Answer:
10
Step-by-step explanation:
The number of tiles in the design is 1 + 2 + 3 + ...
We can model this as an arithmetic series, where the first term is 1 and the common difference is 1. The sum of the first n terms of an arithmetic series is:
S = n/2 (2a₁ + d (n − 1))
Given that a₁ = 1 and d = 1:
S = n/2 (2(1) + n − 1)
S = n/2 (n + 1)
Since S ≤ 60:
n/2 (n + 1) ≤ 60
n (n + 1) ≤ 120
n must be an integer, so from trial and error:
n ≤ 10
Mr. Tong should use 10 tiles in the final row to use the most tiles possible.

Answer: 280 = x
Step-by-step explanation: Okay you are using this equation! y = kx But you must rearrange it!
When rearranged you get y/x = k
Plug in x and y!
y/x = k
35/140 = k
0.25 = k
Now find the value of x.
You use this formula now, y/k = x
Plug in k from the last problem and y = 70
y/k = x
70/0.25 = x
280 = x
Answer:
Step-by-step explanation:
Base on the question where as asking to state the translation vectors could have been used for the pair of figures, base on my research, I would say that the answer would be arrow pointing to the right.
Answer:
Step-by-step explanation:
peter can buy pack of nine pencils
6 divided by 1.68 =3.5
9 divided by 2.34=3.8
