Answer:
answer is 90 for first term
Step-by-step explanation:
Let the terms be
First term x
We will use the formula s∞=x/1−r to find the sum of an infinite geometric series, where −1<r<1.
We know the sum and the common ratio, so we'll be solving for x where r =4/5
s∞=x/1−r
450=x/1−4/5
450=x/1/5
450=5x
x=90
this is the first term x1 = 90
we know that common ratio is 4/5, so multiplying the first term by factor 4/5 to get the second term
90 x 4/5= 72 second term
Answer:
<h2> 6/35</h2>
Step-by-step explanation:
This problem is on fraction
given data
chocolate chip cookies= 12
lemon cookies = 6
strawberry cookies= 17
the total cookies is = 12+6+17
=35 cookies
Therefore the fraction that indicates the lemon cookies is
=the number of lemon cookies/total cookies
=6/35
Hence the fraction lemon is 6/35
