Answer:
Length of window = 9 inch
Width of window = 7 inch
Step-by-step explanation:
Given;
Area of window and frame = 195 inch²
Frame width = 3 inch
Length of window = x + 2
Width of window = x
Find:
Value of x
Computation:
Length of window and frame = x + 2 + 3 + 3
Length of window and frame = x + 8
Width of window and frame = x + 3 + 3
Width of window and frame = x + 6
Area of window and frame = (l)(b)
(x + 8)(x + 6) = 195
x² + 6x + 8x + (8)(6) = 195
x² + 14x + 48 = 195
x² + 14x - 147 = 0
x² + 21x - 7x - 147 = 0
x(x + 21) - 7(x + 21) = 0
So,
x + 21 = 0 and x - 7 = 0
So,
X = 7
Value of x = 7
Length of window = 9 inch
Width of window = 7 inch

Wednesday - 9 hr 30 mins
Friday - 7 hr
Saturay - 5 hr 30 mins
---------------------------------------------------------------
If you earn $12.40 per hour, first you must find how many hours you worked total - in this case, 29 hr and 30 mins.
So you would be making $359.60 per week.
In ΔEFG, the measure of ∠G=90°, GF = 48, EG = 55, and FE = 73. What ratio represents the cosecant of ∠F?
Answer:
Cosec <F = 73/55
Step-by-step explanation:
In ΔEFG, the measure of ∠G=90°, GF = 48, EG = 55, and FE = 73. What ratio represents the cosecant of ∠F?
First you must know that;
Cosecant <F = 1/sin<F
Given
∠G=90°, GF = 48, EG = 55, and FE = 73.
ED ,= hyp = 73
EG = opp = 55*side facing <F
Using DOH CAH TOA
Sin theta = opp/hyp
Sin <F= 55/73
Reciprocate both sides
1/sinF = 73/55
Cosec <F = 73/55

Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0).
Plot triangles PQR and P'Q'R' on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R'? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer. (2 points)
Answer:
Triangle P' Q' R' is half the size of the original triangle.
-The scale factor is probably 1/3.
Part B: P'(1, −2), Q'(0, 3), and R'(−1, 0).
Part C: No, the triangles are not congruent. If the second triangle didn't have a dilation, and instead have a reflection of the first triangle, then it would be congruent.

6. Markets with elastic supply and demand curves: a) Have demand and supply curves that never intersect. B) Are very sensitive to a change in price. C) Have greater movements in quantity than prices. D) Are very sensitive to a change in quantity. E) Are only theoretical and do not exist in the real world.
Answer:
The correct statement is B (are very sensitive to change in price)
Step-by-step explanation:
Option B is correct because of the following reason -:
The degree to which a rise in price affects the quantity demanded or supplied is known as elasticity. In the case of elastic demand and supply, as the price rises, the quantity demanded falls and the quantity supplied rises more than proportionally. Inelastic price elasticity of demand and supply, on the other hand, induces a less than proportional change in quantity as prices change.
Hence , the correct option is B .

a cylinder has a volume of 500cm³ and a diameter of 18cm. which of the following is the closest to the height of the cylinder
Step-by-step explanation:
Volume of Cylinder =
[tex]500 {cm}^{3} = \pi {r}^{2} h[/tex]
given d = 18
r = 1/2 x d = 9cm,
[tex]\pi( {9}^{2} )h = 500 \\ 81\pi \: h = 500 \\ h = \frac{500}{81\pi} cm[/tex]
I will leave the answer in terms of Pi as I am not sure how you want to leave your answer as.
A circular opening of an ice cream cone has a diameter of 23 centimeters. The height of the cone is 17 centimeters, what is the
volume of the cone?
round to hundredth decimals if necessary.
Answer:[tex]2355.31\ cm^3[/tex]
Step-by-step explanation:
Given
diameter of the cone is [tex]d=23\ cm\quad [r=\frac{d}{2}=11.5\ cm][/tex]
The height of the cone is [tex]h=17\ cm[/tex]
The volume of a cone is [tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Insert the values
[tex]\Rightarrow V=\dfrac{1}{3}\times \dfrac{22}{7}\times 11.5^2\times 17=2355.309\\\\\Rightarrow V\approx 2355.31\ cm^3[/tex]
Thus, the volume of the cone is [tex]2355.31\ cm^3[/tex]

