Answer:
6 different wallpapers
Step-by-step explanation:
Given
[tex]Colours = 27[/tex]
[tex]Textures = 14[/tex]
[tex]Total = 2268[/tex]
Required
Determine the number of different wallpapers he can choose from
From the question, he can choose 1 from 27 colors;
The number of ways is:
[tex]Colours = ^{27}C_1 = \frac{27!}{(27 - 1)!*1!} = \frac{27!}{26!*1!} = = \frac{27*26!}{26!*1} = 27[/tex]
From the question, he can choose 1 from 14 textures;
The number of ways is:
[tex]Textures = ^{14}C_1 = \frac{14!}{(14 - 1)!*1!} = \frac{14!}{13!*1!} = \frac{14*13!}{13!*1} = 14[/tex]
Assume the total number of wallpapers is x and he can only select 1.
The number of ways of selection is:
[tex]Wallpapers = ^{x}C_1 = \frac{x!}{(x - 1)!*1!} = \frac{x* (x - 1)!}{(x - 1)!*1!} = x[/tex]
So, the total selection is:
[tex]Colours * Textures * Wallpapers = Total[/tex]
[tex]27 * 14* x= 2268[/tex]
[tex]378* x= 2268[/tex]
Divide both sides by 378
[tex]\frac{378* x}{378}= \frac{2268}{378}[/tex]
[tex]x= \frac{2268}{378}[/tex]
[tex]x= 6[/tex]
Hence, the number of different wallpaper is 6
Volume of a cylinder the radius Is 5ft the height is 10ft
Answer:
V = 785.7ft³
Step-by-step explanation:
V = π r² h
V = 22/7 (5) 10
V = 22/7 × 25 ×10
V = 22/7 × 250
V = 22 × 250 ÷ 7
V = 550 ÷ 7
V = 785.7ft³ answer
Answer: The volume of the cylinder is 785.7ft³

What is the polar form of 7 StartRoot 3 EndRoot minus 7 i?
In polar form the expression is ( 14 , 30 )
How the rectangular form is converted to Polar form ?To convert the expression x +iy to polar form ( r , [tex]\rm \theta[/tex] ) , the standard equations used are
r = [tex]\rm \sqrt {x^2 + y^2}[/tex]
tan [tex]\rm \theta[/tex] = y/x
The given expression is
7 √3 - 7i
x = 7 √3
y = -7
r = [tex]\rm \sqrt {(7\sqrt{3})^2 +(-7)^2}[/tex]
r = √196
r = 14

What is the image of (4,−8) after a dilation by a scale factor of 1/4 centered at the origin?
Answer:
(1,-2)
Step-by-step explanation:
you just have to multiply the coordinates by 1/4
4x1/4=1
-8x1/4=-2
so the new coordinates are (1,-2)
The image of the given point is (1,-2).
Important information:
The coordinates of the point are (4,-8).Point is dilated by a scale factor of [tex]\dfrac{1}{4}[/tex] centered at the origin.Dilation:If a point is dilated by a scale factor of [tex]k[/tex] centered at the origin, then the rule of dilation is defined as:
[tex](x,y)\to (kx,ky)[/tex]
Using the above rule, we get
[tex](4,-8)\to \left(\dfrac{1}{4}(4),\dfrac{1}{4}(-8)\right)[/tex]
[tex](4,-8)\to \left(1,-2\right)[/tex]
Therefore, the image of the given point is (1,-2).

Maria was approved for a 10-year, Federal Unsubsidized student loan in the
amount of $17,700 at a rate of 3.9%. Loan repayment will begin after 4.5
years.
Answer:
3796.65
Step-by-step explanation:
I = $ 3,106.35
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.9%/100 = 0.039 per year,
then, solving our equation
I = 17700 × 0.039 × 4.5 = 3106.35
I = $ 3,106.35
The simple interest accumulated
on a principal of $ 17,700.00
at a rate of 3.9% per year
for 4.5 years is $ 3,106.35.
$ 6,903.00 - 3,106.35 = 3796.65

How to solve 6x + y= -5, -6x + 12y=96 using elimination and does it have no solution or many solutions?
Answer:
x = -2
Step-by-step explanation:
Arrange 6x + y= -5, -6x + 12y=96 vertically:
6x + y= -5
-6x + 12y=96 Now combine like terms:
--------------------
13y = 91
Solving for y by dividing both sides by 13: y = 7
Find x by substituting 7 for y in the second equation: -6x + 12(7) = 96
Then -6x = -84 + 96, or:
-6x = 12, and so x = -2
