Answer:
8.5 hours
Step-by-step explanation:
Okay, so he made $71 last week including his $20 allowance. We can take out the allowance 71-20= 51 dollars made from babysitting. But they are asking us to find how many hours he worked.. knowing he gets paid $6 an hour we can divide 51/6 = 8.5 hours babysitting.
Hope this helps :)
Surface area
break it down
bottom and top
bottom=5 rectangle
top=2 triangles+2rectangle
areas
area of recatngle=lw
area of traignle=1/2lw
so total is
SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8)
(I'm not going to do all the math, just the result)
SA=178.08 yd^2
split the figure into 2 parts
top and bottom
bottom=rectagular prism=lwh
top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so
bottom=8 times 2.8 times 4.8=107.52
top=1/2 times 8 times 3 times 2.8=33.6
add them
107.52+33.6=141.12 yd^3

Answer:
LHS = 
= RHS =
Step-by-step explanation:
Data provided in the question:
a = −1 + √3i and b = 2
to prove:
Considering the LHS
⇒ 
substituting the value of a and b, we get
⇒ 
or
⇒ 
on multiplying and dividing by conjugate ( 1 - √3i )
we get
or
or
(as (√i)² = -1 )
or
Now,
considering the RHS
substituting the value of a and b, we get
⇒ 
or
⇒ 
or
⇒ 
or
⇒ 
now,
on multiplying and dividing by conjugate ( -1 - √3i )
we get
or
or
or
or
or
or
or
Since, LHS = RHS
hence satisfied
