12.55 of 25 is 50.2%
.5 a half is a half no matter what it is half of
25 min / 60 minDivide both sides by 5:5 / 12 =5/12 of an hour
Since any 2 points determine 1 line, take 2 of the points and find the equation of the line drawn thru these 2 points. Substitute the x and y of the either point into the equation and find the y-intercept (b) Then, substitute the x and y of the 3rd point into the equation and see if the both sides of the equation are =. (y2-y1) ÷ (x2 - x1) = slope y = slope * x + b Point # 1 = (6, 5) Point # 2 = (10, 25) Point # 3 = (12, 30) Point # 4 = (12, 35) (y2 - y1) ÷ (x2 - x1) = slope (25 - 5) ÷ (10 - 6) = slope (20) ÷ (4) = slope Slope = 5 y = m * x + b y = 5 * x + b Substitute the x and y of the point (6, 5) into the equation and find the y-intercept (b) y = 5 * x + b 5 = 5 * 6 + b 5 = 30 + b b = -25 y = 5 * x - 25 . Check your points Point # 1 = (6, 5) 5 = 5 * 6 - 25 5 = 30 - 25 OK . Point # 2 = (10, 25) 25 = 5 * 10 - 25 25 = 5 * 10 - 25 OK . Then, substitute the x and y of the 3rd point into the equation and see if the both sides of the equation are Point # 3 = (12, 30) . y = 5 * x - 25 30 = 5 * 12 - 25 30 = 60 - 25 = 35 Point # 3 = (12, 30) is not on the line . . Point # 4 = (12, 35) 35 = 5 * 12 - 25 35 = 60 - 25 =35 Point # 4 = (12, 35) is on the line
12 and a half (12.5)half of 25 = 25/2 or 12 1/2 or 12.5
2½/12½ × 100 % = (2×2½)/(2×12½) × 100 % = 5/25 × 100 % = 1/5 × 100 % = 20 %
5 OR -5 (though 5 is generally the accepted answer) 25 to the half power is the same as radical(25).
5.5/2 5/2 is 2.5 and .5/2 is .25 2.5+.25=2.75
half of 5/6 is 5/12
No! .5 is one half.
.25+.25=.5
3(4y+5) = 25 3 . 4y + 3 . 5 = 25 12 y + 15 = 25 12 y = 25 - 15 12 y = 10 y = 12:10 = 1.2
It is: 25/60 = 5/12 simplified
