Tax = 8%

Amount of tax = 8% of price of boots

[tex]Amount\ of\ tax = \frac{8}{100}*25\\Amount\ of tax=\frac{200}{100}\\Amount\ of\ tax=\$2[/tex]

Total = Price of boots + Tax amount

Answer:

x = 21 degrees

y = 66 degrees

Step-by-step explanation:

Supplementary angles sum 180 degrees and complementary angles sum 90 degrees.

The first two upper angles are supplementary since they complete half a turn of a circle.

The relation is

(3x+5)+(6x-14)=180.

Joining like terms

9x-9=180

Dividing by 9

x - 1= 20 =>

x = 21 degrees

The first and the last angle are the same because they are formed by two parallel lines to a common side, so

3x-5=y-8 or

y=3x+3 = 63+3 =>

y = 66 degrees

Scientific Notation is number between 1-10 multiplied by 10[tex]^{#}[/tex] (or e#) This has the 1-10 right but the other number incorrect.

The correct scientific notation is 3.4e+9.

Need to explanation why is 3.4 * 910 is not correct scientific notation.

Scientific notation means the longer value coded to short terms like 34000 to 3.4e+4.

Here 3.4*910 does not represent any thing because the correct manner for the scientific notation is ae + b. Where a = value and b =power to the 10.
so the correct scientific notation is 3.4e+9.

Thus, 3.4 * 910 is not correct scientific notation, the correct scientific notation is 3.4e+9.

Answer:

55%

Step-by-step explanation:

We have to divide the new price by the original price

4500/2900 = ca. 1.5517

Take away 100% from this answer and we get 0.5517 over the original price

This is the same as 55.17% can be rounded to 55%

To find the percent increase in the boat's price, subtract the original price from the selling price, divide by the original price, then multiply by 100 and round to the nearest whole number. The calculation shows about a 55% increase from the original price of $2900 to the selling price of $4500.

To calculate the percent increase, you would subtract the original price of the boat from the selling price and then divide by the original price to get the fraction of the increase. Finally, you multiply this fraction by 100 to convert it to a percentage. Using the given numbers: The original price is $2900, and the selling price is $4500.

When you round this to the nearest whole number, you get a percent increase of 55%.

Answer:

Step-by-step explanation:

Answer:

Yes, because x = 2 and y = 6 is a solution to the equation.

The point (2, 6) does lie on the graph of the equation y = 3x because when you substitute x = 2 and y = 6 into the equation, it holds true (6=3*2). Hence, yes, because x = 2 and y = 6 is a solution to the equation.

To determine if the point (2, 6) is on the graph of y = 3x, you would need to substitute the values of x and y into the equation and see if it holds true. In this case, if we substitute x = 2 and y = 6, we get 6 = 3*2, which simplifies to 6 = 6. This shows that the equation is true, therefore, the point (2, 6) lies on the graph of y = 3x. So the correct answer is C: Yes, because x = 2 and y = 6 is a solution to the equation.

Answer:

The speed of River's mom drove for 10 miles distance is 0.234 mph.

The speed of  River's mom drove for 25 miles is 10.234 mph.

Step-by-step explanation:

Given as :

The first distance cover by River's mom = 10 miles

The rate of speed = x mph

The second distance cover by river's mom = 25 miles

The rate of speed = x + 10 mph

The total driving time = 45 min

Now, According to question

[tex]Time = \frac{Distance}{Speed}[/tex]

So, [tex]45 =  \frac{10}{x}+\frac{25}{x+10}[/tex]

Now dividing by 5 on both side we get;

[tex]9=\frac{2}{x}+\frac{5}{x+10}\\\\9= \frac{2(x+10)+5x}{x(x+10)}\\\\9= \frac{2x+20+5x}{x^2+10x}\\\\9(x^2+10x)= 7x+20\\9x^2+90x-7x-20=0\\9x^2+83x-20=0[/tex]

Solving this quadratic equation we get;

[tex]x=\frac{-b\±\sqrt{4ac}}{2a}[/tex]

[tex]x=\frac{-83\±\sqrt{4\times9 \times 20}}{2\times 9}\\\\x= \frac{-83\±\sqrt{720}}{18}\\ \\x= \frac{-83+87.22}{18} \ \ \ or \ \ x = \frac{-83-87.22}{18}\\\\x= 0.234 \ \ \ or\ \ \ \ x= - 9.4567[/tex]

Since speed cannot be in negative hence we will consider x= 0.234

So, The speed for 10 miles distance = x = 0.234 mph

and The speed of 25 miles = x + 10 = 0.234 + 10 = 10.234 mph

Hence The speed of River's mom drove for 10 miles distance is 0.234 mph

and The speed of  River's mom drove for 25 miles is 10.234 mph  

The two lines in this system of equations are parallel

Step-by-step explanation:

Let us revise the relation between 2 lines

∵ The system of equation is

3x - 6y = -12 ⇒ (1)

x - 2y = 10 ⇒ (2)

To solve the system using the substitution method, find x in terms of y in equation (2)

∵ x - 2y = 10

- Add 2y to both sides

∴ x = 2y + 10 ⇒ (3)

Substitute x in equation (1) by equation (3)

∵ 3(2y + 10) - 6y = -12

- Simplify the left hand side

∴ 6y + 30 - 6y = -12

- Add like terms in the left hand side

∴ 30 = -12

∴ The left hand side ≠ the right hand side

∴ There is no solution for the system of equations

∴ The system of equations represents two parallel lines

Using substitution method, we can see the system of equation has no solution and graphically, the lines are parallel to each other and don't intersect.

