To convert minutes in hours, you have to divide by 60.

We can distribute this division in a smart way: since $60=6\times 10$ , we have

$\dfrac{19.2\times 10^8}{6\times 10} = \dfrac{19.2}{6} \cdot \dfrac{10^8}{10} = 3.2 \cdot 10^7$

If a boat goes down stream 72 milesind upstream 60 miles in 6 hours, the rate of the river and the rate of the boat in still wat

andre [41]

Answer:

Speed of boat in still water = 11 miles per hour.

Step-by-step explanation:

Speed = distance / time

or

Distance= Speed * time

Let s be speed of the boat upstream and r be the speed of the river.

Then

Upstream speed= s- r = 60/6= 10 miles per hour

Downstream speed= s+r= 72/6= 12 miles per hour

Therefore

s-r= 10--------- equation A

s+r= 12--------- equation B

Adding equation A and Eq. b

s-r= 10--------- equation A

<u>s+r= 12--------- equation B </u>

<u>2s = 22 </u>

<u />

or

s= 22/2= 11 miles per hour.

Speed of boat in still water = 11 miles per hour.

point) Covert the following integers from decimal notation to binary notation. (Do not put extra zeros in front of your binary n

Paha777 [63]

Answer:

The binary notation of the integer 234 is 11101010.

Step-by-step explanation:

To convert decimal to binary you must:

Divide the number by 2.
Get the integer quotient for the next iteration.
Get the remainder for the binary digit.
Repeat the steps until the quotient is equal to 0.
Write the remainders from bottom to top.

So, to convert the decimal number 234 to binary

$\left\begin{array}{ccc}\mathrm{Division\:by \:2}&\mathrm{Quotient}&\mathrm{Remainder}\\234/2&117&0\\117/2&58&1\\58/2&29&0\\29/2&14&1\\14/2&7&0\\7/2&3&1\\3/2&1&1\\1/2&0&1\end{array}\right$

The binary notation of the integer 234 is 11101010.
