Which expression shows the area of the base of each pyramid? (One-fourth x) squared in.2 (One-third x) squared in.2 (One-half x) squared in.2 x2 in.2
Answer:
(a) [tex]Area = (\frac{x}{4})^2[/tex]
Step-by-step explanation:
The question is incomplete. (See comment for complete question).
From the completed question, we have:
[tex]Total\ base\ length = x[/tex]
[tex]n = 8[/tex] --- number of pyramids
Required
An expression for the area of the base
The total base length of the pyramid represents the perimeter of the base.
And since the base is a square, then the following relationship exist.
[tex]Total\ base\ length = 4L[/tex]
Where L represents the length of each side.
This gives
[tex]4L = x[/tex]
Make L the subject
[tex]L = \frac{x}{4}[/tex]
The area of the base is then calculated as:
[tex]Area = L^2[/tex]
[tex]Area = (\frac{x}{4})^2[/tex]

Will mark branliest. What can the maximum number of digits be in the repeating block of digits in the decimal expansion of 1/17?
Answer:
Step-by-step explanation:
Let n=2α⋅5β⋅m , where gcd(m,10)=1 . Then, the decimal expansion of 1n is of the form
0.a1…akak+1…ak+ℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(1) ,
where k=max{α,β} and ℓ is the least positive integer for which m∣(10ℓ−1) . In other words, ℓ is the order of 10 in the multiplicative group of units modulo m . So ℓ∣ϕ(m) by Lagrange's theorem.
In particular, if gcd(n,10)=1 , then α=β=k=0 , m=n , and
1n=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(2)
Therefore, we know that
117=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(3)
Here ℓ is the least positive integer for which 17 divides 9…9ℓtimes , and we know that ℓ divides ϕ(17)=16 .
Successively squaring 10 modulo 17 gives
102≡−2(mod17),104≡4(mod17),108≡−1(mod17),1016≡1(mod17) .
So ℓ=16 in expansion (3) .
In fact,
a1…a16×17=1016–1.
a1…a8+a9…a16=108−1 .
The first fact has nothing to do with the denominator n being prime. The second fact has everything to do with n being prime, and was discovered by E. Midy in 1836 .

Answer:
x= 17
Step-by-step explanation:
5x-7=3x+27
move 3x to other side by doing the oppostie (subtracting 3x)
5x-7-3x=27
2x-7=27
move -7 to other side by adding it (to the other side)
2x= 7+27
2x= 34
divide by 2 (on both sides) to get x by itself
2x/2=34/2
x= 17

Brand A: 6 eggs $1.77
Brand B: 12 eggs $3.75
Brand : 18 eggs $5.24
Brand D: 24 eggs $7.10
Assuming all the eggs are of similar quality, which decision should Regina make if she wants to get the best price per egg?
Help
Answer:
Brand C
Step-by-step explanation:
Brand A: 1.77/6=$0.30
Brand B: 3.75/12=$0.31
Brand C: 5.24/18=$0.29
Brand D: 7.10/24=$0.30
Based on the price per egg of each brand (calculated above), the best price per egg would be brand C.

Which expression represents the relationship between the step number n and the total number of small squares in the pattern?
A pattern of small squares. Step 1 has 0 squares. Step 3 has 3 squares: 2 by 2 but missing the lower right square. Step 3 has 8 squares: 3 by 3 but missing the lower right square.
A.
B.
C.
D.
Answer: n squared - 1
Step-by-step explanation:
The relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.
What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given is a pattern of small squares as described -
Step 1 has 0 squares.
Step 2 has 3 squares : 2 by 2 but missing the lower right square.
Step 3 has 8 squares : 3 by 3 but missing the lower right square.
We can write the general expression for step {n} as -
Step {n} will have : 2ⁿ - 1 squares with missing the lower right square.
or
f(n) = 2ⁿ - 1
Therefore, the relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.

Kelly deposited $4,205 in an account for 3.5 years. She earned $662.29 in interest. What interest rate did the bank pay her?
Answer:
r = 4.5%
Step-by-step explanation:
Formula:
I = Prt
r = I/(Pt)
Given:
I = 662.29
P = 4205
t = 3.5
Work:
r = I/(Pt)
r = 662.29/(4205 * 3.5)
r = 662.29/14717.5
r = 0.045
r = 4.5%
