A)4^(n+3)=8^14
2^(2×(n+3))=2^(3×14)
2^(2n+6)=2^42
2^2n=2^36
n=18
b) (assuming a : is divide)
3^(2n+1)=9^17/3^3
3^(2n+1)=3^(2×16)/3^3
3^(2n+1)=3^29
3^2n=3^28
2n=28
n=14
d) (6^n)^4×36=216^10
6^4n×6^2=6^(3×10)
6^(4n+2)=6^30
6^4n=6^28
4n=28
n=7
e)7^(n^2)÷7=49^24
7^(n^2-1)=7^(2×24)
7^(n^2)=7^49
n^2=49
n=7
g)15^(n+4)÷5^(n+4)=81^6
3^(n+4)×5^(n+4)÷5^(n+4)=3^(4×6)
3^(n+4)=3^24
n=20
h)81^n÷9^n+9^(n+2)÷9=90÷9^6
9^2n÷9^n+9^(n+2)÷9=9*10/9^6
9^n+9^(n+1)=10/9^5
I don't know where to go from here
I)what?
Answer:
No she isnt
Step-by-step explanation:
12.5% is for a hour, so if Maxine did 3 hours more than that would be (12.5x 3 ) 37.5%
Answer:
562 + x ≥ 650
x ≥ 88
Step-by-step explanation:
He has 562 points. He needs x points to get an A. He must get at least 60 points to get an A.
562 + x ≥ 650
To solve this, we subtract 562 from each side
562-562 + x ≥ 650-562
x ≥ 650-562
x ≥ 88
Answer:
area of the rectangle =length *breadth
=14*5=70sq.ft
diameter =6ft
radius =3ft
area of the semi circle =1/2πr^2
=1/2*22/7*3*3=14.142sq.ft
area of the figure =area of the rectangle +area of the semi circle =70+14.142=84.142sq.ft
Answer: 64
