Given:

Perimeter of a square = [tex]32x-12.8[/tex]

To find:

The side length of the square.

Solution:

We know that, the perimeter of the square is 4 times of its side length.

[tex]P=4a[/tex]

Where, a is the side length.

Perimeter of a square = [tex]32x-12.8[/tex]

Now,

[tex]4a=32x-12.8[/tex]

Divide both sides by 4.

[tex]a=\dfrac{32x-12.8}{4}[/tex]

[tex]a=\dfrac{32x}{4}-\dfrac{12.8}{4}[/tex]

[tex]a=8x-3.2[/tex]

Therefore, the side length of the square is [tex]8x-3.2[/tex] units.

Answer:

v>2/3

Step-by-step explanation:

2(4−1)<2(3v+1)

Step 1: Simplify both sides of the inequality.

6<6v+2

Step 2: Flip the equation.

6v+2>6

Step 3: Subtract 2 from both sides.

6v+2−2>6−2

6v>4

Step 4: Divide both sides by 6.

6v/6>4/6

v>2/3

Answer:

v>2/3

Step-by-step explanation:

Switch sides: 2(3v+1)>2(4-1)

Ope the brackets and multiply

6v+2)>2*3

Subtract 2 on both sides

6v>6-2

6v>4

v>4/6

v>2/3

Answer:

The sixth term is -3,072

Step-by-step explanation:

Here, we want to get the 6th term

From the question, the first term is -12

the common ratio would be -12/3 = -4

So the sixth term will be;

ar^5

= 3 * (-4)^5 = -3072

Answer:

$5

Step-by-step explanation:

We are given that  profit equation

[tex]P(x)=-2x^2+20x+0[/tex]

Where x=Charges per pair of mittens

We have to find the charge per pair of mittens to make her max profit.

Differentiate equation w.r.t x

[tex]\frac{dP}{dx}=-4x+20[/tex]

[tex]\frac{dP}{dx}=0[/tex]

[tex]-4x+20=0[/tex]

[tex]4x=20[/tex]

[tex]x=5[/tex]

Again differentiate w.r.t x

[tex]\frac{d^2P}{dx^2}=-4<0[/tex]

Hence, the profit is maximum at x=5

Lily should charge $5 per pair of mittens to make her max profit .

Answer:

Answer in explanation

Step-by-step explanation:

To calculate the monthly loan payment, she needs to have the total payment value

She can then proceed to divide the total payment value by the number of months in which she is to repay the loan

In further terms, what we mean here is that she needs to add the loan interest value to the amount of its principal ( this is based on the type of finance she has)

Then, the cumulative loan value is then divided by the number of months that is present in the number of years for which she is to make repayment for the loan amount

Let the missing number be X.

Set up the equation:

x/3i = 11-2i

Solve for x by multiplying both sides by 3i

x = 33i + 6

Answer:

71.5

Step-by-step explanation:

To find the median score you have to find the number in the middle.

First put them in the ascending order: 69,70,71,72,73,74

Now take away one from each side:

70,71,72,73

You are left with these numbers: 71,72

Now to find the median add them: 71 + 72 = 143

Then divide your answer always by 2:

143 ÷ 2 = 71.5

Here is another example: 3,1,2

Ascending order: 1,2,3

Now take away one from each side and you will be left with 2

Answer:

The width of each bedroom is 12 feet.

Step-by-step explanation:

Each bedroom has 2 walls 13 feet long. That is a total of 8 times 13, which equals 104.

Subtract 104 from 200. That leaves 96 feet to be divided into the 8 widths.

96 ÷ 8 = 12.

12 feet is the width of each bedroom.

Answer:

Solving |-7-1| we get 8

Step-by-step explanation:

We need to solve |-7-1|

Absolute value is non-negative number even the number has negative sign.

So, |a| = a or |-a|=a

So, solving |-7-1|

=|-8|

=8

So, Solving |-7-1| we get 8

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

5.2v - (30 ÷ 6) + 12

9) We need to determine which part of the expression represents a​ quotient?

We know that when we divide one rational expression by another, the result would be termed as 'quotient'.

Here, it is clear that:

(30 ÷ 6) represents the expression part for a quotient.

When we divide 30 by 6, we get the result 5 which would be the quotient of the expression 30 ÷ 6.

10. Which part of the expression represents a product of two​ factors?

We know that when a multiply two number, we get the product. The multiplying numbers are the factors of the product.

For example, 4 × 9 = 36 therefore, 4 and 9 are the factors of 36.

In our case, 5.2v represents a product of two​ factors 5.2 and v. In other words, 5.2 and v are the factors of the product of 5.2v.

Answer:

The original amount invested in bond is $5,400.

Step-by-step explanation:

Given:

Interest on stocks = 6%, or 0.06

Interest on stocks = 8%, or 0.08

Let A represents the original amount invested in stocks and B represents the original amount invested in bonds. We can therefore have original income as follows:

0.06A + 0.08B = $684 .................... (1)

Sine Malenie's income would decrease by $24 if the investments were interchanged, this implies that we will have:

0.08A + 0.06B = $684 - $24

0.08A + 0.06B = $660 ................. (2)

From equation (2), we can solve for A as follows:

0.08A = $660 - 0.06B

Divide through by 0.08, we have:

A = $660/0.08 – (0.06/0.08)B

A = $8,250 – 0.75B

Substituting A = $8,250 – 0.75B into equation (1) and solve for B, we have:

0.06($8,250 – 0.75B) + 0.08B = $684

$495 – 0.045B + 0.08B = $684

Rearranging, we have:

– 0.045B + 0.08B = $684 - $495

0.035B = $189

B = $189 / 0.034

B = $5,400

Therefore, the original amount invested in bond is $5,400.

Answer:

n = 5

Step-by-step explanation:

First write the equation

1 + n = 6

Second move the n and use the opposite symbol

n = 6 - 1

this will get you

n = 5
