Answer:

the correct option is c) 722,357,000

Step-by-step explanation:

A rounded number is about the same value as the number we have, but it is less exact.

All the numbers to the right of the place which are rounding to become zeros.

example -

54 rounded to the nearest ten is 50

7,909 rounded to the nearest hundred is 7,900

Given number is 722,356,964

since, the last three digit of 722,356,964 is round to tenth is 1000

and when it is combine with 722,356,964 this will become 722,357,000

Hence, the correct option is c) 722,357,000

A vat contains 18 gallons of liquid when a drain pipe opens and the liquid begins to leave the vat at a rate of 4 gallons per ho

SashulF [63]

Answer:

$y=-4x+18$

Step-by-step explanation:

Let x be the number of hours.

We have been given that a vat contains 18 gallons of liquid when a drain pipe opens and the liquid begins to leave the vat at a rate of 4 gallons per hour.

To graph the amount of liquid first of all we will find the equation of line for our given situation.

Since we know that equation of a line in slope-intercept form is: $y=mx+b$ , where, m = slope and b = y-intercept or initial value.

As liquid is leaving the vat at a rate of 4 gallons per hour, this means that amount of liquid in vat in decreasing 4 gallons per hour. As slope is also known as rate of change, so slope of our given line will be -4. A negative slope means that with each increase in x our y will decrease by 4.

As initially there were 18 gallons of liquid in vat, so our y-intercept will be 18.

Upon substituting our given values in slope-intercept form of equation we will get,

$y=-4x+18$

Let us find x-intercept by substituting y=0 in our equation.

$0=-4x+18$
