52m^2= 2[(x-5)+(x)]. 52m^2= 2(2x-5). 52m^2=4x-10
Answer:
As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order to shift to a more stable configuration.
Step-by-step explanation:
Answer:
15 m
Step-by-step explanation:
The area of the circle is
A =pi r^2
A = pi 4^2 = 16 pi
The area of the sector is 30
The fraction is
30/16 pi
Take this time 2pi which are the radians of a circle
30 /16 pi * 2 pi = 15/4
This is the number of radians the angle is
The arc length is s = r * theta where theta is in radians
s = r theta
= 4 * 15/4
= 15
4.063 x 10 to the fourth power
11 / 2.75 = 4
2 * 2.75 = 5.5
11 - 5.5 = 5.5.
Milliw paid $5.50 more than she would have if she bought them on sale. The work should explain the answer. She spent $11 on 2.75 lbs of cheeries when she could've spent half of that on cherries which were on sale.
