Do you think the answer is a negative, out of the answer choices they gave you? it could be a positive. I DON'T know the answer. This is just a tip for you
