57/100 is the answer for your problem
Answer:
Two students will take 24 minutes to wash the car.
Step-by-step explanation:
In this case we can apply a rule of three to find out the time that will take for the students to wash the car. This has to be done such as:
3 students -> 16 minutes
2 students -> x minutes
3/2 = 16/x
But in this cases the problem states that this variables are inversely proportionate, which means that if there's less students washing the car they will take more time to finish the job. So we need to invert one of the fractions before computing the result.
3/2 = x/16
2*x = 3*16
x = 48/2 = 24 minutes.
Two students will take 24 minutes to wash the car.
Answer:
sorry i didnt really understand
Answer:
(a)
(b)
The distance traveled in 30 seconds is 45 miles
(c)
It takes 85 seconds to go 12.75 miles
Step-by-step explanation:
we are given
An airplane is flying from New York City to Los Angeles
d is the distance traveled in miles
t is time in second
we have equation as
(a)
we have to find speed
we can see that our distance equation is in linear form
For finding speed, we can compare our equation with equation of line
and slope of the line will be speed
because slope is the rate of change
where m is slope
so, we can compare
and we get
so,
(b)
we can plug t=30 and find d
miles
so, The distance traveled in 30 seconds is 45 miles
(c)
we can set d=12.75 and solve for t
So,
It takes 85 seconds to go 12.75 miles
Straight line means 180 degrees. SO, 56+y+51=180
107+y=180
y=73
Next, a triangle has 180 degrees, so 73+72+x=180.
X is 35.
