Answer:
b = 5.5
Step-by-step explanation:
In a paralelogram
A = bh
Just plug in the numbers
they said A = 60
and the number 11 is the height
60 = 11b
Divide
b = 60/11
b = 5.454545454
Answer:
28 I think
Step-by-step explanation:
12-5=7
7x4=28
Answer:
Step-by-step explanation:
surface area = 2πrL + 2πr² = 14πL + 98π
14πL + 98π = 880
14πL = 880-98π
L = (880-98π)/(14π) ≅ 55.9 cm
Start with the Pythagorean theorem{A²+B²=C², A and B are the sides and C is the Hypotenuse/Longest Side.}
2²+4²=C²
4+16=C²
20=C².....{now square root both sides.√}
√20=√C²
4.472= C
P.S.: hope I helped :)
[1], [3] => a = 49,000/2 = 24,500 => b +c = 24,500 => c = 24,500 - b;
[2] => 25*24,500 + 20b + 15c = 1,052,000 => 20b + 15c = 1,027,500;
20b + 15*(24,500 - b) = 1,027,500 => 5b = 733,500 => b = 146,700 =>
c = - 122,200;
