<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:
45 units
Step-by-step explanation:
See the given diagram with the question here.
The point D and point E are the midpoints of line segments AC and BC respectively.
Therefore, the length of the line joining points D and E will be half of length AB.
Now, given that AB = 11x - 25 and DE = 4x + 1.
Hence, ( 11x - 25 ) = 2 ( 4x + 1 )
⇒ 3x = 33
⇒ x = 11
Therefore, length DE = 4x + 1 = 4 ( 11 ) + 1 = 45 units. (Answer)
3 Pairs of leggings. $12(cost of leggings)x3= 36 +5 (flat rate)=41
These are the steps, with their explanations and conclusions:
1) Draw two triangles: ΔRSP and ΔQSP.
2) Since PS is perpendicular to the segment RQ, ∠ RSP and ∠ QSP are equal to 90° (congruent).
3) Since S is the midpoint of the segment RQ, the two segments RS and SQ are congruent.
4) The segment SP is common to both ΔRSP and Δ QSP.
5) You have shown that the two triangles have two pair of equal sides and their angles included also equal, which is the postulate SAS: triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles.
Then, now you conclude that, since the two triangles are congruent, every pair of corresponding sides are congruent, and so the segments RP and PQ are congruent, which means that the distance from P to R is the same distance from P to Q, i.e. P is equidistant from points R and Q
