Paul is a carpenter and earns $21.50 per hour. Last week Paul worked 40 hours, what is
Paul's gross pay?

Answers

Answer: $860 this week.

Step-by-step explanation:

Paul worked 40 hours this week, and makes 21.50 dollars an hour. Gross pay means the amount of money paid before taxes.

So we don't need to calculate any taxes, which means all we need to do is multiply 21.50 by 40 hours, since he makes 21.50 an hour, and he worked 40 hours.

The value of x in this geometric sequence is equal to √2.

How to calculate the nth term of a geometric sequence?

In Mathematics, the nth term of a geometric sequence can be calculated by using this mathematical expression:

aₙ = a₁rⁿ⁻¹

Where:

aₙ is the nth term of a geometric sequence.r represents the common ratio.a₁ represents the first term of a geometric sequence.

For this exercise, we would formulate an equation from the common ratio of this geometric sequence as follows:

r = a₂/a₁ = a₃/a₁

Substituting the given parameters into the common ratio formula, we have;

1/√X + 1 = √x - 1/1

Next, we would take the square of both sides, we have:

1/x + 1 = x - 1/1

Cross-multiplying, we have:

(x + 1)(x - 1) = 1

x² - x + x - 1 = 1

x² - 1 = 1

Adding 1 to both sides, we have:

x² - 1 + 1 = 1 + 1

x² = 1 + 1

x² = 2

x = √2

The area of the composite figure is 58. 71 square units.

How to determine the area

It is important to note that the area of the composite figure is given as;

Area of a rectangle + area of a semi circle

The formula for area of a rectangle is expressed as;

Area = lw

Where;

l is the length of the rectanglew is the width of the rectangle

Now, let's substitute the values, we have;

Area = 6 × 9

Area = 54 square units

The formula for area of a semicircle is expressed as;

Area = πr²/2

Where;

pi = 3. 14r is the radius of the semi circle

Given diameter = 6, radius = 6/2 = 3

Substitute the value

Area = 3. 14(3)/2

Area = 4. 71 square units

But area of the composite figure = 54 + 4. 71 = 58. 71 square units.

Which equation represents the same proportional relationship as the graph? On a coordinate plane, a line goes through points (0, 0), (5, 3), (10, 6). Group of answer choices y = five-thirds x x y = three-fifths y = three-fifths x x y = five-thirds

Answers

Based on the line and the points that it goes through, the equation with the same proportional relationship as the graph is y = three-fifths x.

How to find the relationship of the graph?

To find the relationship of the points on the line in the coordinate plane, you need to find the slope of the line. The slope can be found by the formula:

= Change in y / Change in x

Solving for the slope gives:

= (3 - 0) / (5 - 0)

= 3 / 5

For equations to be proportional, they need to have the same slope. With the slope of the line being 3/5, the equation that would have the same proportional relationship is:

Computer programs are one of the intangible components of software, which also includes documentation and other components.The version of a computer program that humans can read is called the source code. Source code must be run by another program because computers can only execute their native machine instructions. Consequently, source code can be transformed into machine instructions using the language's compiler. (Programs written in machine language are translated using an assembler.)

Answers

The properties of equality used in the equation are subtraction properties and multiplication properties of equality

How to determine the properties of equality applied in solving the equation?

The complete question is added at the end of the solution

From the complete question, the equation is given as:

(1/3d + 4 = 28)

Start by removing the bracket in the given equation

So, we have

1/3d + 4 = 28

Next, we continue by applying the subtraction properties of equality

This means that we subtract 4 from both sides of the equation.

So, we have:

1/3d + 4 - 4= 28 - 4

Evaluate the difference in the above equation

So, we have

1/3d = 24

Next, we continue by applying the product properties of equality

This means that we multiply both sides of the equation by 3

So, we have:

3 * 1/3d = 24 * 3

Evaluate the products in the above equation

So, we have

d = 72

Answers

After 18 hours the remaining quantity of the radioactive sample will be (A) 4.68 grams.

What are mathematical operations?An operation, also known as an "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the operations that are most frequently studied.

So, original radioactive substance = 3000 grams.

Half-life = 3 hours

So, a number of half-lives in 18 hours:

18/3 = 6

Then, after 18 hours:

1/(2)⁶ ⇒ 1/64 × 300 = 4.6875 grams

Therefore, after 18 hours the remaining quantity of the radioactive sample will be (A) 4.68 grams.

Answers

The balloon's vertical distance above the ground is equal to 633.7 feet

What is angle of depression?
The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line.

Given data ,

we have Angle of depression = 35°

Base distance D = 905 ft

Let the vertical distance be H

To calculate the vertical distance H of the balloon above the ground , we use the angle of depression and the base distance.

Therefore , using the trigonometric identities ,

sin = Opposite / Hypotenuse

cos = Adjacent / Hypotenuse

tan = Opposite / Adjacent

So , tan  Ф = tan 35°

                  = H / D

      tan 35°= H / 905

H = tan 35° x 905 ft

H = 0.7002075 x 905

H = 633.7 ft

Hence ,  vertical distance is equal to 633.7 ft

if r and s are integers and an expression of the form (x − r)(x − s) is multiplied out, a quadratic polynomial with integer coefficients is obtained. for instance, (x − 2)(x − 7)

Answers

The quadratic expression when ( x - 2) ( x - 7 ) is multiplied is x² - 9x + 14.

A polynomial of degree two or a quadratic polynomial that has two as the highest exponent of the variable. A quadratic polynomial will typically have the following form: p(x): ax² + bx + c, a ≠ 0.

A coefficient is a multiplicative factor in a polynomial term, a series term, or an expression; it often has the form of a number but can also take the form of any expression.

When an expression ( x - r )( x - s ) is multiplied, where r and s are integers, we obtain a quadratic polynomial.

Therefore, when ( x - 2 )( x - 7 ) is multiplied we get:

( x - 2 )( x - 7 ) = x( x - 7 ) - 2( x - 7 )

( x - 2 )( x - 7 ) = x² - 7x - 2x + 14
