A room is 20 feet long, 12 feet wide, and 10 feet high. What is the maximum distance from one corner to another

exis [7]

Answer:

25.38

Step-by-step explanation:

Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.

20^2+12^2=c^2

400+144=544=c^2

c= $\sqrt{544}$

then find corner of floor to opposite roof corner.

100+544=644=c^2

c= $\sqrt{644}$

so its about 25.38 feet

A circle with radius \pink{6}6start color #ff00af, 6, end color #ff00af has a sector with a central angle of \purple{48^\circ}48

alexandr1967 [171]

Answer:

Therefore,

The area of the sector is 15.09 unit².

Step-by-step explanation:

Given:

Circle with,

radius = r = 6 unit

central angle = θ = 48°

pi = 3.143

To Find:

Area of sector = ?

Solution:

If 'θ' is in degree the area of sector is given as

$\textrm{Area of Sector}=\dfrac{\theta}{360}\times \pi r^{2}$

Substituting the values we get

$\textrm{Area of Sector}=\dfrac{48}{360}\times 3.143\times 6^{2}$

$\textrm{Area of Sector}=15.0864=15.09\ unit^{2}$ rounded to nearest hundredth

Therefore,

The area of the sector is 15.09 unit².

Solving Rational equations. LCD method. Show work. Image attached.

Ugo [173]

Answer:

$k=\frac{1}{2}$

Step-by-step explanation:

The given rational equation is

$\frac{5k}{k+2}+\frac{2}{k}=5$

The Least Common Denominator is

$k(k+2)$

Multiply each term by the LCD.

$k(k+2)\times \frac{5k}{k+2}+k(k+2)\times \frac{2}{k}=5k(k+2)$

Simplify;

$k\times \frac{5k}{1}+(k+2)\times \frac{2}{1}=5k(k+2)$

$\Rightarrow k(5k)+2(k+2)=5k(k+2)$

Expand;

$\Rightarrow 5k^2+2k+4=5k^2+10k$

Group similar terms;

$\Rightarrow 5k^2-5k^2+2k-10k=-4$

$\Rightarrow -8k=-4$

Divide by -8.

$k=\frac{1}{2}$
