Answer:
3^3 in = 27 in
Step-by-step explanation:
The area is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
3^7 in^2 = (3^4 in)×W
(3^7 in^2)/(3^4 in) = W = 3^3 in . . . . . . . divide by the coefficient of W
The width of the tabletop is 3^3 = 27 inches.
___
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
1) a. 15% decrease
2) a. $79.20
3) b. 14.3% increase
4) a. $4.68
#1 explanation:
1435 - 1220 = 215
215/1435 = 0.1498
0.1498 x 100 = 14.98 = 15%
#2 explanation:
220 x 0.6 = 132
220-132=88
88 x 0.1 = 8.8
88-8.8 = 79.2 $
#3 explanation:
32-28=4
4/28=0.1428
0.1428 x 100 = 14.28 = 14.3%
#4 explanation:
275 x 0.15 = 41.25
275-41.25 = 233.75
233.75 x 0.02 = 4.675 = 4.68 $
