Answer:

y=8x/9

Step-by-step explanation:

Given that 8 euros were worth $9 and

24 euros were worth $27.

Let y represent the number of Euros and x no of dollars.

Given that the relation is of the form y = kx+C

When x=0 y =0,

i.e. C =0

Hence equation is of the form y = kx

Substitute x=8 and y =9

We get 9 = 8k

Or k =8/9

Hence relation is y=8x/9 is the relation between x and y.

WE can verify this for 27 dollars worth 24 euros.

24 =8/9(27) is true.

Thus equation is verified.

(3x^2 + 2x + 7X^3) + (10x^2 + 6x + 9)

Combine all the like terms.

There is only one term with X^3 so that stays the same.

Add 3X^2 and 10x^2 to get 13x^2.

Add 2x and 6x to get 8x.

There is only one term with a variable, so that also stays the same.

Now place them in order from highest exponent to lowest:

7x^3 + 13x^2 + 8x + 9

The answer is A.

x = - [tex]\frac{7}{4}[/tex] or x = 0

take out a common factor 2x

2x(4x + 7 ) = 0

equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

4x + 7 = 0 ⇒ x = - [tex]\frac{7}{4}[/tex]

The value of x is option C. 13.

The triangle proportionality theorem states that if a line is drawn inside the triangle which is parallel to any side of the given triangle, then the line intersects other two sides at two different points. Then the division of the other two sides of the triangle will be in the same ratio.

Given is a triangle ABC.

A line PQ is drawn which is parallel to the line BC.

We have to find the value of x, which is the length of AQ.

Using the triangle Proportionality theorem,

AP / PB = AQ / QC

Substituting the values,

6 / 12 = x / 26

Cross multiplying,

12x = 6 × 26

x = 156 / 12

x = 13

Hence the value of x is 13.

Answer:

[tex]y =\frac{1}{6} + 0.25x[/tex]

[tex]0 \leq x \leq23.33[/tex]

[tex]0 \leq y \leq 6[/tex]

Step-by-step explanation:

The machine always takes 10 minutes (or 1/6 hours) to warm up and performs each cycle in 15 minutes, or 0.25 hours.

The maximum amount of daily hours that the machine can work is 6 hours.

Therefore we can represent this situation by means of an equation of the form:

[tex]y =\frac{1}{6} + 0.25x[/tex]

Where

y = daily amount of hours the machine works.

x = number of daily cycles performed.

This equation is a linear function.  Because it has the form y = ax where a is a real number

The graph of this equation is shown in the attached image, where the gray shaded area represents the domain of the function.

The domain of the function is:

[tex]x\geq 0[/tex] (because you can not perform less than zero cycles a day)

[tex]x \leq23.33[/tex]. Because the machine can not exceed 6 hours per day, then it can not do more than 23.33 cycles.

So:

[tex]0 \leq x \leq23.33[/tex]

The range of the function is:

[tex]y \geq 0[/tex] (because you can not work less than 0 hours a day)

[tex]y \leq 6[/tex] (because the machine can not work more than 6 hours a day)

So

[tex]0 \leq y \leq 6[/tex]

Given

Sue wants to buy a video that costs $24.95.

She has $3 in her pocket

a piggy bank full of quarters x

Find out the inequality can be used to represent the number of quarters sue needs to buy the game.

To proof

As given in the question

Sue wants to buy a video that costs = $24.95.

She has $3

The value of quaters in the piggy bank = x

1 $ = 4 quaters

First convert $24.95 in the quaters form

=  4 × 24.95

= 99.8 quaters

convert $3 in the quaters form

= 3 × 4

= 12 quaters

The equation become in the form

[tex]12 + x \geq 99.8[/tex]

x = 87.8 quaters

quarters sue needs to buy the game is  87.8 quaters.

Answer:

Deposit each quarter = $342.68

Step-by-step explanation:

Formula use in this problem:

[tex] FV=C\times \left [ \frac{(1+i)^n-1}{i} \right ]\times (1+i) [/tex]

Where,  

          FV is future value, FV=$3000

C is cash flow quarterly( need to find),C=?

I is rate of interest ( divide by 4), i=[tex] \frac{0.08}{4}=0.02 [/tex]

N number of cash flow, n=8

Substitute all these values into formula to solve for C

[tex] 3000=C\times \left [ \frac{(1+0.02)^8-1}{0.02} \right ]\times (1+0.02) [/tex]

[tex] C=\frac{3000\times 0.02}{[(1+0.02)^8-1]\times (1+0.02)}[/tex]

So, C=$342.68

Final answer:

To achieve $3000 in 2 years in an account with 8% interest compounded quarterly, you should deposit $364.11 each quarter.

