Answer:
Mr Adams worked for 52 hours in four days.
Step-by-step explanation:
To get 52, you divide 78 and 6 and get 13. 13 is how many hours he worked a day. Since we need to find out how many hours he worked for 4 days, we add 13 4 times. If we add, the equation would look like this: 13+13+13+13=52. We can multiply also since it's easier. If we multiply our equation would be 13×4. Therefore, Mr Adams worked 52 hours in four days. Hope this helped
To get the speed of growth of plant we proceed as follows;
rate=(distance)/(time taken)
distance( length) of growth of the plant in 14 days is 3.6 m.
1 day=86400 sec
14 days=86400x14=1,209,600 sec
1 m=1000000 micrometer
3.6 m=3600000 micrometer
thus the rate of growth will be:
3600000/1209600
=2.9762 micrometers per second
7.08 + 2x =15.96
-7.08. -7.08
-------------------------
2x=8.88 divide each by 2
X=4.44
You would plot it in between 4 and 5 but on one of the line marks depending on what there value are
