Answer:

the 10th term in the pattern is 92.

Step-by-step explanation:

We have to find the 10th term in the pattern with the formula 10n - 8.

We have:

aₙ = 10n - 8

Here, n is the position of terms.

Putting n = 10 in the given formula , we get,

aₙ = 10n - 8

a₁₀ = 10(10) -8

a₁₀ = 100 - 8

a₁₀ = 92 is the 10th term in the pattern with the formula 10n - 8.

Answer:

is = 92

Step-by-step explanation:

To answer this question substitute n = 10 in the formula of the given equation.

So, we have

$a_n = 10n - 8\\a_{10} = 10*(10) - 8\\a_{10} = 100 - 8\\a_{10} = 92$

The volumes of two cubes are 32ft^3 and 1372ft^3

ser-zykov [4K]

Answer:

1) 8 : 343

2) 42.875 or 42 ⅞

3) 4 : 49

4) 16ft²

Step-by-step explanation:

Volume of cube: s³

Surface area of cube: 6s²

_____________________

32ft^3 and 1372ft^3 →

32 : 1372 = 8 : 343

343 / 8 = 42 ⅞ = 42.875

s³ → 6s²

s³ = 8, s = 2, s² = 4.

s³ = 343, s = 7, s² = 49.

These are proportional so it is already in the simplest ratio so it is not necessary to multiply by 6.

s³ → 8 : 343

6s² → 4 : 49

(4 / 49) × 196ft² = 16ft²
