Answer:
the answer is 81.402 in expanded form using the powers of ten = (8 x 10^1) + (1 x 10^0) + (4/10^1) + (0/10^2) + (2/10^3)

Answer:
9,090,900.0099
Step-by-step explanation:
9,090,900.0099
A) 7,2% = 7,2/100 = 0,072
0,072·15L = 1,08L
b) 5,75% = 5,75/100 = 0,0575
0,0575·$17,000 = $977,50
c) 6 1/5% = 6+15/100 = 6+0,15 = 6,15
6,15·$90 = $553,50
d) 2/3% = 2/300
2/300·$200,000 = $1333,4
Answer:
12.) b = (2S/n) - a
13.) x = 1000 - 20y
Step-by-step explanation:
12.) *goal is to isolate b
S = n/2 (a + b)
S(2/n) = a + b
**multiply both sides by 2/n to get rid of n/2
(2S/n) - a= b
***subtract a from both sides to leave b alone on one side
13.) *goal is to isolate x
0.30x + 6y = 300
0.30x = 300 - 6y
** subtract 6y from both sides
x = (300 - 6y)/ 0.30
*** divide 0.30 from both sides to leave x bu itself
x = 1000 - 20y or -20y +1000
****300 ÷ 0.30 = 1000
-6 ÷ 0.30 = -20
Done!
