The total cost of a Jacket is $124.75 and the cost of pair of sneaker is $74.75.
Let us say that the cost of the pair of sneakers is X dollars.
According to the given situation,
Cost of One jacket is 50 dollars more than the cost of a pair of sneakers.
Cost of one jacket = $(50 + X).
Total cost of one jacket and one pair of sneakers is $200.
Total cost of jacket and sneakers = $200
We get,
X + (X+50.5) = 200
2X + 50.5 = 200
The above equation that we have got is linear equation in one variable because it has degree 1 and one 1 variable.
Further solving the equation,
2X + 50.5 = 200
2X = 149.5
X = 74.75
So, the cost of one pair of sneakers is $74.75
Cost of One jacket is $(X + 50.5).
Cost of one jacket = $124.75.
So, one jacket costs $124.75 and sneakers cost $74.75.

Albert is taking a 60 item multiple choice test. He knows the correct answers to all,except 1/5 of the items.If he guesses correctly on 3/4 of these questions,how many items correctly?
57 items are correct.
What is an item?
Items are a fundamental component of an OracleAS Portal page. Item types are used to categorize items. Item types determine the contents of an item as well as the information kept about it. Users with the necessary permissions can add an item or create an item type. The properties of an object type define the information stored about it. The item types that you can add to a page differ depending on whatever item types the page group administrator has included in the page group. If the built-in item types are insufficiently flexible, users with proper access can develop new custom item kinds to fulfill their needs.
1/5 of 60 items = 60/5 = 12 items
3/4 of 12 items = 12x3/4 = 9 items
Total no. of correct items = 60 - 12 + 9 = 57 items

Use the point-slope formula to write an equation of the line that passes through (0,6) and (-2,0) write answer in slope intercept form
Equation using slope intercept form is 3y = x + 18
What is slope intercept form?An intercept in mathematics is a location on the y-axis through which the line's slope passes. It is a place on the y-axis where a straight line or a curve crosses. This is reflected in the equation for a line, which is written as y = mx + b, where m denotes slope and c denotes the y-intercept. Y = mx + b is the general formula for the slope-intercept form, where m stands for the line's slope and b for the y-value of the line's y-intercept. We may more easily determine a line's slope and its y-axis intersection using the slope-intercept form of a linear equation.
Given Data
Points(0,6) and (-2,0)
The slope formula = [tex]\frac{y_{2}-y_{1 } }{x_{2}-x_{1} }[/tex]
y₂= 0
y₁=6
x₂=-2
x₁=0
Slope = (-2-0)/(0-6)
Slope = -2/ -6
Slope = 1/3
Slope intercept form
y = mx + b
y = (1/3)x + 6
y = (x+18)/3
3y = x + 18

To determine if a function is even or odd, we start from its definition.
While for an EVEN FUNCTION we have: F(x) = F(-X), for an ODD FUNCTION we have F(-X) = -F(X)
Now, from this, we can check that all the values the function achiever for any X value, the -X has same height. The function presents a symmetry over the Y-axis, and this implies in a function to be an EVEN FUNCTION.
And from the solution developed above, the only statement that is true is the

Determine whether the point (4,2) is in the solution set of the system of inequalities below. 4x + y < 2, y > -2
The point (4,2) is not in the solution set as it do not satisfy the first inequality 4x+y<2.
To be in the solution set of the system of inequalities the point (4.2) must satisfy both the given linear inequalities.
So, 4x + y < 2
when x = 4, y = 2
4(4) + 2 = 18 which is not less than 2
So, point do not satisfies this linear inequality
Now, for y>-2,

The formula in getting the area of the circle is:
[tex]A=\pi r^2[/tex]where r = the radius of the circle and the value of π = 3.14
In the diagram, the radius of the circle is 4 mm. Let's replace the "r" in the formula with 4 mm and "π" with 3.14
[tex]A=(3.14)(4mm)^2[/tex]Then, simplify.
[tex]\begin{gathered} A=(3.14)(16mm^2) \\ A=50.24\text{ }mm^2 \end{gathered}[/tex]Therefore, the area of the circle is 50.24 mm². (Option D)
We have π = 3.14 and the radius is 4 mm. Therefore we apply the following formula:
A = π * r²Replacing values in the equation.
A = 3.14 * (4 mm)²We calculate potentiation.

The answer can come from any of the conditions stated above, so the solution is the OR combination of the individual solutions.
The first condition states:
x - 4 ≥ 0 AND x + 4 ≥ 0
This leads to the solution:
x ≥ 4 AND x ≥ -4
If x must be greater or equal to 4 and greater or equal to -4, then the AND combination gives the solution: x ≥ 4
The second condition states:
x - 4 ≤ 0 AND x + 4 ≤ 0
This leads to:
x ≤ 4 AND x ≤ -4
The AND combination gives the second solution x ≤ -4
The final solution is the first solution OR the second solution, that is:

Find all critical points of the function g(x)=sin^2(11x). Express your answer in terms of pi.
(Use symbolic notation and fractions where needed. Use n for all integer values.)
Critical points are the points where the slope of the function is zero thus at θ = 0,π/22,π11,3π/22 ... will be the critical points of function g(θ) = sin²(11θ).
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
As per the given function,g(θ) = sin²(11θ).
The critical points are the points where the slope of the tangent of the function is zero.
The slope of the tangent of a function is the first derivative thus,
g'(θ) = 0 ⇒ 2× 11 sin(11θ)cos(11θ) = 0
Sin(11θ) = 0 ⇒ θ = 0
Cos(11θ) = 0 ⇒ 11θ = π/2
θ = π/22
Since, sinusoidal functions are repeating thus,
Next critical point = π/22 + π/22 = π/11 and so on.
Hence "Critical points are the points where the slope of the function is zero thus at θ = 0,π/22,π11,3π/22 ... will be the critical points of function g(θ) = sin²(11θ)".

The space occupied by a plat surface is called Surface area.
Given that;
Surface area (S) = 2πr² + 2πrh
Where, r is the base radius and h is the height.
Now, When Surface area = 175 square inches
Radius (r) = 6 inches.
Then, We can calculate height as;
Since,
Surface area (S) = 2πr² + 2πrh
175 = 2 × 3.14 × (6)² + 2 × 3.14 × 6 h
175 = 226.08 + 37.68h
175 - 226.08 = 37.68 h
