The remaining number, using the concept of average, is
It is given that
Average of three numbers = V
One number = z
Another number = y
Average is the sum of observations divided by a number of observations.
Let us take the third number x
From the question
Therefore, the remaining number is

Step-by-step explanation:
First, to find the boundary we need to find the amount of money left, simply subtract the spent amount from the total:
60 - 45.95 = 14.05
Seeing as this is the amount, she can spend any amount up to and including 14.05, so we need an equal to or smaller than sign:
Let x be the value of the object:
Which is the inequality!
Answer:
the minimum speed, in feet per second, that the conveyor must move is 7.07143 ft/sec
Step-by-step explanation:
Let's assume time it takes to cool is 't' seconds
so, we are given
The castings cool at the rate of 0.3°F (degrees Fahrenheit) per second
so, total change in temperature will be
must not be allowed to cool more than 7°F before being heat treated
so, that temperature must be equal to 7
now, we can solve for t
sec
now, we are given length of casting is 55 yards
so, firstly we will change it into ft
1 yard =3 ft
so,
so, we have
total length =55 ft
now, we can use speed formula
we can plug values
so, speed is 7.07143 ft/sec
