a man deposits 45 into an account the next day he makes 3 deposits of 20 $ each a week later he withdraws 105$
zheka24 [161]

Answer:

The amount available in account at last is $0  

Step-by-step explanation:

Given as :

The withdrawal amount from the account at the end = $105

The first deposit amount = $45

The next three deposit amount = $20 each

I.e The second deposit amount = 3 × $20

Or, The second deposit amount = $60

Let The amount available in account at last = $A

<u>Now, According to question</u>

The amount available in account at last = (first deposit amount  + second deposit amount) - withdrawal amount from the account at the end

i.e A = ($45 + $60) - $105

Or, A = $105 - $105

∴  A = $0

So, The amount available in account at last = A = $0

Hence, The amount available in account at last is $0   . Answer

1001112 = [ ? ]10<br> ?<br> what number belongs where the question mark is
EleoNora [17]

I suppose you're supposed to convert 100111 from base 2 to base 10. We have

100111_2=2^5+2^2+2^1+2^0=32+4+2+1=39_{10}

so the missing number is 39.
