valentina_108 [34]

Answer: $2^{n} -1$

Justification:

As told in the statement, n stands for the number of bits, and $2^{n}$ is the highest number of ways n bits can be arranged in the system.

Now, Antonio wants to show that the character can collect one less key than that. So, that number is $2^{n}$ less 1, which is what the formula $2^{n}$ - 1 states.

What is the perimeter of the fifth square in this pattern?

torisob [31]

The first square has side lengths of 4 units(because the square root of 16 is 4). The second square has side lengths of 8 units. The third square has side lengths of 12 units. As you can tell, the side lengths increase by 4. So the fourth square will have side lengths of 16 units, and the fifth square will have side lengths of 20 units. The question wants the perimeter, so the answer is 20*4(sum of 4 sides of equal lengths) which is 80 units.

EXPLANATION .:

_____(7)______________

Stacy's earning per hour babysitting

= 12$

Thus on Friday to earn 36$,

she would have worked 36/12 = 3 hours

On Saturday she earned 60$,

thus the time she worked = 60/12 = 5 hours

So the total time Stacy babysited on both days = 3+5 = 8hours

_______(8)__________________

Total ounces with Marco = 147

Ounces required for 1 pizza = 13

Ounced required for 1 breadstick = 2

Now when he has already made 3 breadsticks thus he would have used 3×2 = 6 ounces

So the remaining ounces = 147-6 = 141

Hence he can make 141/13 = 10.8 or 10 pizzas.

___________(10)_____________

Mr.Dundford gives 6 pencils to each student => for 30 students the pencils required would be 30×6 = 180

Now when he had already 24 pencils Thus the remaining = 180-24 = 156

Also there are 12 pencils in a packet

=> packets required = 156/12 = 13
