V1=30km/hr
v2=20km/hr
v=2v1v2/(v1+v2)
=2*30*20/(30+20)
=24km/hr
Answer:
10
Step-by-step explanation:
Given that:
Point X = (3, 2)
Point Y = (3, - 8)
Distance of point X to Y:
Distance = √(x2 - x1)^2 + (y2 - y1)^2
X1 = 3 ; y1 = 2 ; x2 = 3 ; y2 = - 8
Distance = √(3 - 3)^2 + (-8 - 2)
Distance = √(0)^2 + (-10)^2
Distance = √0 + 100
Distance = √100
Distance = 10
Hey there! :)
Answer:
24 pages.
Step-by-step explanation:
Calculate how many pages 75% of 96 is:
96 × 0.75 = 72 pages.
Find how many pages do not have ads by subtracting the amount that have ads from the total:
96 - 72 = 24 pages.
Therefore, 1/4 of 96 or 24 pages do not have ads.
