What are the 2 right angle measures? * 40 and 120 120 and 60 180 and 120 140 and 40
The two right angle measure is 120° and 60° and 140° and 40° .
In mathematics and trigonometry, a right angle is a quarter-turn or an angle that is exactly 90 degrees or π/2 radians . If a ray is positioned so that its terminal is in a line and they are equal, the adjacent angles represent right angles.
Orthogonality, which refers to the property of producing right angles, and perpendicular lines, which are defined as lines that intersect at right angles, are important and closely related geometrical concepts.
The existence of a feature resembling a right angle, which distinguishes right triangles, makes all right angles a fundamental notion in trigonometry.
We know that a right angle is equal to 90° .
Hence 2 right angles = 90° × 2 = 180°
Now we will use the options to check if they add up to 2 right angles or 180°
120° + 60° = 180°
140° + 40° = 180°
Therefore they are he required options that satisfy the given condition.

What are linear equations?Linear equations are equations that have constant average rates of change.
How to determine the equation of the line?The given parameters are
Points (x, y) = (1, 7) and (2, 10)
Start by calculating the slope of the line using
Slope = (y₂ - y₁)/(x₂ - x₁)

The Kwanzan cherry sapling planted amounted to twice the number of magnolia. Is 35 saplings were planned in all, how many Kwanzan cherry sapling he planted?
16 number of Kwanzan cherry saplings he planted.
Let the gardener plant the no of Crab apple saplings was x
Since the no of magnolia in saplings he planted was 3 less than crab apple saplings.
Therefore, the no. of magnolia Saplings planted was x-3
Also, the Kwanzan Cherry sapling planted amounted to twice the number of magnolia.
Therefore, the Kwanzan Cherry sapling was. planted by him 2(x-3)
Conditionally,

Given -86=4+5(3x-3), what is the value of 3/5x ? Help meeee
To solve for the value of 3/5x, we can start by distributing.
-86 = 4 + 5(3x - 3) → -86 = 4 + 15x - 15
-86 = 15x - 11
Add 11 to both sides-86 = 15x - 11 → -75 = 15x
Divide both sides by the coefficient
-75 = 15x → -5 = x
Therefore, x = -5.
Plugging in -5 for x
To find the value of 3/5x, we can plug in -5 for x.
3/5(-5) = -3
Hence, the value of 3/5x is -3.
In an effort to cut costs and improve profits, many US companies have been turning to outsourcing. In fact, according to Purchasing magazine, 54% of companies surveyed outsourced some part of their manufacturing process in the past two to three years. Suppose 555 of these companies are contacted. What is the probability (as a decimal) that 48% or less of these companies outsourced some part of their manufacturing process in the past two or three years? Round to 4 decimal places
0.23% probability that 48% or less of these companies outsourced some part of their manufacturing process in the past two or three years.
What is Central Limit Theorem ?
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean μ and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean μ and standard deviation s.
The central limit theorem will be used to find the probability (as a decimal) that 48% or less of these companies outsourced some part of their manufacturing process in the past two or three years.
Now we use the sampling distribution of the sample proportions, which have:
μ = p = 0.54
s = √{(p(1-p)/n)}
s = √{(0.54x0.46)/555)}
s = 0.0212
The probability is the p-value of Z when X = 0.48. So
Z = (X- μ)/σ
By the Central Limit Theorem
Z = (X- μ)/s
Z = (0.48-0.54)/ 0.0212
Z = -2.84, has a p-value of 0.0023.
0.0023 x 100% = 0.23%
This, 0.23% probability that 48% or less of these companies outsourced some part of their manufacturing process in the past two or three years.

The rate of change between a and b is -5, and between x and x + h is also -5.
How to find the rates of change?
For a function f(x) the formula for the rate of change on an interval [a, b] is:
( f(b) - f(a))/(b - a)
so if the function is f(x) = -5x - 8, the average rate of change will be:
( -5b - 8 + 5b + 8)/(b - a) = 5*(a - b)/(b - a) = -5
c) Now we want to use the interval [x, x + h], we will get:
( -5*(x + h) - 8 + 5*x + 8)/(x + h - x)
= (-5h)/h = -5
Again, the rate is -5

A relative maximum point is a point where the function changes direction from increasing to decreasing (making that point a "peak" in the graph). Similarly, a relative minimum point is a point where the function changes direction from decreasing to increasing (making that point a "bottom" in the graph).
An absolute maximum point is a point where the function obtains its greatest possible value. Similarly, an absolute minimum point is a point where the function obtains its least possible value.
Our function starts increasing, and approximately at x = 2, it starts decreasing, which means this is a relative maximum point, and this is also the greatest possible value for our function, therefore, this is also an absolute maximum. There are no further critical points.

The function g(c)=75-3.5c represents the amount of money remaining on a gift card after purchasing c number of ice cream cones how much does an ice cream cone cost
The price of an ice cream, as calculated with the help of given function is 3.5
What is function in mathematics?
A function is a relationship between a set of inputs and a set of permitted outputs, and it has the property that every input is connected with exactly one output. If every element in set A has one end and only one image in set B, then the mapping from set A to set B is merely a function. Choose any two non-empty sets for A & B.
In order to get price of 1 ice cream, we will first calculate the amount left after purchasing 2 ice creams and the amount left after purchasing 1 ice cream with the help of given function. then we will do subtraction to get the answer.
The amount left after purchasing 2 ice creams:
given function is: g(c)=75-3.5c
putting c = 2
g(2) = 75 - 3.5(2)
g(2) = 68
So, the amount left after purchasing 2 ice creams.
The amount left after purchasing 1 ice cream1:
given function is: g(c)=75-3.5c
putting c = 1
g(2) = 75 - 3.5(1)
g(2) = 71.5
So, the amount left after purchasing 1 ice cream.
Subtracting the amount left after purchasing 2 ice cream from the amount left after purchasing 1 ice cream.
71.5 - 68
= 3.5
Hence, the price of an ice cream is 3.5.
