yes sure, i learned this before so
1. a. make a proportion here, of percentage. 
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again, 
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
Answer:
The nearest whole would be 90
Step-by-step explanation:
If you are rounding a number, 1 -4 makes the number go down, for example 1.4 would round to 1. 5-9 would round up, for example, 1.8 would round to 2
Answer:
||u|| = sqrt((0 + 3)^2 + (4 + 2)^2) = 6.71
||v|| = sqrt((3 + 0)^2 + (3 + 2)^2) = 5.83
slope of u = 4/2 = 2
slope of v = 5/3
=> Option D is correct
Hope this helps!
