(x,y)
domain is inputs (normally x or first number)
range is outputs from the given domain (normally y or second number)
domain is just all the first numbers
range is all the second numbers
ignore repeats
domain: {0,4,5}
range: {2,3,5,7}
100+2 or 50+52 these would both work
Every 3rd number is even with 2 odd numbers in between successive even numbers.
999/3 = 333 x 2 = 666.
Answer:
11200 for 7 engines for a total of 80 hours
Step-by-step explanation:
You have 8 engines burning 12000 .for 10 hours.
Divide 10 hours into 12000=1200 PER hour.
1200 ÷8 engines = 140 per hour per engine.
140 × # of hours (12)=1680 for 12 hours per engine.
# of engines × 1680 for 12 hour/per engine
5×1680 = 8400 of fuel for 12 hours/5 engine
Then you have 2 that runs 10 hours
2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours
8400. + 2800= 11200 of fuel for 6 engines
