Answer:

see explanation

Step-by-step explanation:

Note the common difference d between consecutive terms of the sequence

8 - 6 = 10 - 8 = 2

This indicates that the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 6 and d = 2, thus

a_{n} = 6 + 2(n - 1) = 6 + 2n - 2 = 2n + 4 ← explicit formula

Hence

a_{130} = (2 × 130) + 4 = 260 + 4 = 264

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20in
Rom4ik [11]

Answer:

100 inches

Step-by-step explanation:

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.

This is calculated using proportion

Side length/Perimeter

Hence:

Side length of smaller triangle = 19 inches

Perimeter of smaller triangle = 95 inchee

Side length of larger triangle = 20 inches

Perimeter of larger triangle = x

19/95 = 20/x

Cross Multiply

19x = 95 × 20

x = 95 × 20/19

x = 100 inches

The perimeter of the larger triangle = 100 inches

50 point if u due right plzzz
Tresset [83]

The diagonals of a square bisect one another and are perpendicular.

so 21x+ 16.5 = 90

subtract 16.5 from each side

21x = 73.5

divide by 21 on each side

21x/21 = 73.5 /21

x = 3.5

 <span>1C. 5^3 = 125 mL 
2A. 30^3 = 27,000 mL = 27 L 
3D. 75 mm is 7.5 cm, so we do: 7.5^3 = 421.875 mL = 0.421875 L =~ 0.422 L 

Note: 
1 mL = 1 cm^3 
1 L = 1,000 mL 
10 mm = 1 cm</span>
