Here, we can make 2 points
30 feet below the surface of water 10 seconds after he entered the water
100 feet below the surface of water after 40 seconds
So, we have (10,30) and (40,100)
Slope = y2-y1 / x2-x1
So, lets substitute the values of the slope
m = (100-30)/ (40-10)
= 70/30
= 7/3
m = 2 1/3 or 2.33

Question
Find the value of x in each of the following:
Please explain how you got your answer(s), thanks!
Solution 1
The first one: x is 3 because 3 x 3 x 3 is 27
the second one: x is 1/64 because the denominator, 4, to the power of 3 is 64. Anything rad 1 will always be 1, ∛64 is 4.
the third one: x is 1/8 because 8 x 8 x 8 which is the same thing as 8^3 is 512.
∛1/512 (1 divided or multiplied by 1 is always going to be 1)
the fourth one: x is 1331, I know this because I did, 11 x 11 x 11 to get 1331.
Let me know if this doesn't make sense

Question
Write your question here (Keep it simple and clear to get the best answer)the medal zena won for athletics consists of silver and brass in the ratio 3:5.if the medal has a mass of 200g how do i calculate the mass of the silver?
Solution 1
Silver : brass = 3 : 5
Lets take the value as x
Therefore, 3x+5x = 200 ( since the mass of the medal is 200 g )
8x = 200
x = 200/8
= 25
The mass of silver = 3x
= 3*25
= 75 g
Lets take the value as x
Therefore, 3x+5x = 200 ( since the mass of the medal is 200 g )
8x = 200
x = 200/8
= 25
The mass of silver = 3x
= 3*25
= 75 g
Solution 2
Silver : brass = 3 : 5
Lets take the value as x
Therefore, 3x+5x = 200 ( since the mass of the medal is 200 g )
8x = 200
x = 200/8
= 25
The mass of silver = 3x
= 3*25
= 75 g
