Firstly, It says that the two triangles are similar .
The scale factor is 2 as 12 / 6 = 2
25 + 85 = 110
180 - 110 = 70.
70 degrees
Answer: First off thats not how you ask for help, by calling us "smart math people" that could offend someone...Second off the answer is 10 because
Step-by-step explanation:
A^2 + B^2 = C^2
6^2 + 8^2 = C^2
36 + 64 = 100 square root that = 10
Answer: 10
Answer: 2.5%
Step-by-step explanation:
Mean score = 65
Standard deviation = 5
Score (x) = >75
Z-score = [(score - mean) ÷ standard deviation]
Z - score = [(75 - 65) ÷ 5]
Z - score = 10 ÷ 5 = 2
P(score higher than 75) = 100 - 95 = 5/2 = 2.5%
Answer:
see explanation
Step-by-step explanation:
Given the recursive formula
=
and
= 2
=
, then
=
( multiply both sides by 4 )
a₃ = 4 ×
= 9
= 9 ( multiply both sides by 4 )
a₂ = 36
= 36 ( multiply both sides by 4 )
a₁ = 144
The first 4 terms are
144, 36, 9, 2
