Answer:
Step-by-step explanation:
Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2
we have answers as
8. u=16 and v = 
9) y=5 and x=
10) tan 30 =
So y=
x=
11) a=22 and b=11
12) b=1.5 and a=
13) y=
and x=10
No instructions? I'll assume you want the unit rate.
4 miles in 36 minutes = 4/36 miles in 1 minute, or 1/9 mile in 1 minute.
1 3/4 mile in 20 minutes? Multiply both figures by 3:
7 miles in 60 minutes, or 7 miles in 1 hour, or 7 mph.
Answer:
Below.
Step-by-step explanation:
7P4
= 7! / (7-4)!
= 7*6*5*4*3*2*1 / ( 3*2*1)
= 7*6*5*4
= 840.
12C5
= 12! / (12-5)! 5!
= 12*11*10*9*8*7*6*5*4*3*2*1 / ( 7*6*5*4*3*2*1 * 5*4*3*2*1)
= 12*11*10*9*8 / 5*4*3*2*1
= 792.

14/38 simplified would be 7/19
