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]

Answer:

A

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

A 1 2-liter bottle for $0.89

1 liter = .89 /2 = $0.445

B 3 1-liter bottles for $1.50

1 liter = $1.50/3 = $0.50

C 24 0.5-liter bottles for $5.25

1 liter = 5.25 / 12  = $0.4375

D 36 0.25-liter bottles for $4.75

1 liter = $4.75 / 9  = $0.53

Give me brainllest

Answer:

C is the best buy

Step-by-step explanation:

0.89/2 = 0.445

3 * 1 litre bottles = 3 litres

1.50/3 = 0.5

24 * 0.5 litres = 12 litres

5.25/12 = 0.4375

36 * 0.25 liters = 9 liters

4.75/9 = 0.52777777

Answer:

55 bricks

Step-by-step explanation:

First find the area of one brick by multiplying 10x6x4, which is 240 cm^3. Then divide that from 13,200 which gives you 55 bricks.

Answer:

55 bricks

Step-by-step explanation:

First, we know they used 13,200 cm^3 of concrete. cm^3 is a volume, so in order to find how many bricks can be made, we must find the volume of each brick. Multiply the dimensions of each brick. 10*6*4=240cm^3. Now, divide 13,200cm^3/240cm^3=55 bricks

Answer:

1) The store selling for 1.1 per 3 lbs

2) $6.24

Step-by-step explanation:

1)

1.1/3 = 0.37

0.78/2 = 0.39

0.37 is cheaper so it's a better deal

2)

[tex]\frac{0.78}{3} =\frac{x}{24} \\\\3x=18.72\\x=6.24[/tex]

Answer:

1.10 for 3 is the better deal.  It will cost $6.24 for the pencils.

Step-by-step explanation:

Do two separate problems but find how much it is for 1 carrot.  So the first is:$1.10 divided by 3 carrots = .366 or 37 cents per carrot.

The second one is: .78 divided by 2 carrots = .39 cents per carrot.

If you break 24 students into groups of 3, that would be 8 groups. 24 divided by 3 = 8.  

8 sets of 3 pencils is .78 x 8 = $6.24

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%

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…9ℓtimes , 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: 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.

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.
