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%

Mary month earnings can be given as R(x)=13x+155 where x equals the number of hours worked josies monthly are given as Q(x)=9x+3
tatuchka [14]

Answer:

45hours

Step-by-step explanation:

Given

Mary month earnings to be R(x)=13x+155

Josies monthly earning is given as Q(x)=9x+335

If Josie and Mary work to earn the same salary, then R(x) = Q(x)

13x+155 = 9x+335

subtract 155 from both sides

13x+155-155 = 9x+335-155

13x = 9x+180

subtract 9x from both sides

13x-9x = 9x+180-9x

4x = 180

x = 180/4

x = 45

Since  x equals the number of hours worked by Josie and Mary, this means that Josie and Mary must work for 45hours to earn the same salary

A quantity a varies directly as a quantity b, if, when b changes, a changes in the same ratio. What happens to the quantity a if
drek231 [11]
This means that if b doubles, then a will become half as large. For the inverse of the ratio 2 to 1 ("doubles") is the ratio 1 to 2 ("half"). The terms are exchanged; the inverse of the ratio a : b is the ratio b : a. When a varies inversely as b, we say that a is inversely proportional to b.
