Answer all 3 as soon as any can

Let's call the two numbers x and y. We know from the problem statement that:

x + y = 1476890

y - x = 1500

To find the greater number, we can use the second equation to solve for one of the variables, and then substitute it into the first equation.

y = x + 1500

Now we can substitute this expression for y into the first equation:

x + (x + 1500) = 1476890

2x + 1500 = 1476890

2x = 1476890 - 1500

2x = 1475390

x = 1475390/2

x = 737695

So the greater number is y = x + 1500 = 737695 + 1500 = 739195

120/20=6 pearl collected 6

Step-by-step explanation:

If Tate collected 20 times as many rare coins as Pearl, we can set up a proportion to find out how many coins Pearl collected. Let x be the number of rare coins Pearl collected. Then we have:

x / 120 = 1 / 20

To solve for x, we can cross-multiply:

20x = 120

Dividing both sides by 20, we get:

x = 6

Therefore, Pearl collected 6 rare coins.

Answer:

Step-by-step explanation:

C = 2[tex]\pi r[/tex]

C = 2(3.14)(36/2)

C = 113.097 units

The solution to the differential equation is given by R = ±1/√(C-a*x), where C is a constant of integration.

To solve this differential equation, we first separate the variables and integrate the equation:

dR/dx = a(R^2+16)

∫ dR/dx  = ∫a(R^2+16)dx

R = ±1/√(C-a*x) + K

where K is an arbitrary constant.

To find the constant of integration, we use the initial condition. We plug in the initial values for x and R to find the constant of integration. For example, if x = 0 and R = 2, then we get

2 = ±1/√(C-0) + K

2 = ±1/√C + K

K = 2±1/√C

Therefore, the solution to the differential equation is given by R = ±1/√(C-a*x) where C is the constant of integration.

Integration is basically used to find the areas of the two-dimensional region and computing volumes of three-dimensional objects.

What is integration?

In mathematics, an integral lends numerical values to functions to represent concepts like volume, area, and displacement that result from combining infinitesimally small amounts of data. Integration is the action of locating integrals.

Differentiation is the opposite of integration.

In other words, reversing the differentiation process merely results in integration. The example below demonstrates it:

dy/dx = 2x since y = x2 Consequently,

(dy/dx) dx = 2x dx = x2.

Together, and dx represent the integration of the function with respect to x.

The anti-differentiation is another name for integration. In this procedure, we are given a function's derivative and asked to determine the function (i.e., primitive). We are aware that cos x is the differentiation of sin x.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

A quadrilateral is a specific type of polygon known as a parallelogram if it contains two parallel opposed sides. A parallelogram has the following qualities:

Answer:

Prabin types 765/9 i.e, 85 words in one minute. Therefore in 30 minutes prabin will type 30 x 85 i.e., 2550 words. Again, he types 1 word in 9/765 minutes. Therefore , he will type 12750 words in 12750 x (9/765) minutes, i.e, 150 minutes.

Prabin would type 2,550 words in half an hour at the same speed. It would take him 150 minutes to type 12,750 words at the same speed.

To find out how many words Prabin would type in half an hour, we need to determine how many minutes are in half an hour. Since there are 60 minutes in an hour, half an hour would be 30 minutes. Now, we can set up a proportion to find the number of words Prabin would type in half an hour:

765 words / 9 minutes = x words / 30 minutes

Cross-multiplying, we get:

9 * x = 765 * 30

Simplifying, we find:

x = (765 * 30) / 9

x = 2,550 words

To find out how long it would take Prabin to type 12,750 words at the same speed, we can set up another proportion using the given information:

765 words / 9 minutes = 12,750 words / t minutes

Cross-multiplying, we get:

9 * (12,750) = 765 * t

Simplifying, we find:

t = (9 * 12,750) / 765

The approximation of the area under the curve f(x) = [tex]2x^2 + 6[/tex] from x = 2 to x = 4 using left rectangles and a step size of Δx = 0.5 is 60.5 square units to one decimal place.

To approximate the area under the curve f(x) = [tex]2x^2 + 6[/tex] between x = 2 and x = 4 using left rectangles and a step size of Δx = 0.5, we have to divide the interval [2, 4] into a number of sub-intervals of width 0.5 and evaluate the function at the left endpoint of each sub-interval.

