Hope this helped :)
I hope this helps I got it from my math book, Rational numbers are used everyday. Write three instances in which you use each representation of a rational number--fractions, decimals,and percentages-- in your daily activities. Does a certain representation appear to be used most often?
Answer:
7.5
Step-by-step explanation:
So the constant proportionality is easy, it is the depindent veriable (how much it cost) divided by the independent veriable (how much fabric you have).
Put simply you know how much it will cost if you know how many yards you have. so if i have 2 yards i know it cost 15 dolars.
We could make a simple algebraic expretion that describes the proportionality.
C⁒y=7.5
So 7.5 is our constant, so if you know the cost or how many yards we have we always know what the other is.
So if i had 6.7 yards how much would it cost.
It would cost $50.25, what i did was i multiplied 6.7*7.5(our constant) and we got out cost c. Just to dubble check we can plug it in;
50.25⁒6.7 does=7.5 so it works.
From x=a to x=b, with n subintervls, the width between each is (b-a)/n
so from x=3 to x=5 and 4 intervales is (5-3)/4=2/4=1/2
increments of 1/2 each time
we need 4 of them
I see that xi is the right endpoint so I would guess that we take the right <span>Riemann sum
so we start at 3+0.5 or 3.5
so 3.5, 4,4.5,5
C I would say
