Answer:
The diameter of the specimen in centimeters is 103 cm.
Step-by-step explanation:
In order to determine the diameter in centimeters of the largest specimen of jellyfish, knowing that said diameter is 1.03 meters, and that 1 meter is equal to 100 centimeters, the following calculation must be performed:
1.03 x 100 = X
103 = X
Therefore, the diameter of the specimen in centimeters is 103 cm.
Let she work for x hours as carpenter !
so earned money = 20x
and for blacksmith she must work for 30-x hours
so earned money = (30-x) ×25
so putting in eqn;
20x+25(30-x) = 690
so, x= 60/5 = 12
so she works for carpenter for 12 hrs and 30-12= 18 hrs for blacksmith !!.....answer !!
