Answer:

2

Step-by-step explanation:

It's 2 because as you can see in the botton 4/10 and 8/20, 4 x 2=8 and 10 x 2=20. It's like saying you're multiplying the same thing for the top and bottom of both fractions. So, the two fractions on the top with the juice is getting multiplied by 4.

Answer:

2

Step-by-step explanation:

24÷6=4

knowing this you then divide 8 by 4 to get the numerator

8÷4=2

If there are 30 pink flowers the number of purple flowers will be 45.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that the ratio of pink flowers to purple flowers is 4 to 6 and there are 30 pink flowers,

The number of purple flowers will be calculated as,

4/30 = 6/x

Solve for x

4x=180

X=45

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: 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.

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:

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:

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
