1) A speed walker covered 4 1/2 mi in 3/4 hour. How far will he walk with the same pace in 2 hours? 3 hours? 3.5 hours?
Savatey [412]

You can solve this with proportion

1)    For 2h

9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles

For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get

x/4=9/2 => x=(9/2)*4=18 miles

2)  2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>

x= (320*7)/2 = 160 * 7 = 1120 acres

Good luck!!!

How should this model be completed to represent 642/11 ??<br><br> Enter the answer in the box.
Rashid [163]

Model be completed to represent 642/11 is 29.1818181818

\frac{642}{11} = 58.3636363636

58.3636363636 = 583.636363636 to the nearest tenth

58.3636363636 = 58.36 to the nearest hundredth

58.3636363636 = 58.364 to the nearest thousandth

= 0 to the nearest tenth

= 0 to the nearest hundredth

= 0 to the nearest thousandth

Other Divisions Math homework are

642 divide by half plus 20

(\frac{642}{2}) + 20 = 341

642 divide by half plus 40

(\frac{642}{2}) + 40 = 361

\frac{642}{11} divided by 2

(\frac{642}{11}) ÷ 2 = 29.1818181818

Division is  one among  the four basic operations of arithmetic, the  ways in which  numbers are combined to make new numbers.  the opposite  operations are addition, subtraction, and multiplication.

At an elementary level the division of two natural numbers is, among other possible interpretations,  the method  of calculating the number of times one number is contained within another.7  This number of times  needn't  be an integer.  for instance , if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture).

The division with remainder or Euclidean division of two natural numbers provides an integer quotient, which  is that the  number of times the second number is completely contained in the first number, and a remainder, which  is that the  part of the first number that remains, when  within the  course of computing the quotient, no further full chunk of  the dimensions  of the second number can be allocated.  for instance , if 21 apples are divided between 4 people, everyone receives 5 apples again, and 1 apple remains.

For division to always yield one number  instead of  a quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers.

​ What are the zeros of the function?​ f(x)=x2+17x+72
Semmy [17]
In order to find zeroes of a function, we will probably want to use our quadratic formula.

-b±√b^2-4(a)(c)/2a 

If we know our values, we can plug it in. 

Our values:

A=1 (Since there is no number in front of x, it is an assumed 1)
B=17
C=72

Now, We can plug it into our formula.

BE SURE TO PUT PARENTHESIS AROUND ALL TERMS!

-(17)±√(17)^2-4(1)(72)/2(1)

Now we can type it into a calculator! 

When we plug it into the formula. It gives us two real solutions (or zeroes) which are represented as:

-8 & -9.
