Answer:
P = 96
A = 575
Step-by-step explanation:
basically dialating a figure is making it smaller or larger by a certain amount and in this case it is 6 so you have to make each side of your square 6 times larger so each side would be 24 (of whatever unit you are using) so then you would calculate it by doing 24*24 to find the area and 24*4 to find the perimeter.
Answer:
There is no problem stated, but here is the x's for every equations provided:
Step-by-step explanation:
a.) x²+2=36
x²=34
x=√34
b.) 2x + 2 =36
2x= 34
x= 17
c.)2x=36
x= 18
d.) 2x+1=36
2x=35
x=35/2
Answer: 1. X=4
2. X=12
3. X=5
4. B=1
Step-by-step explanation:
Answer:
16.07 milligrams
Step-by-step explanation:
From the question,
Using the formula of radioactive decay,
R/R' = 2ᵃ/ᵇ..................... Equation 1
Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.
Make R' the subject of the equation
R' = R/(2ᵃ/ᵇ)................ Equation 2
Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days
Substitute these values into equation 2
R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)
R' = 100/(6.222)
R' = 16.07 milligrams of plonium-210
