Answer:

[tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]

[tex]4\dfrac{1}{4}\ \text{inches}[/tex]

Step-by-step explanation:

w = Width of a stamp = [tex]\dfrac{7}{8}\ \text{inch}[/tex]

l = Length of a stamp = [tex]1\dfrac{1}{4}\ \text{inch}[/tex]

Area is given by

[tex]A=lw\\\Rightarrow A=\dfrac{7}{8}\times 1\dfrac{1}{4}\\\Rightarrow A=\dfrac{7}{8}\times \dfrac{5}{4}\\\Rightarrow A=\dfrac{35}{32}\\\Rightarrow A=1\dfrac{3}{32}\ \text{inches}^2[/tex]

The area of each stamp is [tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]

Perimeter is given by

[tex]P=2(l+w)\\\Rightarrow P=2(\dfrac{7}{8}+\dfrac{5}{4})\\\Rightarrow P=2\times \dfrac{17}{8}\\\Rightarrow P=\dfrac{17}{4}=4\dfrac{1}{4}\ \text{inches}[/tex]

The perimeter of each stamp is [tex]4\dfrac{1}{4}\ \text{inches}[/tex].

Answer:

254.34 cm²

Step-by-step explanation:

A = πr2 Use the formula.

A = π(9)2 Substitute. Use 9 for r.

A ≈ 3.14 × 92 Substitute. Use 3.14 for π.

A ≈ 3.14 × 81 Evaluate the power.

A ≈ 254.34 Multiply.

I doubled checked the correct awnser is D

The solution for x of the inequality x-c/d > y (for d > 0) is x > d * y + c.

Here,

To solve the inequality for x, we'll isolate x on one side of the inequality:

Given inequality: (x - c) / d > y

First, we'll multiply both sides of the inequality by d to get rid of the fraction.

Remember that since d > 0, we don't need to reverse the inequality:

d * [(x - c) / d] > d * y

Next, the d on the left side cancels out, and we have:

x - c > d * y

Now, to isolate x, we'll add c to both sides of the inequality:

x - c + c > d * y + c

x > d * y + c

So the solution for x is x > d * y + c.

Answer:1. (200-2L)/2      2.L x (200-2L)/2=A

Step-by-step explanation:

Answer:

Part 1)

[tex]W=100-L[/tex]

Part 2)

[tex]A(L)=L(100-L)[/tex]

Step-by-step[tex]W = 100-L[/tex] explanation:

We are given a rectangle with a perimeter of 200 feet.

Part 1)

The formula for perimeter for a rectangle is:

[tex]200=2(L+W)[/tex]

We can divide both sides by 2:

[tex]100=L+W[/tex]

And subtracting L from both sides yields:

[tex]W=100-L[/tex]

Part 2)

The area of a rectangle is given by:

[tex]A(L)=LW[/tex]

Since we solved for W earlier:

[tex]A(L)=L(100-L)[/tex]

Answer:

76. hope it helps.................

Answer:

Option B is correct.

Step-by-step explanation:

Total bill = $48

Tip = 20%

Amount of tip = 20% of 48

Amount = [tex]\frac{20}{100}*48[/tex]

Amount = 0.2 * 48

Amount = $9.60

Total bill with tip = 48 + 9.60 = $57.60

Dividing by 2 as they are spliting the bill.

Each pays = [tex]\frac{57.60}{2}=28.80[/tex]

Therefore,

Option B is correct.

The expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n² - 81.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

A.
4n² - 81,
This can be factored as (2n - 9)(2n + 9), which is of the form (ax + b)(ax - b).

B.

2n² - 49,
This can be factored as (n - 7√2)(n + 7√2), but not in the form (ax + b)(ax - b).

C.

2n² + 49:

This cannot be factored into the form (ax + b)(ax - b) using rational numbers. We can factor it over the complex numbers as (n + i√49/2)(n - i√49/2), where i is the imaginary unit, but this does not satisfy the conditions of the problem.

D.

4n² + 81,
This cannot be factored into the form (ax + b)(ax - b)

Therefore, the expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n2 + 81.
