Answer:
The students baked 19 pies.
Step-by-step explanation:
Least total pieces of pies sold = 224
Number of pies donated by school cafeteria = 9
Number of pieces of pies donated by school cafeteria = 9×8 = 72
Number of pieces of pies baked = 224 - 72 = 152
Number of pies baked = 152 ÷ 8 = 192
Using the formulas
:
A=2AB+(a+b+c)h
AB=√(s(s﹣a)(s﹣b)(s﹣c)
)
s = (a+b+c) / 2
Solving for A:
A=ah+bh+ch+1
/2 √(﹣a∧4+2(ab)∧2+2(ac)∧2﹣b∧4+2(bc)∧2﹣c∧4)
=2·1.7+3·1.7+2·1.7+1
/2· √(﹣2∧4+2·(2·3)∧2+2·(2·2)∧2﹣3∧4+2·(3·2)∧2﹣24)
≈15.86863
Answer:
7.1
Step-by-step explanation:
Since it is a square you can use the Pythagorean theorem (a²+b²=c²) by filling in what you know. a²=5 and b²=5 so you have 5²+5²=c². This simplfies to 25+25=c². Now you simplify again to get 50=c². Finally you have to square root everything because the equation can't end in c², it has to be the most simplified it can be. This equals ≈7.1
