Answer:
x=8/7-y/7
Step-by-step explanation:
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.
Mixed number is a natural number plus a proper fraction
a mixed number, is normally more than 1
anyway
percent means parstt out of 100
0.55%=0.55/100=0.055/10=0.0055/1=0.0055
it is 55/10000 as a fraction or 0 and 55/10000 aas a mixed number
decimal it is 0.0055
Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
The height and radius that will give us the smallest amount of paper, should have should have the perfect dimension, in that the diameter should be equal to the height. thus let the diameter be x, the height will be x and the radius will be x/2
thus the volume of the cone will be:
V=1/3πr^2h
=1/3*π*(x/2)^2*x
=0.262x^3
hence the value of x will be:
33=0.262x^3
x^3=125.95
x=(125.95)^(1/3)
x=5.0126=5.01 cm
thus the diameter=height=5.01cm
