First you need to make X = to the whole number 
So add .75x to the other side to get 1.4x the divide it by 18.5

Question: Antonio is working with a new geometric series generated by the equation A(n)=20(1.1)^n-1.His sister challenged him to
Mekhanik [1.2K]

Answer:

sum of 22nd = 1,428.05

sum of 23 to 40 is 932.53

Step-by-step explanation:

A(n)=20(1.1)^n-1

20 is the first term or a1

1.1 is the common ratio or r

A(22) = 20(1.1)^22-1

22nd term = 20(1.1)^21

22nd term = 148.00

sum of geometric sequence

formula

Sn = a1(1-r^n)/1-r

Sn = sum

a1 = first term

n = number of term

r = constant ratio

sum of 22nd = 1,428.05.

23 to 40 is 17 terms

Sequence: 23, 25.3, 27.83, 30.613, 33.6743, 37.04173, 40.745903 ...

The 17th term: 105.684378686

Sum of the first 17 terms: 932.528165548

Whats the value of x and what is the length of side UW
solmaris [256]

We will calculate this by using ratios and because these two triangles are similar, which is very important.

Explanation:

We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.

9 : 21 = 18 : x

x = (21*18)/9

x = 378/9

x = 42.

The correct answer is B. 42.
