C = 11.6239mm
Circumference Formula is C = 2πr
R = 1/2 D
R = radius
D = diameter
π = 3.14
C = circumference
1/2 3.7 = 1.85
2 x 3.14 x 1.85 = 11.6239
Answer:
78.75
Step-by-step explanation:
450 is increased by 75%
450 + 450*75%
Change to decimal form
450 +450*.75
450+337.5
787.5
Now decrease by 90%
787.5-787.5*90%
Change to decimal form
787.5-787.5*.9
787.5-708.75
78.75
We are given that this is an ideal gas, and that the volume and presumably the number of moles of gas are constant. We can use Gay-Lussac's Law, which describes volume and pressure. We have that pressure is directly proportional to volume. For a change in a gas, we can write the equation as

,
where i denotes initial and f denotes final.
We have that

,

, and

. We need to find

. To do so, let's first rearrange Gay-Lussac's equation to solve for

.

Now, we plug in our values to get

.

.
This seems like a reasonable value, because as temperature goes up, pressure goes up, and an increase in temperature corresponds to an increase in pressure.
Technically, you were given values with only one significant figure, so you can only report the value as

, but this depends on how your instructor usually does these problems!
Answer:
x=3
Step-by-step explanation:
Zeljko's father pays $55 each month.
The cost of the TV bought by Zeljko's father = $660
The payment for the TV is divided monthly for a year.
But one year = 12 months.
Therefore, the amount of money he will pay per month would be the total amount divided by 12, that is,
= 660/12
= $55
Therefore, Zeljko's father pays $55 each month.
