B.) Marua will spend 2 hours to read 100 pages of sociology which means she can only read 60 pages of economics.
Therefore, the opportunity cost of reading 100 pages of sociology is forfeiting 40 pages (2 hours) of economics.

-5 2/7 divided by -2 1/7
sasho [114]
First convert to an improper fraction:
-5 2/7 = -37/7
-2 1/7 = -15/7
So now you have -37/7 / -15/7
When you divide with a fraction, you just flip the numerator and denominator of the divisor and multiply instead, so
-37/7 * -7/15 = 37/15 which would be in "improper" form.
To convert it to mixed number form it would be 2 7/15

Step-by-step explanation:

1. To find the radius divide 7 by 2 which is 3.5

2. Then multiply 3.5 by itself which is 12.25

3. Next multiply 12.25 by 3.14 ( 3.14 = \pi = pi )

4. Lastly your answer will be 38.5

Which statement is correct?
ella [17]

Answer:

The second and third equations are correct.  

Step-by-step explanation:

Note that the equations are all the same, with the exception of the math operation (=,>,<,\leq, etc.).  Let's do one calculation and then decide which of the statements is true.

The components may be simplified by separating the numbers from the exponents and doing the calculations separately:

(2.06x10^-2)(1.88x10^-1)  becomes (2.06*1.88)*(10^-2 * 10^-1)

Left Side:

(2.06*1.88) = 3.91

(10^-2 * 10^-1) = 10^-3  [The exponents add when multiplying]

(2.06x10^-2)(1.88x10^-1) = 3.91x10^-3

Right side:

(7.69/2.3) = 3.343

(10^-2)/(10^-5) = 10^3  [The bottom exponent is subtracted from the top. ( -2 - (-5)) = 3   ]

(7.69x10^-2)/(2.3x10^-5) = 3.343x10^3

For all equations:

LEFT                    RIGHT

3.91x10^-3       3.343x10^3

We can now answer the question.  Is the left side (3.91x10^-3 )      

A.  <

B.  =>

C.  >, or

D.  =

to the right side (3.343x10^3)

We can drop the 10^-3 to make the comparison simpler, since it is the same on both sides.  Think of it as dividing both sides by 10^3.

                                             Correct?

A.    3.91   <   3.34                NO

B.     3.91 =>  3.34                YES  

C.    3.91  >    3.34, or          YES

D.    3.91  =    3.34                NO

5 friends divide 3 bags of apples equally between them. write the division represented in this situation as a fraction.
Kitty [74]
60 hundredths is 60 percent. You can also move the decimal point two places to the right to find the percent equivalent. To write 0.6 as a fraction, you read the decimal, 6 tenths, and write 6 tenths in fraction form. Simplify the fraction by dividing the numerator and denominator by 2, a common factor.
