3. -2 \leq -2 Subtract 6 from both sides, then 8, and then 2

4. -4 < 8 Divide both sides by -4, then by -2

5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?

Answers

Answer 1
864 < 151213 > 0-18 ≤ -18-1/2 < 1

What is inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given few inequalities and some operations are performed on them

For first inequality:

=> 4 < 7

Multiply both sides by 3, then by 2, then by 4, then by 9

=> 4 *3 * 2 * 4 * 9 < 7  *3 * 2 * 4 * 9

=> 864 < 1512

there is no change in the inequality sign and it is still true.

For the second inequality:

=>11 > -2

Add 3 to both sides, then add 3, then add (-4)

=> 11 +3 + 3 + (-4) > -2 + 3+3 + (-4)

=> 13 > 0

there is no change in the inequality sign and it is still true.

For the third inequality:

=> -2 ≤ -2

Subtract 6 from both sides, then 8, and then 2

=> -2 -6 -8 -2 ≤  -2 -6 -8 -2

=>  -18 ≤ -18

there is no change in the inequality sign and it is still true.

For the fourth inequality:

=> -4 < 8

Divide both sides by -4

=> -4 / -4 < 8 / -4

Since, after dividing or multiplying on both sides by a negative sign, inequality changes its sign

=> 1 > -2

Divide both sides by -2

=> -1/2 < 1

there are two times a change in the inequality sign and it is still true.

Two vehicles start from the same point traveling in the same direction. One vehicle travels 55.5 miles per hour (mph) and the other 45 ¼ mph. When will the two cars be 350 miles apart?

Answers

The number of hours after which the cars will be 350 miles apart is 34 hours.

What is speed?

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Vehicle 1.

Speed = 55.5 mph

Distance(1) = 55.5 x Time

Vehicle 2.

Speed = 45(1/4) mph

Distance(2) = 45(1/4) x Time

The difference in the distance = 350 miles.

Distance(1) - Distance(2) = 350

55.5 x Time - 45(1/4) x Time = 350

55.5 x Time - (181/4) x Time = 350

(55.5 - 181/4) x Time = 350

Time = 350 / (55.5 - 45.25)

Time = 350 / 10.25

Time = 34 hours.

What are the slope and y-intercept of the line that models this situation? I

Answers

The slope and the y-intercept of the given data table will be option A) Slope= -0.0018, y-intercept = 212

The y-intercept of any linear equation is the point at which the line or the curve intersects the vertical i.e the Y- axis.

To find this intercept, the value of x is taken to be 0 in the model, since on the Y-axis, the value of x is 0.

Here from the given table, we need to check the boiling point or the value of Y for which the value of the altitude or the x value is 0

Hence we get the y-intercept as 212° F.

Now, the formula for slope

= change in y/ change in x

here we will take any two data rows and divide the difference in boiling points by the difference in altitudes.

Taking the first 2 rows gives us

Slope = -0.9/500

Bella begins to walk from her house toward her friend Ella's house. At the same time, Ella begins to ride her bicycle toward Bella's house. They each maintain a constant speed, and Ella rides 5 times as fast as Bella walks. The distance between their houses is 2 miles, which is 10,560 feet, and Bella covers $2\frac{1}{2}$ feet with each step. How many steps will Bella take by the time she meets Ella

Answers

Since Bella takes 4,224 steps, and Ella takes 844.8 steps, they meet at 4,224 steps.

To determine this:

We can start by using the information given to find out how long it takes Bella and Ella to meet.

Since Ella rides 5 times faster than Bella walks, we can use the following equation to find out how long it takes each of them to cover the 2-mile distance:

Time (Ella) = Time (Bella) / 5

We can also use the distance formula to find out how long it takes Bella to cover the 2-mile distance:

Distance = Speed x Time

We know that Bella's speed is [tex]$2\frac{1}{2}$[/tex]  feet per step, and the distance between their houses is 10,560 feet. So:

10,560 feet = [tex]$2\frac{1}{2}$[/tex] feet/step x Time (Bella)

Solving for Time (Bella), we get:

Time (Bella) = 10,560 feet / [tex]$2\frac{1}{2}$[/tex] feet/step = 4,224 steps

Now we can use this information to find out how long it takes Ella to meet Bella:

Time (Ella) = Time (Bella) / 5 = 4,224 steps / 5 = 844.8 steps

And since Bella takes 4,224 steps, and Ella takes 844.8 steps, they meet at 4,224 steps.

Suppose that $2000 is loaned at a rate of 7%, compounded semiannually. Assuming that no payments are made, find the amount owed after 4 years.

Answers

Answer:

$2581.60

Step-by-step explanation:

In order to find the amount owed after 4 years, we need to use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the amount owed after t years

P is the principal, or initial amount borrowed

r is the interest rate

n is the number of times the interest is compounded per year

t is the number of years

Plugging in the given values, we have:

A = $2000(1 + 0.07/2)^(2*4)

= $2000(1.035)^8

= $2000(1.2908)

= $2581.60

Therefore, the amount owed after 4 years would be $2581.60.

