a=360t
b=280t+(280*.25)
360t=280t+(280*.25)
360t=280t+70
80t=70
t=.875
Answer:
aww you had my question opennnn
Step-by-step explanation:
Well the volume of dirt she needs to remove is equal to length*width*height=6.2*4.9*0.225=6.8355
Now let's find how many bags she needs.
To solve for this, simply divide room in bags from total room.
6.8355/0.87=7.857
Thus Zoe has barely enough, but enough bags.
Answer:
0.430
Step-by-step explanation:
Product has four parts :
For proper functioning, each part must function :
Let the 4 parts be:
A, B, C and D
Proper functioning probability :
A and B = 0.79
C and D = 0.83
For proper functioning :
P(A) * P(B) * P(C) * P(D)
0.79 * 0.79 * 0.83 * 0.83
= 0.42994249
= 0.430
