What is meant by division?

One of the four fundamental operations of arithmetic, or how to mix numbers to create new ones, is division. Addition, subtraction, and multiplication are the other operations.

In its most basic form, the division of two natural numbers involves counting the instances in which one number is contained inside another, among other possible applications. It is not required that this number be an integer. When two natural numbers are divided with a remainder, or in the Euclidean method, the result is an integer quotient, or the number of times the second number is entirely included in the first, and a remainder, or the portion of the first number.

1) 2.25/2.5=0.9

2) 35/0.05=700

3) 45/0.15=300

4) 630.21/0.07=9003

−4x+4y=−8

4x−6y=16

Answers

Answer:

(- 2, - 4 )

Step-by-step explanation:

- 4x + 4y = - 8 → (1)

4x - 6y = 16 → (2)

adding (1) and (2) term by term will eliminate x

0 - 2y = 8

- 2y = 8 ( divide both sides by - 2 )

y = - 4

substitute y = - 4 into either of the 2 equations and solve for x

substituting into (2)

4x - 6(- 4) = 16

4x + 24 = 16 ( subtract 24 from both sides )

4x = - 8 ( divide both sides by 4 )

x = - 2

Arithmetic is an elementary a part of arithmetic that consists of the study of the properties of the normal operations on numbers—addition, subtraction, multiplication, division, mathematical operation, and extraction of roots.

Main body:

Let 'y' stand for the speed of the wind and 'x' stand for the speed of Santa. We will use the general equation (distance)=(rate)(time) to write two equations from the given information:

With the wind:

35=(x+y)(5)                -------(1)

Against the wind:

35=(x-y)(7)                 --------(2)

using equation 1  ,we have

Find the value of that maximize the profit, und determine the correponding price and total profit for thi level of production

Answers

The value of that maximize the profit, und determine the corresponding price and total profit for the level of production is $52,500

Given,

Suppose that the demand equation for a monopolist is p=100−.02x and the cost function is C(x)=20x+10,000. Find the value of x that maximizes the profit and determine the corresponding price and total profit for this level of production.

Here we need to find the value of that maximize the profit.

As per the Monopolist maximizes profit by setting marginal costs (MC) equal to marginal revenue (MR).

Here the Marginal revenue is the first partial derivative of Total revenue (TR) function.

And the total revenue is the quantity (X) times price (P):

TR = P⋅X

=> (100−0.01X) X

=> 100X−0.02X

Then we get get marginal cost, take the partial derivative of the cost function with respect to x:

=> MC=∂c(X)/∂X:50

=> MR=MC/100−0.02X=50/100−50

=> 0.02X

=> 2500units

Then the price of X, plug in the value of x in the inverse demand function and solve for price:

=> P=100−0.01(2500)=$75

And the profit is the difference between Total revenue and Total costs:

=> ∏=TR−TC/TR = P⋅X

=> $75 × 2500 = $187,500

Finally, the total costs, plug in the value of x in the total cost function:

=> TC = 50(2500)+10,000

=> $135,000

=> ∏ = $187,500−$135,000

=> $52,500

Answers

The probability that at least one graduate out of the five who were picked at random obtains a job in their chosen area within a year of graduation is 93.96%.

Explain the term binomial probability?A binomial experiment can have two possible outcomes: success or failure, and the term "binomial probability" refers to the likelihood of obtaining precisely x successes upon n repeated but independent trials. The probability of success on a single try is p, and the formula for the binomial probability is as follows:P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

Let X represent a random variable which represents the proportion all school graduates who secure employment in their profession of choice within a year of graduation:

With a binomial distribution,

X has a n = 5 and a p value of 0.57.

n = number of trial.

p = probability of success

x = number of success.

A binomial distribution's probability mass function is provided by:

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

The likelihood that at least one gets employment in their field of choice within a year after graduation:

P(X ≥ 1) = 1 - P(X < 1)

P(X ≥ 1) = 1 - P(X = 0)

P(X ≥ 1) = 1 - ⁵C₀ . (0.57)⁰ . (0.43)⁹⁻⁰

P(X ≥ 1) = 1 - 0.603

P(X ≥ 1) = 0.9396

P(X ≥ 1) = 93.96%

Thus, the probability that at least one graduate out of the five who were picked at random obtains a job in their chosen area within a year of graduation is 93.96%.

Answers

The total displacement in km and vector form in the form of i and j is 35.8 a[x] km + 0 a[y] km.

According to the question,

We have the following information:

A cyclist rode his bike for 169 min at an average velocity of 3. 53 m/s on a bearing of 450.

Now, we know that the following formula is used to find the velocity:

Velocity = displacement/time

(We will convert time from minutes into seconds.)

