Step-by-step explanation:
An eccentric philanthropist undertakes to give away $100,000. He is eccentric because he insists that each of his gifts be a number of dollars that is a power of two, and he will give no more than one gift of any amount. How does he distribute the money?
To solve this problem, we will simply write 1,00,000 in base 2.
2^17 gives 131072, 2^16 gives 65536.
So, the first gift is 65536, we then need to repeat this process for 34,464 ((100,000-65536 = 34,464), to get all gifts in succession.
6 gifts in all: one each of $32, $128, $512, $1024, $32768, and $65536.
Answer:
(B) 20
Step-by-step explanation:
Let small puppet be represented by-----------------s
Let large puppet be represented by-----------------l
Total number of puppets expression will be: s+l =25---------a
The expression for total costs will be : 1$ s + $2l=$30-------b
Equation a can be written as; s= 25-l ------------c
Use equation c in equation b as
$1( 25-l )+$ 2l = $30
25-l + 2l = 30
25+l =30
l= 30-25 =5
l, large puppets = 5
s, small puppets = 25-5 = 20
Answer choice A is incorrect because 25 is the total number of all puppets
Answer choice C and D are incorrect because the numbers are less that that of small puppets.
Answer: G = 2E + 3
<u>Step-by-step explanation:</u>
Let E represent Elena's age.
Then Gary(G) is two times Elena(E) plus 3 --> G = 2E + 3
