9514 1404 393

Answer:

  • 34.6574 years
  • 34 years, 239.94 days

Step-by-step explanation:

For continuous compounding the "rule of 69" applies. That is the doubling time can be found from ...

  t = 69.3147/r . . . . where r is the interest rate in percent.

Here, r=2, so ...

  t = 69.3147/2 = 34.6574 . . . years

That's 34 years and 240 days.

Use the net below to determine the surface area of the cylinder. (Use 3.14 for Tr.)
baherus [9]

Option D:

Surface area of the cylinder = 753.6 cm²

Solution:

<u>To find the surface area of the cylinder:</u>

Given data:

Radius of the cylinder = 6 cm

Height of the cylinder = 14 cm

The value of π = 3.14

Surface area of the cylinder = 2 \pi r^{2}+2 \pi r h

                                              =2\times 3.14\times6^2+2\times3.14\times 6 \times14

                                              = 226.08 + 527.52

                                              = 753.6 cm²

Surface area of the cylinder = 753.6 cm²                          

Option D is the correct answer.

A baker is putting cupcakes on trays to cool. She put 2 cupcakes on the first tray, 4 cupcakes on the second tray, 8 cupcakes on
elena-14-01-66 [18.8K]

Answer:

64 cupcakes

Step-by-step explanation:

Tray 1 = 2 cupcakes

Tray 2 = 4 cupcakes

Tray 3 = 8 cupcakes

Tray 4 = 16 cupcakes

Tray 5 = 32 cupcakes

Tray 6 = ?

This is a geometric progression

First term, a = 2

Common ratio, r = 4/2

= 2

6th term = ar^n-1

= 2 × 2^6-1

= 2 × 2^5

= 2 × 32

= 64

The 6th tray will have 64 cupcakes
