Lusia ran 3 2/3 kilometers in 1/3 of an hour. If speed is distance over time, calculate lusia's speed.

Answers

Answer 1
Answer: In the question, they give you the formula for speed...

speed = distance / time

They also give you the distance and the time, so all we have to do is stick them into the equation...

speed =  3 2/3 Km / 1/3 hour
speed = 3 2/3 / 1/3

To divide the fractions, first we need to convert 3 2/3 into an improper fraction

3 2/3 = 11/3

now we multiply 11/3 x the reciprocal of the divisor 1/3.  The reciprocal just means flip the numerator and denominator

speed = 11/3 x 3/1
speed = 33/3
speed = 11 Km/hour

a bucket holds 243.5 oz of water. The bucket loses 0.3 oz of water per second.In how many seconds will the bucket be 40% full

Answers

ok so 
t=time in seconds
therefor the smount lost for t seconds is 0.3 ties t or 0.3t
loss so it is ngative
-0.3t
the question is
243.5-0.3t=40% of 243.5
first, find 40% of 243.5
percent means partst out of 100 so 
40%=40/100=0.4
'of' means multiply
40% of 243.5=0.4 ties 243.5=97.4
now the question is
243.5-0.3t=97.4
for ease, multiply whole equation by 10 to make no decimals
2435-3t=974
subtract 2435 from b oth sides
-3t=-1461
divide both sides by -3
t=487

answer is 487 seconds (aka 8 mins, 7 secons)

answer is 487 sseconds

Answer:

487 seconds

Is the quotient of 2 nonzero integers always an integer explain

Answers

integers are whole numbers, they can be positive or negative....they are not decimals or fractions.

quotient means divide...so lets pick 2 non zero integers....2 and 3....now divide them.
2/3 = 0.66....so ur answer is FALSE..because we took 2 non zero integers and divided them, but we didn't get an integer as an answer.

Sometimes it is true...but not all the time.
2/4 = 2...here it is true
2/3 = 0.666 ...here, it is not

Is 36 yards 2 feet greater than less then or equal to 114 feet 2 inches

Answers

It would be less then because, first we need to convert yards into feet which the formula for doing that is 3 feet per yard so if you have 36 yards you would take 36*3=108 then you would add 2 feet because there are 2 extra feet to add on to the end of this question. Like so 108+2=110 then we see which one is bigger 114<110 does not work out and 114=110 is no true but 114>110 is correct and works out to be true therefore your answer is 114 and 2 inches is bigger then  26 yards and 2 feet.

Enjoy!=)
less than because you make 144 feet into yards and you get 48 and then turn 2 feet from the first distance into inches and your inequality would be this
36yards24inches<48yards2inches
