A) 288 m2
Explanation:
Ok so surface area is just adding up all the area of each faces. Just look at what I do below:
Area of the rectangular base:
10 • 6= 60
Area of the front triangle facing us:
1/2 • 12 • 10= 60
Multiply 60 by 2 cause there is still another similar triangle at the back- 60 • 2= 120
Area of the triangle facing right:
1/2 • 8 • 6= 24
Multiply 25 by 2 case there is still another similar triangle facing on other side(left)
24 • 2= 48
Add them all up together
60 + 120 + 48= 228
MARK ME BRAINLIEST TYSM
have a nice day/night! :DD
Answer:
10x + 8
Step-by-step explanation:
If the length of one side is 5x + 2, then the perimeter of the square is
4(5x + 2) = 10x + 8
Sequence: 5/2, 5/4, 5/8, 5/16
a8=?
a1=5/2
a2=5/4
a3=5/8
a4=5/16
a2/a1=(5/4)/(5/2)=(5/4)*(2/5)=(5*2)/(4*5)=2/4=1/2
a3/a2=(5/8)/(5/4)=(5/8)*(4/5)=(5*4)/(8*5)=4/8=1/2
a4/a3=(5/16)/(5/8)=(5/16)*(8/5)=(5*8)/(16*5)=8/16=1/2
Ratio: r=a2/a1=a3/a2=a4/a3→r=1/2
an=a1*r^(n-1)
a1=5/2, r=1/2
an=(5/2)*(1/2)^(n-1)
an=(5/2)*[1^(n-1)/2^(n-1)]
an=(5/2)*[1/2^(n-1)]
an=(5*1)/[2*2^(n-1)]
an=5/2^(1+n-1)
an=5/2^n
n=8→a8=5/2^8
a8=5/256
Answers:
The formula for the general term or nth term for the sequence is an=5/2^n
a8=5/256
Answer:
I'm pretty sure its 6
Step-by-step explanation:
14-8 is equal to 6 so I'm pretty sure it would be six.
2/5=0.4, or 40%
So, 40% of the days in the year were partly cloudy.
We can find 40% of 365 by multiplying 365*0.4:
365(0.4)=146
146 days were partly cloudy.
I hope this helps ;)
