During his vacation, Dalyn rents a small boat from a rental service that charges a flat fee of $40 plus $20 per hour (including taxes).
The total charge comes to $120. Which equation can be used to calculate the number of hours, a, that Dalyn rents the boat?
Answer:
4 hours
Step-by-step explanation:
We can calculate this using the y=mx+c formula
y=total charge
m=per hour
x = (a) no. of hours
c= flat fee
y=20x+40
120=20x+40
We then solve like a normal equation
120-40=20x+40-40
80/20=20x/20
x=a
a=4
∴ Dalyn rents the boat for 4 hours

What figure will result when the triangle is rotated around RE?
Answer:
The figure will result is cone ⇒ B
Step-by-step explanation:
When a right triangle is rotated about its vertical leg 360°, then it formed a cone its radius is the horizontal leg of the triangle and its height is the vertical lege of the triangle
In the given figure
∵ Triangle TRE is a right triangle
∴ The horizontal leg is RE
∴ The vertical leg is TR
∵ The triangle is rotated around the horizontal leg RE 360°
∴ It formed a cone its radius = TR and its height = RE
∴ The figure will result is the cone
Ann, Ben, and Cheryl share some money in the ratio 3:7:10. Ben received £650 more than Ann.
Calculate the total amount of money that they shared.
Answer:
Total amount = £ 3250
Step-by-step explanation:
Ann : Ben : Cheryl = 3 : 7 : 10
Money Ann received = 3x
Money Ben received = 7x
Money Cheryl received = 10x
Ben received £650 more than Ann.
7x - 3x = 650
4x = 650
x = 650/4
x = £ 162.50
Money Ann received = 3x = 3 *162.50 = £ 487.50
Money Ben received = 7x = 7 *162.50 = £ 1137.50
Money Cheryl received = 10x = 10* 162.50 = £ 1625
Total amount = 487.50 + 1137.50 + 1625 = £ 3250

The rule that describes this transformation is R₀ 270°
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
If a point A(x, y) is rotated clockwise by 270 degrees, the new point is at A'(-y, x)
Quadrilateral PQRS is at P(-3, 5), Q(-1, 3), R(-3, 1) and S(-5, 3). If PQRS is rotated 270 degrees clockwise, the new point is at P'(-5, -3), Q'(-3, -1), R'(-1, -3) and S'(-3, 5)

Sebastián was saving $8.50 each week in order to have enough money for a phone that costs $122. If his father started him off with $25, write an inequality that can be used to determine the minimum number of whole weeks, w, Sebastián will need to save.
Step-by-step explanation:
122 - 25
97
y= 8.5x + 25
97/8.50 <
11.4 --> 12
x < 12
Answer:
25 + 8.50w ≥ 122
Step-by-step explanation:
Given that:
Amount saved per week = $8.50
Cost of phone = $122
Starting amount = $25
Minimum Number of whole weeks (w) Sébastien will need to save :
Starting amount + (weekly saving * number of weeks) ≥ 122
25 + 8.50w ≥ 122
8.50w ≥ 122 - 25
8.50w ≥ 97
w ≥ 97/8.50
w ≥ 11.4117
Number of whole weeks = 12
please help me. solve for X
Answer:
1. x = 16
2. x = 17
Step-by-step explanation:
1. The sum of the exterior angles of any polygon is 360 degrees. So, to find x, we can add up all of the angle measures and set them equal to 360, then solve for x:
46 + 93 + 47 + 4x + 62 + 3x = 360
Combine like terms:
248 + 7x = 360
Subtract 248 from both sides of the equation to isolate 7x:
7x = 112
Divide both sides by 7 to find the value of x:
x = 16
2. The sum of the interior angles for a 5-sided polygon is 540 degrees. So, to find x, we can add up all of the angle measures and set them equal to 540, and then solve for x:
5x + 139 + 9x + 71 + 92 = 540
Combine like terms:
14x + 302 = 540
Subtract 302 from both sides to isolate the 14x:
14x = 238
Divide both sides by 14 to find the value of x:
x = 17

