When the volume of a gas is

changed from mL to 852 mL,

the temperature will change from

315°C to 452°C.

Answers

Answer 1

Answer: The initial volume is 593.76mL

Step-by-step explanation:

As you do not say anithing about the pressure, i guess that the pressure remains constant.

If the gas is an ideal gas, we have:

P*V = n*R*T

where P is pressure, n is number of moles and R is a constant.

Now, initially we have:

P*Vi = n*R*315°C

finally we have:

P*825mL = n*R*452°C

Now we can take the quiotient of those two equations and get:

(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)

Now we have:

Vi/852mL = 315/452

Vi =  (315/452)*852mL = 593.76mL

So when we expand the gas at constant pressure, we increase the temperature.  

Answer 2

Answer:

691 mL

Is she correct?
You must show your working.

Answers

Answer:

Actually, a loaf of bread costs 1.5. Barbara was wrong but only by 10 pence

Step-by-step explanation:

1 box of eggs = 1.2

3 boxes of eggs =3*1.2=3.6

1 jar of mayonnaise =1.8

2 loves of bread=2x

Total price of her purchases =10-1.6=8.4

Setting up the equation:

3.6+1.8+2x=8.4

Solving for x

2x=8.4-3.6-1.8

Line m passes through the points (3, 7) and (6, 12) while line n passes through the points (-5, 1) and (-2, 6). Which statement accurately describes the relationship between the two lines? A. Lines m and n have the same slope so they are parallel. B. Lines m and n have the same slope so they are perpendicular. C. Lines m and n have opposite reciprocal slopes so they are perpendicular. D. Lines m and n have opposite reciprocal slopes so they are parallel.

Answers

Hey there! I'm happy to help!

First, let's find the slope of the two lines. To find the slope, you divide the difference in the y-values by the difference in the x-values.

LINE M

7-12/3-6=-5/-3= 5/3

LINE N

1-6/-5+2=-5/-3=5/3

If lines have the same slopes, they are parallel because they are always moving at the same incline and therefore will never meet. This matches what answer A says.

Therefore, the correct answer is A) Lines m and n have the same slope so they are parallel.

I hope that this helps! Have a wonderful day!

A circle is inscribed with quadrilateral A B C D.
Let the measure of Arc B C D = a°. Because Arc B C D and Arc B A D form a circle, and a circle measures 360°, the measure of Arc B A D is 360 – a°. Because of the ________ theorem, m∠A = StartFraction a Over 2 EndFraction degrees and m∠C = StartFraction 360 minus a Over 2 EndFraction degrees. The sum of the measures of angles A and C is (StartFraction a Over 2 EndFraction) + StartFraction 360 minus a Over 2 EndFraction degrees, which is equal to StartFraction 360 degrees Over 2 EndFraction, or 180°. Therefore, angles A and C are supplementary because their measures add up to 180°. Angles B and D are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠A + m∠C + m∠B + m∠D = 360°, and using substitution, 180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°.

The missing information in the paragraph proof is  inscribed angle theorem that if an angle is inscribed in a circle, the measure of the inscribed angle is half the measure of the intercepted arc.

What is  inscribed angle ?

Inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.

We have,

Quadrilateral [tex]A B C D[/tex] inscribed in Circle.

Measure of Arc [tex]B C D = a^0[/tex].

Arc [tex]B C D[/tex] and Arc [tex]B A D[/tex] form a circle, and a circle measures [tex]360^0[/tex],

Measure of Arc [tex]B A D = 360 - a^0[/tex]

Because of the theorem that if an angle is inscribed in a circle, the measure of the inscribed angle is half the measure of the intercepted arc.

Therefore,

[tex]\angle A = \frac{a}{2}^0[/tex]  and    

[tex]\angle C = (\frac{360-a}{2}) ^0[/tex]

The sum of the measures of angles [tex]A[/tex] and [tex]C[/tex] is,

[tex]\angle A + \angle C = \frac{a}{2}^0 +(\frac{360-a}{2}) ^0=180^0[/tex]

Therefore, angles  [tex]A[/tex] and [tex]C[/tex] are supplementary because their measures add up to [tex]180^0[/tex].

Angles [tex]B[/tex] and [tex]D[/tex] are supplementary because the sum of the measures of the angles in a quadrilateral is[tex]360^0[/tex].

[tex]\angle A + \angle C + \angle B + \angle D = 360^0[/tex]

and using substitution,

[tex]180^0 + \angle B + \angle D = 360^0[/tex]

So,

[tex]\angle B + \angle D = 180^0[/tex]

So, from the above provided proof we can say that the missing information in the proof was inscribed angle theorem.

