Answer:

4 : 25

Step-by-step explanation:

Given the ratio of sides = a : b, then

ratio of areas = a² : b²

Thus

ratio of sides = 2 : 5, then

ratio of areas = 2² : 5² = 4 : 25

m_a_m_a [10]
For this question you would simply divide the number of bamboo poles by the number of feet which would be:
6,500/624= 10.41666666666667
Since it says to round to the nearest whole number,

Your answer would be about 10 bamboo poles per feet

Find the sum of (1-1/n) + (1-2/n) + (1 - 3/n)....upto n terms
bija089 [108]

Answer:

<em> (n - 1)/2</em>

Step-by-step explanation:

F = (1 - 1/n) + (1 - 2/n) + (1 - 3/n) + ...(1 - n/n)

  = (1 + 1 ... + 1) - (1/n + 2/n + 3/n + ...n/n)

     (there are n terms of 1)

  = n - (1 + 2 + 3 + ... + n)/n

  = n - [n x (n + 1)/2]/n

  = n - [n x (n + 1)]/[2 x n]

  = n - (n+1)/2

  = (2n - n - 1)/2

  = (n - 1)/2

Hope this helps!

Write the equation of the line passing through (2,-3) and parallel to y=4x-9.
maks197457 [2]

Answer:

y = 4x - 11 .

Step-by-step explanation:

The line y = 4x - 9 has a slope of 4 so our line will also contain 4x.

Using the point-slope form of the equation of a line:

y - y1 = m(x - x1)  ,   we have m = 4 and (x1, y1) = (2, -3):

y - -3 = 4(x - 2)

y + 3 = 4x - 8

y = 4x - 11  (answer).
