To find the perimeter and area on a coordinate plane, first find each distance between points and then find perimeter and area with these lengths.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
Let's suppose if we have coordinates (a, b) (c, d), (e, f), and (g, h) on a coordinate plane.
We can use the distance formula to get the length of each side and then adding all the side lengths to get the perimeter of the figure, which is represented by the coordinates on a coordinate plane.
The distance formula can be used:
If we want the distance between (a, b) and (c, d)
[tex]\rm Distance = \sqrt{(c-a)^2+(d-b)^2}[/tex]
Similarly, we can find the distance for all the coordinates.
Let's assume the figure is a rectangle on a coordinate plane:
Then area = length×width
Thus, to find the perimeter and area on a coordinate plane, first find each distance between points and then find perimeter and area with these lengths.

Use the formula pH=log(1/[H^+]) to write an expression for the concentration of hydrogen ions in a liter of a sports drink that has a pH of 2.5.What is the concentration of hydrogen ions?
By using concepts of logarithms and powers, the concentration of hydrogen ions in a volume of a liter of a sports drink with a pH of 2.5.
How to solve a logarithmic formula
Logarithms are trascendental equations, that is, expression that cannot be described in terms of algebraic expressions. In this question we need to solve for the hydrogen ion concentration:
pH = log (1/[H⁺])
[tex]10^{pH} = \frac{1}{[H^{+}]}[/tex]
[tex][H^{+}] = 10^{-pH}[/tex]
[tex][H^{+}] = 10^{-2.5}[/tex]
[H⁺] ≈ 3.163 × 10⁻³

Answer:
4a) $26.5 because if x represents how many feet then the slope would be the price of one glulam beam.
4b) $63,600
Step-by-step explanation:
To find the answer to 4b we need to alter the equation we were given. Since x represents how many feet we buy we put 2400 in place of x.
y = 26.5 x 2,400
and we simply solve from here
y = 63,600
So, 63,600 is how much we would be spending for 2400 feet of beams. Hope this helps!!

Consider the following statistic. as of january 2009, the usa has produced 60,000 metric tons of nuclear waste in 60 years of operating 104 nuclear power plants. on average, how much waste is produced by each plant on a monthly basis? 0.8 tons per month 83.3 tons per month 104 tons per month 866.3 tons per month
Using proportions, it is found that the average waste produced by each plant on a monthly basis is of 0.8 tons per month.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there is a period of 60 x 12 = 720 months, with 104 plants, and 60,000 tons of waste were produced, hence the average is given by:
A = 60000/(720 x 104) = 0.8 tons per month.

1.Mary has ( 20xy - 10x²) sweets. She wants to divide the sweets equally among her (5x) friends.
if X=6 and Y=4, how many sweets:
how many friends does Mary have?
Answer:
Mary has 120 sweets and 30 friend.Step-by-step explanation:
if x = 6 and y = 4
then
20xy - 10x² = 20×(6)×(4)-10×(6^2) = 120
Therefore,
Mary has 120 sweets
……………………………………
if x = 6 and y = 4
then
5x = 5 × (6) = 30
…………………………
120 ÷ 30 = 4
Then 4 sweets per friend.

Answer:
D
Step-by-step explanation:
when x = 0, y = 40
therefore you can pick either A or D only.
while x increases, y decreases, that's negative relation
so, answer is D
Answer:
Option D
Step-by-step explanation:
y = mx + b
b is the y - intercept (when x = 0):
this graph doesn't show any negative values on the axis so options B and C can't be true since it they have - 40 when its positive 40
y = mx + 40
The dot association is going downwards, the y values are getting smaller
making this a negative association leaving on ly option d true

What is algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Pete is making decorations for a dinner party. The instructions tell him to use 9 flowers for a medium-sized decoration which has 2 lilies, 1 rose, 3 carnations, 2 daffodils and 1 iris.
The ratio of daffodils to total flower is,
n=2/9.
To make a large decoration, Pete uses 36 flowers. Let suppose the daffodils flower he needs for this is x. Thus,
x=36*(2/9)
x=4*2
x=8
The rose flower is increased from 1 to 2. Thus, the total number of flower also be twice for decoration.
Flower=2*9
Flower=18
Now Pete uses 10 lilies instead of 2 which is 5 times the medium-sized decoration. Thus, the carnations to be needed is,
Carnations=3*5
Carnations=15
Hence, the daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.

Which math sentence can be used to determine if this triangle is a right triangle? A triangle has side lengths 12, 15, 18. 12 + 15 = 18 12 squared + 15 squared = 18 squared 12 + 18 = 15 12 squared + 18 squared = 15 squared
Answer:
12^2 + 15^2 = 18^2
Step-by-step explanation:
If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle
a^2 + b^2 = c^2
12^2 + 15^2 = 18^2

29 + 32 + 35 + 38 + 41 + ... + 59
The sum of the finite arithmetic series of 26 + 29 + 32 + 35 + 38 + 41 + 44 is 245. Arithmetic series is a sequence of number such that the difference between any term and the previous term is a constant number. When we sum a finite number of terms in the arithmetic series, we get the finite arithmetic series.
