Answer:

Step-by-step explanation:

2 methods you could use:

Method 1) Multiply both of the numbers together and divide by a hundred

20 * 80 = 1600/ 100 = 16

Method 2) Work out 10% and then 20%

10 % of 80 = 8

20 % of 80 = 16

Solve s=2(lw+lh+wh) for w

Scilla [17]

   s = 2(lw + lh + wh)

Divide each side by 2 :    s/2 = lw + lh + wh

Subtract 'lh' from each side:       s/2 - lh = lw + wh

Combine the 'w' terms:      s/2 - lh = w(l + h)

Divide each side by (l + h): (s/2 - lh) / (l + h) = w

Help is much needed!!!

Y - y1 = m (x + x1)

Solve for m by subtracting the y's and dividing them by the difference of the 2 x's.

-32 - 1 = -33
-8 - 3 = -11

Divide the two to get 3.

Use the first point (as instructed) and plug it into the equation.

y - (-32) = 3 (x - (-8))

y + [32] = [3] (x + [5])

The brackets are the fill in the blanks.

In a “Fibonacci” sequence of numbers, each term beginning with the third, is the sum of the previous two terms. The first number

Fed [463]

Answer:

8th term=107

Step-by-step explanation:

Here the sequence is following the 'fibonacci's sequence of numbers.....

i.e,Tn=T(n-1) +T(n-2), where n>2 but this sequence is not fibonnaci's number , it's not starting with 0, 1,1,2........

so you cannot apply formula to calculate,you have to find 8th term by simple calculation.....

Like here 3rd term is 9 and 1st term is 2

now 3rd term = 2nd term+1st term (sum of previous two terms)

i.e, 9= 2nd term +2

i.e, 2nd term =7

now, 4th term = 3rd +2nd

= 9+7=16

again, 5th term = 4th +3rd

=16+9=25

again,6th term =5th+4th

=25+16=41

again,7th term=6th+5th

=41+25=66

again,8th term=7th+6th

=66+41=107
