Step-by-step explanation:
1. use abcos(theta)
a=50

Answer:
4
Step-by-step explanation:
one person is deemed to drive and that person is fixed on the driver's seat no mater which arrangement.
we have now 2 more seats one adjacent to the driver and one rear (two combined).
so the total ways in which all five can be arranged is as follows.
driver, adjacent to him(1) and three back.
driver adjacent to him (different person) and three back.
see the driver is always fixed so we can ignore him.
thus we when driver set fixed , on two remaining seats (adjacent to driver and the back )there can be 4 different combinations.
Answer:
2,143.57
Step-by-step explanation:
The equation for volume of a sphere is 4/3 x pie x r^3. Plug in 8 for r = 512. 512 x 3.14= 1,607.68. 4/3 x 1,607.68 is about 2,143.57
18-2[x+(x-5)]
18-2[2x-5]
18-4x+10
28-4x
-7+x or x-7 <-- Simplified version.
x=7 <-- What x equals.
320/240 = 1.33
1.33 = 133% (move the decimal point over two places to the right)
133% is your answer
hope this helps
