Judah's family wants to ride the bumper boats at a water park. There are 4 children (c) and 2 adults 9 (a) in Judah's family. Th
zhannawk [14.2K]

Answer:

Yes, the boats are safe to ride.

Step-by-step explanation:

40 (4) + 12 (2) ≤ 500

160 + 24 ≤ 500

184  ≤ 500

184 is less than 500.

because I was not sure if you had 9 adults instead of 2, this is the answer:

40 (4) + 12 (9) ≤ 500

160 + 108 ≤ 500

268 ≤ 500

268 is less than 500

What is the solution of sqrt x+2-15=-3
antiseptic1488 [7]

Answer:

Step-by-step explanation:

Without brackets, we are not exactly sure what is under the root sign. There are 3 choices.

sqrt(x) + 2 - 15 = - 3

sqrt(x + 2) - 15 = - 3

sqrt(x + 2 - 15) = - 3

I think the middle one is what you intend. If not leave a note.

sqrt(x + 2) - 15 = - 3                Add 15 to both sides.

sqrt(x + 2) - 15+15 = - 3+15     Combine

sqrt(x + 2) = 12                        Square both sides

x + 2 = 12^2                             Do the right

x + 2 = 144                               Subtract 2 from both sides.

x + 2-2 = 144-2

x = 142

A Unites States naval submarine began at sea level. It submerged 140 ft and then traveled 40 miles. It dove down an additional 1
kodGreya [7K]

Answer: -231 ft

<u>Step-by-step explanation:</u>

The submarine started at sea level = 0

It submerged 140 ft = -140 ft

It traveled 40 miles horizontally so it is still at -140 ft

It dove down an additional 120 ft = -260 ft <em>(-140 + -120)</em>

It traveled 25 miles horizontally so it is still at -260 ft

It rose 29 ft = -231 ft <em>(-260 + 29)</em>

Note: submerged and dove are negative values and rose is positive

0 - 140 - 120 + 29 = -231
