Tia measured a greeting card and found that it was 1 decimeter long. How many centimeters are in 1 decimeter?

Advocard [28]

Answer:

10 cm

Step-by-step explanation:

1 decimeter is equal to 10⁻¹ meters.

1 meter is equal to 10² centimeters. We can use a conversion fraction to find the centimeters corresponding to 10⁻¹ meters.

10⁻¹ m × (10²cm/1 m) = 10 cm

1 dm = 10⁻¹ m

10⁻¹ m = 10 cm

Due to the transitive property, 1 decimeter is equal to 10 centimeters.

14(0.89)^x+4.5 =162

lisabon 2012 [21]

$14(0.89)^{x + 4.5} = 162$
$\frac{14(0.89)^{x + 4.5}}{14} = \frac{162}{14}$
$0.89^{x + 4.5} = 11\frac{4}{7}$
$ln(0.89^{x + 4.5}) = ln(11\frac{4}{7})$
$(x + 4.5)ln(0.89) = ln(11\frac{4}{7})$
$\frac{(x + 4.5)ln(0.89)}{ln(0.89)} = \frac{ln(11\frac{4}{7})}{ln(0.89)}$
$x + 4.5 = -2101.14032500$
$x = 2105.64032500$
