Step-by-step explanation:

m < QRS = m < URS + m < QRU

30x - 4 = 60° + 15x - 4

15x = 60°

X = 4°

<u>m < QRS</u> = 30 * 4 - 4 = <u>116°</u>

5) Alex's house (point F) lies on the same street as her school (point H). Alex's bus stop (point G) lies between her

vlada-n [284]

Answer:

100 meters

Step-by-step explanation:

Given the following :

Alex house = F

Alex school = H

Alex bus stop = G

FG = 2x meters

GH = 1000meters

FH = 1200 meters

Hence,

FH = FG + GH

1200 = (2x + 1000) meters

1200 = 2x + 1000

1200 - 1000 = 2x

200 = 2x

x = 100meters

Hence, x = 100 meters

Determine whether each of the following sequences are arithmetic, geometric or neither. If arithmetic, state the common differen

PilotLPTM [1.2K]

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Let's see if the sequence is Arithmetic or Geometric :}$

$\textsf{If the ratio between successive terms is }$ $\textsf{equal then, the terms are in GP}$

$\sf{ \dfrac{12}{-4} = -3}$

$\sf{ \dfrac{-36}{12} = -3}$

$\textsf{Since the common ratio is same, }$ $\textsf{we can infer that it's a geometric progression}$ $\textsf{with common ratio of -3}$

Find the 7th term of the geometric sequence with the given terms.

ohaa [14]

Answer:

1. 1458

2. 500 or -500

Step-by-step explanation:

1. a4=54, a5=162

r = 162/54 = 3

a7 = a5 × r²

= 162 × 3² = 1458

2.a4=-4, a6=-100

r² = -100/-4 = 25

r = +/- 5

a7 = a6 × r

= -100 × +/- 5

= +/- 500
