At the local store, the cost of 1 pair of jeans is $24 and the cost of 3 pairs is $24 × 3 = $72. At the online store, the cost of 2 pairs of jeans is ($22 × 2) + $6 = $50 and the cost of 3 pairs is ($22 × 3) + $6 = $72.
Complete question :
Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and
ignore any taxes.
Answer:
$24, $72
$50
Step-by-step explanation:
From the table :
At local store :
2 pair of jeans cost $48
Cost of a pair :
Cost of 2 pairs / number of pairs
$48 / 2 = $24
Cost of 3 pairs :
Cost per pair * number of pairs :
$24 * 3 = $72
At online store :
Cost of Jean include a fixed fee of $6
Cost of one pair of Jean = $28
Actual cost of Jean :
$28 - $6 = $22
Hence, cost of 2 pair of jeans:
($22*2) + $6
$44 + $6 = $50

Set up an equation and solve for x :⋆ [tex] \large{ \bf{(4x + 9) \degree = 2x \degree + (3x - 12) \degree}} [/tex] [ Exterior angle is always equal to the sum of two non - adjacent interior angles ]

~Add the like terms : 2x ° & 3x°
⟶ [tex] \large{ \bf{4x \degree + 9 \degree = 5x \degree - 12 \degree}}[/tex]
~Move 4x to right hand side and change it's sign
~Similarly move 12 to left hand side and change it's sign
⟶ [tex] \large{ \bf{9 \degree + 12 \degree = 5x \degree - 4x \degree}}[/tex]

A shipping container will be used to transport several 140-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 26000
kilograms. Other shipments weighing 13200 kilograms have already been loaded into
the container. Which inequality can be used to determine c, the greatest number of
140-kilogram crates that can be loaded onto the shipping container?
Answer:
91.42 crates
Step-by-step explanation:
Let
Greatest Number of 140kg crates = x
weight of crate = 140-kilogram
Weight of other shipment = 13200 kilograms
greatest weight of container = 26000 kilograms
Weight of other shipment + (weight of crate * number of crates) ≤ greatest weight of container
13,200 + 140x ≤ 26,000
140x ≤ 26,000 - 13,200
140x ≤ 12,800
x ≤ 12,800/140
x ≤ 91.42 kilograms
Greatest Number of 140kg crates = 91.42 crates
if f(x) = 2x -3 what is the value of f(x) when x is -5?
Answer:
-13
Step-by-step explanation:
To find the value of f(x) when x is -5, substitute -5 for the x in the equation. Then, simplify:
[tex]f(x) = 2x-3\\\\f(-5) = 2(-5)-3\\f(-5) = -10-3\\f(-5) = -13[/tex]
So, when x is -5, the value of f(x) will be -13.

The tires on a mining truck are 14 ft tall. Which measurement is it (diameter, radius, or circumference)
Answer:
this is quite easy. if the tire is 14 ft. tall, that would mean the diameter is 14 ft. as well (do to a tire being round). the radius is half of the diameter, meaning the radius is 7 ft. finally, to find the circumference, you would have to multiply pi by 2 (6.28) then multiply this by the radius to make 43.98 ft.
Step-by-step explanation:
D = 14
R = 14/2 = 7
C = 2(pi) x 7 = 6.28 x 7 = 43.98

21.98 feet, what is the diameter of
the circle?
Use 3.14 for pi
Answer:
diameter = 7 feet
Step-by-step explanation:
Circumference of the circle = pi x d
21.98 = 3.14 x d
d = 21.98/3.14
d = 7 feet

12. Which of the following is another way to
classify a scalene triangle with one angle
greater than 90°?
A- acute
B - obtuse
C - right
D equilateral
Answer:
The correct answer would be obtuse
Step-by-step explanation:
An obtuse angle is an angle that has a measure of more than 90°
So if a triangle has an angle greater than 90° it would be classified as an obtuse triangle

Answer:
41

Erase the line in the middle and it's a right angle, which is 90 degrees, therefore if you subtract 49 from 90 you get 41, the missing angle.
a manufacturer is designing a flashlight for the flashlight to admit a focused beam the bull needs to be on the central axis of the parabolic reflector 33 cm from the vertex write an equation that models the parabola formed when a cross section is taken through the reflector Center access assume that the vertex of the parabola is at the origin of the XY coordinate plane in the parabola can open it any direction
Answer:
y= 1/12(x-0)^2+0
this answer works as an upward parabola
Step-by-step explanation:
The formula for a veritcal parabola is y=1/4p(x-h)^2+k(h,k)= coordinates of the vertex of the parabolap= absolute value of the distance from the vertex to the focus/directrixIn this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex. Now, you know the values of the variables. Fill in the valuesFROM THE FORMULA: 1/4p turns into 1/12 since p is 3.(x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0once all the variables are given values (except x and y) you have made your equation! The answer is y=1/12(x-0)^2+0MARK BRAINLIEST! this took forever, and I know this is the right answer since I got a perfect grade when I turned mine in.
The equation of a parabola and the coordinates of the focus can be
expressed in terms of the coordinate of the vertex and the coefficient of
the quadratic term
The equation that models the parabola formed by taking a cross section
through the Center of the flashlight with focus 33 cm from the vertex is [tex]y \ \mathbf{ = \dfrac{x^2}{132} }[/tex]
The process by which the above equation is arrived at is as follows;
The given parameters of the parabolic reflector are;
The focus of the parabolic cross section of the reflector = 33 cm from the
vertex, along the central axis
The location of the vertex of the parabolic cross section = The origin of the XY coordinate plane = (0, 0)
The vertex form of the equation of a parabola is y = a·(x - h)² + k
Where;
(h, k) = The coordinate of the vertex of the parabola
The coordinate of the focus, f = (h, k + 1/(4·a))
In the given parabola, the vertex (h, k) = (0, 0)
Therefore;
h = 0, and k = 0
The vertex of a parabola is along the central axis, therefore, the equation
of the central axis is the vertical line, x = 0
The x-coordinate of the focus, is therefore, x = 0
From which from the distance of the focus from the vertex = The y-coordinate = 33
The coordinate of the focus is (0, 33)
Equating the above coordinate to the general form of the coordinate of a parabola (opening up or down), gives;
Coordinate of the focus, f = (h, k + 1/(4·a)) = (0, 33)
Therefore;
As above, h = 0
k + 1/(4·a) = 33
From k = 0 obtained above, we get;
0 + 1/(4·a) = 33
a = 1/(4 × 33) = 1/132
a = 1/132
The equation of the parabola is therefore found by plugging in the values
of a, h, and k in the equation, y = a·(x - h)² + k, as follows;
[tex]y = \dfrac{1}{132} \times \left(x - 0\right )^2 + 0 \ \mathbf{ = \dfrac{x^2}{132} }[/tex]
[tex]\therefore \mathbf{The \ equation \ of \ the \ parabola \ is \ y} \mathbf{ = \dfrac{x^2}{132} }[/tex]
