Answer:

d. steam-water equilibrium at 373 K

Step-by-step explanation:

At one atmospheric pressure  , the boiling point of water is 100°C or 273+100 = 373 K in kelvin temperature scale.

so at this temperature vapor pressure of water and steam are in equilibrium .

Find the measure of angle a.
Ostrovityanka [42]

Answer:

a = 127°

Step-by-step explanation:

The 3 angles lie on a straight line and have a sum of 180°, that is

15° + a + 38° = 180°

53° + a = 180° ( subtract 53° from both sides )

a = 127°

What is the slope of the line that passes through (4,26) and (-45,22.)
dusya [7]

It is 1/11 or 4/44.

Explained:

This is because when you subtract 26 and 22 you get 4 and when you subtract 4 and -45. The 45 then becomes a positive since when you get a negative and a negative you get a positive. Then you simplify it by 11.

1400 dollars is placed in an account with an annual interest rate of 5.5%. to the nearest year, how long will it take for the ac
olga_2 [115]

It will take 19 years and 6 months for the account value to reach 2900 dollars

Step-by-step explanation:

Given

Principal amount = 1400 dollars

Rate = 5.5 %

Final value = A = 2900

We have to find t

So,

The formula for simple interest is:

A = P(1+rt)

Putting values

2900 = 1400(1+0.055.t)\\\frac{2900}[1400} = 1+0.055t\\2.071 = 1+0.055t\\2.071-1=0.055t\\1.071 =0.055t

Dividing both sides by 0.055

\frac{0.055t}{0.055} = \frac{1.071}{0.055}\\t = 19.47\ years

Rounding off to nearest tenth

19.5 years

Hence,

It will take 19 years and 6 months for the account value to reach 2900 dollars
