Answer:
Rs. 4,200,000
Step-by-step explanation:
Given :
Volume of brick = 500cm³
Dimension of wall : 200m×0.5m×1.5m
Converting to cm
Volume of compound wall:
(200 * 100) * (0.5 * 100) * (1.5 * 100)
20000cm * 50cm * 150cm=
= 150000000cm³
Volume of compound wall / volume of brick
1500000000 cm³ / 500 cm³
= 300000
Price per brick = Rs. 14
Total price = 14 * 300000 = Rs. 4,200,000
Answer:
70
Step-by-step explanation:
180 -(60+65) = 180 - 125 = 55
180 - (50 + 55) = 180 - 105 = 75
180 - (35 + 75) = 180 - 110 = 70
Answer:
Number line 2 shows -6 and its opposite.
Step-by-step explanation:
The opposite of -6 is 6 so all you have to do is find the number line that shows -6 and 6. Hope this helps! Have a great day!
Answer:
1. Western erodes 2 ft/yr; Dunes builds up at 5 ft/yr
2. Sometime in 2006
3. Solve simultaneous equations
Step-by-step explanation:
1. Erosion patterns
(a) Western Beach
In 15 yr, Western Beach erodes from 100 ft to 70 ft.
The rate of erosion is 30 ft/15 yr = 2 ft/yr.
(b) Dunes Beach
In 15 yr, Dunes Beach builds up from 20 ft to 95 ft.
The rate of buildup is 75 ft/15 yr = 5 ft/yr.
2. Beaches with equal width
From the table, it appears that the beaches will have the same width sometime in year 11 (2006).
3. Best approximation
The graph below also shows that it happens part way through year 11 (2006).
We could get an even better solution by calculating the equations of the two lines and solving the simultaneous equations.
Well, apologies if this is wrong but in my opinion, I think it's that The angles do not change. This is because the angles are alright staying in the same place. I don't understand much about angles but it makes the most sense to me.
