which of the following numbers is closest to the mean

Answer:

192

Step-by-step explanation:

4(48)=X

In order to find the amount of people per bus-  4p=192 or 192÷4=p

To find the amount of people total on the field trip-  48×4=t or [tex]\frac{t}{4}=48[/tex]

To find the number of buses used- 192÷48=b or [tex]\frac{192}{b} =48[/tex]

The larger number is 40. Smaller number is 10.

Let's denote the smaller number as [tex]\( x \)[/tex] and the larger number as [tex]\( y \)[/tex].

According to the problem:

1. "Twice the smaller of two numbers is one half of the larger number" can be represented as:

[tex]\[ 2x = \frac{1}{2}y \][/tex]

2. "The larger number exceeds three times the smaller number by 10" can be represented as:

[tex]\[ y = 3x + 10 \][/tex]

Now we can solve this system of equations. Let's start by substituting the second equation into the first:

[tex]\[ 2x = \frac{1}{2}(3x + 10) \][/tex]

Multiplying both sides of the equation by 2 to eliminate the fraction:

[tex]\[ 4x = 3x + 10 \][/tex]

Subtracting [tex]\( 3x \)[/tex] from both sides:

[tex]\[ x = 10 \][/tex]

Now, substitute [tex]\( x = 10 \)[/tex] into the second equation to find [tex]\( y \)[/tex]:

[tex]\[ y = 3(10) + 10 \][/tex]

[tex]\[ y = 30 + 10 \][/tex]

[tex]\[ y = 40 \][/tex]

So, the larger number is [tex]\( 40 \)[/tex].

The perimeter of the parallelogram is 8√2.

In order to find this, we need to find the length between any of the points. You'll notice that you can create a right triangle between each set of consecutive points. As a result, you can draw the legs and use the Pythagorean Theorem. In each case, the legs will equal 2. So we find the length of the side as

Leg^2 + Leg^2 = Side^2

2^2 + 2^2 = s^2

4 + 4 = s^2

8 = s^2

√8 = s

2√2 =s

Now to find the perimeter, we multiply this length by 4.

4 * 2√2 = 8√2

The perimeter of the parallelogram with vertices at (-2, 0), (0, -2), (2, 0), and (0, 2) is 8sqrt2 units.

In order to find the perimeter of the parallelogram with vertices at (-2, 0), (0, -2), (2, 0), and (0, 2), you firstly need to calculate the distances between the vertices to determine the lengths of the sides. The formula to find the distance between two points (x1, y1) and (x2, y2) on a graph is given by sqrt((x2-x1)² + (y2-y1)²). If we apply this formula to our coordinates, we find that the lengths of the sides of the parallelogram are sqrt((0-(-2))² + (-2-0)²)) = 2sqrt2 and sqrt((2-0)² + (0-(-2))²)) = 2sqrt2. Since a parallelogram has two pairs of equal sides, we know that the four sides will have the same length. Therefore, the perimeter of the parallelogram is 4 * 2sqrt2 = 8sqrt2 units.

Answer:

A)  $18

B)   [tex]y=2.50x+18[/tex]

C)   Coefficient of x-term represents the cost for each ride ticket and constant term represents the cost of admission to the fair.

Step-by-step explanation:

(A)

The county fair charges $2.50 per ticket for the rides and Henry bought 15 tickets for the rides.

So, the total cost of the 15 tickets will be:  [tex](\$2.50*15)=\$37.50[/tex]

He spent total $55.50 on ride tickets and fair admission.

So, the cost of admission to the fair will be:  [tex](\$55.50-\$37.50)=\$18[/tex]

(B)

If [tex]x[/tex] represents the number of ride tickets and [tex]y[/tex] represents the total cost, then the cost for [tex]x[/tex] number of ride tickets is [tex]\$2.50x[/tex]

So, the linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission will be:   [tex]y=2.50x+18[/tex]

(C)

In the above linear equation, coefficient of x-term is 2.50, which represents the cost for each ride ticket.

