Erik buys 2.5 pounds of cashews. If each pound of cashews costs $7.70, how much will he pay for the cashews?
2 answers:
Erik will pay for the cashews : = $19.25 pounds
<h3>Further explanation </h3>Comparison is an effort to compare two or more objects in terms of shape or size, or number
Proportional Comparisons are comparisons of two or more numbers where one number increases, the other numbers also increase
Can be formulated
so that if:
x = 2
then
While the reversal value comparison is the comparison of two or more numbers where one number increases, the other number decreases in value
Can be formulated
so that if:
x = 2
then
Erik buys 2.5 pounds of cashews
each pound of cashews costs $7.70
So there is Proportional Comparisons
1 pound = $7.70
2.5 pound = ?
So he will pay for the cashews :
= 2.5 pounds x $7.70
= $19.25 pounds

Step-by-step explanation:
The simplest method is "brute force". Calculate each term and add them up.
∑ = 3(1) + 3(2) + 3(3) + 3(4) + 3(5)
∑ = 3 + 6 + 9 + 12 + 15
∑ = 45
∑ = (2×1)² + (2×2)² + (2×3)² + (2×4)²
∑ = 4 + 16 + 36 + 64
∑ = 120
∑ = (2×3−10) + (2×4−10) + (2×5−10) + (2×6−10)
∑ = -4 + -2 + 0 + 2
∑ = -4
4. 1 + 1/4 + 1/16 + 1/64 + 1/256
This is a geometric sequence where the first term is 1 and the common ratio is 1/4. The nth term is:
a = 1 (1/4)ⁿ⁻¹
So the series is:
5. -5 + -1 + 3 + 7 + 11
This is an arithmetic sequence where the first term is -5 and the common difference is 4. The nth term is:
a = -5 + 4(n−1)
a = -5 + 4n − 4
a = 4n − 9
So the series is:

The height equation is:
Where is the initial height of the book, which is 5, so we can write:
Now, we want time it took for the book to reach ground (h = 0)
So, we substitute h = 0 and solve for t:
It took about 0.559 seconds for the book to reach the ground
