Answer: C

<u>Step-by-step explanation:</u>

∑ 8( $\frac{7}{3}$ )⁽ⁿ⁻¹⁾ from n = 1 to n = 5

n = 1 → 8( $\frac{7}{3}$ )⁽¹⁻¹⁾

= 8 = $\frac{648}{81}$

n = 2 → 8( $\frac{7}{3}$ )⁽²⁻¹⁾

= $\frac{56}{3}$ = $\frac{1512}{81}$

n = 3 → 8( $\frac{7}{3}$ )⁽³⁻¹⁾

= $\frac{392}{9}$ = $\frac{3528}{81}$

n = 4 → 8( $\frac{7}{3}$ )⁽⁴⁻¹⁾

= $\frac{2744}{27}$ = $\frac{8232}{81}$

n = 5 → 8( $\frac{7}{3}$ )⁽⁵⁻¹⁾

= $\frac{19208}{81}$ = $\frac{19208}{81}$

Sum = $\frac{33128}{81}$

= 408.99

An alloy of tin is 15% tin and weighs 20 pounds. A second alloy is 10% tin How many pounds of the second alloy

NemiM [27]

Answer:

30 pounds

Step-by-step explanation:

Amount of tin in first alloy + amount of tin in second alloy = amount of tin in mixture

0.15 (20) + 0.10 x = 0.12 (20 + x)

3 + 0.10 x = 2.4 + 0.12 x

0.6 = 0.02 x

x = 30
