Answer:
(4, 5 )
Step-by-step explanation:
Under a rotation about the origin of 180°
a point (x, y ) → (- x, - y ), thus
B(- 4, - 5 ) → (4, 5 )
X is 180 - 30 = 150,
The sum of the sides of a polygon is the (number of sides - 2) * (180) so the total interior angle measure of the right polygon is 360.
360 = 80 + 90 + 150 + y
x = 150
y = 40
1. Move all terms to one side
2x^2+3x+1=0
2. Find the numbers for a, b and c
a=2
b=3
c=1
3. Put the numbers into the formula
3^2-4(2)(1)
4. Simplify
9-4*2*1
9-8
1
We know that
[volume of the larger sphere]=[scale]³*[volume of smaller sphere]
scale=∛[volume of larger sphere/volume of smaller sphere]
scale=∛[64/27]-------> scale=4/3
the scale is equal to the<span> ratio of the length of the radio of these two spheres
so
the answer is
4/3</span>
477 x 5 = 2385
the average number adults are 2385
