Answer:
13
4
OR
3
1
4
Step-by-step explanation:
first you work out what is in the brackets
that is
1
3
÷
1
6
to give you 2 as you answer
second step rewrite the whole question replacing two in the place of
1
3
÷
1
6
so you will have
3
4
+
2
−
(
−
1
2
)
thirdly open the brackets with the negative sign outside the bracket that is:
−
(
−
1
2
)
so that you get
+
1
2
(or
1
2
, basically)
lastly rewrite the whole question
so you will have
3
4
+
2
+
1
2
, you add all of them ...
3
4
+
8
4
+
2
4
=
13
4
EXTRA
you can keep that solution, or you can change it from improper fraction to a mixed number
if you use long division,
13
÷
4
=
3
with a remainder of
1
over
4
.
doing this by calculator you get 3.25, which is basically
3
25
100
=
3
1
4
Answer:
18.1 square inches
Step-by-step explanation:
The DVD has the shape of a circle, so its area is given by ...
A = πr² = π(2.4 in)² = 5.76π in² ≈ 18.1 in²
Finding the mean is you have to add it all up:
49+55+52+46+47+42+38= 328
The divide it by the amount of numbers so, 329/7= 47.
Subtract 47 from every number then, but even if you get a negative number you gotta keep it a positive so just ignore it if you get a negative answer when subtracting, once you do that you would add up those answers you got so;
2+8+5+1+0+5+9= 30
Then divide it again, 30/7
Which then you get the M.A.D which is 4.3, rounded to the nearest ten.
