A cube has a surface are of 3750 find the length on one side
Agata [3.3K]
A cube has six sides so you divide 3750 by 6 to find the area of a single face. This would be 625. Area is length times width and since it is a cube you know that both are the same. This gives you an answer of 25.

James is at a gift sale where everything costs $4 (tax included).
pantera1 [17]

Answer:

5 gifts

Step-by-step explanation:

Given information:

  • Cost of one gift = $4
  • Total money = $50
  • Money left after purchasing gifts = at least $28

Let x = greatest number of gifts James can buy

Create an inequality with the given information:

⇒ 50 - 4x ≥ 28

<u>Solve the inequality</u>

Add 4x to both sides:

⇒ 50 - 4x + 4x ≥ 28 + 4x

⇒ 50 ≥ 28 + 4x

Subtract 28 from both sides:

⇒ 50 - 28 ≥ 28 + 4x - 28

⇒ 22 ≥ 4x

Divide both sides by 4

⇒ 22 ÷ 4 ≥ 4x ÷ 4

⇒ 5.5 ≥ x

⇒ x ≤ 5.5

We must <u>round down</u> to 5 as if James buys 6 gifts, he will only have $26 remaining.  Therefore, the greatest number of gifts James can buy is <u>5 gifts</u>.
