Answer: About 1.34%.

Step-by-step explanation:

Given : About 50% of the population of Alaska lives within a 50-miles radius of Anchorage.

To find the area of the section within 50 miles , we need to find the area of the circle with radius =  50 miles.

Area of circle = \pi r^2

Then,

Area of the section within 50 miles= (3.14) (50)^2=7850\text{ miles}^2

Also, the area of Alaska is 586,412 miles.

Now, the percent of the total land area is within 50 miles of Anchorage :_

\dfrac{7850}{586412}\times100=1.3386492773\approx1.34\%

Hence, the percent of the total land area is within 50 miles of Anchorage= 1.34%

Which sets of ratios are a proportion? (Choose all that apply) *
vladimir1956 [14]

Answer:

<h2>Sets of Ratios that are Proportion</h2>

3/11 and 17/6

<h3>12/7 and 36/21</h3>

60/55 and 7/25

7/6 and 52/48

<h3>4/10 and 8/20</h3>

<h3>Solution:</h3>

> 12/7 and 36/21

\frac{12}{7}  =  \frac{36}{21}  \\ 12(21) = 36(7) \\ 252 = 252

> 4/10 and 8/20

\frac{4}{10}  =  \frac{8}{20}  \\ 4(20)  = 8(10) \\ 80 = 80

If a rectangle's length is y−2 and the width is 3y+2 write an expression for the perimeter and an expression for the area.
aalyn [17]

Answer:

Area = 3y^2 - 4y - 4 units square.

Perimeter = 8y units.

Step-by-step explanation:

Area of a rectangle = length * width.

Perimeter of a rectangle = 2*(length + width).

It is given that length = y−2 units and width = 3y+2 units. To find the area and the area of the rectangle in terms of y, simply put the length and the width in the above area and perimeter equations.

Area = length * width = (y-2)*(3y+2).

Expanding the expression gives:

Area = 3y^2 + 2y - 6y - 4 = (3y^2 -4y - 4) units square.

Similarly,

Perimeter = 2*(length + width) = 2*(y-2 + 3y+2) = 2*4y = 8y units.

Therefore, the expression for the area and the perimeter of the given rectangle is (3y^2 - 4y - 4) units square and (8y) units respectively!!!