Given m
n, find the value of x and y.
(37-18)
(8x+12)
m
(2X+18)
n
Answer:
Step-by-step explanation:
The two inside angles will sum to 180°.
The top to angles are equal.
Think about this as what if both of the parallel lines were intersected by a perpendicuar line. Every angle would be a right triangle 90°. The inside angles will sum to 180° and the opposite angles are again equal.
(2x + 18) + (8x + 12) = 180
10x + 30 = 180
10x = 150
x = 15
-------------------------
(3y - 18) = (8x + 12) x = 15
(3y - 18) = (8(15) + 12)
(3y - 18) = (120 + 12)
(3y - 18) = 132
3y = 132 + 18
3y = 150
y = 50

Slice of a cake
Answer:
The correct answer in each case is:
Surface area = 60 [tex]cm^{2}[/tex]Surface area = 6000 [tex]mm^{2}[/tex]Surface area = 0.006 [tex]m^{2}[/tex] Volume = 1200 [tex]cm^{3}[/tex]Step-by-step explanation:
First, to calculate the surface area or the volume you must have all the measures in the same units, for the exercise we're gonna use centimeters and after we can replace the units in the answer if we need, then:
300 mm = 30 cm 40 cm 50 cm 2 dm = 20 cmNow, to obtain the surface area of the triangle we're gonna use the next formula:
Surface area = (base * height) / 2And we replace the values in centimeters:
Surface area = (30 cm * 40 cm) / 2Surface area = (120 [tex]cm^{2}[/tex]) / 2Surface area = 60 [tex]cm^{2}[/tex]To obtain this same value now in square milimeters, you must know:
1 [tex]cm^{2}[/tex] = 100 [tex]mm^{2}[/tex]Now, you must multiply:
60 [tex]cm^{2}[/tex] * 100 = 6000 [tex]mm^{2}[/tex]60 [tex]cm^{2}[/tex] = 6000 [tex]mm^{2}[/tex]To obtain this value now in [tex]m^{2}[/tex], you must know:
1 [tex]m^{2}[/tex] = 10000 [tex]cm^{2}[/tex]You must divide:
60 [tex]cm^{2}[/tex] / 10000 = 0.006 60 [tex]cm^{2}[/tex] = 0.006 [tex]m^{2}[/tex]By last, to obtain the volume of the piece of cake, you can use the next formula:
Volume of the piece of cake: surface area * depthAnd we replace the surface area in [tex]cm^{2}[/tex] because the answer must be in [tex]cm^{3}[/tex]:
Volume of the piece of cake: 60 [tex]cm^{2}[/tex] * 20 cmVolume of the piece of cake: 1200 [tex]cm^{3}[/tex]I need this done, please I need to pass these six weeks! Thanks

The height of a cone is twice the radius of its base.
What expression represents the volume of the cone, in
cubic units?
23x3
49X3
Answer:
2/3πx³
Step-by-step explanation:
Volume of a cone is expressed as;
V = 1/3πx²h ... 1
x is the radius
h is the height of the cone
If the height of a cone is twice the radius of its base, then;
h = 2x ... 2
Substitute equation 2 into 1
Recall that V = 1/3πx²h
V = 1/3πx²(2x)
V = 2/3πx³
Hence the expression that represents the volume of the cone is 2/3πx³ cubic units

Step-by-step explanation:
An equation for a quartic function with zeros 4, 5, and 6 that passes through
the point (7, 18) is
Answer:
One example of this can be:
P(x) = (3/2)*(x - 4)*(x - 5)*(x - 5)*(x - 6)
Step-by-step explanation:
A quartic equation is a polynomial of degree 4.
Now, remember that for a polynomial of degree n, with leading coefficient A and zeros {x₁, x₂, ..., xₙ}
The polinomial can be written as:
p(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)
In this case we know that we have the zeros 4, 5 and 6.
Notice that this is a polynomial of degree 4 but we have 3 zeros, so one of them may be a double one, i will assume that is the 5.
And we have a leading coefficient that we do not know, let's call it A
Then we can write our polynomial as:
P(x) = A*(x - 4)*(x - 5)*(x - 5)*(x - 6)
Now we know that the polynomial passes through the point (7, 18), then:
P(7) = 18 = A*(7 - 4)*(7 - 5)*(7 - 5)*(7 - 6)
With this equation, we can find the value of A.
18 = A*(7 - 4)*(7 - 5)*(7 - 5)*(7 - 6)
18 = A*12
18/12 = A
(3/2) = A
Then our equation can be:
P(x) = (3/2)*(x - 4)*(x - 5)*(x - 5)*(x - 6)
