Answer:

3/8

Step-by-step explanation:

The expression can be rewritten as b + 1/8 + c

substitute b and c

2 + 1/8 - 7/4 = 16/8 + 1/8 - 14/8 = 3/8

Answer:

3/8

Step-by-step explanation:

b - (-1/8) +c

Subtracting a negative is adding

b+1/8+c

Let b =2 and c = -7/4

2+1/8 - 7/4

2 1/8 - 7/4

Getting a common denominator

2 1/8 - 7/4*2/2

2 1/8 - 14/8

Changing to an improper fraction

17/8 - 14/8

3/8

A solid oblique pyramid has a regular hexagon base with an area of 54_/3 cm^2 and an edge length of 6cm. Angle BAC measures 60 d

Lady_Fox [76]

Answer: The answer is (C) 324 cubic cm.

Step-by-step explanation: As given in the question, given a solid oblique pyramid with a regular hexagonal base and area 54√3 cm². Also, the edge length of the base is 6cm and ∠BAC = 60°.

We are to find the volume of the pyramid.

The formula for finding the volume of a pyramid is given by

$V=\dfrac{1}{3}b\times h,$

where, 'b' is the base area and 'h' is the perpendicular height of the pyramid.

Here, b = 54√3 cm², h = ?

Now, from the right-angled triangle ABC, we have

$\dfrac{\textup{BC}}{\textup{AC}}=\tan 60^\circ\\\\\Rightarrow \dfrac{h}{6}=\sqrt 3\\\\\Rightarrow h=6\sqrt 3.$

Therefore, the volume of the pyramid is

$V=\dfrac{1}{3}b\times h=\dfrac{1}{3}\times 54\sqrt 3\times 6\sqrt 3=324.$

Thus, the required volume is $V=324~\textup{cm}^3.$ This makes (C) as the correct option.
