Answer:
Step-by-step explanation:
=> It is geometric
=> common ratio = 4
=> (-1)(4)^n-1

= -262144
Answer:
35% of the sixth grade is in the chess club
Step-by-step explanation:
if there are 100 students consider that as 100%
20 is a fifth of 100
20 x 5 =100

7 x 5 = 35
35/100 = 35%
Answer:
3.5
Step-by-step explanation:
tan60 = w/2
Multiply 2 on both sides to get the w by itself.
tan60 x 2 = w
Put tan60 into the calculator.
2 x 1.732050808 = w
Multiply.
w = 3.5
