how to convert torr to mmhg

Answers

Torr and mmHg are two units of pressure that are often used interchangeably. In fact, 1 mmHg is equal to 1 torr, which means that they are equivalent units of measurement.

To convert torr to mmHg, you can simply multiply the pressure value in torr by 1, since 1 torr is equivalent to 1 mmHg. For example, if you have a pressure of 760 torr, you can convert it to mmHg as follows:

760 torr x 1 mmHg/torr = 760 mmHg

Therefore, 760 torr is equivalent to 760 mmHg. Alternatively, you can also convert mmHg to torr by dividing the pressure value in mmHg by 1. For example, if you have a pressure of 760 mmHg, you can convert it to torr as follows:

760 mmHg ÷ 1 mmHg/torr = 760 torr

Therefore, 760 mmHg is equivalent to 760 torr.

What is Simpson's 1 3rd rule?

Answers

Simpson's 1/3rd rule is a method of numerical integration that is used to approximate the value of a definite integral.

It is based on the idea of approximating the area under a curve by dividing it into a series of trapezoids and calculating the area of each trapezoid. The formula for Simpson's 1/3rd rule is:

∫abf(x)dx ≈ (b-a)/6 [f(a) + 4f((a+b)/2) + f(b)]

In this formula, a and b are the limits of integration, and f(x) is the function being integrated. The rule is called the "1/3rd rule" because the coefficient of the middle term is 4/3, which is equal to 1/3 when multiplied by the 3 in the denominator.

To use Simpson's 1/3rd rule, you first need to divide the interval [a,b] into an even number of subintervals. Then, you can apply the formula to each subinterval to get an approximation of the integral over that subinterval. Finally, you can add up the approximations for each subinterval to get an approximation of the integral over the entire interval.

Simpson's 1/3rd rule is a more accurate method of numerical integration than the trapezoidal rule, but it is still an approximation. The accuracy of the approximation depends on the number of subintervals used and the smoothness of the function being integrated.

Jim rented a truck for one day. There was a base fee of 15.99 and there was an additional charge of 86 cents for each mile driven. Jim had to pay 206.91 when he returned the truck. For how many miles did he drive the truck?

Answers

The required, Jim can drive the truck for approximately 221.51 miles.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

We can use algebra to solve this problem. Let x be the number of miles Jim drove the truck. Then the total cost can be represented as:

15.99 + 0.86x = 206.91

To find the number of miles driven, we can subtract the base fee from both sides of the equation:

15.99 + 0.86x - 15.99 = 206.91 - 15.99

0.86x = 190.92

Finally, we can divide both sides of the equation by 0.86 to find x:

x = 221.51 miles

So, Jim drove the truck for approximately 221.51 miles.

Answers

Answer:

5 weeks

Step-by-step explanation:

Let factory B produce the same amount of shoes as factory A in w weeks.

then,

70+50w = 120+40w

50w - 40w = 120 - 70

10w = 50

PLEASE HELP I REALLY NEED IT! Write an equation for the nth term of the geometric sequence 5,15,45,135,405,…
Then find a8

Answers

Answer:

              An equation to represent the given geometric sequence would be [tex]a(x)=5*3^{x-1}[/tex], and a(8) of the geometric sequence will be 10,935.

Step-by-step explanation:

              In order to write an equation for a geometric sequence, first we must analyze the sequence to find its starting value and its constant ratio. The starting value is simply the first term in the sequence, which is 5. As for the constant ratio, it is the rate of change that the equation uses. In this sequence, the constant ratio is 3. Now, we can write out an equation for this geometric sequence.

              We know the first term of the sequence is 5, and the common ratio is 3, so we can write out a function for the geometric sequence, which will be [tex]a(n)=5*3^{n-1}[/tex]. NOTE that the exponential power is n - 1, and not n. This is because the first term of the sequence is 5, and not the "0th" term, therefore we must subtract 1 from n (the term number) to have the right sequence.

              Lastly, we can use the equation [tex]a(n)=5*3^{n-1}[/tex] to find the 8th term of the sequence by replacing n with 8. So [tex]a(x)=5*3^{n-1}[/tex] would become [tex]a(8)=5*3^{8-1}[/tex], and you will get [tex]a(8)=5*3^{8-1}[/tex] ⇒ [tex]a(8)=5*3^{7}[/tex] ⇒ [tex]a(8)=5*2187[/tex] ⇒ [tex]a(8)=10,935[/tex]. Therefore, the equation for the nth term of the geometric sequence would be [tex]a(n)=5*3^{n-1}[/tex], and the 8th term of the sequence is 10,935.

Answers

All 4 helpers will be at the clinic on the same day 7 times in 12 weeks.

What is Prime Factorization?

"Prime Factorization" is the process of determining which prime numbers multiply together to get the original number.

To find the number of times in 12 weeks that all 4 helpers will be at the clinic on the same day, we need to find the least common multiple (LCM) of the numbers 4, 6, 2, and 3.

First, we can find the prime factorization of each number:

4 = 2 x 2

6 = 2 x 3

2 = 2

3 = 3

Next, we can find the LCM by taking the highest power of each prime factor that appears in the factorizations:

LCM = 2 x 2 x 3 = 12

Therefore, all 4 helpers will be at the clinic on the same day every 12 days. Since 12 weeks is equivalent to 84 days, we can divide 84 by 12 to get the number of times:

84 ÷ 12 = 7

So, all 4 helpers will be at the clinic on the same day 7 times in 12 weeks.

A complex number is one that has the formula a + bi, where I is the imaginary unit and a and b are real numbers. A and b are the real and imaginary halves of a complex number, respectively.

In order to expand the real number system to include answers to polynomial equations that couldn't be solved with just real numbers, complex numbers were first introduced. Many branches of mathematics and science, such as computer science, physics, and engineering, are based on the idea of a complex number.

The absolute value of a complex number "a + bi" can be calculated as the square root of the sum of the squares of its real and imaginary parts:

|a + bi| = √(a² + b²)

In this case, a = 2 and b = -3, so:

|2 - 3i| = √(2 + (-3)²)

          = √(4 + 9)