-0. 44, -3/8, -0. 5, -2/5

Answers

The order from greatest to least is -3/8> -2/5>-0.44>-0.5

To compare all the numbers, we first convert the numbers to their fractional equivalent.

Therefore, -0.44= -44/100

And -0.5= -5/10

Now, we covert all the numbers to get the same denominator in all the numbers, therefore, let the denominator be 100

Therefore, we multiply -3/8 with 12.5 in both numerator and denominator to get, -37.5/100

Then, we multiply -2/5 with 20 in both numerator and denominator to get, -40/100

and, we multiply -5/10 with 10 in both numerator and denominator to get -50/100

Therefore, with these resultant value we can say that, -37.5/100> -40/100 >-44/100> -50/100

Given is the expression as follows -

√{(x + c)² + y²} = x (a/c) + a

√{(x + c)² + y²} = xa/c + a

√{(x + c)² + y²} = a{x/c + 1}

√{x² + c² + 2xc + y²} = a{x/c + 1}

{x² + c² + 2xc + y²} = ± (a{x/c + 1})²

Now, we can write -

and

{x² + c² + 2xc + y²} = - (a{x/c + 1})²                 ......... (2)

Solving (1) as -

{x² + c² + 2xc + y²} = (a{x/c + 1})²    

{x² + c² + 2xc + y²} = a²(x/c + 1)²

{x² + c² + 2xc + y²} = a²(x²/c² + 1 + 2x/c)

{x² + c² + 2xc + y²} = (a²x²/c² + a² + 2a²x/c)

y² = (a²x²/c² + a² + 2a²x/c) - (x² + c² + 2xc)

y = √{ (a²x²/c² + a² + 2a²x/c) - (x² + c² + 2xc)}

Solving (2) as -

{x² + c² + 2xc + y²} = - (a{x/c + 1})²                

y² =  - (a{x/c + 1})² - (x² + c² + 2xc)

3) 1,040

4) 880

Answers

The estimated revenue, in dollars, that the club will generate when the bags are priced at $13 each is 3) 1,040.

What is the revenue formula?

The revenue formula is the multiplication of the number of units sold and the price per unit.

To determine the total revenue, we must first ascertain the unit price and the quantity sold.

We know that market forces and the competitive environment determine the quantity sold or supplied.

The demand for tote bags at $11 = 100 units

Decrease in demand for every $1 price increase = 10 units

When the price is $13 each, the units to be sold = 80 (100 -10 x 2)

The total revenue at $13 each = $1,040 (80 x $13)

Total revenue at $12 each = $1,080 (90 x $12)

Total revenue at $11 each = $1,100 (100 x $11)

Thus, we can conclude that the club generates less revenue when it increases its price per tote bag from $11 to $13, justifying the interactions between supply, demand, and cost.

How to calculate the margin of error?

given, mean GPA of 75 sophomores = 3.26 = Xi

standard deviation = 0.62 = s

sample number = 75 = n

total sophomores = 500

z value of the sophomores = mean / standard deviation = 3.26 / 0.62

Z value = 5.26

margin of error = Z value × standard deviation / (√number of sample)

margin of error = 5.26 × 0.62/ √ (75)

                      = 0.376

What should be added to XXYY to obtain 2x² 3xy?

Answers

(a) x² + 2xy - y² must be added to x² + xy + y² to get 2x² + 3xy. (b)  5a + b -6 must be subtracted from 2a + 8b + 10 to get -3a + 7b + 16.

a)

Here we are given the expression x² + xy + y²

Now we need to add something so that this expression becomes x² + 3xy

Let the expression to be added be p.

Hence we get

x² + xy + y² + p = 2x² + 3xy

or, p = 2x² + 3xy - (x² + xy + y²)

or, p = 2x² + 3xy - x² - xy - y²

or, p = x² + 2xy - y²

Hence, x² + 2xy - y² must be added.

b)

Here we are given the expression 2a + 8b + 10

We need to subtract another expression to get -3a + 7b + 16

Let the expression be t. Hence we get

2a + 8b + 10 - t = -3a + 7b + 16

or, t = 2a + 8b + 10 - (-3a + 7b + 16)

or, t = 2a + 8b + 10 + 3a - 7b - 16

or, t = 5a + b - 6

Hence 5a + b - 6 must be subtracted,

Answer:

19.56

Step-by-step explanation:

PR = [tex]\sqrt{3^{2} + 3^{2} }[/tex] = [tex]\sqrt{18}[/tex] = 3[tex]\sqrt{2}[/tex]

RQ = [tex]\sqrt{5^{2} +5^{2} }[/tex] = [tex]\sqrt{50}[/tex] = 5[tex]\sqrt{2}[/tex]

QP = [tex]\sqrt{8^{2} +2^{2} }[/tex] = [tex]\sqrt{68}[/tex] = 2[tex]\sqrt{17}[/tex]

Perimeter = sum of the sides = 3[tex]\sqrt{2}[/tex] +  5[tex]\sqrt{2}[/tex] +  2[tex]\sqrt{17}[/tex] = 19.56

Break the triangle PQR into 3 right triangles, with each leg being a hypotenuse.  Then you can use the Pythagorean theorem to find the length of each leg.  Add them all together to get the perimeter.
