What is the pressure exerted by 100 N force on a circular surface of radius 10 m ? ( Area of circle should be used ) ANSWER FAST

Tcecarenko [31]

Answer:

0.318 Pa

Step-by-step explanation:

Area of a circle= πr²

Area= π x 10²

Area= 314 m²

Pressure = force/area

Pressure = 100/314

Pressure = 0.318 Pa

P.S. You can substitute Pascals for N/m²

Hope this helps!

Find HCF of Question number 23

trapecia [35]

Answer: x - 2

Step-by-step explanation:

HCF is more commonly referred to as GCF (greatest common factor)

Factor each expression to see which factor(s) they have in common.

$x^4 - 8x\implies x(x^3-8)\\= x\boxed{(x-2)}(x^2+4x+4)\\\\\\3x^2-8x+4\implies 3x^2-6x-2x+4\implies3x(x-2)-2(x-2)\\=(3x-2)\boxed{(x-2)}\\\\\\2x^2-5x+2\implies 2x^2-4x-x+2\implies 2x(x-2)-1(x-2)\\=(2x-1)\boxed{(x-2)}$

The only factor that all three expressions have in common is: x - 2

Sin 0 = 0.731353701, 0º PLEASE HELP!!

Snezhnost [94]

Answer:

The two solutions for $\sin \theta = 0.731353701$ are $\theta_{1} \approx 47^{\circ}$ and $\theta_{2}\approx 133^{\circ}$ , respectively.

Step-by-step explanation:

The sine function is positive in the first and second quadrants, that is, $0^{\circ}< \theta < 180^{\circ}$ . Then, there are two solutions for the given value by means of the following inverse trigonometrical function:

$\theta = \sin^{-1} 0.731353701$

$\theta_{1} \approx 47^{\circ}$ and $\theta_{2}\approx 133^{\circ}$

The two solutions for $\sin \theta = 0.731353701$ are $\theta_{1} \approx 47^{\circ}$ and $\theta_{2}\approx 133^{\circ}$ , respectively.

Simone has 5 in her flower shop.Each employee works 6 4/15 hours a day how many hours in total do the 5 empoyees work per day?

kodGreya [7K]

To figure out the total amount of hours an employee works, we have to multiply the total amount of employees by the amount of hours each employee would work.

To simplify the mixed fraction of hours they work, convert the mixed fraction into an improper fraction:

$6 \frac{4}{15}$

Multiply the whole number by the denominator:

$6 \times 15 = 90$

Add this number to the numerator to convert the mixed fraction into an improper fraction:

$90 + 4 = 94$

$6 \frac{4}{15} = \frac{94}{15}$

Now we can multiply the two numbers together (note that a whole number can be treated as the number above the denominator 1):

5 employees working 94/15 hours a day:

$\frac{5}{1} \times \frac{94}{15} = \frac{470}{15}$

To simplify this fraction, divide the numerator by the denominator:

$470 \div 15 = 31 R 5$

The whole number stays as a number, and the remainder is the new numerator:

$31 \frac{5}{15}$

The fraction can be further simplified by dividing both the numerator and denominator by the greatest common factor:

Factors of 5: {1,5}
Factors of 15: {1,3,5,15}

$\frac{5}{15} \div \frac{5}{5} = \frac{1}{3}$

$31 \frac{5}{15} = 31 \frac{1}{3}$

The 5 employees will work a total of 31 and 1/3 hours a day.
