Given:

Price of golf after tax = $460

Rate of sales tax = 9%

To find:

The amount of tax.

Solution:

Let x be the price of golf before tax.

According to the question,

Price of golf after tax = Price of golf before tax + tax

[tex]460=x+\dfrac{9}{100}x[/tex]

[tex]460=x+0.09x[/tex]

[tex]460=1.09x[/tex]

Divide both sides by 1.09.

[tex]\dfrac{460}{1.09}=x[/tex]

[tex]422.01835=x[/tex]

[tex]x\approx 422[/tex]

So, price of golf before tax is $422.

Now,

[tex]tax = \dfrac{9}{100}x[/tex]

[tex]tax = \dfrac{9}{100}(422)[/tex]

[tex]tax =\dfrac{3798}{100}[/tex]

[tex]tax=37.98[/tex]

Therefore, the amount of tax is $37.98.

This can be expressed in this form:

1/2x - 18.

Answer:

1 ≥ t ≤ 3

Step-by-step explanation:

Given

h(t) = -16t² + 64t + 4

Required

Determine the interval which the bar is at a height greater than or equal to 52ft

This implies that

h(t) ≥ 52

Substitute -16t² + 64t + 4 for h(t)

-16t² + 64t + 4 ≥ 52

Collect like terms

-16t² + 64t + 4 - 52 ≥ 0

-16t² + 64t - 48 ≥ 0

Divide through by 16

-t² + 4t - 3 ≥ 0

Multiply through by -1

t² - 4t + 3 ≤ 0

t² - 3t - t + 3 ≤ 0

t(t - 3) -1(t - 3) ≤ 0

(t - 1)(t - 3) ≤ 0

t - 1 ≤ 0 or t - 3 ≤ 0

t ≤ 1 or t ≤ 3

Rewrite as:

1 ≥ t or t ≤ 3

Combine inequality

1 ≥ t ≤ 3

Answer:

50

Step-by-step explanation:

Answer:

∠ 2 = 50°

Step-by-step explanation:

5x + 55 and 2x + 100 are corresponding angles and are congruent, thus

5x + 55 = 2x + 100 ( subtract 2x from both sides )

3x + 55 = 100 ( subtract 55 from both sides )

3x = 45 ( divide both sides by 3 )

x = 15

Then

5x + 55 = 5(15) + 55 = 75 + 55 = 130°

5x + 55 and ∠ 2 are adjacent angles and are supplementary, thus

∠ 2 = 180° - 130° = 50°

Answer:

The measure of the indicated exterior angle is 110°

Step-by-step explanation:

Let us revise the rule of the exterior angle

In a triangle, the measure of an exterior angle at a vertex of the triangle equals the sum of the measures of the two opposite interior angles to this vertex.

We will use this rule to solve the question

∵ The ladder, the house, and the ground formed a right triangle

∵ The ladder's angle with the ground facing away from the house is

   an exterior angle of the triangle

∵ The angles of measures 90° and 20° are its opposite interior angles

→ By using the rule above

∴ The measure of the exterior angle = 90° + 20°

∴ The measure of the exterior angle = 110°

∴ The measure of the ladder's angle with the ground facing away

   from the house is 110°

∴ The measure of the indicated exterior angle is 110°

Answer:

i think that the answer is the first equation

Step-by-step explanation:

The equation of the line passing through the points (0, 3) and (6, 11) is:

y = (4/3)x + 3.

Option C is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

To find the equation of the line passing through the points (0, 3) and (6, 11).

We can use the slope-intercept form of a linear equation,

which is y = mx + b, where m is the slope of the line and b is the y-intercept.

First, we can find the slope of the line by using the formula:

[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]

where

[tex](x_1, y_1) = (0, 3)\\(x_2, y_2) = (6, 11).[/tex]

So,

m = (11 - 3) / (6 - 0) = 8/6 = 4/3

The slope of the line is 4/3.

Next,

We can use the point-slope form of a linear equation to write the equation of the line in terms of one of the points and the slope:

[tex]y - y_1 = m(x - x_1)[/tex]

Choosing the point (0, 3), we get:

y - 3 = (4/3)(x - 0)

Simplifying and solving for y, we get:

y = (4/3)x + 3

Therefore,

The equation of the line passing through the points (0, 3) and (6, 11) is:

y = (4/3)x + 3.

trust me i just did it

Step-by-step explanation:

Answer:

The answer to this depends on the accuracy of the way this is transcribed.  If the value on the left side of the equals sign is indeed x, then it would be a rational equation.  If it is meant to be another scalar value though, then this would be a quadratic equation.

Step-by-step explanation:

This depends on the what is on the other side of the equals sign.  If it is a scalar value, then you are guaranteed a proper quadratic equation.  In the example given though:

[tex]x = ax^2 + bx + c[/tex]

This is not actually true.  In this example, we can divide both sides by x, giving us a very different equation:

[tex]x = ax^2 + bx + c\\1 = ax + b + c/x\\ax + c/x = 1b[/tex]

and this equation actually a rational one.

Answer:

a) If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords?

No he would not

b) How much will he have left over or how much more will he need?

= He would have 144 inches left over.

Step-by-step explanation:

The sword maker in the cove ordered a special tape to wrap the sword handles with. He knew each sword would need 48 inches of tape. If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords? How much will he have left over or how much more will he need?

From the above question, each sword would need 48 inches of tape

He would need to wrap 28 swords, hence:

1 swords = 48 inches

28 swords = x

x = 28 × 48 inches

= 1344 inches of tapes

Therefore to cover each sword he would need a total of 1344 inches of tape.

He ordered 100 feet of tape

We convert 100 feet to inches

1 foot = 12 inches

100 feet = x

x = 100 × 12 inches

x = 1200 inches

Hence, he ordered 1200 inches of tape.

a) If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords?

100 feet = 1200 inches of tapes

To wrap 28 swords he would need 1344 inches of tape hence, he would not have enough tape to wrap 28 swords.

b) How much will he have left over or how much more will he need?

= 1344 inches - 1200 inches

= 144 inches

He would have 144 inches left over.

Complex numbers are written in the form x + iy

Given the complex numbers expressed as:

z1 = 8 - i

z2 = -9 + 2i
