Answer:
15x+55y+20
Step-by-step explanation:
mark me brainlest
Sn=sum of the n terms of the geometric sequence.
a= the first term
r=the common ratio
n=numbers of terms.
Sn=a[(1-r^n)/(1-r)]
In this case:
a=-3
r=a₂/a₁=15/-3=-5
n=9
S₉=-3[(1-(-5)⁹) / (1-(-5))=
S₉=-3(1+1953125)/6)=
S₉=-3(1953126/6)=
S₉=-3(325521)
S₉=-976563

Answer:
10 sculptures
Step-by-step explanation:
He makes 1 sculpture for every 5 paintings. We can break it down like this to simplify:
We know that if he made 50 paintings in total, thats 10 groups of five paintings (5x10=50)
For every group of 5 paintings, he makes one sculpture
So if there are 10 groups of five paintings, he made 10 sculptures.
Answer:
hope it is helpful

orignal vale is 20
so
increase %=increase in orignal value/orignal value ×100
=10/20×100=50%
