A family buys airline tickets online. Each ticket costs $208. The family buys travel
insurance with each ticket that costs $16 per ticket. The web site charges a fee of
$22 for the entire purchase. The family is charged a total of $1142. How many
tickets did the family buy

Answers

the family brought 2271 tickets.

Answer:

5 tickets

Step-by-step explanation:

Each ticket costs $224 including the travel insurance and they are charged $22 regardless of the number of tickets they buy.

Therefore, the equation is 224x + 22 = 1142

First, you have to subtract the 22 from both sides to amount to 224x = 1120

Now, you divide 224 from 1120 to get 5

Answer:

  A.  x −3y = 6; 5x −y = 10

Step-by-step explanation:

The first table gives the x- and y-intercepts, so you can write the equation for the line in intercept form as ...

  x/a +y/b = 1 . . . . . . x-intercept = a; y-intercept = b

The x-value with y=0 is a=6; the y-value with x=0 is b=-2. So, the equation of the line for the first table is ...

  x/6 +y/-2 = 1

Multiplying by 6 gives ...

  x -3y = 6

The only matching equation is in answer choice A.

__

You can check that the second given equation in choice A matches the second table:

for (x, y) = (-3, -25), you have ...

  5(-3) -(-25) = -15 +25 = 10 . . . . as required

The axis of symmetry of a parabola is the line x = 6. What is the x-coordinate of the vertex of the parabola?

Answers

Answer:

x-coordinate of the vertex: h = 6.

Step-by-step explanation:

The axis of symmetry is an imaginary line that divides the graph of a parabola into two congruent parts.  The vertex of a parabola, (h, k) is the point where the graph intersects the axis of symmetry.

In the standard form of quadratic equation, y = ax² + bx + c:

[tex]\large \sf{axis\:of\:symmetry:\:x\:=\:\frac{-b}{2a}}[/tex]

In the vertex form of quadratic function, y = a(x - h)²+ k:

[tex]\large \sf{axis\:of\:symmetry:\:h\:=\:\frac{-b}{2a}}[/tex]

Hence, the axis of symmetry is the point where x = h.  

Given these definitions, we can infer that the x-coordinate of the axis of symmetry is the same as the x-coordinate of the vertex, where h = 6.

3. Marilyn hit a golf ball on the ground with her driver. Use

the general function for a projectile to write a function

that shows the height in feet of her golf ball as a function

of time. The ball was hit with an initial vertical velocity of

130 feet per second.

h(t) = -16t2 + 130t


a) How long will Marilyn's ball stay in the air?


b) What was the maximum height of the ball?

Answers

It will take the ball 4.0625secs to stay in the air

The maximum height of the ball is 264.0625m

Given the function representing the height reached by the golf expressed as;

h(t) = -16t^2 + 130t

The velocity function is expressed as:

v(t) = -32t + 130

At maximum height, the velocity of the ball will be zero, i.e v(t) = 0

0 = -32t + 130

32t = 130

t = 130/32

t = 4.0625

Hence it will take the ball 4.0625secs to stay in the air

b) Substitute t = 4.0625 into the height function to have:

h(t) = -16t^2 + 130t

h(t) = -16(4.0625)^2 + 130(4.0625)

h(4.0625) = -264.0625 + 528.125

h(t) = 264.0625m

Hence the maximum height of the ball is 264.0625m

Ms. Mary spent $192 less than Ms.Mona on supplies for their class. Together they spent a total of $988. How much did each person spend?

Answers

Answer:

Ms. Mona and Ms. Mary spent $590 and $398 respectively.

Step-by-step explanation:

Total spent= $988

Ms. Mary +Ms. Mona= $988

Since Ms. Mary spent $192 less than Ms. Mona,

(Ms. Mona -$192) +Ms. Mona= $988

2(Ms. Mona)= $988 +$192

2(Ms. Mona)= $1180

Amount Ms. Mona spent

= $1180 ÷2

= $590

Since Ms. Mary spent $192 less than Ms. Mona,

amount Ms. Mary spent

= $590 -$192

= $398

Alternatively, since the total spending is $988,

amount Ms. Mona spent

= $988 -$590

= $398

What is a expression? What is a mathematical equation? What is Equation Modelling? What is inequality?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. An inequality is a relation comparing two expressions. For example -

3x + 4 > 5

ax + b < c

We have the following inequality -

r - 10 > -7

We can write -

r - 10 > -7

r - 10 + 10 > - 7 + 10

r > 3

Therefore, for r > 3, the inequality r - 10 > -7 is satisfied.

