It would be a decrease. If it were 25 to 75 it would be an increase. But, sine it is 75 to 25 the answer would be decrease.
Answer:
$7 200
Step-by-step explanation:
Amount of money paid for charity = 
× $22 000
= $2 200
Remaining money left for children = $22 000 - $2 200 - $10 800
= $9000
Let the amount of money her son receives be x and the amount her daughter gets be 4x.
Son's $ + Daughter's $ = $9000
x + 4x = 9000
5x = 9000
Amount of money her daughter gets (4x) = 
× 9000
= $7 200
Answer:
f(-3) = 27
Step-by-step explanation:
f(x) = (-x)^3
We want the value when x =-3
Substitute this in
f(-3) = (--3)^3
f(-3) = 3^3
f(-3) = 27

Answer:
779.4 square units
Step-by-step explanation:
You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.
One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...
A = (1/2)r²sin(α)
Since there are n such triangles, the area of the n-gon is ...
A = (n/2)r²sin(360°/n)
__
For a hexagon (n=6) with radius 10√3, the area is ...
A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units
