Answer:
The homeowner will require 9 strips of wallpaper.
Step-by-step explanation:
The question is asking <em>"how many 20 inches fit into 15 feet?".</em>
We know that
1 foot = 12 inches;
therefore, 15 feet will be
15 ft * 12 in/ft = 180 in.
Now, the number of 20 inches wallpaper strips that will fit into 180 in long wall will be
180 in/ 20 in = 9
Therefore, the homeowner will require 9 strips of wallpaper.
Answer:
r ≅ 3.00
Step-by-step explanation:
First we need to get the formula for finding the volume of sphere. The formula is:
Now to find for the radius, we need to input the value that we know into the formula.
Now we multiply both sides by 3/4.
Now divide both sides by π.
To find r, we finally get the cube root of both sides.
![\sqrt[3]{r^{3} }= \sqrt[3]{27.01}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E%7B3%7D%20%7D%3D%20%5Csqrt%5B3%5D%7B27.01%7D)
r ≅ 3.00
Answer:
22.5 years to the nearest tenth.
Step-by-step explanation:
The equation is
6000 = 4000(1 + 0.018/12)^12t where t = the number of years
(1 + 0.018/12)^12t = 1.5
1.0015^12t = 1.5
Taking logs:
12t log 1.0015 = log 1.5
12t = log 1.5 / log 1.0015
12t = 270.51
t = 22.54 years.
