Answer:
a₁ = - 256 , r = - ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
The nth term of a geometric sequence is
= a₁ ![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
Given
= - 256
, then by comparison
a₁ = - 256 and r = - ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Answer:
raoul is 16 and estaban is 22
Answer:
124°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Subtract the sum of the 3 given angles from 360
missing angle = 360° - (48 + 91 + 97)° = 360° - 236° = 124°
Answer:
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch
(0.167) shirts.
Step-by-step explanation:
Mike can stitch 7 shirts in 42 hours
to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.
He can stitch 1 shirt in =
= 6 hours
Now we calculate the work done in one hour.
He can stitch in 1 hour =
shirts or 0.167 shirts
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch
shirts.
