I'm not so good but I think thatmeans r is a different number and its half of 14 so figure out an equation

The floor plan shows an l shaped room. Shane wants to buy carpet for the room. The cost for one square foot of carpet is $4. Wha

VashaNatasha [74]

The area of shape is the amount of space on it.

The cost to carpet the room is $224

From the floor plan (see attachment), we can divide the room into two shapes:

A 8ft by 6ft rectangle
A 4ft by 2ft rectangle

So, the area of the floor plan is:

$\mathbf{Area = 8ft \times 6ft + 4ft \times 2ft}$

$\mathbf{Area = 48ft^2 + 8ft^2}$

$\mathbf{Area = 56ft^2}$

The unit cost of carpet is $4 per one square foot

So, the cost to carpet the room is:

$\mathbf{Cost = \$4 \times 56}$

$\mathbf{Cost = \$224}$

Hence, the cost to carpet the room is $224

What is an equivalent to -16m^2n-(-25m^2n)+(-7m^2n)

pantera1 [17]

Answer:

The equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$

Step-by-step explanation:

Given the expression

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a$

$=-16m^2n+25m^2n-7m^2n$

$\mathrm{Add\:similar\:elements:}\:-16m^2n+25m^2n-7m^2n=2m^2n$

$=2m^2n$

Therefore, the equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$

Water is leaking out of an inverted conical tank at a rate of 11600.011600.0 cubic centimeters per min at the same time that wat

Anarel [89]

Answer:

Win=436584.2477 cm3/min

Step-by-step explanation:

Volume for a conical tank

V=π/3 r^2 h

We need a relation between r and h

r/h=252.5/1301.3=0.194 --> r=0.194h

sust. in Volume equation

V=π/3 (0.194r)^2 h=0.0394h^3

taking derivative with time respect in both sides

dV/dt=3(0.0394) h^2 dh/dt and we know when h=404cm, dh/dt=22.022 cm/min

dV/dt=3(0.0394)(404)^2 (22.022)=424984.2477 cm^3/min

Also, we know

dV/dt=Win-Wout and Wout=Win-11600.01160

Finally

Win=424984.2477+11600.0116

Answer

Win=436584.2477 cm3/min
