Answer:
no
Step-by-step explanation:
Volumes are in ratio 27 : 1331
so ratio od individual lengths = cube roots = 3 : 11
and surface areas will be in the ratio 3^2 : 11^2 = 9:121
so surface area of the larger figure is 121 * 18 / 9 = 242 mm^2
Answer: x = {-4, 5}
<u>Step-by-step explanation:</u>
log (10x + 200) = log (x²) + log (10)
log (10x + 200) = log (10x²)
10x + 200 = 10x²
0 = 10x² - 10x - 200
0 = x² - x - 20
0 = (x - 5)(x + 4)
0 = x - 5 0 = x + 4
x = 5 x = -4
Check for extraneous solutions:
10x + 200 > 0 x² > 0
x = 5 10(5) + 200 > 0 (5)² > 0 both are satisfied
x = -4 10(-4) + 200 > 0 (-4)² > 0 both are satisfied
Both solutions are valid!

Answer:
<u>The correct answer is 61,650 Yens</u>
Step-by-step explanation:
US$ in cash that Ben has = 500
Exchange rate (US$/Yen) = 1 : 123.3
For calculating the total amount in Yens that Ben has, we use this formula:
Yens in Cash = US$ in Cash * Exchange rate given
Yens in Cash = 500 * 123.3
Yens in Cash = 61,650
<u>After converting the US$ 500 Ben has, he will receive Yens 61,650</u>
