The number of more workers required that the work will finish in 24 days will be equal to 3 workers.

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

12 workers can finish the work in 30 days.

Let the number of more men be x that the work will be finished in 24 days.

Use the man-days concept.

M₁ D₁ = M₂D₂

Here, M₁ and M₂ are the numbers of men, and D₁ and D₂ are the numbers of days.

12 × 30 = x × 24

x = (12 × 30)/24

x = 15

So, the number of extra men is,

15 - 12 = 3 workers.

Answer:

6hrs = 15 miles

2hrs = 15 miles

Step-by-step explanation:

The length vector is 1. So the sketch vector field f is given below. So the option a is correct.

In the given question, the vector field F by drawing a diagram like this figure.

The given vector field F is:

F(x, y) = (yi + xj)/√(x^2 + y^2)

We can write the vector field as:

F(x, y) = yi/√(x^2 + y^2) + xj/√(x^2 + y^2)

Here

F(x, y) = [y/√(x^2 + y^2)]^2 + [x/√(x^2 + y^2)]^2

F(x, y) = y^2/(x^2 + y^2) + x^2/(x^2 + y^2)

F(x, y) = (y^2+ x^2)/(x^2 + y^2)

F(x, y) = 1

F(0, y) = y/|y| = ±1

F(x, 0) = x/|x| = ±1

So the length vector is 1.

So the sketch vector field f is given below:

The bicycle is moving at a speed of 14,356 meters per hour.

Here, we are given that the wheel of a bicycle is spinning at the rate of 150 revolutions per minute.

The diameter of the wheel is 20 inches

⇒ radius = 10 inches

⇒ circumference of the wheel = 2 × π × 10

= 20π

Thus, the wheel will cover a distance of (20π × 150) inches in a minute

= 300π

now, we know that 1 inch = 0.254 meters

⇒ 300π inches = 300π × 0.254

= 76.2π

Thus, the bicycle covers 76.2π meters in a minute

⇒ it'll cover 76.2π × 60 meters in an hour

= 4572π

= 4572 × 3.14

= 14,356.08

Thus, the bicycle is moving at a speed of 14,356 meters per hour.

Answer:9.9

Step-by-step explanation:

We know that pythagorean Theorem is a^2+b^2=c^2

Using this, and A & B we can plug them in

We get 49+49=c^2

98=c^2

we can square root both sides to get

sqrt98=c^2

or 9.9(rounded to the nearest 10th)

Answer:

c = 9.9 to the nearest tenth

Step-by-step explanation:

Pythagoras theorem = c² = a² + b²

a= 7, b = 7, c =?

c² = 7² + 7²

c² = 49 + 49

c² = 98

c =√98

c = 9.8995

The extent to which the researcher can refer that findings with a sample from which it was drawn is referred to as generalizability.

Generalizability refers to the ability to extrapolate study findings from a sample to the entire population. It also refers to the capacity to apply findings from one study to a similar environment in a different investigation.

Generalizability and transferability are two research traits that are related. When considering generalizability in research, there are two features or dimensions to consider: generalizability as it relates to the specific population on which the research is conducted, and generalizability on a global scale.

Such studies will be easier to generalize if the researcher uses adequate sampling approaches, sample sizes, and exact processes.

In general, a study has strong generalizability when the findings apply to a wide range of persons or situations. The study has weak generalizability if the results can only be applied to a subset of the population or in a very specific circumstance.

Although part of your question is missing, you might be referring to this full question: If the 1st person saves 1/4 of total, 2nd person saves 2/3 of total, and 3rd person saves 1/10, which fraction left to pay for the birthday party?

The fraction left to pay for the birthday party is 17/30.

The calculation is as follows:

1 * 1/4 = 1/4 … (1)

1/4 * 2/3 = 2/12 … (2)

2/12 * 1/10 = 2/120 … (3)

Fraction left to pay:

= 1 - (1/4 + 2/12 + 2/120)

= 1 - (30/120 + 20/120 + 2/120)

= 1 - (52/120)

= 1 - 13/30

= 30/30 - 13/30

Thus, the fraction left to pay for the birthday party is 17/30.

The area of the sector of a circle  is 28π square miles

The area of a sector of a circle is equal to the area of the circle multiplied by the ratio of the central angle to the full circumference. Therefore, the area of the sector of a circle with a radius of 6 miles formed by a central angle of 2.8 radians is equal to the area of the circle multiplied by the ratio of 2.8 radians to 2π radians (or the circumference of the circle). This means that the area of the sector is equal to 6^2π * 2.8/2π = 28π square miles. In other words, the area of the sector of a circle with a radius of 6 miles formed by a central angle of 2.8 radians is equal to 28π square miles. To visualize this, imagine a pizza slice with a radius of 6 miles. The area of the pizza slice is equal to 28π square miles. The area of the sector is the same as the area of the pizza slice. Therefore, the area of the sector of a circle with radius of 6 miles formed by a central angle of 2.8 radians is equal to 28π square miles.

The average rate of change of a function is said to be a measure of how much the function changed per unit The average rate of change is -100/11

The average rate of change of a function is said to be a measure of how much the function changed per unit, on average, over that interval. It is also said to be derived from the slope of the straight line connecting the interval's endpoints on the function's graph

f(x) over an interval [x1,x2] is given by:

average rate of change = change in y/change in x

= f(x2) − f(x1) / x2−x1

With f(x) = 1/x over [1, 11]

average rate of change = f(11) − f(1) / 11−1

average rate of change = (1/11 − 1) / 10

average rate of change = (−10/11 / 10

Think of a rectangle. The formula for its volume is simple [tex](base)(width)(height)[/tex]. In this case, base and width are [tex]\pi r^2[/tex], and the height is simply [tex]h[/tex].

Knowing this information, we can solve for the volume:

Diameter = 6 m . Radius is half of the diameter. So Radius, r, = 3 m.

Height = 7 m.

The value of a = 2x and b = x + 3. Which expression is equivalent to a - b?

Answer:

Step-by-step explanation:

In order to answer this question, we need to know what PEMDAS stands for.

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

Now using this order, we can solve.

There isn't any parenthesis.

There is an exponent, [tex]5^{3}[/tex].

Let's solve this.

5 × 5 × 5 = 125

Our equation now looks like this:

125 + 28 ÷ 7 - 1

There isn't any multiplication for us to solve.

There is division.

28 ÷ 7 = 4

Now our equation looks like this:

125 + 4 - 1

Now it's time for addition.

125 + 4 = 129

Now our equation looks like this:

129 - 1

Now all we need to do is subtraction.

129 - 1 = 128

The final answer is 128.

The domain and range is calculated to be

domain { x | 0 ≤ x ≤ 12 }

range (3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 }

The situation described has the following information deduced form the problem

a parking garage that operates from 7:00 a.m. to 7:00 p.m.

from  7:00 a.m. to 7:00 p.m = 12 hours

hence form 0 to 12 is the domain

and charges $3 for the first hour and. $2 for each additional hour or part of an hour of parking

this means that the y intercept is 3 and the slope is 2, hence the equation of the line is

y = 2x + 3

The range is calculated as follows, since 11.59 is counted as 12 we take 11

at x = 0, y = 2 * 0 + 3 = 3

at x = 11, y = 2 * 11 + 3 = 25
