Let d represent the number of degrees in one angle of a regular polygon, and n represent the number of sides of the polygon to t

essellate. Which equation can be used to determine if the polygon will tessellate? 360° · n = d 360° · d = n 360° ÷ d = n n + d = 360°

to know if a polygon will tessellate one of the interior angles should be a factor of 360.

each angle of regular polygon = d = (n-2)*180

AVERAGE between 90 and 100%
means not including 90 and 100% but not including 90 or 100%


average=(sum of values in set)/(how many values in the set)

so
4 exams, so there are 4 values
average=(sum)/4

the sum is the known+unknwon
sum=76+99+86+x

so
90<span><</span>average and average <span><</span>100
or
90<span><</span>average<span><</span>100


lets say average=a

a=sum/number
a=(76+99+86+x)/4

90<(76+99+86+x)/4<100
90<(76+99+86+x)/4 and (76+99+86+x)/4<100

solve each for x and find intersection

90<span><</span>(76+99+86+x)/4
times 4 both sides
360<span><</span>261+x
minus 261 both sides
99<span><</span>x


(76+99+86+x)/4<u><</u>100
times 4 both sides
261+x<u><</u>400
minus 261 both sides
x<u><</u>139


so

99<u><</u>x<u><</u>139
since max score is 100
99<u><</u>x<u><</u>100

interval notaion is
[99,100]


answer is 2nd one

Given the point and it''s image, determine the scale factor. A (3, 6) A'' (4.5, 9) G'' (3, 6) G (1.5, 3) B (2, 5) B'' (1, 2.5).
Natasha2012 [34]
Put the value of the letters with " over the original
So for A we have 3 in the front and 4.5 for A"
4.5/3 = 1.5
We can check if this is actually the scale factor but using the other numbers
The second numbers for A and A" are 6 and 9
6 * 1.5 = 9
So for point A it is 1.5
Use the same thing for G. That gives you 2
For B, you get 0.5
So the scale factors are 1.5, 2, and 0.5
