Answer:
h = 1.51
Step-by-step explanation:
Divide 243 by 3:
243 / 3 = 81
Subtract the exponents:
8-2 = 6
So you have 81 x 10^6
Now move the decimal point on 81 to have one digit to the left of the decimal point and then add the number of moves to the exponent.
81 becomes 8.1, and you moved the decimal 1 place, so add 1 to the ^6:
Answer is 8.1 x 10^7
Answer:
She bought
22 of the 52 cent stamps and
26 of the 23 cent stamps.
Step-by-step explanation:
Given :
Total stamp increase = 48
Let number of 52 cent stamp = x
Number of 23 cent stamp = 48 - x
The cost equation :
0.52*x + 0.23*(48-x) = 17.42
0.52x + 11.04 - 0.23x = 17.42
0.52x - 0.23x = 17.42 - 11.04
0.29x = 6.38
x = 6.38 / 0.29
x = 22
Hence,
She bought 22 ; 52-cent stamps
And (48 - 22) = 26, 23-cent stamps
