The Wallow Fire of 2011 burned 538,000 acres in eastern Arizona. a. If one square mile is 640 acres, how many square miles did the fire burn? (You must use unit fractions. Round to 1 decimal place and be sure to include units.) b. The city of Tempe is about 50 square miles in size. How many Tempes would this fire have burned? (You must use unit fractions. Round to 1 decimal place.)

The square miles and Tempe burnt by fire is an illustration of proportions.

The given parameters are:

(a) The number of square miles, the fire burns

1 square mile = 640 acres

So, the number of miles is calculated as:

So, we have:

Hence, the number of square miles is 840.6

(b) The number of temple, the fire burns

1 Tempe = 50 square miles

So, the number of Tempe is calculated as:

So, we have:

Hence, the number of temples is 16.8

a) The fire burnt 840.6 square miles

b) The fire burnt 16.8 tempe

Step-by-step explanation:

1 square mile = 640 acres

a) to find how many square miles did the fire burn:

Total area the fire burn = 538000 acres

1 square miles = 640 acres

Concert the acres into square miles

538000/ 640 = 840.6 square miles

The fire burnt 840.6 square miles

b) 50 square miles= 1 temperatures

The no. Of tempe the fire burn = 840.6/50

= 16.8 tempe

The fire burnt 16.8 tempe

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

your answer   is c
