Office Bargains sells 150 pens for $7.50. What is the price per pen? $ per pen

Answer:

50 / 122

Step-by-step explanation:

let

female left handed students = x

female right handed students = 5x

male left handed students = y

male right handed students = 9y

according to the question,

x + y = 18 (1)

9y + 5x = 122 (2)

from eq. (1)

x = 18 - y

substituting the value of x in eq. (2)

9y + 5(18 - y) = 122

9y + 90 - 5y = 122

4y = 32

thus, y = 8

x = 10

the probability of selecting a female right handed student at random is:

50 / 122

Alma's total intake in a month is 0.0738 mol.

What is weight ?

the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force.

To calculate the number of moles of ascorbic acid, we need to know its molecular weight. The molecular weight of ascorbic acid (C6H12O6) is approximately 176 g/mol.

Therefore, 13.00 g of ascorbic acid is equal to 13.00 g / 176 g/mol = 0.0738 mol.

So, Alma's total intake in a month is 0.0738 mol.

The total intake of ascorbic acid in her in a month is 0.0738 mol prescribed by her doctor.

A thing's weight is the amount of force that gravity applies to it. In many widely used textbooks, the term "weight" refers to the gravitational force acting on the object. Weight is sometimes referred to as a scalar quantity that gauges the strength of the gravitational pull.

To calculate the number of moles, we need to know the ascorbic acid's molecular weight. The molecular weight of ascorbic acid (C6H12O6) is about 176 g/mol.

This indicates that 13.00 g of ascorbic acid divided by 176 g/mol equals 0.0738 mol of ascorbic acid.

Therefore, Alma's total monthly intake is 0.0738 mol.

The factored form makes it easiest to see the zeros of the function, as they correspond to the roots (x-intercepts) of the equation. In this form, the zeros are x=4 and x=6.

        (x-4) = 0 or (x-6) = 0

        x = 4 or x = 6

These values correspond to the x-intercepts, or zeros, of the function.

The zeros of a function are the values of x where the function intersects the x-axis, or where the value of the function is equal to zero. In a factored form, each factor is equal to zero at specific values of x. These values correspond to the x-intercepts of the function, which are the zeros.

By setting each factor equal to zero and solving for x, we find the x-intercepts of the function, which are the zeros. This is why the factored form makes it easiest to see the zeros of a function.

The probability that the pizza delivery time is more than 45 minutes on a given day is 0.4615..

To calculate the probability, we need to find the area under the uniform distribution curve from 45 minutes to the maximum delivery time of 75 minutes.

The formula for a uniform distribution is:

f(x) = 1/(b-a)

where a is the minimum delivery time of 10 minutes and b is the maximum delivery time of 75 minutes.

The probability of a delivery time being greater than 45 minutes is:

P(X > 45) = 1 - P(X ≤ 45) = 1 - (45 - 10)/(75 - 10) = 1 - (35/65) = 1 - 0.53846 = 0.46154

Round off to four decimal places.

P(X > 45) = 0.4615

So the probability that the pizza delivery time is more than 45 minutes on a given day is 0.4615.

''Murphy charges $10 more than Nicki to rake leaves in a yard for 4 hours.''

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Murphy charges a $15 service fee and $10 per hour to rake leaves in a yard.

And, The equation y = 5x+25 represents the amount Nicki charges in dollars for x hours of leaf raking per yard.

Now, The equation to represents the amount Murphy charges in dollars for x hours of leaf raking per yard is,

⇒ y = 10x + 15

And, The equation represents the amount Nicki charges in dollars for x hours of leaf raking per yard is,

⇒ y = 5x + 25

Now, For 2 hours;

The amount Murphy charges in dollars for 2 hours of leaf raking per yard is,

⇒ y = 10x + 15

⇒ y = 10×2 + 15

⇒ y = 20 + 15

⇒ y = $35

And, the amount Nicki charges in dollars for 2 hours of leaf raking per yard is,

⇒ y = 5x + 25

⇒ y = 5×2 + 25

⇒ y = 10 + 25

⇒ y = 35

Thus, Nicki charges is equal to the Murphy to rake leaves in a yard for 2 hours.

