In order to calculate your semester grade in this class, each of your two marking period grades account for 40% of your grade, while your final exam is worth the other 20%. Suppose you earned an 87 for the 1st marking period, a 74 for the second marking period, and a 90 on the final exam. What will your semester grade end up at (round to the nearest tenth)?

Step-by-step explanation:

0.12

Step-by-step explanation:

Because 12\%12%12, percent means 121212 per hundred, we can write it in equivalent forms.

\begin{aligned} 12\%&=\dfrac{12}{100} &=\dfrac{3}{25} &=0.12 \end{aligned}  

12% =  100

12 =   25

3 =0.12

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
