Answer:
It’s 850
Step-by-step explanation:
Divide the figure into 3 shapes, first one being 10ft times 5ft times 5, followed by 20 times 5 times 5 the another with 10 times 5 times 5. I got 850
That's the uniion of sets B and C
that means inclde all the values of both sets (not meaning the ones common to both sets)
so that would include a,b,c,d, 0,a,2,b
a and b repeat so list them only once
that would be {a,b,c,d,0,2}
answer is 4th option
dive the number of miles by the speed
so 450/60 = 7.5 hours
