<u>Answer:</u>
(i) Total cost of the flat is Rs. 540000.
(ii) Expenditure incurred on labour is Rs. 150000
<u>Step-by-step explanation:</u>
According to the question, cement cost is Rs. 112500, which represents 75° in the pie chart.
(i) The total cost of the flat is represented by the total 360° in the pie chart.
∴ Using unitary method
75° represents Rs. 112500
⇒ 360° represents =
× 360
= Rs. 540000
∴ Total cost of flat = Rs. 540000
(ii) Similarly, to calculate the cost of labour, represented by 100° in the pie chart, we can use the unitary method:
75° represents Rs. 112500
⇒ 100° represents =
× 100
= Rs. 150000
∴ Cost of labour = Rs. 150000
Answer:
16
Step-by-step explanation:
divide 128 from 8
By creating two right triangles (one for depression and one for elevation) and by using 700 as the adjacent side, you can use tangents to find the opposite sides and add them together.
Tan(45) = opposite side/700 or 700tan(45) = opposite side (elevation).
This of course equals 700.
Then do the same for the depression.
Tan(32) = opposite side/700 or 700tan(32) = opposite side (elevation).
Which equals 437.4.
Adding the two together and you get the height of the cell tower at 1137.4ft
