The question is asking to state the first twelve number in the pattern in the number, base on my calculation, I would say that the first twelve numbers are 7, 8, 9, 10, 11, 12, 13, 14 ,15 ,16, 17, and 18. I hope you are satisfied with my answer and feel free to ask for more if you have questions
Answer:
18 pi sqrt(2)
Step-by-step explanation:
We know the sides of a Pythagorean triangle
a^2 + a^2 = c^2
18^2 + 18^2 =c^2
2 * 18^2 = c^2
Taking the square root of each side
c = 18 sqrt(2)
This is the diameter of the circle
We want to find the circumference
C = pi * d where d is the diameter
C =pi* 18 sqrt(2)
Answer:

see in the picture, E is the centre of the kite
1) AC = 2.EC = 40
2) CD = sqrt( ED² + EC² ) = sqrt(21² + 20²) = 29
3) ABE = 90⁰ - 51⁰ = 39⁰
4) BCE = BAE = 51⁰
<u>p</u><u>a</u><u>r</u><u>t</u><u> </u><u>2</u><u>:</u>
we have:
3x + 7 = (3x - 1 + 8x)/ 2
<=> 3x + 7 = 5.5x - 0.5
<=> 2.5x = 7.5
<=> x = 3
5) with x = 3 => UV = 3.3 - 1 = 9 - 1 = 8
6) XY = 3.3 + 7 = 9 + 7 = 16
7) TW = 8.3 = 24

we have:
28.5 = (x + 25)/2
<=> x + 25 = 57
<=> x = 32
Set this up as a proportion with seeds on top and plants on bottom. Ours will look like this:
. Cross multiply to get 12x=1092. Divide to get that the number of plants to expect from 156 seeds is 91, choice B from above.
