Step-by-step explanation:
1 is the number in which its reciprocal is its own because 1 has both the same numerator and denominator which means the reciprocal is the same. For example, 1/1 is equal to 1 and the reciprocal of 1/1 is 1/1
2/2 is equal to 1 and the reciprocal of 2/2 is 2/2
This can keep going on and on.

Answer if you know your right, bur don't answer just for the points
Answer:
42% is less than 5/8
Step-by-step explanation:
If 42% is converted to a fraction, it comes out to 21/50, which is smaller than 5/8. You could also convert 5/8 into a percentage, which comes out to 62.5%. :)
Answer:
42% < 5/8
Step-by-step explanation:
We're going to change 5/8 to a percent. All you have to do is 5/8, which is 0.625. If you want to convert a decimal to a fraction, you move the decimal 2 places to the right, which is 62.5. Therefore, 42% is less, or < than 5/8.

5. The 50 snakes in the serpentarium include families of 10 vipers, 23 colubrids, 9 elapids, and 8 giant snakes.
Calculate the percent of each type of snake. Use the percent that you find and multiply each times 360° to
find the number of degrees for each sector.
I need help solving the percent and degree
Percent of vipers is 20% and its degree is 72 degrees.
Percent of colubrids is 46% and its degree is 165.60 degrees.
Percent of elapids is 18% and its degree is 64.80 degrees.
Percent of giant snakes is 16% and its degree is 57.60 degrees.
How we do calculate the percent and degree?The percent can be calculated as follows:
Percent of vipers = (Number of vipers / Total number of snakes) * 100 = (10 / 50) * 100 = 0.20 * 100 = 20%
Percent of colubrids = (Number of colubrids / Total number of snakes) * 100 = (23 / 50) * 100 = 0.46 * 100 = 46%
Percent of elapids = (Number of elapids / Total number of snakes) * 100 = (9 / 50) * 100 = 0.18 * 100 = 18%
Percent of giant snakes = (Number of giant snakes / Total number of snakes) * 100 = (8 / 50) * 100 = 0.16 * 100 = 16%
The degrees can be calculated as follows:
Degree of vipers = Percent of vipers * 360 = 20% * 360 = 72 degree
Degree of colubrids = Percent of colubrids * 360 = 46% * 360 = 165.60 degree
Degree of elapids = Percent of elapids* 360 = 18% * 360 = 64.80 degree
Degree of giant snakes = Percent of giant snakes * 360 = 16% * 360 = 57.60 degree

The coordinates of the point P is P(x, y) = (1, - 26 / 7). (Correct choice: C)
How to calculate a resultant point's coordinates using the weighted averages method?
We must locate the third point by applying a method based on a weight average-like formula after finding the coordinates of two points on the Cartesian plane:
P(x, y) = (2 / 7) * A(x, y) + (5 / 7) * B(x, y)
P(x, y) = (2 / 7) * (- 4, 2) + (5 / 7) * (3, - 6)
P(x, y) = (- 8 / 7, 4 / 7) + (15 / 7, - 30 / 7)
P(x, y) = ( 7 / 7, - 26 / 7)
P(x, y) = ( 1, - 26 / 7)

Start with the graph of the absolute value function. Stretch it by a factor of 3 and shift 2 units up.
The absolute value function of the given expression is g(x) = 3*Ix + 2I.
What is the role of absolute value?The absolute value function is often assumed to provide the number's distance from zero on a number line. Algebraically, the output is really the value without respect to sign regardless of what the input value is.
According to the given data:Let's define transformations in broad strokes.
A vertical stretch with scale factor A is denoted by:
g(x) = A*f(x)
A vertical shift in A units is denoted by:
g(x) = f(x) + A
If A is positive, the shift is positive; if A is negative, the shift is negative.
A horizontal shift in A units is denoted by:
g(x) = f(x - A)
If A is greater than zero, the shift is toward the right.
The shift to the left if A is negative.
Then we begin with the maximum value parental function f(x) = IxI.
"The graph of both the absolute value parent function has been stretched vertically by a factor of three."
we can start with:
g(x) = 3*f(x)
"then shifted two units left"
g(x) = 3*f(x - (-2))
and since f(x) = IxI, they have:
g(x) = 3*Ix + 2I
the absolute value function of the given expression is g(x) = 3*Ix + 2I.

A dish containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10^-16 How many times larger is the diameter of the dish than the diameter of the bacterium
For a dish that is containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10^-16, the number of times that the diameter would be larger is 10¹² times.
How to solve for the diameterWe have the diameter of the dish to be 0.0001
This is the same as 10⁻⁴
The bacterium has the diameter at 10^-16
The difference between the diameter of the dish than the bacterium would be solved by
1 x 10⁻⁴ / 10^-16
= 10¹²
Hence we would have to say that for a dish that is containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10^-16, the number of times that the diameter would be larger is 10¹² times.

Answer:
C. 1889
Step-by-step explanation:
Given fixed weekly costs of $3778 and a variable cost per handle of $1, you want to know how many handles must be produced weekly for sale at $3 each to break even.
Contribution marginThe "contribution margin" of each handle is the difference between its variable cost and its selling price:
$3 -1 = $2
Break evenThe enterprise will break even when the sum of contribution margins is equal to the fixed costs. If h is the number of handles produced and sold, then to break even, we must have ...
2h = 3778
h = 1889
1889 handles must be molded weekly to break even.
__
Additional comment
You get the same result if you write the profit equation and solve for the number of handles that makes profit be zero.
profit = revenue -cost
0 = (3h) -(3778 +1h)
3778 = 2h . . . . . as above
1889 = h

The value of the n in the mean value is 1.
According to the statement
We have to find that the value of the n in the mean.
So, For this purpose, we know that the
Mean is the simple mathematical average of a set of two or more numbers.
From the given information:
The mean number of hours is 1.75
Then
We are given that
Day Hours
Sunday 0

Wednesday 2.5
Thursday 3
Friday 0
Saturday n
Mean number of hours of study per day=1.5
Then
Total number of days=7
Using the formula:
Mean = sum of data / Total number of the data points
1.5 = 9.5+n / 7
1.5*7 = 9.5+n
10.5 = 9.5+n
n = 10.5 - 9.5

Answer:
300 children and 400 adults
Step-by-step explanation:
14(x) + 38(700-x) = 19,400
14x + 26,600 - 38x = 19,400
14x - 38x = -7,200

Under her cell phone plan, Fatoumata pays a flat cost of $59 per month and $3 per
gigabyte. She wants to keep her bill under $75 per month. Which inequality can be
used to determine x, the maximum number of gigabytes Fatoumata can use while
staying within her budget?
Answer:
[tex]59 + 3x < 75[/tex]
Step-by-step explanation:
We know from the question that Fatoumata pays a flat cost of $59 per month and $3 per gigabyte.
If we consider [tex]x[/tex] to be the number of gigabytes she uses in a month, then her bill every month can be represented by the following expression:
[tex]59 + 3x[/tex] .
We are told that the bill has to be kept under $75. Therefore:
[tex]59 + 3x < 75[/tex]
This inequality can be used to solve for [tex]x[/tex], and so we can use it to find the maximum number of gigabytes she can use while keeping the bill under $75.
The inequality for the maximum number of gigabytes Fatoumata can use while staying within her budget will be equal to $59 + $3(x) < $75.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given information in the question,
Price of cell phone plan per month = $59
The price per gigabyte = $3
Then, the equation as per the statement will be,
$59 + $3(x)
Here, x is the number of gigabytes used in a month.
So, the inequality will be,
