Answer:
$19
Step-by-step explanation:
the following equations can be determined from the question
5j + 2s = 208 equation 1
3j + 4s = 178 equation 2
where j = jeans
s = sweatshirts
simultaneous equation would be used to determine the values
Multiply equation 1 by 2
10j + 4s = 416 equation 3
subtract equation 2 from 3
7j = 238
j= $34
substitute for j in equation 1
5(34) + 2s = 208
2s = 38
s = $19

Now, looking at the inequalities, we can see that the second inequality does not have an equal to assigned
Whenever we want to plot this kind of inequality, we are going to use the dotted line in place of the thick line used in cases where we have the equal to assigned to the inequality
So, what this looks like is that only the option C has the correct representation of the dotted line and thus represents our answer

Inside a semicircular tunnel of diameter 30 feet, a vertical support beam is placed 6 feet from the side of the tunnel. How tall is the beam?
Answer:
The height of the beam is: [tex]h=12\: feet[/tex]
Step-by-step explanation:
The radius of the tunnel is r = 15 feet
The distance of the beam from the center of the tunnel is:
[tex]d_{beam}=15-6=9\: feet[/tex]
We have a right triangle, where:
The Hypotenuse is 15 feetOne side is 9 feetThe other side is the height of the beamLet's use Pythagoras theorem.
[tex]15^{2}=9^{2}+h^{2}[/tex]
[tex]h^{2}=15^{2}-9^{2}[/tex]
[tex]h=\sqrt{15^{2}-9^{2}}[/tex]
Therefore, the heigh of the beam is:
[tex]h=12\: feet[/tex]

Choose all of the equations that represent a parabola with the focus (0,4) and the vertex (0, -6).
A. x2 = 20 (y + 1)
B. x2 = 40 (y + 6)
C. 20y = x2 - 20
D. 40y = (x + 6)2
E. 40y = x2 – 240
Answer:
B and E
Step-by-step explanation:
The equations that represent a parabola with the focus (0,4) and the vertex (0, -6) are 40y = [tex]x^{2}[/tex] - 240 and [tex]x^{2}[/tex] = 40 (y + 6)
What is parabola?A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.
The general equation of a parabola is:
[tex](y -k)^{2}[/tex] = 4a(x − h) for horizontal parabola
[tex](x - h) ^{2}[/tex]= 4a(y − k) for vertical parabola
where (h,k) denotes the vertex
a = point of focus
According to question
focus of parabola :(0,4)
vertex of parabola (h,k): (0, -6)
now, form points given
a = 4 − (-6) = 10 as x coordinates are the same.
Since the focus lies to the left of vertex, a = 10
By The general equation of a parabola :
[tex](x - h) ^{2}[/tex]= 4a(y − k) for vertical parabola
[tex](x - 0)^{2}[/tex] = 4*10(y-(-6))
[tex]x^{2}[/tex] = 40 (y + 6) --------------------- (1)
or
[tex]x^{2}[/tex] = 40y + 240
40y = [tex]x^{2}[/tex] - 240 ---------------------------(2)
Therefore , parabola can be represented by equation (1) and (2).
Hence, the equations that represent a parabola with the focus (0,4) and the vertex (0, -6) are 40y = [tex]x^{2}[/tex] - 240 and [tex]x^{2}[/tex] = 40 (y + 6)

1 over 3b = 4 over 5. Which of the following equals b in this equation?
22 over 5
11 over 8
2 over 5
1 over 4
Answer:
b = 5/12
Step-by-step explanation:
1. Cross multiply -> 1 x 5 = 5 and 3b x 4 = 12 b
2. Simplify -> 5 = 12b and switch sides so it's easier: 12b = 5
3. Divide both sides by 12 -> 12b ÷ 12 = b and 5 ÷ 12 = 5/12
4. So, the answer is b = 5/12

