Answer:
move 5m over the sign so it is like this m-5m>-4 subract it will be-4m>-4 divide both sides by-4 m=1 negative divided by a negative is a positive

Answer:
<em>45 possible connections</em>
<em />
Step-by-step explanation:
The general equation for finding the possible number of connections in a network is given as
where n is the number of computers on the network.
for 4 computers, we'll have
= 
= 6
for 5 computers, we'll have
= 
= 10.
therefore, for 10 computers, we will have
= 
= <em>45 possible connections</em>
Answer:
394.9 cm
Step-by-step explanation:
The formula for a cone's surface area is A = π r ( r + √r^2 + h^2 ).
r = radius
h = height
The Pythagorean theorem, a^2 + b^2 = c^2, will be needed to find the height.
Plug in the values.
a(unknown)^2 + 6^2 = 15^2
A + 36 = 255
255 - 36 = 189
√189 ≈ 13.7
Surface area formula, plug in the values.
A = 3.14 × 6 ( 6 + √6^2 + 13.7^2 )
*PEMDAS*
A = 3.14 × 6 ( 6 + √36 + 187.69 )
A = 3.14 × 6 ( 6 + √223.69 )
A = 3.14 × 6 ( 6 + 14.95 )
A = 3.14 × 6 ( 20.96 )
A = 3.14 × 125.76
A = 394.8864
*round to nearest tenth*
A = 394.9 cm
Hope this helps! :)
