Answer: sum of the first 12 terms is

158944

Step-by-step explanation:

In a geometric series, successive terms differ by a common ratio. The formula for the sum of n terms, Sn in a geometric sequence is expressed as

Sn = a(r^n - 1)/(r - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of the terms in the sequence.

From the information given, we want to determine S12, so

n = 12

a = 4

r = 10/4 = 25/10 = 2.5

S12 = 4(2.5^12 - 1)/(2.5 - 1)

S12 = 4(59605 - 1)/1.5

S12 = (4×59604)/1.5

S12 =238416/1.5 = 158944

Find the measure of the missing value in the
kumpel [21]

Answer:

12.6

Step-by-step explanation:

The two left sides have lengths, so this allows you to establish the ratio of the lengths of the sides of the triangles,

left triangle : right triangle

ratio = 25 : 17.5

The bottom sides are also in the same ratio.

ratio = 18 : w

Write a proportion by setting the ratios equal and solve for w.

25/17.5 = 18/w

Cross multiply.

25w = 17.5 * 18

25w = 315

w = 12.6

Answer: 12.6
