A ramp rises 1.5 feet <em>for </em>every 18 feet of horizontal distance. Basically the <em>for</em> is what gives it away. You could also just go with the fact that the x variable normally goes left to right (horizontal) and y goes up and down (Rises and falls) which gives you the same thing. The 1.5 feet is y and 18 feet is x
The answer is -13! Hope this helps!
Let us assume the common ratio = x
Then from the given question we can write
7x + 2x = 450
9x = 450
x = 450/9
= 50
Then the quantity 450 grams can be divided in the ratio of 7 : 2 by = 7x:2x
= (7 * 50) : (2 * 50)
= 350:100
I hope this is the answer you were looking for and the procedure for finding the answer is also absolutely clear to you.
22.8 gms
Step-by-step explanation:
Step 1:
Given,
Mass of the element = 590 gms
Percentage decay per minute = 19.5%
Step 2 :
Fraction of the element remaining at the end of 1 minute = 1 - 0.195 = 0.805
Hence the fraction of element remaining after 15 minutes = 
= 0.03863
So the mass of the element remaining after 15 minutes = 0.03863 * 590 = 22.8 rounded off to the nearest 10th of a gram
mass of the element remaining after 15 minutes = 22.8 gms
