= 12 + (- 6)(n - 1 )
This is an arithmetic sequence with n th term
=
+ (n - 1)d
here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and
= 12, hence
= 12 + (- 6)(n - 1)
use this formula to find the 30 th term
= 12 + (- 6 × 29) = 12 - 174 = - 162
Answer:
4) measurement of angle 3 + measurement of angle 4 = measurement of angle 1 + measurement of angle 2
5) angle 1 and 4 are vertical angles
Step-by-step explanation:
Verify each statement
<em>1) angle 2 and 3 form a linear pair</em>
The statement is false
Because, angle 2 and angle 3 not form a linear pair (are not supplementary angles), angle 2 and angle 3 are vertical angles
∠2=∠3
<em>2) Angle 1 and 4 are supplementary angles. </em>
The statement is false
Because, angle 1 and angle 4 are not supplementary angles, angle 1 and angle 4 are vertical angles
∠1=∠4
<em>3) measurement of angle 1 + measurement of angle 2 + measurement of angle 3 =180</em>
The statement is false
Because
we know that
∠1+∠2=180° ------> form a linear pair (supplementary angles)
so
∠1+∠2++∠3>180°
4) <em>measurement of angle 3 + measurement of angle 4 = measurement of angle 1 + measurement of angle 2</em>
The statement is true
Because
we know that
∠1+∠2=180° ------> form a linear pair (supplementary angles)
∠3+∠4=180° ------> form a linear pair (supplementary angles)
therefore
∠3+∠4=∠1+∠2
5) angle 1 and 4 are vertical angles
The statement is true
Because
∠1=∠4 -------> by vertical angles
Answer:
He makes $1 every 2 minutes
Step-by-step explanation:
If you break it down 60 minutes is in an hour and he works for 3 hours total so you multiply 60×3 which is 180 that's how many minutes he works for. Then you take the money he made and take the minutes and divide it by the money 180÷90=2 so he make $1 every 2 minutes
