The unit rate of the silver chain is $0.44 per inch.

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: 16 inches of silver chain costs $36 and 18 inches cost $40.50

Thus we have the unit rate( dollar/inch) =36/16=40.50/18=4/9

Therefore the unit rate is given by 4/9 or 0.444 dollar per inch.

Hence, The unit rate of the silver chain is $0.44 per inch.

Answer:

n = 36

Step-by-step explanation:

4 : 5 = n : 45

It can be also written as :-

[tex]\frac{4}{5} = \frac{n}{45}[/tex]

Multiplying both the sides by 45 ,

[tex]=> \frac{4}{5} \times 45 = \frac{n}{45} \times 45[/tex]

[tex]=> n = 4 \times 9 = 36[/tex]

Answer:

The answer is 113.0 ft^2

Step-by-step explanation:

To find the area you do pi times the radius squared, so that would be pi times 36. which equals 113.0 ft^2.

The area of a given circle is 113.0 square feet. Therefore, option A is the correct answer.

The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.

Given that, the diameter of circle is 12 feet.

Here, radius = 12/2

= 6 feet

Now, area of a circle = 3.14×6²

= 3.14×36

= 113.0 square feet

Therefore, option A is the correct answer.

Answer:

√35i

Step-by-step explanation:

i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.

Answer:

We know that √-1 = i, where "i" is the imaginary unit

± √(-35) = ± √(35) i

Answer: 250 yd

Step-by-step explanation:

From the question, we are informed that the scale model of the statue of liberty is 8 inches tall and that the scale used is 1 in = 30yd.

Since the scale used was 1 in = 30 yd, the actual height of the statue of liberty will be:

= 8 × 30

= 240 yd

Answer:

1109

Step-by-step explanation:

an = d (n - 1) + c

an = what you're looking for

n = term position

d = the common difference, in your case, 16

c = first term of the sequence, or -27

a₇₂ = 16(72 - 1) + -27 = 1109

Answer:

The slope of the line on the graph is [tex]\frac{3}{2}[/tex].

Step-by-step explanation:

The slope of a line can be found with [tex]\frac{\Delta y}{\Delta x}[/tex]. The points (3,2) and (-1,-4) lie on the line, so we can subtitute [tex]\Delta y = -4 -2 = -6[/tex] and [tex]\Delta x = -1-3 = -4[/tex] to see that the slope equals [tex]\frac{-6}{-4} = \frac{3}{2}[/tex]. This answer makes sense because the slope is going up when [tex]x[/tex] becomes larger (the slope is positive), and we travel more in the [tex]y[/tex]-direction than in the [tex]x[/tex]-direction (the slope is greater than 1).
