Answer:
### What is Perimeter?

Perimeter of the drawing is 22 inches, **Perimeter** of the garden is 770 inches and the Perimeter of Garden becomes 35 times the Perimeter of drawing when drawing length and breadth is multiply by 35.

A closed route that covers, encircles, or outlines a one-dimensional length or a two-dimensional form is called a perimeter. A **circle**'s or an ellipse's circumference is referred to as its perimeter.

Perimeter of **Rectangle** = 2 ( Length + Breadth)

(a) Here Length of Drawing is 7 inches and Breadth of Drawing is 4 inches.

So, Perimeter of the drawing = 2( 7 + 4 )

= 2 * 11

= 22 inches.

(b) According to question , Length and Breadth of actual garden is 35 times of the length and breadth of drawing.

Therefore, Length of Actual garden = 35 * 7 = 245 inches

and, Breadth of Actual garden = 35 * 5 = 140 inches.

So, Perimeter of the garden = 2( 245 + 140 )

= 2 * 385

= 770 inches.

(c) The perimeter of Garden becomes 35 times the perimeter of drawing when drawing length and breadth is multiply by 35.

Solve the equation x/4 - 7 = y for x

Suppose you are an elementary school teacher. You want to order a rectangular bulletin board to mount on a classroom wall that has an area of 90 square feet. Suppose fire code requirements allow for no more than 30% of a classroom wall to be covered by a bulletin board. If the length of the board is three times as long as the width, what are the dimensions of the largest bulletin board that meets fire code?

2. Find the value of n

**Answer:**

**For 1:**** The first term is 10 and the common difference is **

**For 2:**** The value of n is 27**

**Step-by-step explanation:**

**The n-th term of the progression is given as:**

where,

is the first term, n is the number of terms and d is the common difference

**The sum of n-th terms of the progression is given as:**

where,

is the sum of nth terms

**For (1):**

**The 11th term of the progression:**

.......(1)

**Sum of first 4 numbers:**

......(2)

**Forming equations:**

( × 8)

**The equations become:**

**Solving above equations, we get:**

**Putting value in equation (1):**

**Hence, the first term is 10 and the common difference is **

**For 2:**

**The nth term is given as:**

**Solving the above equation:**

**Hence, the value of n is 27**

The value of n when the nth term of the **progression **is 49 is 22.

The 11th term of the progression (a11) is 25.

The sum of the first 4 terms (S4) is 49.

The nth term (an) is 49.

Let's find the answers to your questions:

Find the first term of the progression (a1) and the common difference (d):

We know that the nth term of an **AP** can be expressed as:

an = a1 + (n - 1)d

Substituting the values:

a11 = a1 + (11 - 1)d

25 = a1 + 10d

Now, we need to find a1 and d. We'll also use the information that the** sum** of the first 4 terms (S4) is 49. In an AP, the sum of the first n terms (Sn) can be expressed as:

Sn = (n/2)[2a1 + (n - 1)d]

For S4:

49 = (4/2)[2a1 + (4 - 1)d]

49 = 2[2a1 + 3d]

Now, we have two equations:

25 = a1 + 10d

49 = 2[2a1 + 3d]

Let's solve this system of **equations **to find a1 and d.

1. First, rearrange the first equation to isolate a1:

a1 = 25 - 10d

Now, substitute this expression for a1 into the second equation:

49 = 2[2(25 - 10d) + 3d]

Simplify and solve for d:

49 = 2[50 - 20d + 3d]

49 = 2[50 - 17d]

49 = 100 - 34d

34d = 100 - 49

34d = 51

d = 51/34

d = 3/2

2. Now that we have the common **difference** (d), we can find a1 using the first equation:

a1 = 25 - 10d

a1 = 25 - 10(3/2)

a1 = 25 - 15/2

a1 = (50 - 15)/2

a1 = 35/2

a1 = 17.5

So, the first term of the progression (a1) is 17.5, and the common difference (d) is 3/2.

Find the value of n when the nth term of the progression is 49:

We know that an = 49, and we can use the **formula **for an in an AP:

an = a1 + (n - 1)d

Substitute the values:

49 = 17.5 + (n - 1)(3/2)

49 - 17.5 = (n - 1)(3/2)

31.5 = (n - 1)(3/2)

To isolate n, multiply both sides by (2/3):

(n - 1)(3/2) = 31.5 * (2/3)

(n - 1) = 21

Now, add 1 to both **sides** to find n:

n = 21 + 1

n = 22

So, the value of n when the nth term of the progression is 49 is 22.

many inches of ribbon will she need?

24 inches

36 inches

A 156 inches B 120 inches

C90 inches

D 60 inches

The **amount **of **ribbon **needed is 120 inches

The **perimeter **formula for a **rectangle **states that P = (L + W) × 2, where P represents **perimeter**, L represents **length**, and W represents **width**.

Given:

**length **= 24 inches

**width **= 36 inches

So, **amount **of ribbon needed

=2(36+ 24)

=2(60)

=120 inches

Hence, the **amount **of **ribbon** needed is 120 inches