First find the number of steps: (4-2)/0.5 = 4

The x-coordinates for the left endpoints of each sub-interval are: 2, 2.5, 3, 3.5, 4

We evaluate the function f(x) = [tex]2x^2 + 6[/tex] at each of these left endpoints and multiply the result by the width of the sub-interval (0.5) to find the area of each rectangle.

For [tex]x = 2[/tex], [tex]f(x) = 2(2)^2 + 6 = 14[/tex]

Area = 0.5 * 14 = 7

For [tex]x = 2.5, f(x) = 2(2.5)^2 + 6 = 19.5[/tex]

Area = 0.5 * 19.5 = 9.75

For [tex]x = 3, f(x) = 2(3)^2 + 6 = 24[/tex]

Area = 0.5 * 24 = 12

For [tex]x = 3.5, f(x) = 2(3.5)^2 + 6 = 29.5[/tex]

Area = 0.5 * 29.5 = 14.75

For [tex]x = 4, f(x) = 2(4)^2 + 6 = 34[/tex]

Area = 0.5 * 34 = 17

The sum of the areas of these rectangles is 7 + 9.75 + 12 + 14.75 + 17 = 60.5

Therefore, the approximation of the area under the curve f(x) = [tex]2x^2 + 6[/tex] from x = 2 to x = 4 using left rectangles and a step size of Δx = 0.5 is 60.5 square units to one decimal place.

A stationary point of a function f(x) is a point where the derivative of f(x) is equal to 0. These points are called “stationary” because at these points the function is neither increasing nor decreasing.

Once we have identified the dy dx = 0 solutions, we may utilise the first derivative to ascertain the characteristics of the stationary points. Think about the equation y = x2 + 1.

By differentiating and setting the derivative to zero, we may determine that there is a stationary point at x = 0 since dy dx = 2x = 0. Recall that placing f by x and f by y equal to zero will reveal the location of a function f's stationary point.

In this situation, partial differentiation with regard to x while treating y as a constant results in three x squared plus six x. Any stationary point's nature can be ascertained by introducing its x coordinate into the second derivative of the function, f. (x).

The area of the triangle is 24 square meters.

The area of the triangle can be calculated using the formula A = 1/2bh, where b is the base and h is the height of the triangle. In this case, the base is 8 meters and the height is 6 meters. Therefore, the area of the triangle is A = 1/2bh = 1/2(8)(6) = 24 square meters. Therefore, the answer is D. 24 square meters.

To calculate the area of the triangle, first the base and the height of the triangle must be known. The base is the length of the bottom line of the triangle, and the height is the length of the line from the peak of the triangle to the base. Once the base and height of the triangle are known, the area formula A = 1/2bh can be used.

The formula can be broken down into several steps. First, the base and the height are multiplied together. In this case, it would be 8 x 6. This gives a result of 48. Then, the result is divided by 2, which gives a result of 24. Therefore, the area of the triangle is 24 square meters.

The expected value of the probability can then be calculated by taking the average of this formula over the long run. For example, if the train from Troyes is typically 5 minutes late and the train from Le Havre leaves 10 minutes after it is due to arrive, the expected probability of a delay is (1-5/60)^(10/60) = 0.7355.

We can start by using the concept of percentage concentration, which states that the percentage of alcohol in a solution is equal to the number of milliliters of alcohol in the solution divided by the number of milliliters of the solution, multiplied by 100.

Let's call the number of milliliters of Solution B that Linda uses x.

We know that:

Solution A is 50% alcohol, so it contains 50/100 = 0.5 = 1/2 of alcohol.

Solution B is 10% alcohol, so it contains 10/100 = 0.1 = 1/10 of alcohol.

The resulting mixture is a 20% alcohol solution.

Linda uses 400 milliliters of Solution A.

We can set up an equation using the percentage concentration concept and the information provided:

(400 * 1/2) + (x * 1/10) = (x + 400) * (20/100)

Solving for x:

200 + x/10 = (x + 400) * 0.2

x/10 = (x + 400) * 0.2 - 200

x/10 = x * 0.2 + 80

9x/10 = x * 0.2 + 80

9x = x*2 + 800

x = 800/8 = 100

So, Linda uses 100 milliliters of Solution B to make the resulting mixture a 20% alcohol solution.
