By mixing green and white
Answer:
2520
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference.
To find the number of terms given = - 10 , d = - 2 and a₁ = 100, then
100 - 2(n - 1) = - 10 ( subtract 100 from both sides )
- 2(n - 1) = - 110 ( divide both sides by - 2 )
n - 1 = 55 ( add 1 to both sides )
n = 56 ← number of terms
Given n, a₁ and a₅₆ , then the sun of the terms is
= (a₁ + a₅₆ )
= (100 - 10) = 28 × 90 = 2520
So count the total number of squares then count the ones that are shaded. For example in the diagram on the left there are 32 squares and there are 9 shaded. You would put 9/32
Vertices are basically the corners, so for the triangle PQR, it would be the last option
This is because if you picture a triangle in your head, there are three vertices,for corners, which would be p, q and r
