Which table of ordered pairs represents a proportional relationship

Answers

Your answer is (B.) because 2 times 5 is 10. 4 times 5 is 20. and 6 times 5 is 30, these make proportional relationships.

Answer:

The second table.

Step-by-step explanation:

In this case, "a proportional relationship" refers to the presence of a constant of variation between variables, that is, variables must variate at the same rate, where such rate is call the constant of proportionality.

Notice that the second table fulfils this definion, because x-variable variates 2 units, while y-variable variates ten units. To find the constant of proportionality, we just need to divide

[tex]k=\frac{10}{2}=5[/tex]

Which means that y-variable represents five times x-variable, let's evalute to prove this

[tex]2 \times 5=10\\4 \times 5 = 20\\6 \times = 30[/tex]

Notice that we got all y-values.

Therefore, the right table is the second one, it presents a proportional relationship.

A scout troop planned to take a bus for an overnight trip to a campground in a nearby state. The bus will cost $360 to rent. The bus company told them that if they could get 3 more troop members to join in the trip each person could pay $6 less to go on the trip. If the troop was able to find the 3 additional people to join the trip, which answer is the most reasonable for the number of members that went on the trip?

Answers

Let x represent the number originally signed up.
.. 360/x -6 = 360/(x +3)
.. 360*(x +3) -6x(x +3) = 360x . . . . . multiply by the product of denominators
.. 360x +1080 -6x^2 -18x = 360x
.. x^2 +3x -180 = 0
.. (x +15)(x -12) = 0
Solutions are x = {-15, 12}

12 members went on the trip.
_____
The problem wording does not make clear whether the original number (12) or the number suggested by the bus company (15) went on the trip. It would be most reasonable for 15 to go, if the troop had people who were willing.

Final answer:

The answers identified are: (C) for the first sequence question, (A) for the second sequence question, (D) for the arithmetic sequence with a start of 8 and difference -2, (C) for the arithmetic sequence starting from -17, (B) for the arithmetic sequence question with given a19 and a21, and finally an = 200 + 0.5n for the tree growth question.

Explanation:

The correct answers are as follows:

For the first question, you start with 4 (a1 = 4) and each subsequent term is the previous term plus 8 (an = an-1 + 8). This gives the sequence 4, 12, 20, 28, 36, 44, which matches option (C).For the second question, starting at -8 (a1 = -8) and then multiplying the previous term by 5 gives you -8, -40, -200, -1000, -5000, -25,000, which matches option (A).For the third question, the common difference between consecutive terms is -2 and the first term is 8, which gives an = 8 - 2(n - 1) (option D)For the fourth question, the common difference is +5 and the first term is -17, so the equation for the nth term is an = -17 + 5(n - 1) (option C). For the fifth question, the common difference can be calculated from the problem as 53. Hence the equation for the nth term is an = 896 - 53(n - 1) (option B).For the last question, if the tree grows at a rate of 0.5 cm per week and the initial height is 200 cm, the height of the tree each week is represented by an = 200 + 0.5n.

∆ABC has side lengths of 10 units, 20 units, and 24 units. ∆XYZ is similar to ∆ABC, and the length of its longest side is 60 units. The perimeter of ∆XYZ is units. If the height of ∆ABC, with respect to its longest side being the base, is 8 units, the area of ∆XYZ is square units. NextReset

Answers

To find the perimeter of triangle XYZ, you will need to find out how many groups of 24 it takes to get 60(both are the longest sides). The answer is 2.5 (You divide to get this). You then multiply the other 2 sides (20 and 10) by 2.5. The other two sides would be 50 and 25. Add 60+50+25 to get a perimeter of 135 units. To find the area, you will use the same factor (2.5) to find the height of triangle XYZ. So, 8 x 2.5= 20 for the height of triangle XYZ. Please see the picture to help further understand this relationship and see the work for finding the area of triangle XYZ.

Final answer:

The perimeter of ΔXYZ is 25 units and the area of ΔXYZ is 40 square units.

Explanation:

In this problem, we are given that ΔABC has side lengths of 10 units, 20 units, and 24 units, and ΔXYZ is similar to ΔABC. We are also given the length of the longest side of ΔXYZ as 60 units. To find the perimeter of ΔXYZ, we need to add up the lengths of all its sides. Since the longest side of ΔABC is 24 units, and the longest side of ΔXYZ is 60 units, we can set up the following proportion:

24/10 = 60/x

Cross-multiplying gives us:

24x = 600

x = 600/24 = 25 units

Therefore, the perimeter of ΔXYZ is 25 units.

Now, to find the area of ΔXYZ, we can use the proportional relationship between the areas of similar triangles. Since the ratio of the longest sides is 60/24 = 5/2, the ratio of the areas will be (5/2)^2 = 25/4. Since the area of ΔABC is 1/2 times the base times the height, we can use the same formula for ΔXYZ with the corresponding measurements:

Area of ΔXYZ = (1/2) * 10 * 8 = 40 square units

The solution to the equation is [tex]x = \frac{3}{4}[/tex] .

