Sorry I have to go to baseball bye
Answer:
S infinity= -51/4
Step-by-step explanation:
First term
ar= -9
Fifth term
ar⁴= 1/3
Solving for the value of the r and a
ar= -9
ar⁴= 1/3
Dividing each other
r³=1/3 * -1/9
r³=-1/27
r= 3√-1/27
r= -1/3
Solving for a
ar= -9
a(-1/3)= 9
a= 9*-3
a= -27
Sum of a go to infinity is given by the formula
S infinity= a/(1-r)
S infinity= -27/(1-(-1/3))
S infinity= -27/(1+1/3)
S infinity= -27 * 3/4
S infinity= -51/4
Answer:
16 cities
Step-by-step explanation:
if 5days = 10 cities
8days=?
applying cross multiplication :
(8days × ten cities )÷5 day
= 16 cities
Answer:
D. cannot be determined
Step-by-step explanation:
that is kind of a trick question.
right based on the given information none of the 3 methods can be applied.
we don't have all 3 sides for SSS
we don't have 2 angles for AA
and we don't have 2 sides with their included angle for SAS.
but it can still be determined (they ARE similar), as this is a special case of SSA, where it is clear that the corresponding congruent angles are located at the same position relatively to the corresponding similar lines.
you can discuss this with your teacher, if you are interested.
AND - we can easily determine any of the other missing pieces (side and angles). these missing pieces then will correspond exactly to their counterparts in the other triangle (the 2 angles in ABC are equal to the 2 angles in DEF, the missing sides file the same scaling factor as the other known sides). and then any of the 3 methods can be applied.
so, this is actually tricky ...
Answer:
2 rooms
Step-by-step explanation:
To solve this, we need to figure out how many 14/3s go into 28/3. We know this because each room needs 14/3 rolls of wire, and we need to figure out how many rooms the electrician needs to wire with 28/3 rolls.
To find how many 14/3s go into 28/3, we can divide 28/3 by 14/3 to get
(28/3) / (14/3)
= (28/3) * (3/14)
= (28/14)
= 2
2 rooms is our answer
