Answer:
a = 4.762203156
Step-by-step explanation:
Given:
ab^4 = 12 and a^5b^5 = 7776
Making the equations a subject of a;
a = 12/b^4 and a^5 = 7776/b^5
Finding fifth root on both sides of equation two;
a =
/b
You will get a = 6/b
Equating the two equations;
12/b^4 = 6/b
Multiplying both sides by b^4 gives:
b =
= 1.25992105
We had that a = 12/b^4 so;
a = 12/1.25992105^4 = 12/2.5198421 = 4.762203156
Answer:
3/2
Step-by-step explanation:
5/4 + 4(1/4)^2
5/4 + 4 x 1/16
5/4 + 1/4
3/2
Answer:
D. 20
Step-by-step explanation:
20% of 20 is 4
Answer:
12 machines
Step-by-step explanation:
The production rate per machine is 1240/20 = 62
For 1,984 printers it would take 32 machines (1984/62 = 32)
32 needed minus the 20 they already have means they need 12 more machines.
