• Packaging of a product can cost a lot of money. Can you design
podryga [215]

The best arrangement can be

  • 3 rows and 4balls each row

So

  • Length of one row=1.8(4)=7.2cm
  • Width=1.8(3)=5.4cm
  • Height=1.8(2)=3.6cm

So

TSA

  • 2(LB+BH+LH)
  • 2(5.4(7.2)+(7.2)(3.6)+3.6(5.4))
  • 2(84.24)
  • 168.48cm²

Total cost

  • 168.48(0.01)
  • 1.685€

Nathan wants to use coordinate geometry to prove that the opposite sides of a rectangle are congruent. He places parallelogram A
Fynjy0 [20]
The formula used to find the length of a line segment is the same formula as the Pythagoras theorem.

We take CD as the hypotenuse of the right-angled triangle and the distance between the x-coordinates and y-coordinates as the length of two short sides.

We can write the formula as
CD = \sqrt{( x_{1}- x_{0})  ^{2}+ ( y_{1}- y_{0})  ^{2}  }
CD = \sqrt{(a-0)^{2}+ (b-b)^{2}  }

Simone has 20 bills. One fifth of the bills are hundreds, 1/4 of them are fifties, 1/10 of them are $20s. The rest of the bills
larisa [96]
If Simone has 20 bills, then:

1/5 of 20 = 4 [hundreds]
1/4 of 20 = 5 [fifites]
1/10 of 20 = 2 [$20s]

4 * 100 + 5 * 50 + 2 * 20 = 400 + 250 + 40 = 690 [out of $780]
4 + 5 + 2 = 11 [out of 20 bills]

So now we can easily find out she had 9 bills of tens - because 20 - 11 = 9 or because (780 - 690) ÷ 10 = 90 ÷ 10 = 9.