And the constant term is 18, which represents the cost of admission to the fair.

Answer:

Answer (A)

Step-by-step explanation:

If the expression is indeed [tex]14\cdot 22x+350[/tex] with x representing the number of minutes after the first minute, then the first term, namely:

[tex]14\cdot 22x[/tex]

represents the 14 members handing out 22 fliers per additional minute. And the second term, namely:

[tex]350[/tex]

represents the number of fliers handed out in the first minute, which can be written as 350=14 x 25, so handed out by 14 members, 25 fliers each.

The above said is reflected in the wording of answer (A)

Solution :

We have to find all the possible solutions for the inequality [tex]2x+7<3x-5[/tex].

The given inequality can be solved as,

Subtracting 7 from both side , we get

[tex]2x+7-7 < 3x-5-7\\\\\Rightarrow 2x<3x-12[/tex]

Now, Subtracting 3x from both side, we get

[tex]2x-3x<3x-12-3x\\\Rightarrow -x <-12\\[/tex]

As we here we can see that both sides have similar sign, so we can cancel them out.

[tex]\Rightarrow x < 12[/tex]

Hence, the possible solution of the inequality  [tex]2x+7<3x-5[/tex] is [tex]x< 12[/tex]

*To solve for a variable, you have to isolate the desired variable onto 1 side

So firstly, subtract 2p on both sides of the equation: [tex]-a=p+b[/tex]

Next, subtract b on both sides of the equation, and your answer will be [tex]-a-b=p[/tex]

h^2 = b^2+p^2

21^2 = 17^2+x^2

441 = 289 + x^2

441-289 = x^2

122 = x^2

square root of 122 is x.

therefore, x= 11.04536102.

Answer:  12.32 is the answer.

Step-by-step explanation: Using the pythagorean thereom we can solve this by using the formula A^2+B^2=C^2.

We substitute in the values,

17^2+B^2=21^2.

Now we simplify.

289+B^2=441

We subtract the 289 from both sides,

B^2=152                                                                                                                                                            

Now we use square root to find the answer.

12.32 is the answer.

The amount received by me = $ x .

We are given " the amount she recives is 11 more than my amount" .

The amount of my friend's allowance is taken by the variavle y .

Therefore, we can repharse the given statement as :

" My friend's allowance y is 11 more than my allownace x" .

Now, we can seup an equation as:

y = 11 more than x.

Or

For " more than " pharase we would put a plus sign.

Therefore, y= x+11 is the final eqaution.

HI!

It's simple. If y = 14 when x = 8, you would divide 14 by 8, giving you 1.75. THen, you would multiply this with  12 to get your x value, 21.

Hope this helps!

Hey mate

Here's your answer

y varies directly as x:

y ~ x or can be also written as y = kx where k is a constant scalar value

given: y = 14 when x = 8

y = kx or

k = y/x = 14/8 = 7/4

k = 7/4

find x when y = 21

y = k*x

x = y/k = 21/(7/4) = 21 *4 /7 = 12

Hope it helps you!

Final answer:

The percent decrease in the price of the hand lotion is calculated by subtracting the sale price from the original price, dividing by the original price, and then multiplying by 100 to get the percentage. This results in a 20% decrease in price.

Explanation:

To find the percent decrease in the price of the hand lotion, we need to calculate the difference in price between the original and the sale price, then divide by the original price and multiply by 100.

Original price = $3.00
Sale price = $2.40

Price decrease = Original price - Sale price
Price decrease = $3.00 - $2.40
Price decrease = $0.60

Now, we calculate the percent decrease as follows:

Percent decrease = (Price decrease / Original price) x 100
Percent decrease = ($0.60 / $3.00) x 100
Percent decrease = 0.20 x 100

Percent decrease = 20%

The correct answer is C: 20%.

Solution: The value of x after solving both components is [tex]2<x\leq11[/tex] or [tex](2,11][/tex].

