<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: (3t-2)^2
Step-by-step explanation:
Well, multiply 9 and 4 together to get 36.
Now what factors of 36 add to 12? Well, 6 and 6, so let's rewrite this:
9t^2-6t-6t+4
Now group factor what you can:
3t(3t-2)-2(3t-2)
Now 3t and -2 both share the common factor of (3t-2) so you can rewrite it as:
(3t-2)(3t-2) which is:
(3t-2)^2.
Hope that makes sense or helps!
