Answer:
20 miles
Step-by-step explanation:
Set up a proportion...
0.8 miles is to x miles as 6 mins is to 2.5 hours
*You need to convert 2.5 hours into minutes first, since the first part is in minutes. There are 60 minutes in an hour, so there are 60(2.5) = 150 minutes in 2.5 hours
0.8/x = 6/150
Now solve for x by cross multiplying...
0.8(150) = 6x
120 = 6x
20 = x
She can ride 20 miles in 2.5 hours
Cylinder: 1²(3) = 3
3(9) =27
Prism: 4x3x6 =72
Total: 72+27 = 99in³
Answer:
7. about 41.8 degrees or 0.72972 radians (used
, because the given leg is opposite from the angle)
8. about 50.4 degrees or 0.87946 radians (used
)
9. about 12.8 degrees or 0.224 radians (used
)
10. about 51.3 degrees or 0.8957 radians (used
, given leg is opposite from angle)
Step-by-step explanation:
S.O.H.--C.A.H.--T.O.A
sine = opposite (to angle)/hypotenuse
cosine = adjacent (to angle)/hypotenuse
tangent = opposite (to angle)/adjacent (to angle)
I didn't know if it was degrees or radians, so I did both! I saw you on the film question asking for help, so I just wanted to do so! Have a great day!
