Answer:

the answer is 1.453

Step-by-step explanation:

i am not sure about the answer but here are my steps. first he says in the 1990s  there was a deforestation rate of about 0.48%per year. and 1 is the rate of land that is shrinking. this means that if Brazil had a forest of area x then

x(0.48%)=1 therefore x=2.083

lets use that in this equation

the area left (the final answer) 2.083(0.48)^35= 1.453

(i asked about the unit its measured with because if it is measured by thousands of squared meters or kilometers just big unit measured to be exact my answer would be correct)

A rectangular piece of land has an area of 3/4 square mile. The land is 21/2 mile. What is its width
OleMash [197]

Answer:

The width of the rectangle is  \frac{1}{14} miles

Step-by-step explanation:

Given as for rectangle

The area of rectangle = A = \frac{3}{4} mile²

The Length of rectangle = L = \frac{21}{2} mile

Let The width of rectangle = W miles

Now, From area of rectangle

I.e Area of Rectangle = Length × Width

Or , A = \frac{21}{2} mile  × W mile

Or, \frac{3}{4} mile² = \frac{21}{2} mile  × W mile

or, W = \frac{\frac{3}{4}}{\frac{21}{2}} mile

or, W = \frac{3\times 2}{4\times 21}

∴  W = \frac{1}{14} miles

Hence The width of the rectangle is  \frac{1}{14} miles  Answer

Brent created a mural, 4/5 of which he painted in shades of blue. Three eighths of the blue area is sky blue. What portion of th
Snezhnost [94]

Answer: \frac{3}{10} of the mural is sky blue.


Step-by-step explanation:

Let x be the full portion of mural.

Since, \frac{4}{5} of mural is painted in shades of blue.

Therefore, the blue portion=\frac{4}{5}x

Also, Three eighths of the blue area is sky blue.

Therefore, the portion of the mural is sky blue=\frac{3}{8}\times\frac{4}{5}x

The portion of the mural is sky blue=\frac{12}{40}x

Simplify, by dividing numerator and denominator by 4, we get

The portion of the mural is sky blue=\frac{3}{10}x
