Answer:
$5
Step-by-step explanation:
Just use simultaneous equations to solve this problem.
Let cost of pens = x and cost of pencils = y:
217 x + 131 y = 913
131x + 217y = 827
Solving these 2 equations you get: x = 2 and y = 3
Hence, cost of one pen and one pencil = 2 + 3 = 5 rupees
Step-by-step explanation:
the volume of the tent (triangular prism) is:
v = 1/2*b*h*l
v = 1/2*8*7*9
v = 252 ft^3
Answer:
1. 160cm²
2. 176.25cm²
3. 33.75ft²
Step-by-step explanation:
Area triangle = (1/2)(base)(height)
1)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(8)(9))+2(0.5(8)(11))
=72+88=160cm²
2)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(7.5)(7.5))+2(0.5(7.5)(16))
= 56.25 + 120 = 176.25cm²
3)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(4.5)(2.5))+2(0.5(4.5)(5))
= 11.25+22.5 = 33.75ft²
You can use a calculator, or use long division
