Use the surface area formula of a rectangular prism to find the width. (I have changed it to use the same terms given in the problem).
A
=
2
(
d
w
+
h
w
+
h
d
)
Because of the given information, it is known that:
A
=
208
h
=
8
d
=
6
The width is not know, so let it keep it's variable
w
. But substitute the other values into the equation:
A
=
2
(
d
w
+
h
w
+
h
d
)
208
=
2
[
6
w
+
8
w
+
(
8
)
(
6
)
]
208
=
2
(
14
w
+
48
)
Use the distributive property to solve the right side of the equal sign:
208
=
2
(
14
w
+
48
)
208
=
28
w
+
96
112
=
28
w
112
28
=
w
4
=
w
The width is
4
.
Answer:
where is the table?
Step-by-step explanation:
Answer:
Step-by-step explanation:
5 miles + 16 miles = 21 miles
each mile is 2.50
21 x 2.50 = 52.50
trip is 4.50
52.50 + 4.50 = 57
Answer:
1/2 is the simplified fraction for 3/6.
Step-by-step explanation:
im not sure but i think thats it
Part/Whole=Percent/100
Part=26
Whole=30
Percent= Variable because that is what you want to find out
So now it is 26/30=X/100
You then cross multiply and you get
2600=30X
Divide by 30 and your answer is 86.66667. She got 86.66667% of her questions right. I am not sure if you need to round that or not.
Another way you can do it is Divide 26÷30=.866667 and then multiply by 100 to get 86.66667.
