Arrange the numbers in decreasing order of their values.
FinnZ [79.3K]

Answer:

The numbers in decreasing order of their values are:

\cfrac{19}{3}>\sqrt{37}>6.08171...>6.012

Step-by-step explanation:

Before actually comparing, we need to write all of those numbers in decimal form, that will be the only way to actually tell which one is bigger since you are already given numbers in decimal form.

Converting numbers in decimal form.

The first number we are given is \sqrt{37}, we know it is a bit higher than 6, since the square root of 36 is 6, so using a calculator we get

\sqrt{37}=6.0828

The second number is a fraction, in decimal form will be:

\cfrac{19}{3}= 6.3333

Writing the decreasing order.

Now that all numbers are in decimal form we can compare them and write them in decreasing order.

6.3333... > 6.0828...>6.08171...>6.012

Lastly we can write the decreasing order using the numbers on their original form.

\cfrac{19}{3}>\sqrt{37}>6.08171...>6.012

A new Youth Sports Center is being built in Hadleyville, The perimeter of the rectangular playing field is 430 yards. The length
cricket20 [7]

Answer:

Width = 44 yards

Length = 171 yards

Step-by-step explanation:

given data

length of the field = 5 yards

Perimeter of the rectangular field = 430 yards.

solution

we consider here length of the field = L

and width of the field = W

as we know length of the field 5yards less than quadruple the width

so here

L = 4W - 5       .....................................1

and  

Perimeter (P) will be here

P = 2(L + W)      ............................................2

put here equation 1 value

430 = 2(4W - 5 + W)  

solve it we get

W = 44

so here put value in eq 1 we het

L = 4W - 5          

L = 4(44) - 5

L = 171

so, length of the field is 171 yards
