Answer:

Answer:

Perimeter of the given figure is :---

$(2n) + (2n) +( n + 5) + (n + 5) + (3n + 3) \n = 2n + 2n + n + 5 + n + 5 + 3n + 3 \n = \boxed{9n + 13}✓$

(9n+13) is the right answer

The slope of the points is closer to 0.5 thus y = 0.5x + 1.2 will be the best approximation thus option (B) is correct.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

As per the given points,

Let's take two-point (1,1) and (2,1.5)

The slope associated with the above points will be as,

(1.5 - 1)/(2 - 1) = 0.5

Thus, the line will be y = 0.5x + 0.3

Hence "The slope of the points is closer to 0.5 thus y = 0.5x + 1.2 will be the best approximation".

Ms. McDuffy bought 2 1/2 yards of fabric that cost $7.90 per yard. She also bought 3 3/4 yards of fabric that cost $9.96 per yard. What is the total cost of the fabric?

Answers

The total cost of the fabric is $57.1

What is unit rate?

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.

Given that, Ms. McDuffy bought 2 1/2 yards of fabric that cost $7.90 per yard. She also bought 3 3/4 yards of fabric that cost $9.96 per yard

Cost of fabric with unit rate = $7.90

= $7.90 × 5/2 = $19.75

And, cost of fabric with unit rate = $9.96

= $9.96 × 15/4 = $37.35

Total cost = $37.35 + $19.75 = $$57.1

Hence, the total cost of the fabric is $57.1
