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 $
Answer:
64 meters^2
Step-by-step explanation:
Break the shape into small parts:
The largest rectangle's area is: 5*11 = 55 meters^2
The smaller rectangle's area: 3*3 = 9 meters^2
55 m^2+9m^2 = 64 meters^2
Answer:
16 x^20
Step-by-step explanation:
Simplify the following:
(2 x^5)^4
Multiply each exponent in 2 x^5 by 4:
2^4 x^(4×5)
4×5 = 20:
2^4 x^20
2^4 = (2^2)^2:
(2^2)^2 x^20
2^2 = 4:
4^2 x^20
4^2 = 16:
Answer: 16 x^20
Answers:
Middle: 1200
Right: 210
Bottom: 240
Bottom Right: 42
Reasoning:
you multiply the numbers that line up with their sides.
so like:
the middle one is 30x40
bottom is 6x40
bottom right is 6x7
right is 30x7
