Answer:
Step-by-step explanation:
Distributive property:
a(b-c) = a*b + a*-c = ab-ac
13.- 11(s+9) = 11*s + 11+9 = 11s+99
14.- -21(x-7) = -21*x -21*-7 = -21x + 147
15.- 13(20-a) = 13*20 + 13*-a = -13a + 260
16.- -8(17+b) = -8*17 -8*b = -8b - 136
17.- (r+1.68)(-0.1) = -0.1(r+1.68) = -0.1*r - 0.1*1.68 = -0.1r - 0.168
18.- 3.25(5.02-t) = 3.25*5.02 + 3.25*-t = -3.25t + 16.315
Answer:
The FIFO method (first-in, first-out) considerate the amount of processing at the beginning and the end of the period. This two moments are converted in equivalent units as it follows:
On June 1, the 30% of 8000 units are completed: 0.30(8000) = 2400 completed units.
During June, 28,000 units are completed.
On June 30, the 80% of 4000 units are completed: 0.80(4000) = 3200 units completed. But these units are remaining from June 1. So, the actual amount of equivalent units from June 1 and June 30 is 3200 - 2400 = 800 units.
Then, we some the total of equivalent units of production 28000 + 800 = 28800.
<em>Therefore, the answer is </em><em>false</em><em>, because is more than 28600.</em>
In order to find out the answer , you just need to count :
Let's say that mary's collection is symbolized by x
2/3 x = 4h
x = 3/2 . 4h
x = 6h
The storybooks they have in total would be : 6h + 4h = 10 h
hope this helps
