Answer:
By Pythagoras theorem
x² = 7² + 14²
x² = 49 + 196
x² = 245
X = square root of 245
245 is number that belongs to the green box
The student's measurement was off by an absolute error of
|2.9 cm - 2.6 cm| = 0.3 cm
The percent error in the measurement is the absolute error divided by the actual length of the string,
(0.3 cm) / (2.9 cm) ≈ 0.103 = 10.3%
His balance is $2,686.00
$2,000.00 + $1,000.00 = $3,000.00 + $450.00 = $3,450.00
$3,450.00 - (($275.00 + $40.00) + (($47.00 + $92.00) + ($101.00 + $209.00)) = $2,686.00
Answer:
I am not so clear about this question
3.14(10²) - 3.14(6²)
