Answer:
20 rides
Step-by-step explanation:
Let x represent how many rides you take.
Option A's cost can be represented by 0.8x + 30.
Option B's cost can be represented by 2.3x.
Set these expressions equal to each other, then solve for x:
0.8x + 30 = 2.3x
30 = 1.5x
20 = x
So, the costs will be the same at 20 rides
Select the two values of x that are roots of this equation.
X2 + 2x - 5 = 0
Answer:
[tex]x=-1+\sqrt{6 }[/tex]
[tex]x=-1-\sqrt{6 }[/tex]
Step-by-step explanation:
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
x² + 2x - 5 = 0
a = 1
b = 2
c = - 5
[tex]x=\frac{-2±\sqrt{2^{2}-4((1)(-5)) } }{2(1)}[/tex]
[tex]x=\frac{-2±\sqrt{4-4((1)(-5)) } }{2(1)}[/tex]
[tex]x=\frac{-2±\sqrt{4+20 } }{2(1)}[/tex]
[tex]x=\frac{-2±\sqrt{24 } }{2}[/tex]
[tex]x=\frac{-2±\sqrt{(2)(12) } }{2}[/tex]
[tex]x=\frac{-2±\sqrt{(2)(2)(6) } }{2}[/tex]
[tex]x=\frac{-2±\sqrt{(2)(2)(2)(3) } }{2}[/tex]
[tex]x=\frac{-2±(\sqrt{2} )(\sqrt{2})(\sqrt{(2)(3) )} }{2}[/tex]
[tex]x=\frac{-2±2\sqrt{6 } }{2}[/tex]
Two separate equations
[tex]x=\frac{-2+2\sqrt{6 } }{2}[/tex]
[tex]x=\frac{-2-2\sqrt{6 } }{2}[/tex]
[tex]x=-1+\sqrt{6 }[/tex]
[tex]x=-1-\sqrt{6 }[/tex]

If the diameter of the circle is 42 cm, then the area of the shaded area is
9514 1404 393
Answer:
781.4 cm²
Step-by-step explanation:
The shaded region consists of four (4) 30° sectors and eight (8) 60° segments. The formulas for the areas of these figures can be used.
area of sector = (1/2)r²θ
area of segment = (1/2)r²(θ -sin(θ))
For radius r, the area of the 4 sectors is ...
sector area = 4(1/2)(r²)(π/6) = (π/3)r²
and the area of the 8 segments is ...
segment area = 8(1/2)(r²)(π/3 -sin(π/3)) = 4r²(π/3 -√3/2) = (4/3)πr² -r²(2√3)
So, the total shaded area is ...
shaded area = r²(π/3 +4π/3 -2√3)
The radius of the circle is 21 cm, so the shaded area is ...
(21 cm)²(5π/3 -2√3) ≈ 781.4 cm²

length of wall is 13.5m calculate the area in cm2
Answer:
15 Apr 2018 — Area of path parallel to the remaining length of ... Area of parallelogram ABCD = AB × AE = 8 × 4 cm2 ... We can also calculate area of shaded portion by using area of..
Answer:
185.25 cm^2
Step-by-step explanation:
since only length is given i considered the wall as square shape. So given :
length = 13.5 cm
area of the wall = l^2
= 13.5^2
=182.25 cm^2

Solve the following equation for A. Be sure to take into account whether a letter is
capitalized or not.
q2 = g(-h + A)
Answer:
A = (q² + gh) / g
Step-by-step explanation:
Given equation:
q² = g(-h + A)
Solve for A
q² = g(-h + A)
q² = -gh + gA
Add -gh to both sides
q² + gh = -gh + gA + gh
q² + gh = gA
Divide both sides by g
(q² + gh) / g = gA / g
A = (q² + gh) / g

Which of the following best describes the equation below? 3(x + 9) + 6x = 9x - 27 A. no real solutions B. exactly one real solution, x = -1 C. exactly one real solution, x = D. infinite real solutions
Answer:
no solutions
Step-by-step explanation:
3(x + 9) + 6x = 9x - 27
Distribute
3x+27 +6x = 9x -27
Combine like terms
9x +27 = 9x -27
Subtract 9x from each side
27 = -27
This is never true so there are no solutions

Point J is on line segment \overline{IK} IK . Given IK=5x,IK=5x, IJ=4,IJ=4, and JK=4x,JK=4x, determine the numerical length of \overline{IK}. IK
Answer:
IK = 20
Step-by-step explanation:
If Point J is on the line segment IK, then;
IK = IJ + JK
Given that
IJ = 4
IK = 5x
JK = 4x
Substitute into the expression
5x = 4 + 4x
5x - 4x = 4
x = 4
Get the value of IK
IK = 5x
IK = 5(4)
IK = 20
Hence the numerical length of IK is 20

Please help 7th grade math
Answer:
d = 67.5
e = 22.5
Step-by-step explanation:
d + e = 90
d = 3e
Therefore, we can simply divide 90 by 4, which gives us 22.5, and also tells us what e equals. Then, multiply that by 3 to get d.

Ruth is knitting hats to sell at a local fair. The booth costs her $63 and the materials for each hat cost $10. She plans on selling them for $19. How many hats will Ruth have to make to break even, and how much will sales and costs be at that point?
Answer: Ruth have to make 7 hats to break even.
Step-by-step explanation:
Break even point is a point where Cost = Revenue.
Let x be the number of hats sold.
Given: Cost of booth = $63
Each hat cost = $10
Selling price for each cost = $19
As per given,
Total cost = Cost of booth+ (Cost of each hat)(Number of hats)
= 63+10x
Total selling price = 19x
For break even,
63+10x=19x
9x=63
x=7
Hence, Ruth have to make 7 hats to break even.
