A=30^2+ 2 x 30 x 26
A= 900 + 1560
A= 2460
so the surface area is 2460
v=1/3 x 30^2 x 26
v=1/3 x 900 x 26
v= 300 x 26
v=7800
so the volume is 7800
and the way the order of operations helped you is that you had to remember to always do the exponents before any of the other multiplication
Answer: 1967
Step-by-step explanation:
Ada was 15 years when her sister Ngozi was 18 years.
This means that Ngozi is older than Ada by:
= 18 - 15
= 3 years
If Ngozi is older by 3 years, this means that she must have been born 3 years earlier than Ada
If Ada was born in 1970, Ngozi was born:
= 1970 - 3
= 1967
Answer:
80.
Step-by-step explanation:
x^2y^3 * x^3y^2
= x^(2+3)y^(3+2)
= x^5y^5 and as x^2y^3 = 10 and x^3y^2 = 8 we have:
10 * 8
= 80.
At the second concert, there were 217% more people than in the first concert.