3. If the perimeter of the rectangular fence is 16 units, prove, using the quadratic formula, that the solutions to the equation are x=1 and x=-3.2.
4. Using the first solution as x, show work and give the dimensions of the rectangular fence.
5. Using the second solution as x, show work and give the dimensions of the rectangular fence.
6. Explain which dimensions of the fence make sense in the context of the problem.
7. Using the dimensions from #6, what is the area of the rectangular fence?
Answer:
1. [tex]Perimeter = 10x^2+ 22x - 16[/tex]
2. [tex]Area = 6x^4 +28x^3 + 14x^2 - 48x[/tex]
3. [tex]x = 1[/tex] or [tex]x = -3.2[/tex]
4. [tex]Length = 0[/tex] and [tex]Width = 8[/tex]
5. [tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]
6. Second Solution
7. [tex]Area = 8.6016[/tex]
Step-by-step explanation:
Given
[tex]Length = 3x^2 + 5x - 8[/tex]
[tex]Width = 2x^2 + 6x[/tex]
Solving (1): The perimeter
Perimeter is calculated as thus:
[tex]Perimeter = 2 * (Length + Width)[/tex]
Substitute values for Length and Width
[tex]Perimeter = 2 * (3x^2 + 5x - 8 + 2x^2 + 6x)[/tex]
Collect Like Terms
[tex]Perimeter = 2 * (3x^2+ 2x^2 + 6x + 5x - 8 )[/tex]
[tex]Perimeter = 2 * (5x^2+ 11x - 8 )[/tex]
Open Bracket
[tex]Perimeter = 10x^2+ 22x - 16[/tex]
Solving (2): The Area:
Area is calculated as thus:
[tex]Area = Length * Width[/tex]
Substitute values for Length and Width
[tex]Area = (3x^2 + 5x - 8) * (2x^2 + 6x)[/tex]
Expand Bracket
[tex]Area = 2x^2(3x^2 + 5x - 8) + 6x(3x^2 + 5x - 8)[/tex]
Open Bracket
[tex]Area = 6x^4 + 10x^3 - 16x^2 + 18x^3 + 30x^2 - 48x[/tex]
Collect Like Terms
[tex]Area = 6x^4 + 10x^3 + 18x^3 - 16x^2 + 30x^2 - 48x[/tex]
[tex]Area = 6x^4 +28x^3 + 14x^2 - 48x[/tex]
Solving (3): If perimeter is 16, show that x = 1 and x = -3.2
In (a) [tex]Perimeter = 10x^2+ 22x - 16[/tex]
Substitute 16 for Perimeter
[tex]16 = 10x^2+ 22x - 16[/tex]
Equate to 0
[tex]10x^2+ 22x - 16 -16=0[/tex]
[tex]10x^2+ 22x - 32=0[/tex]
Expand
[tex]10x^2+ 32x -10x- 32=0[/tex]
Factorize
[tex]x(10x + 32) - 1(10x + 32) = 0[/tex]
[tex](x - 1)(10x + 32) = 0[/tex]
Split
[tex]x - 1 =0[/tex] or [tex]10x + 32 = 0[/tex]
[tex]x = 1[/tex] or [tex]10x = -32[/tex]
[tex]x = 1[/tex] or [tex]x = -32/10[/tex]
[tex]x = 1[/tex] or [tex]x = -3.2[/tex]
Solving (4): Using x = 1; Solve the dimension of the rectangle
We have that:
[tex]Length = 3x^2 + 5x - 8[/tex]
[tex]Width = 2x^2 + 6x[/tex]
Substitute 1 for x in the given parameters
[tex]Length = 3(1)^2 + 5(1) - 8[/tex]
[tex]Length = 3*1 + 5*1 - 8[/tex]
[tex]Length = 3 + 5 - 8[/tex]
[tex]Length = 0[/tex]
[tex]Width = 2(1)^2 + 6(1)[/tex]
[tex]Width = 2*1 + 6*1[/tex]
[tex]Width = 2 + 6[/tex]
[tex]Width = 8[/tex]
Solving (5): Using x = -3.2; Solve the dimension of the rectangle
We have that:
[tex]Length = 3x^2 + 5x - 8[/tex]
[tex]Width = 2x^2 + 6x[/tex]
Substitute -3.2 for x in the given parameters
[tex]Length = 3(-3.2)^2 + 5(-3.2) - 8[/tex]
[tex]Length = 3*10.24 + 5(-3.2) - 8[/tex]
[tex]Length = 30.72 -16 - 8[/tex]
[tex]Length = 6.72[/tex]
[tex]Width = 2(-3.2)^2 + 6(-3.2)[/tex]
[tex]Width = 2*10.24 + 6(-3.2)[/tex]
[tex]Width = 20.48 -19.2[/tex]
[tex]Width = 1.28[/tex]
[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]
Solving (6):
In the first solution of the dimensions in number 4, we have that
[tex]Length = 0[/tex] and [tex]Width = 8[/tex]
This dimension can not be considered because the length of a rectangle can not be 0
In the second solution of the dimensions in number 5, we have that
[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]
This dimension makes more sense because both dimensions are greater than 0
Solving (7): Using (6), determine the Area
In (6), we conclude that
[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]
So, Area is calculated as thus:
[tex]Area = Length * Width[/tex]
[tex]Area = 6.72 * 1.28[/tex]
[tex]Area = 8.6016[/tex]
Write an equation for the line in the given form.
slope is -5 and (5, 4) is on the line; standard form
Answer:
5x+y=29
Step-by-step explanation:
You use the information that is given and convert it into point-slope form y-y1=m(x-x1) like so. y-4= -5(x-5). Then you solve for y and you get y= -5x+29 which is slope intercept form (y=mx+b). Then you transform it into Standard form (ax+by=c) so all you do is add 5 on both sides and you get 5x+y=29. Now you have found your solution.

Answer:
C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.
Step-by-step explanation:
Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.
Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:
a = y/x = 15/5
a = 3
Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.
As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.
