Answer:
$812.5
Step-by-step explanation:
Given: Ethan need to save at least $500.
He has saved so far $175
Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.
Lets assume Ethan´s paycheck amount be "x"
First finding the remaining amount to be covered.
Remaining amount= 
∴ The remaining amount to be covered is $325.
As given, Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.
Now, using the inequality to find the amount of paycheck.
⇒ 
multiplying both side by 5
⇒ 
divinding both side 2
⇒ 
∴ 
Hence, Ethan must make at least $812.5 in his paycheck to cover his remaining anount to buy dirt bike.
V=hpir^2
d/2=r
so, at first, diameter is 48ft
48/2=24ft is radius
height is 25ft
so volume=25pi24^2 or 14400pi cubic feet
max of 9ft
if we want 9ft height
find r
hmm
14400pi=9pir^2
divide both sides by 9pi
1600=r^2
sqrt both sides
40=r
2r=d
2(40)=80=d
the new diameter is 80ft
Hey the answer is 2713 cm
David can read 50 pages in 50 minutes.
(50 pages)/(50 minutes) = 1 page/minute
Since David reads 1 page per minute,
in 80 minutes David can read 80 pages.
