Answer:
15-16=-1
Step-by-step explanation:
If there are no options to choose from I’d say 25 but if there are options please post them
3.5 pound = 3 5/10 pounds = 3 1/2 pounds
Now, 1 pound = 16 ounces, so 1/2 pound = 16*1/2 = 8 oz
<span>So the answer is 3 pounds and 8 oz.</span>
Answer:
22.5
Step-by-step explanation:
You just have to do 60 divided by 2.66 (The decimal form of 2/3) and then you have your answer PLEASE BRAINLIEST
Answer: Let's assume that the pig pens need to be fenced in the way shown in the diagram above.
Then, the perimeter is given by
4
x
+
3
y
=
160
.
4
x
=
160
−

y
x
=

The area of a rectangle is given by
A
=
L
×
W
, however here we have two rectangles put together, so the total area will be given by
A
=
2
×
L
×
W
.
A
=
2
(
40
−
3
4
y
)
y
A
=

y
−

Now, let's differentiate this function, with respect to y, to find any critical points on the graph.
A
'
(
y
)
=
80
−
3
y
Setting to 0:
0
=
80
−
3
y
−
80
=

=

x
=

−

4
×

3
x
=

−
20
x
=

Hence, the dimensions that will give the maximum area are
20
by
26

3
feet.
A graphical check of the initial function shows that the vertex is at
(
26

,
1066

)
, which represents one of the dimensions that will give the maximum area and the maximum area, respectively.
Hopefully this helps!