Explanation:

To find out how much you need to deposit each quarter to have $3000 in 2 years in an account that pays 8% interest compounded quarterly, you would use the future value of a series formula given by:

S = R [((1 + i)^n - 1) / i]

Where:

S = the future value of the series (in this case, $3000)

R = the regular deposit amount per period (what we're solving for)

i = the interest rate per period (8% per year or 0.08 divided by 4 for quarterly = 0.02)

n = the total number of compounds over the period (2 years * 4 quarters/year = 8 compounds)

Plugging in our values:

$3000 = R [((1 + 0.02)^8 - 1) / 0.02]

$3000 = R * [((1.02)^8 - 1) / 0.02]

$3000 = R * 8.2432

So, solving for R, we get:

R = $3000 / 8.2432 = $364.11

Therefore, to have $3000 in 2 years with an account that pays 8% interest compounded quarterly, you need to deposit $364.11 at the start of each quarter.

Each friend received 10 ounces of pears after Dillion divided the 3 1/3 pound bag among them.

First, we need to convert the weight of the pears from pounds and thirds to decimal form.

To do this, we divide the 3 1/3 pounds by 16 (since there are 16 ounces in a pound):

3 1/3 pounds = 3 * (1 + 1/3) pounds = 3.333 pounds

Now we know that each friend received 3.333 pounds / 5 friends = .6666 pounds of pears. To convert this decimal into something more understandable, multiply it by 16 since there are 16 ounces in a pound:

.6666 pounds * 16 = 10 ounces

So, each friend received 10 ounces of pears.

Answer: the answer is b 2,741 sorry im late

Solution :

Given that in the right triangle , ∠A=30° and AB = 12√3 .

As the figure is missing and its not clearly mentioned that AB is the base or hypotenuse of the right triangle. So two cases arises-

Case 1: AB is the base for ∠A of  the right triangle (as shown in figure 1).

As we know from the trigonometric ratio that, [tex]cos(\theta) = \frac{base}{hypotenuse}[/tex]

Here , AB is the base and AC is the hypotenuse , and ∠A=30°

[tex]\Rightarrow cos(30)=\frac{AB}{AC} \\\\\Rightarrow AC=\frac{AB}{cos(30)}[/tex]

The value of [tex]cos(30)=\frac{\sqrt{3} }{2}[/tex]

[tex]\Rightarrow AC=12\sqrt{3}\times\frac{2 }{\sqrt{3} }\\\\\Rightarrow AC=24[/tex]

Hence, AC is 24 unit long.

Case 2: AB is the hypotenuse for ∠A of  the right triangle (as shown in figure 2).

As we know from the trigonometric ratio that, [tex]cos(\theta) = \frac{base}{hypotenuse}[/tex]

Here , AB is the hypotenuse and AC is the base, and ∠A=30°

[tex]\Rightarrow cos(30)=\frac{AC}{AB} \\\\\Rightarrow AC=AB\timescos(30)[/tex]

The value of [tex]cos(30)=\frac{\sqrt{3} }{2}[/tex]

[tex]\Rightarrow AC=12\sqrt{3}\times\frac{\sqrt{3}}{2}\\\\\Rightarrow AC=18[/tex]

Hence, AC is 18 unit long.

Initial salary =  $50,000 .

Rate of raise = 5% each year.

Therefore, each next year salary would be 105% that is 1.05 times.

5% of 50,000 = 0.05 × 50000 = 2500.

Therefore raise is $2500 each year.

According to geometric sequence first term 50000 and common ratio 1.05.

Applying geometric sequence formula

[tex]a_n = ar^{n-1}[/tex]

1) [tex]a_n = 50000(1.05)^{n-1}[/tex]

2) In order to find salary in 5 years we need to plug n=5, we get

[tex]a_5 = 50000(1.05)^{5-1}= 50000(1.05)^4[/tex]

= 50000(1.21550625)

3) In order to find the total salary in 10 years we need to apply sum of 10 terms formula of a geometric sequence.

[tex]S_n = \frac{a(1-r^n}{1-r}[/tex]

Plugging n=10, a = 50000 and r= 1.05.

[tex]S_10 = \frac{50000(1-(1.05)^{10}}{1-1.05}[/tex]

[tex]S_10 = \frac{50000(0.050)^{10}}{0.05}[/tex]

= 628894.62678.
