What’s the volume of the pyramid
ValentinkaMS [17]

Answer:

The volume of the given pyramid is 300 cm³

Step-by-step explanation:

The volume of a pyramid, V_{pyramid}, is given as follows;

V_{pyramid} = \dfrac{1}{3} \times Base \ area \times Height

The height of the pyramid = 12 cm

The side length of the square base of the pyramid = 5 cm

The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²

Therefore, by substitution, we have;

V_{pyramid} = \dfrac{1}{3} \times 25 \ cm^2 \times 12 \ cm = 300 \ cm^3

The volume of the given pyramid, V = 300 cm³.

Solve for x. 5 x − 19 ≤ 1 OR − 4 x + 3 &lt; − 6
k0ka [10]

5x - 19 \leqslant 1

change

\leqslant  \: to \:  =

given you

5x - 19 = 1

making x the subject by transferring the -19 to the right hand side of the equation

5x = 19 + 1

5x = 20

dividing through by 5

\frac{5x}{5}  =  \frac{20}{5}

x = 4

{{x:x  \leqslant 4}}

also given

- 4x + 3 < -  6

change the operation sign to =

- 4x + 3 =  - 6

- 4x =  - 6 - 3

- 4x =  - 9

dividing through by -4

\frac{ - 4x}{ - 4}  =  \frac{ - 9}{ - 4}

x =  \frac{9}{4}

so the truth set is

{x:x>9/4}.

The < sign changes to > because we divided by a negative number when solving for x

D/18 + 3 = 3d/54 + 22
Anestetic [448]

Answer:

But this condition is not feasible so, from given equation the value of D is not determine

Step-by-step explanation:

Given equation is :

\frac{d}{18} +3 = \frac{3d}{54} + 22

\frac{d}{18} - \frac{3d}{54} = 22 - 3

Or, \frac{3d -3d}{54} = 18

Or    0 = 18

But  0 ≠  18

but this condition is not feasible so, from given equation the value of D is not determine   .. Answer
