Answer:
2.93
Step-by-step explanation:
5% in decimal form is 0.05
If 5% is being added, that means that the item will be 105% its original price, which is equal to 1.05
2.79 x 1.05 = 2.93
1-
2.79 ----- 100
x ------------ 5
x= 2.79 * 5/ 100= 0,135
2- 0,135 + 2,79= 2,925
<em>21(a) 8 cm</em>
<em>21(b) 1.6 cm/sec</em>
21(a)
21 cm = 13 cm = 8 cm
21(b)
Increase in depth from 6 sec to 11 sec: 8 cm
Time from 6 sec to 11 sec: 11 sec - 6 sec = 5 sec
Rate = (8 cm)/(5 sec) = 1.6 cm/sec
