Answer:320ft^2

Step-by-step explanation:

80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area

a slide on the playground is 12 and 1/2 FEET long..... its 3 feet and 7 inches longer then the small slide.... how long is the s
11111nata11111 [884]
You simply have to add the two numbers together, however, you have to convert everything into inches only. You know that there are 12 inches in one foot. To calculate the length of the longer slide, it is simply doing 12 feet TIMES 12 (since there are 12 inches in one foot). This makes 144 inches. Add 1/2 feet in there, this is adding 1/2 of 12 inches, which is 12/2=6 inches. The long slide is therefore 144+6= 150 inches. Now you want to convert 3 feet and 7 inches into inches only. 3 feet TIMES 12 = 3x12=36 inches. Add 7 inches to this, and you will get 36+7=43 inches. To know how long the small slide is, subtract 43 inches from 150 inches, and this will give you 150-43=107 inches. So, the small slide is 107 inches. :)

lys-0071 [83]

Answer:

  • 2–9  7π/6
  • 3–7  2π/3
  • 4–6  π/3
  • 1–4  π/2
  • 5–10  5π/6

Step-by-step explanation:

The angle between numbers on an analog clock is π/6 radians. So, the angles of interest are ...

  2 to 9 : seven numbers : 7π/6 radians

  3 to 7 : four numbers : 4π/6 = 2π/3 radians

  4 to 6 : two numbers : 2π/6 = π/3 radians

  1 to 4 : three numbers : 3π/6 = π/2 radians

  5 to 10 : five numbers : 5π/6 radians

A thief steals an ATM card and must randomly guess the correct five-digit pin code from an 8 key keypad repetition of digits is
Rus_ich [418]

Answer:

1/32768

Step-by-step explanation:

We have 5 digit pin code plots and 8 choices per slot. Because repetition is allowed (1 digit can have 8 choices) so we multiply out the number of choices per slot . Hence:

8*8*8*8*8 = 8^{5} = 32768

So there are 32768 different combination.

But correct guess on the first try is just only 1 time, so its' probability:

1/32768
