A student with a mass of 65 kg steps on an improvised raft. He then moves at a speed of 2.0 m/s to cross a flooded street. With what velocity does the raft move assuming it has a mass of 25 kg?
Answers
Answer: 0.2 m/s
Step-by-step explanation:
The student steps on the raft, and then he moves (with the raft) at a speed of 2.0m/s to cross the flooded street.
Then the raft moves with him, at the same speed (notice that the mass of the raft does not matter, suppose that you move at 100km/h in a small car, the speed of the vehicle would be exactly the same as if you where in a truck moving at 100km/h)
Then the speed of the raft is also 2.0 m/s.

The length of a rectangular picture frame is 16 inches, and the width of the picture frame is 12 inches. What is the length of a diagonal of this picture frame in inches?
Answers
Answer:
20 inches
Step-by-step explanation:
A rectangular object can instead be thought about as two right triangles with the hypotenuse being the diagonal we are solving for.
With this in mind the Pythagorean Theorem can be used to solve for c
c^2=a^2+b^2
A=16 inches
B= 12 inches
C= hypotenuse
C^2=16^2+12^2
C^2=256+144
C^2=400
Take the square root of both sides: C = 20 inches

7x-4+8x=6x+8 abcdefghijklmnop
Answers
Answer:
x = 4/3
Step-by-step explanation:
7x − 4 + 8x = 6x + 8
Answer:
x=[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].
