Answer:
8b + 27 ≤ - 29
Step-by-step explanation:
Sum of a number can be written as x or in this case as b because it is an unknown number.
b is multipled by 8 so 8b
"and 27" indicates an addition so therefore, 8b + 27
"at most -29" This is a little bit tricky but ultimately it means 8b + 27 cannot be more than -29. Therefore, it must be lesser than.
However there is a line underneath that lesser than sign meaning lesser than or equal to. I believe that "at most" indicates equal to.
Other than the lesser than or equal to sign I'm unsure about, this inequality should be correct.
Answer:
387
Step-by-step explanation:
Formula: 
Answer:
1) 8.073 (multiply 0.621 by 13km)
2)1,320,000,000(5280ft times 250,000)
3)37.850(10,000 divided by 264.2)
4)4hrs
5)157680000
(60 seconds in one minute and 60 min in one hr so 60 times 60 =3600 in one hr. then multiply 3600 by 24 for the entire day which is 86400sec. Then multiply that day by 365 which is 31536000 times 5 years which gets us our total of 157680000 seconds.
6) 758000 L
1 gal = 3.79 L so we have to multiply 3.79 times 200,000 which gets us 758000
Step-by-step explanation:
1) To get this answer we need to find out how many miles are in one kilometer. 0.621 mile is 1 km so we need to put 13 for km which will get 8.073 miles. SO the answer is 8.073
2) we need to find how many feet are in a mile. 1 mile= 5,280. so 5280 times 250,000 = 1320000000
3) 264.2 gal= 1 cubic meter so 10,000/264.2= 37.850
4) 1 hr= 60 min = 4hrs and 58 minutes roughly
5) 60 sec is 1 minute= so 60 times 60(the minutes in
Answer:
1600
Step-by-step explanation:
P=LxWxH
so P=20x10x8=1600
