Answer:

\large\boxed{a)\ A\approx93.53\ in^2}\\\boxed{b)\ 8,640\ in^2}

Step-by-step explanation:

a)

The formula of an area of a regular hexagon:

A=6\cdot\dfrac{a^2\sqrt3}{4}

a - side length

We have a = 6in. Substitute:

A=6\!\!\!\!\diagup^3\cdot\dfrac{6^2\sqrt3}{4\!\!\!\!\diagup_2}=3\cdot\dfrac{36\!\!\!\!\!\diagup^{18}\sqrt3}{2\!\!\!\!\diagup_1}=3\cdot18\sqrt3=54\sqrt3\ in^2\\\\A\approx93.53\ in^2

b)

5ft=5(12in)=60in\\\\12ft=(12)(12in)=144in

The area of a hallway:

A=(60)(144)=8,640\ in^2

Here’s Question three
Hitman42 [59]

Answer:

BD = 3 units

Step-by-step explanation:

Since, AD is an angle bisector of ∠BAC,

m∠BAD = m∠CAD = 20°

CD = 3 units

In ΔACD and ΔABD,

m∠BAD = m∠CAD = 20° (Given)

AD ≅ AD [Reflexive property]

Therefore, by H-A property of congruence both the triangles will be congruent.

And by CPCTC,

CD ≅ BD = 3 units

Your history test is out of 30 points. How many points would you need to get if you wanted a ‘B’ or higher? (Hint: A grade of 80
Sloan [31]
To get a B, you need at least 80%.

30 x 0.8 = 24

80% of 30 is 24, so you would need to get at least 24 points <3
