How many squares do I have to draw in(10 x 10 grid) for the percentage of 57.74%??

Afina-wow [57]

Answer:

There is obviously only 1 10x10 square. If we start with a 9x9 square in the top left corner, we can move it down 1, across 1 and back up 1, so there are 4 possible 9x9 squares.

For 8x8 we can move down 1, then 2 and we can move across 1 or 2 so that's 9 possible 8x8 squares.

For 7x7 we can go down 3 and across 3, so that's 4x4=16 possible squares.

The pattern is now clear the total number if squares is 1+4+9+16+…+100.

There's a formula for this, which I had to look up, but any the sum of the first n squared is 1/6n(n+1)(2n+1)1/6n(n+1)(2n+1), so the total number of squares is 10x11x21/6=5x11x7=385.

Type the correct answer in each box,

Sauron [17]

Answer:

The $n^{th}$ sequence aₙ = -15 +5n

The fifth term of the sequence

a₅ = 10

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given sequence

-10,-5,0,5,10,15,20,.....

The first term = -10

The difference of two terms in the given sequence is equal

d = -5-(-10) = -5 + 10 = 5

d = 0 -(-5) = 5

The given sequence is in arithmetic progression

<u><em>Step(ii):-</em></u>

The $n^{th}$ sequence

$a_{n} = a+(n-1) d$

aₙ = -10 +(n-1) 5

aₙ = -10 + 5n -5

aₙ = -15 +5n

<u><em>Step(iii):-</em></u>

The $n^{th}$ sequence aₙ = -15 +5n

put n = 5

a₅ = -15 + 5(5) = -15 +25 = 10

<u><em>Final answer:-</em></u>

The $n^{th}$ sequence aₙ = -15 +5n

The fifth term of the sequence

a₅ = 10

<u><em></em></u>
