Answer:
(a) 1.2b
(b) 1.4h
(c) A = 1.68bh
(d) 68%
Step-by-step explanation:
(a) If 20% of b is added to b, you have ...
b + 0.20b = 1.2b
__
(b) Similarly, if 40% of h is added to h, you have ...
1.4h
__
(c) The area of the new rectangle is the product of the new dimensions:
A = (1.2b)(1.4h)
A = 1.68bh
__
(d) The original rectangle area is A = bh, so the percentage change can be computed as ...
(A'/A -1)×100% = ((1.68bh)/(bh) -1)×100% = (1.68 -1)×100% = 68%
The given increases in base and height increase the area by 68%.
Answer:
$ 12.6 / h
Step-by-step explanation:
5% of 12 = 0.05 * 12 = 0.6
Now adding it to the amount he makes, since it is a raise:
0.6 + 12 = 12.6 $ / h
Another (and faster) way to calculate it:
1.05 * 12 = 12.6
Answer:
its 18
Step-by-step explanation:
Yes, they are independent because P(A) ⋅ P(B) = P(A ∩ B)
