Kisachek [45]
If full then the stadium could have held 60000 people over 3 days.
It really held 17563+18126+16618 over the 3 days = 52307 people. To work out the difference 60000 - 52307 = 7693

The sides of two cubes are in the ratio 2:1. What is the ratio of their volumes ?
olasank [31]

Please mark as brainliest

Answer:

we know that, Volume of cube=a³

Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)

Step-by-step explanation:

ATQ: 2x=a³ and, x=A³

a=³√2x and, A=x

we know that, surface area of cube is 6a²

Thus, surface area of 1st cube = 6(³√2x)²

= 6³√4x²

Surface area of 2nd cube=6(x)²=6x²

Ratio of S.A=(6³√4x²)÷(6x²)

Ratio of S.A=³√4:1

Solve 7(3-x)&lt;5x-15 for x
stepan [7]

7(3 - x) < 5x - 15

  • Distribute 7 inside the parentheses.

21 - 7x < 5x - 15

  • Subtract 21 from both sides.

-7x < 5x - 36

  • Subtract 5x from both sides.

-12x < -36

  • Divide both sides by -12. The equality sign will get flipped because you are dividing by a negative.

x > 3