Find the area of the figure below. * 23 cm 12 cm 18 cm 15 cm
The area of the figure = area of trapezium + area of rectangle = 420 cm².
What is the Area of a Trapezium and Area of a Rectangle?Area of trapezium = 1/2(a + b)h
Area of rectangle = length × height.
The area of the figure = area of trapezium + area of rectangle
The area of the figure = 1/2(a + b)h + length × height
Plug in the values
The area of the figure = 1/2(23 + 15)6 + 23 × 12
The area of the figure = 144 + 276
The area of the figure = 420 cm²

https://brainly.com/question/16904048
Answer: The area is 390 cm
Step-by-step explanation:
All you have to do is find the area of the trapezoid and the area of the rectangle and add them together.
Area of trapezoid formula: A = 1/2 (Base 1 + Base 2)h
base 1 = 15 cm
base 2 = 23 cm
height = 6 (18-12)
so, 15 + 23 = 38
38 x 6 = 228
228 x 0.5 or 1/2 = 114
Therefore the area of the trapezoid is 114 cm
Area of rectangle formula: A = bh
base = 23
height = 12
12 x 23 = 276
Therefore the area of the rectangle is 276 cm
Now add the values together, 114 + 276 = 390
390 is the area of the figure
Factor the polynomial expression x^4 + x^2 − 20.
The factors of polynomial expression x^4 + x^2 − 20 is [tex](x - \sqrt{5})(x + \sqrt{5})(x - i \sqrt{5})(x + i \sqrt{5})$[/tex].
We are given that;
The polynomial expression =[tex]x^4 + x^2 − 20.[/tex]
Now,
To factor a polynomial expression, we need to find the common factors of each term and then use the distributive property to write the expression as a product of two or more factors.
For example,[tex]x^4 + x^2 − 20[/tex] can be written as:
[tex]$x^4 + x^2 - 20 = x^2(x^2 + 1) - 20$[/tex]
We can use the difference of squares formula to factor x^2 + 1 and 20:
[tex]$x^2 + 1 = (x + i)(x - i)20 = (2 \sqrt{5})(2 \sqrt{5})[/tex]
where i is the imaginary unit such that i^2 = -1. Now, we can write the expression as:
[tex]$x^4 + x^2 - 20 = x^2(x + i)(x - i) - (2 \sqrt{5})(2 \sqrt{5})$[/tex]
We can use the difference of squares formula again to factor the whole expression:
[tex]$x^4 + x^2 - 20 = (x^2 - 2 \sqrt{5})(x^2 + 2 \sqrt{5})$[/tex]
we can still factor each factor further into prime factors. We have:
[tex]x^2 - 2 \sqrt{5} = (x - \sqrt{5})(x + \sqrt{5})$\\$x^2 + 2 \sqrt{5} = (x - i \sqrt{5})(x + i \sqrt{5})[/tex]
Therefore, by factorization answer will be [tex](x - \sqrt{5})(x + \sqrt{5})(x - i \sqrt{5})(x + i \sqrt{5})$[/tex]

Write the equation in standard form for the circle with center (-5, 3) and radius 10.
Answer:
x² + y² +10x -6y - 69 = 0
Step-by-step explanation:
We need to write the standard equation of circle with , centre (-5,3) and radius 10 unit . The Standard equation of the circle ⭕ is ,
=> ( x - (-5))² + (y -3)² = r²
=> ( x +5)² + (y-3)² = 10²
=> x² + 25 + 10x + y² +9-6y = 100
=> x² + y² +10x -6y + 31 = 100
=> x² + y² +10x -6y - 69 = 0
• Hence the equation of the circle is x² + y² +10x -6y - 69 = 0.1a.) Brian borrowed 4 non-fiction books from the library. This was 25% of the

How do you find an area of an object?
Answer:
Step-by-step explanation: The easiest territory computations are for squares and square shapes. To discover the space of a square shape, duplicate its tallness by its width. For a square, you just need to discover the length of one of the sides (as each side is a similar length) and afterward duplicate this without anyone else to discover the region.
