400lbs/340ft^2
Factor out largest common factor. LCF is the product of shared primes of the numbers prime factorization.
400=2*2*2*2*5*5, 340=2*2*5*17
So the product of the shared primes is 2*2*5=20, so divide the numerator and denominator by 40.
(400/20)lbs/(340/20)ft^2
20lbs/17ft^2 or if you prefer
(20/17)lbs/ft^2
(1 3/17)lbs/ft^2 or approximately
1.18 lbs/ft^2
If they both aren't exchanging the cards and making the fractions from their own picked ones, then Jamie will will have 7/10 and Lauren will have 6/12.
7/10 is a bigger fraction to 6/12
6/12 is 1/2 in simplified form. To check answer- in decimal format, 7/10=0.7 and 1/2 is 0.5. So, we can say for sure that 7/10 is the greatest fraction.
Idk if this wil help but...
Let speed of Matthew be X yards/min Speed of Lowe = 3X yards/min.
Distance covered by Matthew in 30 minutes = 30X
Distance covered by Lowe in 30 minutes = 30(3X)= 90X
90X = 30X + 1200 X = 20 yards/min
Let speed of Matthew be X yards/min Speed of Lowe = 3X yards/min.
Distance covered by Matthew in 30 minutes = 30X
Distance covered by Lowe in 30 minutes = 30(3X)= 90X
90X = 30X + 1200 X = 20 yards/min
For this case, what you should know is that the equations that represent an inverse variation are those that could not form a straight line, for example.
We have then:
Equation 1:
pv = 13
Rewriting:
p = 13 / v
P and v are represent an inverse variation.
Equation 2:
z = (2 / x)
z and x are represent an inverse variation.
Answer:
equations represented inverse variation are:
pv = 13
z = (2 / x)
