Step-by-step explanation:
the number of pupils are in the lower school
= (1- 1/5 - ¼) × 600
= (20/20 - 4/20 - 5/20)×600
= (11/20) ×600
= 330 pupils

x = 1040/43 = $24.19 per day.
y = 10/43 = $0.23 per mile.
Try this solution:
The correct answer is 'a' only, where x= -4;-1 and y= -6;-21
Given
s=16t^2
where
s=distance in feet travelled (downwards) since airborne with zero vertical velocity and zero air-resistance
t=time in seconds after release
Here we're given
s=144 feet
=>
s=144=16t^2
=>
t^2=144/16=9
so
t=3
Ans. after 3 seconds, the object hits the ground 144 ft. below.
Answer:
125 pages
Step-by-step explanation:
we can use a proportion
3/5=75/x
multiply cross so 75×5 and 3×X
375=3x
÷3. ÷3
x=125
check
75/125=simplified is 3/5
