Answer:
The diameter of the bacterium is 4.05 times the diameter of the plant cell
Step-by-step explanation:
The given parameters both represent diameters
Plant Cell P = 1.26m
Bacterium B = 5.1m
First write out both expressions:
P = 1.26
B = 5.1
Divide B by P
5.1 / 1.26 = 4.04762 Round to 4.05
Multiply both side by P
P * B/P = 4.05 P
B = 4.05 P
This shows that the diameter of the bacterium is 4.048 times the diameter of the plant cell.
Answer:
4³×5² or 4³5²
Step-by-step explanation:
This is because there are three consecutive 4s, so you have to put the 4 into exponential form 3 times. So the exponential form for the 4s will be 4³. There are also 2 consecutive 5s so you have to include 2 in the exponential form. So, the exponential form of the 5s is 5². Now you have to somehow multiply them together. You could do this by putting a multiplication sign, (4³×5²) or you could bunch them together and it will mean the same thing (4³5²).
Hope this helps :)
Answer:
The value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95
Step-by-step explanation:
Cost of building 20 years ago = 12000000
We are given that the cost depreciated at 9% per year
Formula : 
Where N(t)= Population after t years
=Initial population=12000000
r= rate of depreciation=0.09
t = 20 years
Substitute the values in the formula:

N(t)=1819738.95
Hence the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95
Cos(angle) = adjacent/hypotenuse
Cos(angle) = 1.5/10
Angle = arccos(1.5/10)
Angle = 81.37 degrees
Although the angle is close, it is over the 80 degrees, so the inspector should be concerned.
Answer:
4 days
Step-by-step explanation:
She recorded date for 16 days, and 1/4 of the days were clear blue skies.
One way to find this is to multiply 16 and 1/4
16*1/4=4
Another way is to first convert 1/4 to a decimal
1/4=0.25
Then multiply 16 and 0.25
16*0.25 =4
So, 4 out of 16 days had clear blue skies