Now, For 4 hours;

The amount Murphy charges in dollars for 4 hours of leaf raking per yard is,

⇒ y = 10x + 15

⇒ y = 10×4 + 15

⇒ y = 40 + 15

⇒ y = $55

And, the amount Nicki charges in dollars for 4 hours of leaf raking per yard is,

⇒ y = 5x + 25

⇒ y = 5×4 + 25

⇒ y = 20 + 25

⇒ y = 45

Thus, Murphy charges $10 more than Nicki to rake leaves in a yard for 4 hours.

Answer: -10 degrees

Step-by-step explanation:

    If it drops 6 degrees per hour, then we can use multiplication to see how much it will have dropped after 3 hours:

          6 degrees * 3 hours = 18 degrees

     If the temperature is 8 degrees, and it drops 18 degrees, we will subtract:

         8 degrees - 18 degrees = -10 degrees

Answer:

26 degrees.

Step-by-step explanation:

The temperature will increase by 6 degrees per hour for three hours, so the final temperature after three hours will be:

[tex]\sf:\implies{8 + 6 \times 3 = 8 + 18 = 26 }[/tex]

Making implied premises explicit is important for ensuring clarity, transparency, evidence-based arguments, logical rigor, better communication, and improved decision making

There are several reasons to make implied premises explicit:

Clarity: Implied premises can sometimes be ambiguous or unclear. Making them explicit can help to avoid confusion and ensure that all parties involved understand the argument.

Transparency: Implied premises can hide the underlying assumptions of an argument. Making them explicit can increase the transparency of the argument and allow for greater scrutiny of its validity.

Evidence: Implied premises are often based on unstated assumptions or beliefs. Making them explicit can allow for the introduction of evidence to support or challenge these assumptions.

Logical rigor: Implied premises can make an argument appear stronger than it actually is. By making them explicit, the argument can be evaluated more rigorously and any weaknesses or gaps can be identified.

Better communication: Implied premises can be difficult to detect, especially in complex arguments. By making them explicit, the argument becomes easier to follow and understand, facilitating better communication between the parties involved.

Improved decision making: When the premises of an argument are made explicit, it becomes easier to weigh the pros and cons and make informed decisions based on the evidence presented.

Speed of the slower plane = 350 miles/hour

Relative speed is the speed of a moving body in relation to another. When two bodies are moving in the same direction, their difference is used to calculate their relative speed. When two bodies are moving in opposite directions, however, the relative speed is derived by summing their speeds.

Given,

Two planes heading opposite directions

After 2 hours the planes are 1500 miles apart.

Speeds of the planes differ by 50 mph

Let the speed of slower plane be x

then speed of faster plane = x + 50

Since, plane are moving in opposite directions

Relative speed = x + x + 50

Speed = distance /time

x + x + 50 = 1500/2

2x + 50 = 750

2x = 750 - 50

x = 700/2

x = 350 miles/hour

The Trapezoid is a 4 sided polygon. Two sides of the shape are parallel to each other and they are termed as the bases of the trapezoid. The non-parallel sides are known as the legs or lateral sides of a trapezoid.

There are three types of trapezoids , and those are given below:

a) Isosceles Trapezoid

b) Scalene Trapezoid

c) Right Trapezoid

The area of the Trapezoid is given by

Area of Trapezoid = ( ( a + b ) h ) / 2

where , a = shorter base of trapezium

b = longer base of trapezium

h = height of trapezium

Given data ,

Let the area of the trapezoid be represented as A

Now , the shorter base of the trapezoid a = 205 miles

The longer base of the trapezoid b = 511 miles

The height of the trapezoid h = 309 miles
