Find the unit rate for each Olivia and Ryan:
2 2/5 km 15 36 km
------------ * ------- = ------------ = 3.6 km/hr (Olivia)
2/3 hr 15 10 hr
4 1/2 km 2 9 km
------------- * --------- = --------- = 3 km/hr (Ryan)
1 1/2 hr 2 3 hr
Olivia walked 0.6 km/hr faster than did Ryan.
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
Cos 70 = horizontal distance /
100 horizontal distance = 100 cos 70 = 32.2feet
3/8x - 1/2x = 3
3/8x - 4/8x = 3
-1/8x = 3
-x = 24
x= -24
Step-by-step explanation:
=> x + 80 + 20 = 180
=> x + 100 = 180
=> x = 180 - 100
=> x = 80°
