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
Answers
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 width and area of the Rectangular tag is 10 centimeters and 40 centimeters square.
As per the question statement, The perimeter of a rectangular price tag is 28 centimeters. Its length is 4cm. We are supposed to find its width and area.
Let width be [tex]w[/tex]
Perimeter = [tex]2(length*width)[/tex]
[tex]28=2(4+w)\\w=14-4\\w=10cm[/tex]
Hence width is 10 cm
Now area of rectangle = [tex]length*width[/tex]
Area = [tex]4*10=40cm^{2}[/tex]
Hence area is 40 centimeter square.
Therefore the width and area of the Rectangular tag is 10 centimeters and 40 centimeters square.

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?
Answers
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.

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 mural in the art gallery is 7 meters tall. It's 69 centimeters taller than the marble sculpture. How tall is the sculpture?
Answers
Find the height of the marble sculpture if the mural is 69 centimeters taller.
Solution:
Convert the height of the mural into centimeters to easily calculate how tall it is from the marble sculpture.
1 meter = 100 cm
7 meters = 700 cm
Subtract 69 cm from 700 cm in order to get the height of the marble sculpture.
700cm - 69 cm = 631 cm
Convert 631 cm into meters by dividing it with 100.
=631 /100
= 6.31 m
The height of the mural is 6.31 m

P(x, y) = (2 / 7) * A(x, y) + (5 / 7) * B(x, y)
P(x, y) = (2 / 7) * (- 4, 2) + (5 / 7) * (3, - 6)

subtract ax from both sides

-2y=-16-3x
Subtract C from both sides
-2y=-3x+-16

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.the tricycle fare for the first kilometer costs = 15.00
additional amount = 6.50
Anthony paid to the tricycle driver = , 47.50
