Answer:
1,203,650,000 mi³
Step-by-step explanation:
Volume of a sphere is given by V = (4/3)πr³
in this case diameter D, = 1320 mi
radius, r = D/2 = 1320 / 2 = 660 mi
volume V, = (4/3)(3.14) (660)³
= 1,203,649,920 mi³
= 1,203,650,000 mi³ (nearest thousand)
Answer:
480. First one
Step-by-step explanation:
Answer:
<em>4x+7y≤250</em>
Step-by-step explanation:
<u>Inequalities</u>
Let's call:
x = number of small rides
y = number of big rides
Since each small ride costs 4 tickets, x rides cost 4x tickets.
Since each big ride costs 7 tickets, y rides cost 7y tickets.
The total number of tickets is the sum of both:
Total tickets = 4x+7y
The friends have 250 tickets, so the total tickets of the rides cannot be greater than the 250 tickets available, thus:
4x+7y≤250
Your photo is super blurry! I can’t read parts of the problems, so I can’t exactly help you. Sorry! Good luck.
No because the x does not go with the y