Linkin Corporation is considering purchasing a new delivery truck. The truck has many advantages over the company’s current truck (not the least of which is that it runs). The new truck would cost $55,440. Because of the increased capacity, reduced maintenance costs, and increased fuel economy, the new truck is expected to generate cost savings of $8,400. At the end of 8 years, the company will sell the truck for an estimated $27,700. Traditionally the company has used a rule of thumb that a proposal should not be accepted unless it has a payback period that is less than 50% of the asset’s estimated useful life. Larry Newton, a new manager, has suggested that the company should not rely solely on the payback approach, but should also employ the net present value method when evaluating new projects. The company’s cost of capital is 8%.

Answers

The payback period of the investment is 6.6 years.

The net present value is $7,797.22.

The payback period calculates the amount of time it takes to recover the amount invested from the cumulative cashflows.

Payback period = Amount invested / cost saving

$55,440 / $8,400 = 6.6 years

Net present value is the present value of after-tax cash flows from an investment less the amount invested.  

NPV can be determined using a financial calculator

Cash flow in year 0 = $-55440

Cash flow in year 1 to 7 = $8,400

Cash flow in year 8 = $8400 + $27,700

I = 8%

NPV = $7,797.22

If the side of a square is increased by 25%, then by how much is its area increased?

Answers

Answer:

56.25%

Step-by-step explanation:

If a variable X changes by A% and another variable Y changes by B%, then overall net change when the two variables are multiplied is given by :

A + B + AB/100

If the change is “increase” it is positive & if the change is “decrease” it is negative.

In the given question, A = B = 25% ( Both positive as length increase )

And area = Side x Side

Applying our versatile relation :

Net increase in area = 25 + 25 + (25x25)/100 = 56.25%

--------------------

Bella's Expression: 0.75d

0.75: percent of original priced: original price0.75d: sale price

=============================================

Explanation:

The variable d stands for the original price. The store is offering a 25% sale, which means that Hasan will save 25% of the original price. This means 0.25d represents the amount he saves (aka the discount amount).

For instance, let's say d = 100 is the original price. 25% of this is 0.25d = 25 dollars. So if the book is originally $100, then he saves $25.

As you can probably guess, the 0.75 comes from 1 - 0.25 = 0.75; it indicates that if Hasan saves 25%, then he still has to pay the remaining 75%

Notice how d - 0.25d = 1d - 0.25d = (1-0.25)d = 0.75d which points to the sale price being 75% of the original price d.

So using disk method, the volume is given by:

The volume of the solid obtained by rotating the region bounded by the given curves about [tex]y = 1[/tex] is [tex]\frac{11\pi}{30} [/tex] cubic units.

Procedure - Determination of the volume of a solid of revolution

Let [tex]f(x) = 1[/tex], [tex]g(x) = x^{1/2}[/tex] and [tex]h(x) = x^{2}[/tex], both [tex]g(x) [/tex] and [tex]h(x)[/tex] have the following intersection points: [tex](x_{1}, y_{1}) = (0, 0)[/tex] and [tex](x_{2}, y_{2}) = (1,1)[/tex]. This means that the interval of x-coordinates for the solid of revolution is [tex]x \in [0, 1][/tex].

The integral formula for the volume of the solid of revolution ([tex]V[/tex]), in cubic units, is:

[tex]V = \pi \int\limits^{1}_{0} {[h(x)-f(x)]^{2}} \, dx - \pi \int\limits^{1}_{0} {[g(x)-f(x)]^{2}} \, dx [/tex] (1)

After substituting on each function and simplifying terms we get the following integral:

[tex]V = \pi \int\limits^{1}_{0} {(x^{2}-1)^{2}} \, dx - \pi \int\limits^{1}_{0} {(x^{1/2}-1)^{2}} \, dx [/tex]

[tex]V = \pi\left[\int\limits^{1}_{0} {x^{4}} \, dx - 2\int\limits^{1}_{0} {x^{2}} \, dx -\int\limits^{1}_{0} {x} \, dx + 2\int\limits^{1}_{0} {x^{1/2}} \, dx \right][/tex]

And the volume of the solid of revolution is:

[tex]V = \pi \cdot \left(\frac{1}{5}-\frac{2}{3} -\frac{1}{2}+\frac{4}{3} \right)[/tex]

[tex]V = \frac{11\pi}{30} [/tex]
