Answer:
72 percent
Step-by-step explanation:
7/25, x 4 to get a fraction of 100
28/100
100 - 28 = 72
72 percent
Answer:
Percent change is comparing one current number or value to another.
Percent difference is comparing a number or value to another number or value.

Answer:
The hypotenuse of a right triangle is 4m longer than the shorter leg and 2m longer than the longer leg. What are the lengths of the sides?
Just for variety, consider the hypotenuse = h, the short leg h-4 and the long leg h-2.
c^2 = a^2 + b^2; so h^2 = (h-4)^2 + (h-2)^2; h^2 = h^2 - 8h + 16 +h^2 -4h +4;
h^2 -12h +20 = 0 factors to (h - 10)(h - 2) = 0 so h = 2 or h = 10
Since (h - 2) = (2 - 2) = 0 and a triangle cannot have a side of zero length, 10 is the length of the hypotenuse.
h^2 = (h-4)^2 + (h-2); 10^2 = (10-4)^2 + (10-2); (10)^2 = (6)^2 + (8)
The hypotenuse is 10 cm, short leg 6 cm and long leg 8 cm.
Answer: 708017151.707 m^3
Step-by-step explanation:
Volume of a sphere has the equation of
V=4/3(pi)r*r*r=4/3(pi)r^3
r=553 m
4/3(pi)553*553*553=4/3(pi)553^3=4/3(pi)169112377
=676449508/3(pi)=225483169.333(pi)=708017151.707 m^3
Where pi=3.14
