Answer: A is 40ft3
B is 76ft3
Step-by-step explanation:
A is Volume. V= LxWxH
V=5 x 2 x 4
V= 40ft3
B is surface Area. 5x2= 10
2x4=8
4x5=20
10+8+20=38
38x2= 76ft3
Answer:
60.5m^2
Step-by-step explanation:
the area of the square
=11m×11m
=121m^2
the area of triangle
=11m×11m÷2
=121m^2÷2
=60.5m^2
the area of the shaded region
=121m^2-60.5m^2
=60.5m^2
the answer is not very sure,
if it is wrong, i am sorry for it.
im doing this problem right now---
ok so a1=256 a2=64 a3=15 a4=4... find a9
the sequence divides by 1/4 every term
an=a1*r^n-1
an=(256)*(1/4)^n-1
replace n with 9
A9=(256)*(1/4)^9-1
A9=(256)*(1/4)^8
=(256)*(1/4)
A9=64^8
1/256 or a9= 0.00390625
A squared + b squared = c squared
8.6^2+14.7^2=c^2
73.96+216.09=c^2
square root both sides and...
c=17.03085
Your answer is A
Hope this helps
