Answer:
each van can transport 15 students
Step-by-step explanation:
186 divied by 2 and you get 93 then you divied that by 6 and you get 15.5 you cant have .5 sutdents on a van so you round down and get 15 students.
One ton = 2000 lbs
Therefore, 1.5 tons = 3000 lbs
3000-300=2700lbs
Joe is 15, 45-15=30 30/2=15
Answer:
-cos^4(x)
Step-by-step explanation:
Step 1: Use the Pythagorean identity : 1=cos^2(x) + sin^2(x)
1-sin^2(x) = cos^2(x)
-1+sin^2(x) = -cos^2(x)
cos^2(x) (-cos^2(x))
Step 2: Factor out common terms cos^2(x)
cos^2(x) (sin^2(x)-1)
Ans: -cos^4(x)
Answer:
solve by substitution method
