Answer:
S= 4000n+50000
Step-by-step explanation: Table
50000+4000=54000 0 5000
54000+4000=58000 1 54000
58000+4000=62000 etc.. 2 58000
3 62000
Is increasing by 4000 and thats the rate of change so S=4000n
And the y intercept always will be with a 0 in the cordinates and the only with a 0 is 50000.
We put all together and it will be
Answer: S=4000n+50000
Assuming the frequency be the numbers of people, the greatest number of people should be 8, and they drank 6 glasses.
Answer:
45, 36
Step-by-step explanation:
let x y minutes be the time for pipes to fill the tank, let n be the water needed to fill the tank.
x-y=9
(n/x)*20+(n/y)*20=n
n is removed by dividing the 2nd equation by n
here u get:
(1/x+1/y)*20=1
you sub x=9+y into the above equation
1/y+1/(9+y)=1/20
((9+y)+(y))*20=(9+y)(y)
180+40y=9y+y2
y2-31y-180=0
then use the quadratic formula and u will find y=36 or -5
-5 is rejected because it is negative
x=36+9=45
therefore it is 36 mins and 45 mins
Answer:
a) x represents length?
b) 10+x=48
d) 38 inches
Step-by-step explanation:
c) 10+x=48
subtract 10 to both sides
x=48-10
x=38
