Mathematics

Nataly_w [17]4 years ago
7 0

Answer:

729585

Step-by-step explanation:

1,000,000_{16}-8D6A7B_{16}

Because it's difficult to show long subtraction here, we can instead convert both numbers to base 10 first, subtract regularly, and then convert back.

1,000,000_{16}=1\cdot 16^6=16,777,216_{10} \\\\8D6A7B_{16}=8\cdot 16^5+ 13\cdot 16^4 + 6\cdot 16^3 + 10\cdot 16^2 +7\cdot 16 + 11=

8388608+851968+24576+2560+112+11=9,267,835_{10}

Subtracting one from another, you end up with 7,509,381 in base 10, or 729585 in base 16. Hope this helps!

A worker at a factory earns $12 per hour plus 2.50 for each unit produced that hour. The worker earns a total of $27 in one hour
nevsk [136]

Answer:

The total number of units produced is 6  .

Step-by-step explanation:

Given as :

The earning of worker at the factory = $ 12 per hour + $ 2.50 each unit per hour

The total earning of worker per hour = $ 27

Let The total number of unit produced = x

According to question

The wage worker earn per hour + earning  × per unit produced that hour = Total earning of worker per hour

Or, $ 12 per hour + $ 2.50 each unit per hour × x = $ 27

Or, $ 2.50 each unit per hour × x = $ 27 - $ 12

Or,  $ 2.50 each unit per hour × x = $ 15

∴   x = \frac{15}{2.50}

Or, x = 6

Hence The total number of units produced is 6  .   Answer
