Answer:
Step-by-step explanation:
40/100 musicians .75*40= 30
30 is to 100
as 38 is to x
30 38
---- = ------ Cross multiply
100 x
30x=3800
divide by three to get
126 and 2/3
you can't split people, so it would be closer to about 127 students.
The interest is computed from
... I = Prt
where P is the principal amount ($569), r is the rate (0.045) and t is the time in years (250/360).
... I = $569×0.045×250/360 ≈ $17.78
Please note that time is not rounded. Rather, the exact value (25/36) is used in the calculation. The only rounding of any number is done at the end, where the amount is rounded to the nearest cent. (Your text authors should know this.)
_____
If you follow the problem instructions (which Valerie's lender will <em>not</em> do), the interest is calculated as ...
... t = 250/360 = 0.6944444... ≈ 0.69 . . . . years
... I = $569×0.045×0.69 ≈ $17.67
_____
Note the rounding of intermediate numbers (time) introduces an error of about $0.11 in the answer.
The answer is 6. 36 is a squared number
Answer: 22 minutes
Step-by-step explanation: 500-170 means that he drained 330 gallons of water so 330 divided by 15 gallons a minute so you get 22 so it takes 22 minutes to have 170 gallons left in the pool
So to start you half to have an equation. $3.25x is going to be on part of your equation for each pound. $39.00 is going to be your total amount of all your meat. So your equation is going to be 40=3.25x+39 then you would solve the equation from there
