Anne creates necklaces and rings to sell. It takes her 3 hours to make a necklace and 1 hour to make a ring. If she makes 10 ite
ankoles [38]
Hi! to solve the question, how many necklaces did anne make in 16 hours if she makes 10 items in 2 standard 8-hour work days, we should first check the time she needs to make each item.

3 individual hours to make a necklace, and 1 hour to make a ring. according to the problem, she made 10 items in 16 hours. this problem will most likely be trial and error. let’s try one first guess.

my first guess will be, maybe she will make 6 rings and 4 necklaces. 6 times 1 is 6, which takes 6 hours for the rings. 4 times 3 is equal to 12. 6 + 12 is too high! let’s try again.

what about 6 rings and 2 necklaces? 6 times 1 is 6, so that’s 6 hours. 2 times 3 is 6 hours! 6 plus 6 is 12, which is close, but not quite there!

let’s try 7 rings and 3 necklaces! 7 times 1 is 7 hours. 3 times 3 is equal to 9 hours! total that together, 7 plus 9, is equal to 16 hours spent!

so, the answer would be, “Anne made 7 rings and 3 necklaces within 16 hours.” hope this helped!:)

A sweater that normally costs $32.00 is on sale for $24.00. What is the percent
Vlad1618 [11]

Answer:

25 %

Step-by-step explanation:

Percentage is given by :

\%=\dfrac{\text{original value-new value}}{\text{origial value}}\times 100

Original cost of sweater is $32 and sale cost is $24. So,

\%=\dfrac{32-24}{32}\times 100\\\\=25\%

Hence, 25 % is the markdown on the sweater.

I NEED HELP ASAP <br><br> APEX!!!
igor_vitrenko [27]

The series will be:

4+16+64+.......+2^{50}

Hence, Option A is the right answer

Step-by-step explanation:

The series can be fount out by putting the values of i in the expression written with the summation

The expression is:

2^{2i}

while i = 1 to 25

Putting i = 1

2^{2(1)}\\= 2^2\\= 4

Putting i = 2

2^{2(2)}\\= 2^4\\= 16

Putting i = 3

2^{2(3)}\\= 2^6\\= 64

....

Putting i = 25

2^{2(25)}\\= 2^{50}

The series will be:

4+16+64+.......+2^{50}

Hence, Option A is the right answer
