P(B) =2X0. 28=0.56
1-0.28-0.56=0.16
P(C)+P(D)=0.16
P(D)=0.16÷2=0.08
-10+4u because you add the 3u and u because they are alike terms then you add together all the other numbers left
Answer:
1, 470
Step-by-step explanation:
4,200 * 0.35 = 1, 470
Let the weight of the full Volume of nails in the box be W.
Let the weight of the box be B.
2/3 W + B = 130 ........i From the first statement.
3/8 W + B = 74 ......ii From the second statement.
Equation (i) Minus (ii)
2/3 W - 3/8 W + B - B = 130 - 74
(16W - 9W) / 24 = 56
7W / 24 = 56.
W = 56 * 24 / 7
W = 192 Pounds.
Substituting V = 64 in equation (i)
2/3 W + B = 130
2/3 * 192 + B = 130
2 * 64 + B = 130
128 + B = 130
B = 130 -128 = 2.
Therefore, weight of box, B = 2 pounds.
