It costs $6 for an 8 oz bag of chips. How much does 1 oz cost?
The cost of 1 oz of chip is $ [tex]\frac{3}{4}[/tex]
Given :
It costs $6 for an 8 oz bag of chips
Explanation
8 oz of chips cost $6
For example , If 5 pencils cost $10
then 1 pencil cost = [tex]\frac{10}{5} =2[/tex]
We are asked to find cost of 1 oz, so we divide the cost by the number of oz
8 oz of chips cost $6
1 oz cost =[tex]\frac{6}{8}=\frac{3}{4}[/tex]
The cost of 1 oz of chip =$ [tex]\frac{3}{4}[/tex]

The Great American Pyramid in Memphis, Tennessee, is a regular pyramid with a square base. Each
side of the base is about 544 feet long. The slant height is about 420 fest. Find the area of the
outside walls of this structure. Also, find the floor area.
Answer:
Area of 1 Face = slant Height * .5 * Base
Area of 1 Face = 420 * 272
Area of 1 Face = 114,240
Area of 4 Faces = 456,960 square feet
A good pyramid calculator is here: http://www.1728.org/volpyrmd.htm

Step-by-step explanation:
see answer above
can some one help me with geometric sequence?
Answer:
See below
Step-by-step explanation:
We have the series
[tex]$\sum _{ n=0 }^{ \infty }{ 3(0.8)^n}$[/tex]
(a) To show that the sum of first [tex]n[/tex] terms is [tex]S_n= 15(1-0.8^n)[/tex]
Consider that the this sum is given as
[tex]S_n = 3\dfrac { 1-{ r }^n}{ 1-r }[/tex]
In this case, the ratio is 0.8, thus, [tex]r=0.8[/tex]
[tex]S_n = 3\dfrac { 1-{ 0.8 }^n }{ 1-0.8 }[/tex]
[tex]3\dfrac { 1-{ 0.8 }^{ n } }{ 1-0.8 } = 15(1-0.8^n) \iff 3(1-{ 0.8 }^{ n }) = 15(1-0.8^n)( 1-0.8) \iff 3 = 15(1-0.8) \iff 3 = 15-12 = 3[/tex]
Therefore,
[tex]S_n = 3\dfrac { 1-{ 0.8 }^n }{ 1-0.8 } = 15(1-0.8^n)[/tex]
[tex]\dfrac{S_6}{S_4} = \dfrac{15(1-0.8^6)}{15(1-0.8^4)} = \dfrac{(1-0.8^6)}{(1-0.8^4)} = \dfrac{0.737856}{0.5904} = \dfrac{737856}{5904} = \dfrac{144\cdot 5124}{144\cdot 41} = \boxed{\dfrac{5124}{41} }[/tex]
(b) Calculate the smallest integer value of [tex]n[/tex] such that [tex]S_{40} -S_n < \dfrac{1}{2}[/tex]
Once [tex]S_{40} \approx 15 \text{ and } S_n>14.5, \text{ thus } S_{40} \approx S_n, \text{ but } n \text{ is considerably smaller than 40}[/tex]
I am considering [tex]S_{40}=15[/tex], so
[tex]15-15(1-0.8^n) < \dfrac{1}{2} \implies 0.8^n < 0.03 \implies n> 15.71[/tex]
[tex]\text{Once } n\in\mathbb{Z}, \text{ then } n=16[/tex]

f(x)=x^4+3, g(x)=x-7 and h(x)=square root of x then f(g(h(x))=
Answer:
x² - 28x√x + 294x - 1372√x + 2404
Step-by-step explanation:
f(x) = [tex]x^{4}[/tex] + 3
g(x) = x - 7
h(x) = √x
f(g(h(x))) - ?
g(h(x)) = √x - 7
f(g(h(x))) = [tex](\sqrt{x} -7) ^{4}[/tex] + 3 = ( √x - 7 )² × ( √x - 7 )² + 3 =
= (x - 14√x + 49)(x - 14√x + 49) + 3 =
= x² - 14x√x + 49x - 14x√x + 196x - 686√x + 49x - 686√x + 2401 + 3 =
= x² - 28x√x + 294x - 1372√x + 2404

Find (ƒ • g)(x) where ƒ(x) = x^2 + 2, g(x) = x – 3.
(ƒ • g)(x) = x3 – 3x2 + 2x – 6
(ƒ • g)(x) = x2 – x + 5
(ƒ • g)(x) = x3 – 6
(ƒ • g)(x) = x2 + x – 1
Answer:
x^3-3x^2+2x-6
Step-by-step explanation:
ƒ(x) = x^2 + 2
g(x) = x – 3
(ƒ • g)(x) = ( x^2 + 2) * (x – 3)
FOIL
= x^3 -3x^2 +2x -6
