Answer:
216 boys
Step-by-step explanation:
450 students: 20% girls, 80% boys
450*20%=90 girls
450*80%=360 boys
Students having mobile phones: 40% (OF THE 90) girls, 60% (OF THE 360) boys
90*40%=36 girls
360*60%=216 boys
[We honestly don't need to care about the girls without mobile phones as they are only asking how many boys have mobile phones]
B= Exactly one solution
-6y+9y= 3y
3y+13=8y-3
3y=8y-16
-5y=-16
The minutes will be ur x axis and the cm of snow will be ur y axis
(10,2),(30,3.6).....using 2 points and the slope formula : (y2 - y1) / (x2 - x1)
slope = (3.6 - 2) / (30 - 10) = 1.6 / 20 = 0.08 cm per minute <===
Step-by-step explanation:
1.6a= -9.12
a= -9.12/1.6
=−5.7
option B
