Answer:

4 * 10^9

2.7 * 10^-8

6.776 * 10^7

9.05*10^4

5.409*10^5

9.04 * 10^-3

3.2 * 10^-2

5.12 * 10^8

Explanation:

1. 4,000,000,000

4 * 1,000,000,000 = 4 * (10*10*10*10*10*10*10*10*10) = 4 * 10^9

2. 0.000000027

27 * 10^-9 = 2.7 * 10^-8

0.000000027 = 2.7 * 10^-8

3. 67,760,000 = 6776 * 10000

6776 * 10000 = 6776 * 10^4

6776 * 10^4 = 6.776 * 10^3 * 10^4 = 6.776 * 10^7

4. 90,500

905 * 100 = (9.05 * 100) * 100

(9.05*100) * 100 = 9.05 * 10^2 * 10^2 = 9.05*10^4

5. 540,900

5409 * 100 = (5.409 * 1000) * 100

(5.409*1000)*100 = 5.409*10^3 * 10^2

5.409*10^3 * 10^2 = 5.409*10^5

6.) 0.00904

0.00904 = 904 * 10^-5

904 * 10^-5 = 9.04 * 10^-3

7. 0.032

32 * 10^-3 = 3.2 * 10^-2

8. 512,000,000

512 * 1000000

512 * 10^6 = 5.12 * 10^2 * 10^6 = 5.12 * 10^8

[30 points, will mark Brainliest] Which of the following is the lowest hexadecimal value? Explain why. Options to chose; F2, 81,

larisa86 [58]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

First, we need to convert these hexadecimal numbers into decimal numbers, then we can easily identify which one is the lowest hexadecimal.

The hexadecimal numbers are F2, 81, 3C, and 39.

F2 = (F2)₁₆ = (15 × 16¹) + (2 × 16⁰) = (242)₁₀

81 = (81)₁₆ = (8 × 16¹) + (1 × 16⁰) = (129)₁₀

3C = (3C)₁₆ = (3 × 16¹) + (12 × 16⁰) = (60)₁₀

39 = (39)₁₆ = (3 × 16¹) + (9 × 16⁰) = (57)₁₀

The 39 is the lowest hexadecimal number among the given numbers.

Because 39 hex is equal to 57 decimal.

39 = (39)₁₆ = (3 × 16¹) + (9 × 16⁰) = (57)₁₀

using a timer to generate a random number, develop a program that displays random numbers between 1 and 47 (or whatever) for you

mestny [16]

Answer:

Explanation:

The following code is written in Python. It creates a variable that detects the current time. Then it loops through a range of numbers and chooses the last random number after 2 seconds. Finally, it prints that number to the screen. This function can be called countless times depending on the number of state lottery numbers needed.

import random

import time

start_time = time.time()

while time.time() - start_time < 2:

lottery_number = random.randint(0, 48)

print(lottery_number)
