Answer: The value of x = 5

Step-by-step explanation:

Given : ∠E and ∠F are vertical angles  m∠E = 8x + 8 and m∠F = 2x + 38.

We know that the vertical angles are congruent.

It means [tex]\angle{E}\cong\angle{F}[/tex]

[tex]\Rightarrow\ m\angle{E}=\ m\angle{F}[/tex]

[tex]\Rightarrow\ 8x+8=2x+38[/tex]

Subtract 2x and 8 from both sides , we get

[tex]6x=30[/tex]

Divide both sides by 6 , we get

[tex]x=5[/tex]

Hence, the value of x = 5

Proportional relationships are relationships with equal ratio. Mandy's conclusion is incorrect because the relationship is proportional, and it has a uniform ratio of 5.

To determine if the input and output are proportional, we simply divide the output (y) by the corresponding input (x).

i.e.

[tex]Ratio = \frac yx[/tex]

So, we have:

[tex]Ratio = \frac 51 = 5[/tex]

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

[tex]Ratio = \frac{25}{5} = 5[/tex]

[tex]Ratio = \frac{50}{10} = 5[/tex]

For the four input and output data, the ratios are equal (i.e. 5).

This means that the relationship is proportional.

Hence, Mandy's conclusion is incorrect

Mandy is correct about the proportional relationship as all the ratios of y to x in her table are equivalent to 5/1. However, there is an error with the last ratio listed as 10/50, which should be 50/10 to match the information in the table. After correcting this typo, it is clear that the relationship is proportional because all of the ratios simplify to the same value.

Mandy is indeed correct. For a set of ratios to represent a proportional relationship, they all must have the same value when simplified. From Mandy's table, the ratios formed from the inputs (x) and outputs (y) are 5/1, 10/2, 25/5, and 50/10. When simplified, these should give us a constant ratio if the relationship is proportional. Simplifying the ratios, we get:

Since all ratios simplify to the same number, 5/1, it indicates that the relationship between x and y is indeed proportional. However, the last ratio listed in the question, 10/50, is incorrect as it should be 50/10 to maintain consistency with the rest of the table. If we correct this ratio to 50/10, then all ratios confirm a proportional relationship.

To further validate this, a proportion can be created by setting two ratios equal to each other. For example, we can compare the first and the second ratio: 5/1 = 10/2. When you cross-multiply, the resulting equations, 5*2 = 10*1, are true, again confirming proportionality.

Answer:

P = 0.43h + 0.65p + 1.31d  represents the total profit, in dollars that the stand will make on a day when they sell h hot dogs, p pretzels, and d drinks

Step-by-step explanation:

Given :  The concession stand at a ballpark makes $0.43 profit from each hot dog sold. It also makes a profit of $0.65 from each pretzel sold and $1.31 from each drink sold

We have to find an expression that represents the total profit, in dollars that the stand will make on a day.

Let the stand sells h hot dogs, p pretzels, and d drinks on a day

Since profit of one hot dog is $ 0.43

So , profit of h hot dogs is $ 0.43h

also, profit of one pretzels is $ 0.65

So , profit of p pretzels is $ 0.65p

also, profit of one drink is $1.31

So , profit of d drinks  is $ 1.31d

Total profit of a day is the total profit he earned from selling each item.

thus, total profit is given by equation

P = 0.43h + 0.65p + 1.31d

Thus, P = 0.43h + 0.65p + 1.31d  represents the total profit, in dollars that the stand will make on a day when they sell h hot dogs, p pretzels, and d drinks

The required speed of the current is given as 9 miles per hour.

Given that,
A boat traveled 252 miles downstream and back. The trip downstream took 12 hours. The trip back took 84 hours. What is the speed of the boat in still water is to be determined.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,

let the speed of the current be y, and the speed of the boat at still water be x,
According to the question,
Downstream speed,
252 / 12 = x + y - - - -(1)
upstream speed,
252 / 84 = x - y  - - - (2)
Adding equations 1  and 2
21  + 3 = 2x
x = 24 / 2
x = 12 miles/hour
Now,
3 = 12  - y
y = 9 miles/ hour

Thus. the required speed of the current is given as 9 miles per hour.

