Volume of Big Pyramid= 324 cubic feet

Volume of small pyramid= 12

Volume of a pyramid is given as V=⅓xBasexheight

For the big pyramid

324=⅓xbasexheight

But 324= 27x12

Then for the big pyramid,

12=1/3x1/27xbasexheight

For the small pyramid

12=1/3xbasex6

Since both base are similar and from the equations derived so far

1/3x1/27xheight=1/3x6

Height=27x3x1/3x6=162feet

ACCORDING to the rate of electricity charge, the minimum charge up to 20 unit is Rs 80 and the cost per unit from 21 units to 25
azamat

Answer:

180

Step-by-step explanation:

let x = total units of electricity after 250 units

the total units of electricity consumed can be determined using the formula below

80 + 7.3x = 1248

7.3x = 1248 - 80

7.3x = 1168

divide both sides of the equation by 7.3

x = 1168 / 7.3

x = 160

total electricity consumed = 160 + 20 = 180

160

Solve for x.4(2x + 3) = 3x + 3 + 2x
ElenaW [278]

Answer:

The value of x is -3.

Explanation:

Given the equation:

4\mleft(2x+3\mright)=3x+3+2x​

Step 1: Distribute 4 in the left-hand side.

\begin{gathered} 4\mleft(2x)+4(3\mright)=3x+3+2x​ \\ 8x+12=3x+2x​+3 \\ 8x+12=5x​+3 \end{gathered}

Step 2: Collect like terms.

\begin{gathered} 8x-5x=3-12 \\ 3x=-9 \end{gathered}

Step 3: Divide both sides by 3.

\begin{gathered} \frac{3x}{3}=-\frac{9}{3} \\ x=-3 \end{gathered}

The value of x is -3.

Tan = opposite/ adjacent

tan 60 = v/14

14 tan 60 = v

v = 24.24871.....

v = 24.2 (nearest tenth)



cos = adjacent / hypotenuse

cos 60 = 14/u

u = 14/cos 60

u = 28