Displacement = 3.53*(169*60)

Displacement = 35794.2 m

Now, the displacement in km will be 35.8 km approximately.

Now, let's take that the bike is moving along the positive x-axis. So, it would be written in the following expression:

Displacement = 35.8 a[x] km + 0 a[y] km

Hence, the total displacement in km and vector form in the form of i and j is 35.8 a[x] km + 0 a[y] km.

A car is traveling at a rate of 48miles per hour. What is the car's rate in miles per minute? How many miles will the car travel in 15 minutes?

Answers

Answer:

12 miles in 15 minutes

Step-by-step explanation:

To find the car's rate in miles per minute, we can divide the rate in miles per hour by the number of minutes per hour. There are 60 minutes in an hour, so the car's rate in miles per minute is 48 miles per hour / 60 minutes per hour = 0.8 miles per minute.

To find the number of miles the car will travel in 15 minutes, we can multiply the rate in miles per minute by the number of minutes. The car will travel 0.8 miles per minute * 15 minutes = 12 miles in 15 minutes.

r is 14 and h is 3

=2π(14)(3)

=84π

=263.9

Therefore, 263.9 meters sheet of metal is required.

(ii)To find how much liters of water can tank hold.

Volume of the cylinder =πr²h

=π(14)²(3)

=588π

=1847.25

Therefore, 1847.25 liters of water can this tank hold.

(iii) To find the cost of whitewashing this tank at the rate of rupees 105.5 per 2.

=263.9×105.5

=27841.45

Therefore, Rupees 27841.45 cost of whitewashing this tank at the rate of rupees 105.5 per 2.

A triangle has vertices at (1, 4), (7, 4), and (7,-2). Select all the points which will lie on the median through the point (7,4).

Answers

All the points that will lie on the median through the point (7,4) are given as follows:

(4,1).(5,2).(2,-1).

How to obtain the median of the triangle?

The median that passes through the point (7,4) is a linear function that also passes through the midpoint of the vertices (1,4) and (7,-2).

The midpoint of two points is given by the mean of it's coordinates, hence the midpoint of the vertices (1,4) and (7,-2) is calculated as follows:

x = (1 + 7)/2 = 4.y = (4 - 2)/2 = 1.

Then the two points on the line are given as follows:

(4,1) and (7,4).

Given two points, the slope is calculated as the division of the change in y by the change in x, hence:

m = (4 - 1)/(7 - 4)

m = 1.

Hence:

y = x + b

When x = 4, y = 1, hence the intercept b is obtained as follows:

1 = 4 + b

b = -3.

Then the function is given as follows:

y = x - 3.

And the points that lie on the median are all the points for which the x-coordinate is 3 less than the y-coordinate.

You plant a small tree that begins growing at a constant rate. You measure the tree after 3 weeks and find its height is 33 cm. After 7 weeks, you measure the height of the tree again and it’s height is 38.2cm

a) the constant of variation for this situation

b) how tall is the tree when you planted it (“initial value”)?

c) an equation showing the relationship

d) after how many weeks will the plant be 45 cm tall?

and last question

e) how much time has gone by when the plant is 51.3 cm tall?

Please someone help me with this!!

Answers

a. The constant of variation is 1.3.

b. Initially the tree is  29.1 cm.

c. The equation showing this relationship is y = 1.3x + 29.1.

d. After  12.2 weeks many weeks will the plant be 45 cm tall.

e. 16.85 weeks of time has gone by when the plant is 51.3 cm tall.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at

x = 0.

a. The constant of variation is (y₂ - y₁)/(x₂ - x₁) = (38.2 - 33)/(7 - 3).

= 1.3.

∴ 38.2 = (1.3)7 + b.

38.2 = 9.1 + b.

b = 29.1.

y = mx + 29.1.

b. Now initial constant of variation m = 0.

So, y = 29.1 (cm).

c. The equation showing this relationship is y = 1.3x + 29.1.

d. 45 = 1.3x + 29.1.

1.3x = 15.9.

x = 15.9/1.3.

x = 12.2 weeks.

e. 51 = 1.3x + 29.1.

1.3x = 21.9

x = 16.85 weeks of time have gone.

When you flip a biaed coin the probability of getting a tail i 0. 52. Find the probability of getting a head

Answers

The probability of getting a head given that probability of getting a tail is   0. 52 is  0.48.

Probability of getting at least one head is equal to the probability of all events (100 percent, or 1) less the likelihood of receiving all tails .

Therefore the probability of getting a head is ( 1 - 0.52)

= 0.48

A random event's occurrence is the subject of this area of mathematics. The range of the probability is 0 to 1.

The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.