Final answer:

To find the speed of the boat in still water and the current, we used the relation of speed, distance, and time for downstream and upstream travel to set up equations. We solved these to determine that the boat's speed in still water is 12 miles per hour, and the current's speed is 9 miles per hour.

Explanation:

The question asks to determine the speed of the boat in still water and the speed of the current given the distances and times for traveling downstream and upstream. Using the given data, we can set up two equations based on the speed-distance-time relationship:

Downstream speed = Speed of boat in still water + Speed of current

Upstream speed = Speed of boat in still water - Speed of current

Let v represent the speed of the boat in still water, and c represent the speed of the current. We have the equations:

(v + c) = 252 miles / 12 hours = 21 miles/hour (downstream)

(v - c) = 252 miles / 84 hours = 3 miles/hour (upstream)

Adding these two equations gives us:

2v = 24 miles/hour

Dividing by 2:

v = 12 miles/hour

Substituting v in either equation to find c:

c = 21 miles/hour - v = 21 miles/hour - 12 miles/hour

c = 9 miles/hour

Therefore, the speed of the boat in still water is 12 miles/hour, and the speed of the current is 9 miles/hour.

Answer:

  y = (-x -6)/2

Step-by-step explanation:

You want to solve x +2y = -6 for y.

The first step here is to get the y-term by itself on one side of the equal sign. We can do that by subtracting x from both sides of the equation.

  x +2y -x = -6 -x

  2y = -6 -x

Now, we divide by the coefficient of y to get y by itself.

  2y/2 = (-6 -x)/2

  y = (-x -6)/2

We can also write this as ...

  y = -x/2 -3

Answer:

The expression represents [tex]\( y \)[/tex] in terms of [tex]\( x \)[/tex] is [tex]\( y = \frac{-6 - x}{2} \)[/tex]

Explanation:

To solve the equation [tex]\(x + 2y = -6\)[/tex] for [tex]\(y\)[/tex], follow these steps:

1. Subtract [tex]\(x\)[/tex] from both sides of the equation to isolate the term containing [tex]\(y\)[/tex]:

[tex]\[2y = -6 - x\][/tex]

2. Divide both sides of the equation by [tex]\(2\)[/tex] to solve for [tex]\(y\):[/tex]

[tex]\[y = \frac{-6 - x}{2}\][/tex]

So, the solution for [tex]\(y\) is \(y = \frac{-6 - x}{2}\).[/tex]

The perimeter of the glass tabletop is 232 inches. The option (E) is correct.

To find the perimeter of the glass tabletop, we need to determine its dimensions first. According to the problem, the glass tabletop is 8 inches wider than the pedestal on each side.

Dimensions of the Pedestal:

- Width: 36 inches

- Length: 48 inches

Since the tabletop extends 8 inches beyond the pedestal on each side, we add 16 inches (8 inches on each side) to both the width and the length of the pedestal.

Width of the glass tabletop:

[tex]\[ \text{Width} = 36 \, \text{inches} + 16 \, \text{inches} = 52 \, \text{inches} \][/tex]

Length of the glass tabletop:

[tex]\[ \text{Length} = 48 \, \text{inches} + 16 \, \text{inches} = 64 \, \text{inches} \][/tex]

The perimeter [tex]\( P \)[/tex] of a rectangle is given by:

[tex]\[P = 2 \times (\text{Length} + \text{Width})\][/tex]

Substituting the dimensions:

[tex]\[P = 2 \times (64 \, \text{inches} + 52 \, \text{inches})\\P = 2 \times 116 \, \text{inches} = 232 \, \text{inches}\][/tex]

The correct perimeter of the glass tabletop is [tex]\( 232 \)[/tex] inches.

The complete question is:

A glass tabletop is supported by a rectangular pedestal. If the tabletop is 8 inches wider than the pedestal on each side, what is the perimeter of the glass tabletop?

A) 92 inches

B) 116 inches

C) 176 inches
