L = 15m = 1500cm
b= 30cm
h= 4m= 400cm
So, total volume of the wall= l×b×h
= 1500×30×400= 1,80,00,000 cm^3
Now, volume of one brick= 22×12.5×7.5= 2062.5 cm^3
Volume of wall containing only bricks= total volume of the wall - volume of wall containing mortar
= 1,80,00,000 - (1,80,00,000 × 1/12)
= 1,65,00,000 cm^3
So, no. of bricks = volume of wall containing bricks ÷ volume of one brick
= 1,65,00,000 ÷ 2062.5
= 8000 bricks.
Answer:
x=4
Step-by-step explanation:
7/9 - x/9 = 1/3
I like to get rid of fractions so I will multiply each side by 9
9*(7/9 - x/9) = 1/3*9
7 - x = 3
Subtract 7 from each side
7-x-7 = 3-7
-x= -4
Multiply each side by -1
x =4
The approximate value of x = 0.92
The number is 14. You can put it in an equation by writing 14 + (14 ÷ 2) = 21
U have to show the graph first then we can find it
