Answer:
The geometric series is given by:
Step-by-step explanation:
We are given the following in the question:
The numbers of teams remaining in each round follows a geometric sequence.
Let a be the first term and r be the common ratio.
The term of a geometric sequence is given by:
There are 16 teams remaining in round 4 and 4 teams in round 6.
Thus, we can write:
Dividing the two equations, we get,
Putting value of r in he equation we get:
Thus, the geometric sequence can be written as:
I don’t want to sound d u m b but use photomath it really helped me with quadratic formula it shows steps too.
Answer:
50 square units .
Step-by-step explanation:
Given :
Image of letter E with height of 12 and width of 10
inside space of height of 5 and width of 7
To find : Area
Solution :
First calculate the area of rectangle ABKL = length *width = 12*10 = 120 square units
Now subtract the area of rectangle CDFE and HGJI from the rectangle ABKL to get the area of given figure
Area of CDEF = Area of HGJI since the length and width of the rectangles is smae
Thus Area of CDEF = length *width =5*7 = 35 square units
Thus the Area of HGJI = 35 square units
Now subtract the area of both rectangles from the area of ABKL
⇒120-(35+35)= 50 square units .
Thus the area of given figure LETTER E = 50 square units .
