The grade received on a certain teacher's 100-point test varies in direct proportion to the amount of time a student spends preparing for the test. If a student receives 72 points on a test for which she spent 3 hours preparing, what score would she receive on the next test if she spent 4 hours preparing?

The teacher woll award the student 96 points for studying for 4 hours

Step-by-step explanation:

The student receives 72 point for preparing a test as long as 3 hours.

If she prepares for another test for 4 hours.

3 hours= 72 points

4 hours=( 72*4)/3

4 hours=72/3 *4

4 hours = 24*4

4 hours= 96 points

The teacher woll award the student 96 points for studying for 4 hours

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