We start by rewriting the equation:

4x-7+7x=3x-1

Combine the x terms on the left side:

11x - 7 = 3x - 1

Isolate the x terms on one side of the equation. To do this, we’ll move the 3x term from the right side to the left side by subtracting 3x from both sides:

11x - 3x - 7 = -1

Simplify:

8x - 7 = -1

Add 7 to both sides to get rid of the constant term on the left side:

8x = 6

Divide both sides by 8 to find the value of x:

[tex]x = \frac{6}{8} = \frac{3}{4}[/tex]

559 tickets were sold 59 more student tickets were sold than adult tickets how many adult tickets were sold

Answers

Let s = number of student tickets and a = number of adult tichets;
We have the equation: s + a = 559 and s = 59 + a;
Then, we solve the equation: 59 + a + a = 559;
59 + 2a = 559;
2a = 500;
a = 500/2;
a = 250;
s = 59 + 250;
s = 309;

The number of adult tickets sold will be 250.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Suppose the number of student tickets is S while adult tickets are A.

As per the given,

59 more student tickets were sold than adult tickets.

S = A + 59

S - A = 59

Total tickets S + A = 559

Add both equations as

S - A + S + A = 559 + 59

2S = 618

S = 309

A = 309 - 59 = 250

Hence "The number of adult tickets sold will be 250".

For example, 14, 1⁄4 and 1/4.are different ways of writing the same fraction (in this case a quarter). The top number tells us how many parts there are, and the bottom number tells us the total number of parts. The top part of the fraction is called a numerator. The bottom part of the fraction is called a denominator. For example, for the fraction 14 the 1 is the numerator, and the 4 is the denominator.

Two variables vary inversely if their product is constant (does not change). The variables w and t vary inversely so their product wt = k were k is a constant. Solving this for t we get t=k/w

We are told that w = 4 and t = 1/5 so we know their product wt = (4)(1/5) = 4/5. This is what I called k before.

Therefore the relationship between w and t can be modeled by t = (4/5) / w. That is, t = 4 / 5w

Further, when w = 9, we find t by substituting 9 for w in the equation just found and obtain: t = 4 / [(5)(9)] = 4/45. That is, when w = 9, t = 4/45.

This mean choice D is the correct answer.

The answer is D. t=4/5w; 4/45

Which equation is quadratic in form 2(x+5)^2+8x+5+6=0, x^6+6x^4+8=0, 7x^6+36x^3+5=0, 4x^9+20x^3+25=0?

Answers

Equation 2(x+5)² + 8x + 5 + 6 = 0 or 2x² + 28x + 61 = 0 is the equation in quadratic form.

What is a quadratic equation?

A quadratic equation is an equation of second order. Quad implies the square power, it is also called equation of degree 2.

The standard form of a quadratic equation is ax² + bx + c = 0.

Where a, b and c are constants.

In the given equation,

2(x+5)² + 8x + 5 + 6 = 0

2 (x² + 25 + 10x) + 8x + 11 = 0

2x² + 50 + 20x + 8x + 11 = 0

2x² + 28x + 61 = 0

This is the quadratic equation.

Rest of the equation are in the higher degree power, only equation 2x² + 28x + 61 = 0 is second power equation.

Hence, 2x² + 28x + 61 = 0 is a quadratic equation.

whats the value of x??im really confused i thought it was 7 but that doesnt make sense can someone please help me!!!

Answers

10x-20 + 6x+8 = 180

16x -12 = 180
16x = 192
x = 192/16
x = 12
These angles are supplementary
meaning they both add up to 180 because they are on a straight line
To solve:
(10x - 20) + (6x + 8) = 180
combine like terms
(10x + 6x ) + (-20 + 8) = 180
16x - 12 = 180
add 12 to both sides
16x = 192
divide both sides by 16
x = 12

To solve for the angles, you would just take x and plug it into the angle and solve XD

Hope this helps

The main arena hall has dimensions 200 m by 85 m. On a large diagram on the office wall the scale is 1:40. What are the dimensions of the floor space on the diagram?

Answers

Answer:

500 cm by 212.5 cm

Step-by-step explanation:

Using the scale 1:40 on the 200 m dimension, we have 200/40 = 5 m.  Each meter is 100 cm; this makes this 5(100) = 500 cm.

Using the scale on the 85 m dimension, we have 85/40 = 2.125 m.  Each meter is 100 cm; this makes this 2.125(100) = 212.5 cm.

Answer:

500 cm by 212.5 cm

Step-by-step explanation:

Given :

The main arena hall has dimensions 200 m by 85 m.

On a large diagram on the office wall the scale is 1:40.

To Find: What are the dimensions of the floor space

Solution :

Length of arena hall = 200 m

Scale is 1:40

So, the length of the floor = [tex]\frac{200\times 1}{40}[/tex]

                                           =  [tex]5m[/tex]

Since 1 m = 100 cm

So, 5 m = 100*5 = 500 cm

Width of arena hall  = 85 m

So, width of floor = [tex]\frac{85\times 1}{40}[/tex]

                             =  [tex]2.125m[/tex]

Now 1 m = 100 cm

So, 2.125 m = 212.5 cm

Thus the dimensions of floor is 500 cm by 212.5 cm
