One idea is:
Paul wants to buy an iphone X. He has savings of $100 to start with. Local McDonalds pays $7 per hour (after tax) to students on summer break for helping out at the counter. The iphone costs $1000. At least how many hours does Paul need to work at McDonalds to be able to afford the iphone.
So, that matches ax+b>c in that
a is the hourly earning
b is the initial savings
c is the price of the iphone
9 and 1/12 inches of pipe remain because
30 and 3/4 = 30 and 9/12
4 and 1/3 = 4 and 4/12
4 and 4/12 x 5 = 20 and 20/12
which can be simplified to 21 and 8/12
30 and 9/12 - 21 and 8/12 = 9 and 1/12.
Answer:
its D 103°
Step-by-step explanation:
Sum of a pentagon=540
117+100+115+105+x=540
437+x=540
x=540-437
x=103°
Set up a proportion:
2 x
-- = --
5 10.5
Then just solve for x
50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
