we know that
12,430,000 in expanded form is equal to
12,430,000=1*(10,000,000)+2*(1,000,000)+4*(100,000)+3*(10,000)\\\\ 12,430,000=(10,000,000)+(2,000,000)+(400,000)+(30,000)
therefore
the answer is
(10,000,000)+(2,000,000)+(400,000)+(30,000)
Answer:
Irrational: √2 = 1.4
Step-by-step explanation:
Answer: desktop = $1750, laptop = $1900
<u>Step-by-step explanation:</u>
Let x represent the cost of the desktop
then x + 150 is the cost of the laptop.
.07x + .055(x + 150) = 227
.07x + .055x + 8.25 = 227
.125x = 218.75
x = 1750
desktop (x) = $1750
laptop (x + 150) = $1750 + $150 = $1900

32.5% × ? = 12.48
? =
12.48 ÷ 32.5% =
12.48 ÷ (32.5 ÷ 100) =
(100 × 12.48) ÷ 32.5 =
1,248 ÷ 32.5 =
any rational number can be expressed as a/b, with a and b being integer numbers, and b different to 0.
-7 = -7/1 rational
sqrt(10) irrational (because there is no rational number multiplied by itself that results in 10)
sqrt(16) = sqrt(4×4) = 4 = 4/1 rational
52% = 52/100 rational
1.235 = 1235/1000 rational
