Answer:
Plan B
Step-by-step explanation:
If you multiply 21 by $2.50 you get $52.5 then add $5 you get 57.5 and that's you outcome for Plan A
but if you multiply 21 by $1.50 you get $31.5 then add $24 you get $55.5 so the best and cheapest plan would be Plan B
Answer:
1) y = 5/2x - 3/2
2) y = 2/5x - 4/5
Step-by-step explanation:
1)
(1, 1) and (3, 6)
m = (y2 - y1)/(x2 - x1)
m= (6 - 1)/(3-1)
m= 5/2
m= 5/2
y - y1 = m(x - x1)
y - 1 = 5/2(x - 1)
y - 1 = 5/2x - 5/2
y = 5/2x - 3/2
2)
(2, 0) and (7, 2)
m = (y2 - y1)/(x2 - x1)
m= (2 - 0)/(7 - 2)
m = 2/5
y - y1 = m(x - x1)
y - 0 = 2/5(x - 2)
y = 2/5x - 4/5
So 5a=cost of adults
3s=cost of students
a+s=1142
5a+3s=4326
a+s=1142
subtract s from both sdies
a=1142-s
subsitute 1142-s for a
5(1142-s)+3s=4326
5710-5s+3s=4326
5710-2s=4326
subtract 5710 from both swides
-2s=4326-5710
-2s=-1384
dividee both sides by 2
-s=-692
multiply -1
s=692
692 students
subsittue
a+692=1142
subtract 692
a=450
s=692
a=450
Answer:
<h2>
972 pi ft^3</h2>
solution,
Volume of this composite figure
= Volume of cylinder+volume of cone
Formula to find volume of cylinder:
Formula to find volume of cone:
Use,
Here,
Radius of cone= radius of cylinder
=9 ft
Height of cylinder=10 ft
Height of cone=16 ft-10 ft=6 ft
Nowz
Volume of the figure:
Hope this helps...
Good luck on your assignment...
