1) The initial volume of a balloon is 0.50 L. The initial temperature of the balloon is 150K. The volume in the balloon increase

d to 1.00 L.
What is the final temperature?

Use the below equation. Round to the nearest whole number and do not use units in your final answer.

T2=V2 x T1V1

2) A 2.5L container of an unknown gas has a pressure of 300kPa. The container is squeezed and has a final volume of 2.0L.

What is the final pressure of the container?
Use the below equation. Round to the nearest whole number and do not use units.

P2 =P1V1/V2

3) Charles’ law is
V1T1=V2T2
A closed container has an initial temperature of 300K. The container volume is changed until the final volume is 2L and the final temperature is 425K.

Calculate the initial volume using the equation from Charles' Law.

Use 2 decimal points in your answer and do not use units.

Answer:

The undersigned only for use your own email and delete any and copies and of the itself and to be there is a good time what does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the molecules decreased kinetic energy of the molecules increased chemical energy of the molecules increased kinetic energy of the molecule show does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

Isaac invested $77,000 in an account paying an interest rate of 4.6% compounded continuously. Assuming no deposits or withdrawal
zlopas [31]

Answer:

132,090.30

Step-by-step explanation:

r = R/100

r = 4.6%/100

r = 0.046 per year,

A = P(1 + r/n)nt

A = 77,000.00(1 + 0.046/1)(1)(12)

A = $ 132,090.30

QUESTION 6 OF 17 A Lyft driver has received 160 reviews with an average rating of 4.4 out of 5 stars. If the driver wanted to ra
dexar [7]
He needs 160 5-star reviews in a role. We can write a function to solve this problem. His current total stars is 4.4*160=704. Suppose he needs x more 5-star reviews, then his total stars will be 704+5x. 160+x is the new number of reviews, and the new average will be 4.7, so 4.7*(160+x)=704+5x. The solution is 160. Besides, if you want to get the answer really fast, you can see that 4.7 is right in the middle of 4.4 and 5, so you can immediately guess that the number of new 5-star reviews should be equal to the number of current reviews.

The sum of two numbers is 40 - 13. what are the integers.
Anni [7]
So. let's say the numbers are "a" and "b"

whatever they're, we know a + b = 56

let's say the larger one is "b", so 3 times the smaller is 3*a or 3a
now, 12 less than that, is 3a - 12

and the larger is that, so b = 3a - 12

so   \bf \begin{cases}
a+b=56\\
\boxed{b}=3a-12\\
----------\\
a+\boxed{3a-12}=56
\end{cases}

solve for "a", to see what the smaller one is

what's b? well, b = 56 - a

Jennifer and Chelsea each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same s
zvonat [6]

Answer:

$15.00

Step-by-step explanation:

Suppose 1 rose bush costs r dollars,

Suppose 1 geranium costs g dollars.

Here are 2 equations:

1)6r+14g=146

3r+7g=73

2)r+7g=57

r=57-7g

Put 2) in 1)

3(57-7g)+7g=73

171-21g+7g=73

98=14g

g=7

r=8

7+8=$15.00

Hope I helped!
