Answer:33in

Answer:

$560.29

Step-by-step explanation:

To find the total price, first, find out how much of $519.99 is 7.75%

To do this convert %7.75 into a decimal [divide by 100]

7.75% = 0.0775

Now multiply 0.0775 by $519.99

519.99 x 0.0775 = 40.299225

Since 40.299225 is an amount of money, round it to the nearest hundreth in cents.

40.299225 = 40.30

Now add the sales tax and original price.

$40.30 + $519.99 = 560.29

So, the cost of the bicycle after sales tax is $560.29

Answer:

[tex]\frac{\sqrt[3]{5} }{3x}[/tex]

Step-by-step explanation:

Ok, let's do this step by step....

[tex]\sqrt[3]{\frac{10x^{5} }{54x^{8} } }[/tex]

Let's first simplify the x's:

[tex]\sqrt[3]{\frac{10}{54x^{3} } }[/tex]

Then we breakdown the 54 as 2 * 27 then simplify with the 10 above.

[tex]\sqrt[3]{\frac{10}{2 * 27x^{3} } } = \sqrt[3]{\frac{5}{27x^{3} } }[/tex]

Now, we can rewrite this as the following and solve the bottom part:

[tex]\frac{\sqrt[3]{5} }{\sqrt[3]{27x^{3} } } = \frac{\sqrt[3]{5} }{3 \sqrt[3]{x^{3} } } = \frac{\sqrt[3]{5} }{3x}[/tex]

The solution is

Step-by-step explanation:

The graph will be a straight line that starts at the origin and rises diagonally to the right with a slope of 2. The correct graph id graph 2

Since each light panel holds two light bulbs, the number of light bulbs, y, is directly proportional to the number of light panels, x. This means that as the number of light panels increases, the number of light bulbs will also increase in a linear manner.

The relationship can be represented by the equation:

y = 2x

Where y represents the number of light bulbs and x represents the number of light panels.

The graph representing the relationship between the number of light panels, x, and the number of light bulbs, y, will be a straight line.

In this case, the line will have a positive slope of 2 since each light panel holds two light bulbs. This means that for every increase of one unit in the number of light panels, the number of light bulbs will increase by two units.

The graph will pass through the origin (0, 0) since when there are no light panels (x = 0), there will be no light bulbs (y = 0).

As x increases, y will also increase in a linear manner. The line will extend indefinitely in the positive direction in both the x-axis and y-axis, indicating that the relationship continues without any upper limit.

Visually, the graph will be a straight line that starts at the origin and rises diagonally to the right with a slope of 2.

Answer:

The product of 2x + y and 5x – y + 3 is 10x^2+ 3xy + 6x - y^2 + 3y

Step-by-step explanation:

The product of the two expressions can be expressed mathematically as;

(2x +y) (5x -y +3)

To obtain the product of these expressions, we simply expand the brackets as follows;

2x(5x -y +3) + y(5x -y +3)

= 10x^2 - 2xy + 6x + 5xy - y^2 + 3y

= 10x^2- 2xy + 5xy + 6x - y^2 + 3y

= 10x^2+ 3xy + 6x - y^2 + 3y

The product of 2x + y and 5x – y + 3 is thus 10x^2+ 3xy + 6x - y^2 + 3y

Answer: 10x^2 +3xy +  6x + -1y^2 + 3y

[tex]0.5x-42.15>20[/tex]

Step-by-step explanation:

Let x represents the amount of Alicia’s paycheck.

Alicia set aside the other half to take her friends out to dinner. That means she took 0.5x with her for dinner.

She spent 42.15 on dinner and brought home more than 20.00.

So, the inequality will be :

[tex]0.5x-42.15>20[/tex]

Solving for x;

=> [tex]0.5x>20+42.15[/tex]

=> [tex]0.5x>62.15[/tex]

Final answer:

Logan can read 80 pages in 2 hours.

Explanation:

To find out how many pages Logan can read in 2 hours, we need to calculate the total number of minutes in 2 hours, which is 120 minutes. Then, we can multiply the rate at which Logan reads, which is 2/3 page per minute, by the total number of minutes to get the answer.

So, Logan can read:
(2/3) x 120 = 80 pages

Therefore, Logan can read 80 pages in 2 hours.

Answer:

Step-by-step explanation:

I take it that the base of the log is 4.

So the question can be written as

log_4 [(x+2)/(x + 3)] = -1

If you take the antilog of this, you get

(x + 2)/(x+3) = 4^-1 = 1/4

Now Cross Multiply

4*(x + 2) = 1*(x + 3)               Remove  the brackets on both sides

4x + 8 = x + 3                       subtract x from both sides.

4x - x + 8 = x - x + 3             Combine

3x + 8 = 3                             Subtract 8 from both sides

3x = 3 - 8                              Combine

3x = - 5                                 Divide by 3

x = - 5/3

The ratio of baseballs to the total number of balls in the storage room is 1:5. For every one baseball, there are five balls of any type.

We are looking for the ratio of baseballs to total balls. We find the total by adding the number of each type of balls: 10 (baseballs) + 4 (basketballs) + 12 (softballs) + 4 (soccer balls) + 20 (tennis balls) = 50 balls in total.

Now that we know the total, we can find the ratio of baseballs to the total amount of balls. There are 10 baseballs from a total of 50 balls. Thus, the ratio would be 10:50. Simplified, this ratio would be 1:5. This means for every one baseball, there are five balls of any type.

Answer:

For 3 people Kevin would need 90g of strawberry jelly, 6 sponge fingers, 315ml of custard and 135g of tinned fruit.

Step-by-step explanation:

To work this out you would need to work out how many ingredients would be needed for 1 person, so you would need to divide each ingredient amounts by 4. (For example for the strawberry jelly you would do 120÷4 which is 30).

Then, to work out how many ingredients would be needed for 3 people you would need to multiply the ingredient amounts by 3. (Like 30×3 is 90).

Daniel and his friends go to an amusement park to get on the fireball that costs $ 5 and the bumper cars cost $ 1 less. If Daniel climbs a total of 11 times and spends $ 50, how many times did he go up to each attraction?

costo de la bola de fuego: $5

costo de los coches de choque: 5 - 2 = $4

número de veces que montó bola de fuego = b

número de veces que montó de choque: m

b + m = 11 --> b = 11 - m

[tex]r=4\csc \theta \cot\theta[/tex]

Step-by-step explanation:

The given parametric equations are;

[tex]x=t^2[/tex]

[tex]y=2t[/tex]

We make t the subject in the second equation to get:

[tex]t=\frac{y}{2}[/tex]

We substitute into the first equation to get:

[tex]x=(\frac{y}{2})^2[/tex]

We use the relation:

[tex]x=r\cos \theta[/tex] and [tex]y=r\sin \theta[/tex]

[tex]r\cos \theta=(\frac{r\sin \theta}{2})^2[/tex]

[tex]r\cos \theta=\frac{r^2\sin^2 \theta}{4}[/tex]

[tex]r=4\csc \theta \cot\theta[/tex]

An equation is formed of two equal expressions. The polar form of parametric equations x=t² and y=2t is r = 4cosecθ cotθ.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The following parametric equation x=t² and y=2t in the form of a polar equation can be written as,

y=2t

t = y/2

Substituting the value of y from the second equation in the first,

x = (y/2)²

Using the basic relation we can write, the value of x and y as,

x = r cosθ

y = r sinθ

substitute the value of x and y,

r cosθ = [(r sinθ)/2]

r sinθ = (r²sin²θ)/4

r = 4cosecθ cotθ

Hence, the polar form of parametric equations x=t² and y=2t is r = 4cosecθ cotθ.
