Answer:

0.46 kg is your answer

Step-by-step explanation:

We know (by definition) that: 1 g = 0.001 kg.

We can set up a proportion to solve for the number of kilograms.

1 g / 460 g = 0.001 kg / x kg

Now, we cross multiply to solve for our unknown x:

x kg = (460 g / 1 g) * 0.001 kg → x kg = 0.46 kg

Conclusion:

460 g = 0.46 kg

The third term of the sequence is 120. The fifth term is 76.8 The explicit rule for the geometric sequence is an=?(?)n-1

gulaghasi [49]

Answer:

The explicit rule of the geometric sequence

aₙ = 187.5 (0.8)ⁿ⁻¹

Step-by-step explanation:

Step(i):-

Given that the third term of the sequence = 120

tₙ = a rⁿ⁻¹

t₃ = a r³⁻¹ = ar²

120 = ar² ..(i)

Given that the fifth term of the given geometric sequence = 76.8

tₙ = a rⁿ⁻¹

t₅ = a r⁵⁻¹ = a r⁴

76.8 = a r⁴...(ii)

Step(ii):-

Dividing (ii) and (i)

$\frac{ar^{4} }{ar^{2} } = \frac{76.8}{120}$

r² = 0.64

r =√ 0.64 = 0.8

Substitute r= 0.8 in equation (i)

120 = ar²

120 = a(0.8)²

⇒ $a = \frac{120}{0.64} =187.5$

Step(iii):-

The explicit rule of the geometric sequence

aₙ = a rⁿ⁻¹

put a= 187.5 and r = 0.8

aₙ = 187.5 (0.8)ⁿ⁻¹

Please help me with the middle question

Gwar [14]

The angles in a triangle must add up to equal 180. When it gives you angle A and angle B, you add them, then subtract it from 180, which will give you the angle C.

65 + 15 = 80

180 - 80 = 100 = Angle C.

It says to list them from smallest to greatest.

<B = 15, <A = 65, <C = 100

Sonya and her family went to dinner. The cost of the meal was $47.28. They left a 15% tip. What was the total amount sonyas fami

chubhunter [2.5K]

Answer:

$54.37

Step-by-step explanation:

First, need to find 15% of 47.28.

47.28 x .15 = 7.092

Then we add that to the original cost.

47.28+7.092 = 54.372

Round your answer

$54.37

Hope this helped!
