Well if the room is square then you ned to find the square root of the area.
Find 
Answer:
6x-108
Step-by-step explanation:
-3 · 2(7 · 2 - x + 4)
= ((−3)(2))((7)(2) +− x + 4)
= −84 + 6x − 24
= 6x − 108
The answer is 6x - 108
Given:
Radius of the cone = 3 inches
Height of the cone = 8 inches
To find:
The volume of the cone, in terms of π.
Solution:
We know that, the volume of a cone is:

Putting
, we get




Therefore, the volume of the cone is
.
Answer:
30%
Step-by-step explanation:
One simple way of finding out discounts is to simplify our answer by starting with 10% and subtracting from that.
If the original price were to have a 10% discount, it would be 4.70/10 for .47 per 10% off.
10% gives us 4.23, so let's take another 10% off by doing 4.23-.47, which is equal to 3.76. While lower, it's not our answer so lets do another 10%
3.76-4.7 = $3.29
With a total of 3 10%'s taken off, or in this case, 30% off, we can conclude that the discounted prices of $3.29 is 30% of the original price.
Answer: Exponential decay model:
y
=
x
(

−
r
)
t
, half life of tablet is about
2
hours and after
t
=
3
hours , remaining drug on patient's system is
42.875
mg.
Step-by-step explanation: Initial drug
x
=
125
mg ; rate of decay
r
=

100
=
0.3

Exponential model:
y
=
x
(

−
r
)
t
=
125
(
1
−
0.3
)
t
=
125
⋅
0.7
t
Half life:
y
=

mg
∴
62.5
=

⋅
0.7
t
or
0.7
t
=

. Taking logarithm on both sides we get ,
t

=
log
(

∴
t
=
log
(

)
log
(

The half life of tablet is about
2

y
=

t
=
