quisiera ayudarte pero no hablo inglés :(
I am assuming you are trying to find the sum.
First, plug in n for 1, then n for 80 to get the following numbers:
5/6 and 163/6
As you go up the sequence, as n is increased by 1, then the next number is increased by 1/3
Use the arithmetic sequence formula to solve for the sum.
n * (a1 + a2)/2 where a1 is 1st number and a2 is last number.
80 * (5/6 + 163/6)/2
Simplify the expression to get 1120.
Answer:
D. (bottom right)
Step-by-step explanation:
A function is a relation where every input has an exact corresponding output.
So, a circle cannot be a function, neither can a vertical line.
If the graph in the top right contained a parabola the opened upwards instead of to the right, it could be a function. But in this case it isn't.
So, by process of elimination, it must be the bottom right graph!
Answer:
0.75
Step-by-step explanation:
Answer:
the scale is 630:1 = 0.16%
80inch^2 of 50400inch^2 however = 0.16%
Step-by-step explanation:
350ft^2 = 50400inches 8 x 10 = 80inches = 50400/80 = 630
50400/9 =5600 we distribute
5600/80 = 7
showing us that 7 x 9 = 63 where 63 x 80 = 5040 1/100th
1 = 630
7x9x 80 = 1/100 of 50400
0.01589 x 7x9x80x 7x9x80 = 80
Proves that every every 10000 the percentage goes down 0.00011%
