You subtract 21 from 34, which leads you to -13 degrees F
The total area of the parallelogram is 242
Step by step:
A = b h = 22 x 11 = 242
Answer:
It would be 1/625
Step-by-step explanation:
5^-4=0.0016
0.0016 as a fraction is 1/625
Hope this helps! :)
Answer:
V = 564.2 m^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height
V = 1/3 pi (7)^2 (11)
V =539 /3 * pi
Letting pi be approximated by 3.14
V = 564.1533333 m^3
Rounding to the nearest tenth
V = 564.2 m^3
Suppose that it will take n years for Dave's investment to be equal to Len's;
thus using the compound interest formula we shall have:
A=p(1+r/100)^n
thus the investment for Len after n year will be:
A=5200(1+3/100)^n
A=5200(1.03)^n
The total amount Dave's amount after n years will be:
A=3600(1+5/100)^n
A=3600(1.05)^n
since after n years the investments will be equal, the value of n will be calculated as follows;
5200(1.03)^n=3600(1.05)^n
5200/3600(1.03)^n=(1.05)^n
13/9(1.03)^n=(1.05)^n
introducing the natural logs we get:
ln(13/9)+n ln1.03=n ln 1.05
ln(13/9)=n ln 1.05-n ln 1.03
ln(13/9)=0.0192n
n=[ln(13/9)]/[0.0192]
n=19.12
thus the amount will be equal after 19 years