Hence, we can say that the missing information in the paragraph proof is  inscribed angle theorem that if an angle is inscribed in a circle, the measure of the inscribed angle is half the measure of the intercepted arc.

What is the solution to |10x|greater than -2

Answers

Answer:

The solution is: [tex](-\infty, \infty)[/tex], that is, all real values of x.

Step-by-step explanation:

The modulus of a value x(|x|) is the distance of x to the origin.

A distance is a positive measure, or zero, so |x| is never a negative value.

In this problem:

|10x| > -2

Remembering that the modulus is never negative, which means that for every value of x in the real set, |10x| > -2.

So the solution is: [tex](-\infty, \infty)[/tex], that is, all real values of x.

Estimating π. Using random numbers can accomplish many tasks. For example, it is possible to estimate π using Monte Carlo methods. To get an estimate, you place random points in the square [0, 1] × [0, 1] and estimate π/4 as the ratio of the points that landed inside the unit circle to the total number of points (because the ratio of the area of the circle to the area of the square is π/4). Here is what a few test runs and the corresponding estimates for π might look like with the number of points equal to 100, 1000, and 10,000 respectively?

Answers

Answer:

Estimations of π/4:

100 points: 0.75

1,000 points: 0.768

10,000 points: 0.7819

Step-by-step explanation:

To get an estimate of π/4 you can place random points in the square [0, 1] × [0, 1] and estimate it as the ratio of the points that landed inside the unit circle to the total number of points (because the ratio of the area of the circle to the area of the square is π/4).

We do it for 100 xy points and we get:

Point inside the circle area = 75

Estimation of π/4 = 0.75

[tex]\pi/4\approx=\dfrac{\text{points inside circle area}}{\text{total points}}=\dfrac{75}{100}=0.75[/tex]

We do it for 1,000 xy points and we get:

Point inside the circle area = 768

Estimation of π/4 = 0.768

[tex]\pi/4\approx=\dfrac{\text{points inside circle area}}{\text{total points}}=\dfrac{768}{1000}=0.768[/tex]

If we do it fo 10,000 xy points, we get

Point inside the circle area = 768

Estimation of π/4 = 0.768

[tex]\pi/4\approx=\dfrac{\text{points inside circle area}}{\text{total points}}=\dfrac{7819}{10000}=0.7819[/tex]

The value of π/4 (4 decimals) is 0.7854.

The simulation gets more precise with the increase in the number of points.

V(x) = (f ∙ g)(x)
V(x) = (g + f)(x)
V(x) = (f – g)(x)
V(x) = (g – f)(x)

Answers

Answer:

V(x) = (f ∙ g)(x)

Step-by-step explanation:

Note. There is no table attached.

However it can solved with remaining information given.

The volume of a prism is

V = bh, where b is the area of the base, and h is the height

If we have a function for the volume V(x) it has to be equal to a product of functions for the area and the height

Therefore the function will be similar to:

V(x) = (f*g)(x) which is effectively V(x) = f(x)*g(x), where functions f and g represent the area and height

So the correct option is the first one

To find the probability of a customer preferring beef tips over the other menu items, divide the quantity of customers that preferred beef tips over the total number of customers that participated in the survey:

28 / (42 + 28 + 30) = 28/100 = 28%

There is a 28% chance that beef tips is the new preferred menu item.

11: Out of a similar group of 375 customers, predict how many more customers will prefer chicken carbonara to shrimp scampi.

There are 100 customers that participated in the pre-existing survey. A grand total of 375 participants in a similar survey would mean that each food's preference would grow in a similar fashion.

100 * 3.75 = 375

You can then multiply each response group by 3.75 to find how many people prefer chicken carbonara and shrimp scampi.

42 * 3.75 = 157.5

30 * 3.75 = 112.5

Then, subtract the quantities to find out how many more people prefer chicken to shrimp.

Answer:

The smallest angle of the triangle is 33.030°.

Step-by-step explanation:

The angles of triangle can be determined with the help of the Law of Cosine and the fact that sum of all angles equals to 180°:

[tex]\cos A = -\frac{6^{2}-9^{2}-11^{2}}{2\cdot (9)\cdot (11)}[/tex]

[tex]\cos A = 0.838[/tex]

[tex]A \approx 33.030^{\circ}[/tex]

[tex]\cos B = -\frac{9^{2}-6^{2}-11^{2}}{2\cdot (6)\cdot (11)}[/tex]

[tex]\cos B = 0.575[/tex]

[tex]B \approx 54.847^{\circ}[/tex]

[tex]C = 180^{\circ} - A - B[/tex]

[tex]C = 180^{\circ} - 33.030^{\circ} - 54.847^{\circ}[/tex]

[tex]C = 92.123^{\circ}[/tex]

The smallest angle of the triangle is 33.030°.
