A 600 mL flask contains oxygen at 55.0 KPa pressure. A 300 mL flask contains argon at 30 KPa pressure. The two flasks are connected and the gases are allowed to mix and fill the combined volume. What is the total pressure of the resulting mixture?

Hope you could help out! Godspeed!

1) Two tangents to a circle are at right angle with each other. There is a point on the shorter arc of the circle between the two points of tangency that is 4.5 cm away from one tangent, and 4 cm away from the oter. What is the radius of the circle?

Hope you could help! Godspeed!

1) A ball is thrown straight up at a speed of 15.0 m/s, leaving the hand of the thrower 2.00 m above the ground.

a) Compute the ball's speed (on it's way up) when it passes an observer sitting at a window in line with the throw 10.0 m above the point of release.

b) What is the ball's speed on it's way down as it passes the observer?

c) What is the time of travel of the ball on it's way up?

d) What is the time of travel on it's way down?

Hope you could help! Thank you! Godspeed!

1) A yellow messenger robot named Lean Paul is traveling at 1.00 m/s in a straight line along a ramp in a spaceship. If it speeds up to 2.50 m/s in a time of 0.500 s, what is the magnitude of its average acceleration?

2) The fastest animal sprinter is the cheetah, reaching speeds in excess of 113 km/h. These animals have been observed to bind from standing start to 72 km/h in 2.0 s.

a. Compute the magnitude of the cheetah's maximum acceleration, assuming it to be constant and along a straight line.

b. What maximum distance is required for the cheetah to go from rest to 17.9 m/s?

Hope you could help and provide solutions for better understanding, thank you! Godspeed!

1) If the lengths of two sides of an isosceles triangle are 4 cm and 11 cm, find the length of the third side.

2) DJ has two bamboo sticks wit measures 32 cm and 19 cm, if he will make a triangular picture frame, how many possible picture frames can he make, if the third side has integral length?

3) How many different triangles are possible if the measures of the three sides must be selected from the measures 1, 2, 3 and 4?

Please provide solutions for better understanding. Hope you could help me out! Godspeed!

In a convex polygon, exactly five of the interior angles are obtuse. The largest possible number of sides for this polygon is ________.

How do you solve for this? Please state your solution with the equation for me to gain an understanding of the said problem. Thank you! :)

1) A regular hexagon of side 6 has its center at the origin and a diagonal along the x-axis. Find the coordinates of its vertices?

2) What are the lengths of the segments into which the y-axis divides the segment joining (-4, -4) and (5, 8)?

How do you solve these? Hope you can provide solutions so I could get a better understanding of these problems. Thank you, hope you could help me :)

a) Ellaine wants to make a collage using squares. She cuts paper squares in such a way that the ares of each square is 4 times the area of the preceding square. She makes five squares, and the area of the first square is 2 inches^2. What is the total area of the square?

b) How far up and down will a ball travel before stopping if it is dropped from a height of 12 m, and each rebound is 1/3 of the previous distance?

Please help. Thanks. God bless :D

a) There are 800 students in a certain high school in 1982. The trend during the previous years shows a yearly increase of 20% in enrollment. What will the enrollment be in 16 years?

b) A square has a side of length 2 cm. A new square is formed by joining the midpoints of the sides of the first square. If this process is repeated 5 times, what is the area of the sixth square?

Thanks! Godspeed!

Methods or anything? Thanks guys. Please help. God bless :)

Like, improvising without actually buying or spending of money :) Please help! I just wanna give something to a girl made by me from the bottom of my heart :)

Well, the video I've watched so far is in low quality so I can't quite see what was written.

1. 2x(x+3)^-1 - x^2(x+3)^-2

2. u+v / u^-1 + v^-1

3. xy^-2 - yx^-2 / y^-1 - x^-1

4. b^-2 - c^-2 / b^-3 - c^-3

5. 3x^2(x-1)^2 - 2x^3(x-1) / (x-1)^2

6. 4(3x-2)(2x-7)^-1/3 + 8 (2x-7)^2/3

Please help. Kinda confused here :) Godspeed!

Sherwin can paint a car in 3 hours less than his competitor. IF they work together, they can paint the same car in 4 hours. How long does it take Sherwin to paint the car?

I got 9 and 12. But when I added: 4/36+3/36 is not equal to 1/4.

So please help guys. Thanks :D

Use the reciprocal identity:

1. If sin theta = 4/5, find csc theta

Use the ratio identity to find cot theta if

2. sin theta = -5/13 and cos theta = -12/13

Use the equivalent forms of the Pythagorean identity:

3. Find sin theta if cos theta = 3/5 and theta terminates in Q 1

Recall that sin^2theta= (sin theta)^2

4. If tan theta = 2, find tan^3theta

Please help, kinda confused =(

1. Two cars left an intersection at the same time, one heading due north, and the other due west. Sometime later, they were exactly 100 miles apart. The car headed north gone 20 miles farther than the car headed west. How far had each car traveled?
