what is the measure of the length of a rectangle with a perimeter of 10 inches and a width of 2 inches?
Answer:
3 inches
Step-by-step explanation:
The perimeter is the sum of all the sides of a shape. A rectangle has 4 sides.
2 * 2 = 4
One side is 2 in., so the parallel side is also 2 in.
10 - 4 = 6
Subtract the sum from the perimeter.
6 / 2 = 3
Since there are two sides left, divide by 2.

Explain how to get the Unit Rate for Amount of Miles Ran per Minute for #18. Jaime ran 6 miles in 60 minutes. How far does Jaime run (in miles) per minute? Show all work and then write an explanation.
A mile is 5,280 feet long and an hour is 3,600 seconds long, thus 60 miles per hour is 60 x 5,280 / 3,600 = 88 feet per second.
What is the unit rate formula?How Do I Determine the Unit Rate? The denominator of a unit rate is always 1. To calculate the unit rate, divide the denominator by the numerator so that the denominator equals 1. For example, if 50 kilometers are reached in 5.5 hours, the unit rate is 50 kilometers/5.5 hours = 9.09 kilometers per hour.
Miles per hour is a relatively typical example of a unit rate that we face on a daily basis. This rate is a unit rate since it describes the number of miles in one hour.

Show that the quadrilateral with the given vertices is a trapezoid. Then decide whether it is isosceles.
The quadrilateral MNPQ is trapezoid but not an isosceles trapezoid .
What is a trapezoid?A trapezoid, as well known as a trapezium, is a closed, flat shape with four straight sides and one pair of parallel sides.
Here given points,
M(-2,0), N(0,4), P(5,4), and Q(8,0) are given.
We are familiar with the slope formula,
Slope = y2 - y1 / x2 - x1
So here,
Slope of MN = 4 - 0 / 0 - (-2)
= 4/2
= 2
Slope of NP = 4 - 4 / 5 - 0
= 0/5
= 0
Slope of PQ = 0 - 4 / 8 - 5
= -4/3
Slope of QM = 0 - 0 / -2 -(-8)
= 0/10
= 0
Therefore we can see, NP||QM and MN∦PQ.
Therefore MNPQ is a trapezoid because it has two parallel sides.
By using distance formula,
MN = [tex]\sqrt{0-(-2)^{2} +(4-0)^{2} }[/tex]
= √20
= 2√5 units
PQ = [tex]\sqrt{(8-5)^{2} +(0-4)^{2} }[/tex]
= √25
= 5 units
Here MN ≠ PQ , MN and PQ are not congruent to each other.
Therefore MNPQ not is a isosceles trapezoid.

The power (or exponent) of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example the little "2" says to use 8 two times in a multiplication: 82 = 8 × 8 = 64.
What are powers?
A power is the product of multiplying a number by itself. Usually, a power is represented with a base number and an exponent. The base number tells what number is being multiplied. The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied.
Since 2376÷10
It will give us

Which description best compares the graphs of the two functions below?
A description which best compares the graphs of the two functions above include the following: B. The line for function A is steeper.
How to compare the two functions?In order to compare the two functions, we would have to find the slope of function B based on the data points contained in the table by using the slope formula.
Mathematically, the slope of a straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Substituting the given points into the slope formula, we have the following;
Slope, m = (-1 - (-2))/(3 - 0)
Slope, m = (-1 + 2)/3
Slope, m =1/3
From function A y = 3x - 2, the slope is equal to 3. Consequently, we can logically deduce that the line representing function A is steeper than the line representing function B because its slope is bigger i.e 3 > 1/3.

What is an exponential function called?
An exponential function is a function in which the variable appears in an exponent.
The most common form of an exponential function is f(x) = aˣ, where a is a positive constant, known as the base of the function, and x is the variable. The variable x is called the exponent of the function.
The base, a, determines the growth rate of the function. If the base is greater than 1, the function will increase rapidly as x increases. If the base is between 0 and 1, the function will decrease rapidly as x increases.
Exponential functions can also be written in the form y = a×bˣ, where a and b are constants, b is the base and x is the exponent. In this form, a represents the y-intercept of the function, which is the point where the function crosses the y-axis.
An exponential function can be recognize by the presence of the variable in an exponent and the graph of an exponential function is a curve that goes up and to the right if the base is greater than 1, and goes down and to the right if the base is between 0 and 1.
In conclusion, an exponential function is a function in which the variable appears in an exponent and is defined as f(x) = aˣ or y = a×bˣ, where a is the base of the function and x is the exponent.
The base determines the growth rate of the function and the graph of an exponential function is a curve that goes up and to the right if the base is greater than 1, and goes down and to the right if the base is between 0 and 1.

Is it possible to construct a triangle whose sides are 3.5 cm 9.2 cm and 5.3 cm Why or why not?
We cannot construct a triangle with side lengths 3.5 cm, 9.2 cm and 5.3 cm. So it is not possible to construct a triangle whose sides are 3.5 cm 9.2 cm and 5.3 cm. This is because these lengths does not follow triangle inequality theorem.
It is not possible to construct a triangle using the given side lengths of 3.5 cm, 9.2 cm, and 5.3 cm. This is because of the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, if we take 3.5 cm and 5.3 cm as two sides, the sum of their lengths is 8.8 cm. But the length of the third side (9.2 cm) is greater than 8.8 cm, so these three side lengths cannot form a triangle.
It is important to note that this theorem applies to any triangle, whether it is acute, right or obtuse-angled triangle.

How do you convert base 10 to base E?
To convert from base 10 to base e, we need to split down a number in base e into the powers of e.
When we convert from base 10 to base e, the pattern will be exactly the same. It will be just with e instead of 10.
For example, to see how many digits (before the decimal point) of ln(12) = 2.4849...
It means that the first digit will be on the e^2 position. Now lets find:
12 / e^2 = 1.624…
So, there will only be a 1 in the e^2 position. The remaining is 12 – e^2. The next position is e^1 position. To find out what’s on this position, we need to do the following calculation:
(12 – e^2) / e = 1.696…
The next digit will also be a 1.
Now we do the 1’s position:
(12 – e^2 – e) / 1 = 1.892…
Next digit’s a 1.
We can continue for a few more decimal places:
(12 – e^2 – e – 1) / e – 1 = 2.426…
Next digit’s a 2.
(12 – e^2 – e – 1 – 2 * e – 1) / e – 2 = 1.159…
Next’s digit a 1.
So, 12 in base e is 111.21…
