7(2x - 3) = 1...distribute through the parenthesis
14x - 21 = 1.....step 1
14x = 22...step 2
x = 22/14 = 11/7 or 1 4/7
X - the total number of pages
There are 512 pages in the novel.
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.
Set up a proportion
x is the estimated number of returned phones. cross multiply to find x
12 x 2000 = 24000
350 x X = 350x
24000=350x
Divide
x=68.57
B.) 68
Answer:
The volume of the sculpture is 67.824 ft^3
Step-by-step explanation:
In this question, we are to calculate the volume of a conical sculpture, given the height of the sculpture and the circumference of the base.
Mathematically, the volume V of the sculpture is given by;
V =1/3 * π * r^2 * h
Now, we have the height directly from the question but we do not have the value of the radius.
We can obtain the value of the radius from the circumference of the base
Mathematically, the circumference C of the base of the cone is given by;
C = 2 * π * r
Inputing the value of the circumference, we have;
22.608 = 2 * 3.14 * r
r = 22.608/(2 * 3.14)
r = 22.608/6.28
r = 3.6 feet
Now plugging these values into the volume equation, we have
V = 1/3 * 3.14 * 3.6^2 * 5
V = 67.824 ft^3
