You practice your basketball shots every day. On Friday you made 20 shots. On Saturday you made 16 shots. What is the percent de

STatiana [176]

So,

All you have to do to find the percent decrease is to subtract your score on Saturday from your score on Friday and divide the result by your score on Friday. If you let "f" represent your score on Friday and let "s" represent your score on Saturday, you can re-write this mathematically:

$\frac{f - s}{f} = percent\ decrease$

Substitute.
$\frac{20 - 16}{20} = percent\ decrease$
$\frac{4}{20} \ or\ \frac{1}{5}\ or\ twenty\ percent = percent\ decrease$

The percent decrease in shots you made was 20%. That would be option C.

An angle measures 64.8° less than the measure of its complementary angle. What is the measure of each angle?

kirill115 [55]

Answer:

77.4 degrees and 12.6 degrees

Step-by-step explanation:

Let the angles be x and x - 64.8.

Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :

x + x - 64.8 = 90

2x = 154.8

x = 77.4 degrees

x - 64.8 = 77.4 - 64.8 = 12.6 degrees
