Answer:
after 10 months
Step-by-step explanation:
Let x be the number of months and y be the amount they still owe.
Sin Ian borrows $1000 from his parents, then the y-intercept b= 1000 since he owes $1000 when x = 0. He pays them back $60 each month The slope is then m = -60 . Substituting in b = 1000 and m = -60 into the slope-intercept form of a line then gives y= mx + b=-60x +1000.
Sin Ken borrows $600 from his parents, then the y-intercept b = 600 since he owes $600 When x= 0. He pays them back $20 per month so the amount he owes decreases $20 each month. The slope is then m = -20 . Substituting in
b= 600 and m = -20 into the slope-intercept form then gives y = mx +b = -20x + 600.
They will owe the same amount when they have the same y-coordinate. Therefore -60x+ 1000= y= -20x+600. Solve this equation for x:
-60x+ 1000 = -20x+ 600
1000 = 40x+ 600
400 = 40x
10=x
They will then owe the same amount after 10 months.
Answer:

</h2>
Step-by-step explanation:
To find the value of x we can use either sine or cosine
Using cosine we have

</h3>
From the question
x is the hypotenuse
4 is the adjacent
We have

Hope this helps you
So.. hmm notice the picture below
r = h, due to similar triangles ratio, whatever "h" may be
now, we're given how much water is being poured into the cup per sec
namely dv/dt the volume's rate
so.. hmmm
Since they all begin with 2, you need to look for the biggest number after the decimal point, since it's 4 then 2.4 is the biggest number
just multiply 45 time 31!