Explanation:

From the first component it is clearly noticed that the value of x is greater than 2.

Simplify the second component.

[tex]x-1\leq 10\\x\leq 11[/tex]

From the above inequality it is clearly noticed that the value of x is less than or equal to  11.

Solving both components we get [tex]2<x\leq11[/tex] and the graphical representation is shown in the figure.

The red portion shows the solutions of [tex]x>2[/tex], blue portion shows the solution of [tex]x-1\leq 10[/tex] and purple portion which combination of red and blue portion shows the solution of both inequalities.

Therefore, value of x after solving both components is [tex]2<x\leq11[/tex] or [tex](2,11][/tex].

The absolute-value equation representing the temperature variation in Leticia's apartment is |T - 68| = 3.5. Solving this, we have two possible temperatures: T = 71.5 (maximum) and T = 64.5 (minimum).

The topic of this Mathematics question is absolute value equations. We want to find the minimum and maximum temperatures in Leticia's apartment which can vary from the set thermostat level by 3.5 degrees. The absolute-value equation that can be used to represent this is:

|T - 68| = 3.5

'T' represents the actual temperature.

To solve the equation, we need to consider two situations. When the inside part of the absolute value, (T - 68), is positive or equals to zero, we just drop the absolute symbol, resulting in T - 68 = 3.5. Solving this, we get T = 71.5.

If the inside part of the absolute value, (T - 68), is negative, we have T - 68 = -3.5. Solving this, we get T = 64.5.

So, the maximum temperature is 71.5 degrees and the minimum is 64.5 degrees.

Answer:

Yes, it is possible for vertical lines to be parallel.

Step-by-step explanation:

If you have two vertical lines- say one at x=4 and one at x=5, the x coordinate will always equal either 4 or 5. Since 4 and 5 are not the same number, the two lines will never touch, making them parallel.

Vertical lines are considered parallel because they run straight up and down, do not intersect, and maintain the same distance apart, despite having an undefined slope.

Yes, it is possible for vertical lines to be parallel. By definition, parallel lines are two or more lines that never intersect and are always the same distance apart. While the slope of a vertical line is undefined because it would require dividing by zero (as there is no change in the x-value), this does not prevent vertical lines from being parallel. In fact, all vertical lines are parallel to each other because they all run straight up and down, and so they will never meet, regardless of the fact that we cannot assign them a numerical slope value.

An example of this can be seen when considering two vertical lines in a coordinate plane, such as x = 1 and x = 5. Both lines are straight up and down, they do not intersect, and the distance between them is consistent along their entire length, fulfilling the criteria for being parallel lines.

We have been given that

3x - y = 3 and

y = 2x + 2

Substitute y = 2x + 2 in the first equation, we get,

3x - (2x + 2) = 3

3x - 2x - 2 = 3

x - 2 = 3

x = 5

y = 2x + 2

= 2(5) + 2

= 12

Hence, the solution is (5, 12).

Hello there!

[tex]92 = -4(2r - 5)\\[/tex]

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to switch sides.

[tex]-4(2r-5)=92[/tex]

Then you divide by -4 from both sides of the equation.

[tex]\frac{-4(2r-5)}{-4}=\frac{92}{-4}[/tex]

Simplify

[tex]2r-5=-23[/tex]

Next you had to add by 5 from both sides of the equation.

[tex]2r-5+5=-23+5[/tex]

Simplify

[tex]2r=-18[/tex]

You can also divide by 2 from both sides of the equation.

[tex]\frac{2r}{2}=\frac{-18}{2}[/tex]

Simplify it should be the correct answer.

First to get rid of the parantheses we must multiply -4 times any number inside of the parantheses.

92=-4(2r-5)

92=-8r+20

Next subtract 20 from both sides

92=-8r+20

72=-8r

Divide both sides by -8

72=-8r

72/-8=-8r/-8

-9=r

Our final answer is -9
