Answer:
1.03
Step-by-step explanation:
To find the volume of a prism, find the area of the base and multiply it by the height.
The base is an octagon. The area is found . Substitute a = 0.5.
The volume is 1.21*2.5 = 3.025.
However, there are three holes drilled out half way which each have volume 0.06.
The volume is found as V = πr²h. Substitute r = 0.125 which is half the diameter of 0.25. Since they go half way, the height is h = 1.25.
V = π(0.125)²(1.25) = 0.06.
Since there are 3, they equal 3*0.06 = 0.18.
Subtract this from the volume.
1.21 - 0.18 = 1.03
Answer:
Step-by-step explanation:
The time constant of the isotope is:
The decay of the isotope is described by the following model:
Now, the time is cleared in the equation:
PART ONE:
To put this information into a fraction you write part over whole:
To change this into a decimal you have to plug in 8÷40 into your calculator:
0.2
PART TWO:
After you subtract 8 from 40, there are 32 fifth graders left.
The fraction will look like this:
To change this into a decimal you have to plug in 32÷40 into your calculator:
0.8
