First one is B) 90
for the rest you need to slide the paper over and do a new picture. leave out the side with the hole punches and include the words :)
The given sequence is 4,12,36,108....
Here we can observe the first term = 4 , and so on.
The common ratio (r)=
Since the common ratio is greater than 1,
Therefore the sum of the geometric series =
Since we have to find the sum of first seven terms, so n=7
=
=4372.
Therefore, option C is the correct answer.
Answer:
7.40
Step-by-step explanation:
Divide 185 by 25 to get unit rate
Answer:
Step-by-step explanation:
1. slope=-3/2-3 is at the top,2 is at the bottom
y intercept=4-The y intercepts or goes past at 4,
equation=y=-3/2+4-We put it all together and we get y=-3/2+4!
2. slope=-3/2-It starts at 3 again,and ends at two again.
y intercept=0-The y touches the line at 0,or the middle
equation=y=-3/2-y equals the slope and we subtract y.
We can set up a proportion here. On map scales, the scale goes like:
“1 (length on the map) : x (real life length)”
Here, we have 2 : 8. We need to make it so the first number is 1, because thats easier for measuring.
2 : 8 /divide both sides by 2
1 : 4
The scale would be 1in : 4mi (in other words, 1 inch on the map corresponds to 4 miles in real life).
