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

A recipe that makes 8 cups of limeade uses 2 cups of lime juice.
Describe the related ratio 2:8 using ratio language. Does the ratio involve only parts, or does it involve a part and the whole?
Answer:
For every 2 cups of lime juice, the recipe makes 8 cups of limeade; a part and the whole.
Step-by-step explanation:
The ratio shows that for 2 cups of lime juice there needed proportion of 8 cups of limeade.
and, the ratio involve a part and the whole.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
A recipe that makes 8 cups of limeade uses 2 cups of lime juice.
and, ratio = 2:8

Use a product of two binomials to find a polynomial that represents the area of Roberto's plot.
Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2
. Rewrite the expression by using the Distributive Property: 8(5x - 4) *
Answer:

First, you multiply 8 time 5x which equals 40x. Next, you multiply 8 times 4 which equals 32, so it is 40x-32
Ethan uses the function f(x) = 2x2 + 2x + 4 to track the temperature of a substance over 8 hours. You know that f(3) = 28 meaning that the temperature of the substance is 28°C when you plug in a 3 for x. What is the domain of Ethan’s function?
The domain of the function f(x) = 2x² + 2x + 4 is (-∞, ∞).
What is Quadratic equation?The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of:
ax² + bx + c = 0
where x is the unknown variable and a, b and c are the constant terms.
You have the quadratic function
f(x) = 2x² + 2x + 4 ,
and remember that all quadratic functions are parabolas opening at point called the vertex.
Since you can plug any real number in our parabola here, its domain is all the real numbers, and this is true for all the quadratic functions of the form ax² + bx + c = 0.
Thus, in interval notation the domain of the function is (-∞, ∞).

At a sale, coats were sold for 52% of their original price. If the coats originally cost
$200 each, how much did a coat cost on sale?
Help me please
Answer:
Answer is 104
Step-by-step explanation:
The selling price of the coat is $104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price = $200
Selling price.
= 52% of $200
= 52/100 x 200
= $104
Thus,
$104 is the selling price of the coat.

Sunita creates a scale model of an aeroplane. The scale of the model is 4 cm to 15 m. Sunita's model has a wingspan of 17 cm. What is the wingspan of the real aeroplane?
Answer:
36.43m
Step-by-step explanation:
Let the wingspan of the real aeroplane = x
The scale of the model is 4 cm to 15 m.
= 4: 15 = 4/15.
Sunita's model has a wingspan of 17cm.
Hence:
4cm/15m = 17cm/xm
Cross Multiply
4x = 15 × 17
4x = 255
x = 255/4
x = 36.428571429 m
Approximately = 36.43 m
Therefore, the wingspan of the real aeroplane is 36.43m

3w+2=29(Multiply both sides by w)
3w2+2w=29w(Multiply both sides by w)
3w2+2w−29w=29w−29w(Subtract 29w from both sides)3w2−27w=0

An angle measures 160° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
The two angles are 10 degrees and 170 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
Let the angle be called "x", and the supplementary angle be called "180-x"
Converting words to math: x-160=180-x
Add x to both sides: 2x-160=180
Simplify: 2x=20
Divide by 2: x=10

How would you define slope?
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.
