Answer:

3.2 or 3 1/5

Step-by-step explanation:

If you are dividing by a half then you can just think of, in your case, 8 divided by 2 minus 1/2 which would get you to 3.5, or 3 and 1/2, then you just make 1/5 into a decimal and that is your new second digit.

What is equivalent to 3 to the negative 2nd power
VladimirAG [237]
3 to the negative second power is written like this: 3^{-2}. 

When simplifying an expression with a negative exponent, you take a positive version of the exponent, in this case that would be 2, and apply that to the base. 
After doing that, we have 9. 
The next step is to put one over that number.
In this case, now after doing that the answer is \frac{1}{9}. 

Hope this helps!

Which is the quotient if 3/5 and 1/10?
AlladinOne [14]

Answer:

6

Step-by-step explanation:

We have two fractions and are asked to find the answer if they both are divided.

3/5 and 1/10.

When we divide fractions, we need to follow KCF

KEEP - Keep the fractions

CHANGE - Change the division sign to a multiplication sign

FLIP - Flip the second fraction

Follow :

KEEP :

3/5 / 1/10

CHANGE :

3/5 * 1/10

FLIP :

3/5 * 10/1

Now we need to multiply, which is simple because it's multiplying across :

\frac{3*10}{5*1}

30/5

Simplify by dividing the numerator and denominator by 5 :

\frac{30/5}{5/5} = \frac{6}{1}

Divide the numerator by denominator :

\frac{6}{1} = 6

20.5 ft = 10.25 in
25 ft = 17.5 in

8.5 in and 11 in. no, the drawing will not fit, because the proportions is larger than 8.5 in and 11 in.
