Step-by-step explanation:

92% of (680 kilograms) =

Another statement is, "Volume is directly proportional to the number of moles."

The volume increases as the number of moles increases. It does not depend on the sizes or the masses of the molecules.

V

∝

n

, where

V

is the volume, and

n

is the number of moles.

V

k

is a proportionality constant.

We can rewrite this as

Equal volumes of hydrogen, oxygen, or carbon dioxide contain the same number of molecules.

STP is 0 °C and 1 bar.

One mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L

Example Problem

A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas?

Answer:

The coordinates of the point that divides the line internally in the given ratio is (7,3)

Step-by-step explanation:

To find this coordinates, we use the in renal division formula

we have this as;

(x,y) =( nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

(x1,y1) = (4,-3)

(x2,y2) = (8,5)

(m,n) = (3,1)

So, substituting these values, we have ;

(x,y) = (1(4) + 3)8))/(3 + 1) , (1(-3) + 3)5)/(1 + 3)

(x,y) = (28)/4, (12/4)

(x,y) = (7,3)

Answer:

Answer:

1.5 per hour : 1.2 per hour

Step-by-step explanation:

The computation of the ratio is shown below:

For norma, the one pool would be

= 12  pools ÷ 8 hours

= 1.5 per hour

And for albert, the one pool would be

= 9 pools ÷ 7.5 hours

= 1.2 per hour

So the ratio between them is

1.5 per hour : 1.2 per hour

Answer:

A = 8,820.24 yd²

Step-by-step explanation:

[tex]A = \pi r^{2}[/tex]

r = diameter ÷ 2

r = 106 ÷ 2 = 53

A = (3.14)(53)²

A = (3.14)(2809)

A = 8,820.24 yd²

Answer:

8,820.26 yd²

Step-by-step explanation:

(see attached for reference)

Given:

Diameter, D = 106 yd

π = 3.14

Area of circle

= (1/4) π D²

= (1/4) (3.14) (106)²

= 8,820.26 yd²

Answer:

The answer would be 14in

Step-by-step explanation:

This is the answer because the formula is d=2r

so ur looking for the diameter

plug in the "radius" (7in) in the formula

7 times 2 is 14

14in is ur answer!!!

Answer:

x = 9

Step-by-step explanation:

Distribute

2x+2*5=3x+1

2x+10=3x+1

Subtract 3x from both sides

-x+10=1

Subtract 10 from both sides

-x=-9

Multiply both sides by -1

x=9

Answer: x=9

Step-by-step explanation: 2(x + 5) = 3x + 1

2(x+5)

2x+2(5)

2x+10-10= 3x + 1-10

2x-3x=3x-9-3x

-x/-1=-9/-1

x=9

Answer:

We know that:

For every two flowers that Kayra sells, Mycho sells 5.

Now, in the question we have:

"If Kayra sold 6 newspapers, how many did Mycho sell?"

There is no information about newspapers, so we can't answer anything.

If we had something like:

"If Kayra sold 6 flowers, how many did Mycho sell?"

Well, in this case, we remember that for every 2 flowers that Kayra sells, Mycho sells 5, then the first thing we need to do is count how many groups of 2 flowers we have in 6 flowers, this is:

6/2 = 3 groups.

And for each one of these, Mycho will sell 5 flowers, then the total number of flowers that Mycho sold is:

3*5 = 15 flowers.

Answer:

42,42,96

Step-by-step explanation:

The angles of each plane that must be cut to fit are 42°, 42°, and 96°.

The dimension of each plane is 13.4 ft, 13.5 ft, and 20 ft.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Two angles of the figure are:

96 and 42.

The sum of the angles in a triangle is 180°.

So,

The other angle.

= 180 - (96 + 42)

= 180 - 138

= 42

Now,

The angles of each plane must be cut in 42°, 42°, and 96°.

Now,

The side opposite to the equal angles is equal.

So,

The dimensions of the triangles are 40.5 ft, 40.5 ft, and 60 ft.

The dimensions of each plane.

= 40.5/3,  40.5/3, and 60/3

= 13.4 ft, 13.5 ft, and 20 ft.

Thus,

The angles of each plane are 42°, 42°, and 96°.

The dimension of each plane is 13.4 ft, 13.5 ft, and 20 ft.