To solve the system of equations using the substitution method, we can solve one equation for one variable and substitute it into the other equation.

Let's start by solving the second equation for x:

x - 2y = 10

x = 2y + 10

Now we substitute this expression for x in the first equation:

3x - 6y = -12

3(2y + 10) - 6y = -12

6y + 30 - 6y = -12

30 = -12

Since the equation 30 = -12 is not true, we have reached a contradiction. This means that the system of equations has no solution.

Regarding the two lines in this system of equations, we can observe that they are parallel and they don't intersect with one another.

Step-by-step explanation:

Answer:

The time taken by engine of the car to accelerate is 3.24 seconds

Step-by-step explanation:

Given as :

The mass of the car = 1200 kg

The Force applied by engine to accelerate = 10, 000 N

The change in velocity = [tex]v_2[/tex] -  [tex]v_1[/tex] = 27 m/s

Let The time taken by engine = t sec

And Let The acceleration = a  m/s²

Now,

∵ Force is define as the product of mass and acceleration

I.e F = mass × acceleration

or, F = 1200 × a

or, 10,000 =  1200 × a

∴ a = [tex]\frac{10,000}{1200}[/tex]   m/s²

I.e a = 8.33 m/s²

Now , Again

∵ Acceleration is define as the rate of change of velocity

I.e a = [tex]\dfrac{v_2-v_1}{t}[/tex]

or, a =  [tex]\dfrac{27-0}{t}[/tex]

Or, t =  [tex]\dfrac{27}{a}[/tex]

I.e t = [tex]\dfrac{27}{8.33}[/tex]

∴ t = 3.24 sec

So, The time taken = 3.24 seconds

Hence The time taken by engine of the car to accelerate is 3.24 seconds . Answer

Step-by-step explanation: Isolate the variable by dividing each side by facotrs that don't contain the variable.

Hope this helps you out! ☺

Answer:

m = 11

Step-by-step explanation:

To find m, we solve this equation:

2.50+ 1.50(m-1)=17.50

We subtract 2.50 from both sides:

1.50(m-1) = 15

Next we divide by 1.5 on both sides:

m - 1 = 10

Lastly we add one to both sides:

m = 11

Answer:

The answer is D

Step-by-step explanation:

∠C + ∠E = 180°(consecutive angles)

7x +11° + 7x + 1° = 180°

14x + 12° = 180°

14x = 168°

x = 12°

∠E = 7x + 1°

= 7(12°) + 1

= 85°

The measure of ∠E is 85 degrees

To calculate the measure of E, we start by calculating the value of x using:

∠C + ∠E = 180° (consecutive angles of cyclic quadrilateral)

So, we have:

7x +11° + 7x + 1° = 180°

Evaluate the like terms

14x + 12° = 180°

Subtract 12 from both sides

14x = 168°

Divide both sides by 14

x = 12°

Recall that:

∠E = 7x + 1°

Substitute 12 for x

∠E = 7(12°) + 1

Evaluate

∠E = 85°

Hence, the measure of ∠E is 85 degrees

Final answer:

To find the value of k that makes (x+3) a factor of the function f(x)=3x^3-2x+k, substitute x=-3 into the equation, leading to the solution k=75.

Explanation:

The question asks for the value of k that makes (x+3) a factor of the function f(x)=3x³-2x+k. To solve this, we use the fact that if (x+3) is a factor of f(x), then f(-3)=0. Therefore, we substitute x=-3 into the equation and solve for k.

Substituting x=-3 into f(x)=3x³-2x+k gives:

f(-3) = 3(-3)³- 2(-3) + k = -81 + 6 + k

Since f(-3)=0, we have -75 + k = 0

Thus, k = 75

This computation shows that the value of k that makes (x+3) a factor of the given function is 75.

The answer is v= -8x/-xy+9

Here is the step by step process (This is going to be long):

Multiply both sides by vx

2.  9v+8x+−vxy=vxy+−vxy

−vxy+9v+8x=0

Add -vxy to both sides

3.  −vxy+9v+8x+−8x=0+−8x

−vxy+9v=−8x

Add -8x to both sides

4.  v(−xy+9)=−8x

Factor out the variable v

5.  v(-xy+9)/-xy+9 = -8x/-xy+9

v = -8x/-xy+9

Divide both sides by -xy+9
