Here,
cost of 3 handkerchiefs = Rs.2.29
Cost of 1 handkerchief = 2.29 ÷ 3
= Rs. 0.763
Therefore, cost of handkerchief per dozen = Rs. 0.763 × Rs.12
=Rs.9.156
You would make a fraction with circles on the top which would be 76. Then you would add 22 to 76 and get 97 because that is the number of all of the shapes. That would mean your fraction would be 76/97. If u want to simplify that is up to you.
Answer:
it would be the second option.
the slant height would be the hypotenuse of a right triangle. 1/2 the length of the base would be one side of a right triangle. Use the Pythagorean theorem to find the height:
89.9^2 = 9.9^2 + x ^2
8082.01 = 98.01 + x^2
X^2 = 8082.01-98.01
X^2 = 7984
X = sqrt(7984)
X = 89.35
Round to 89.4
