Answer: 239,306 total registered doctors

Step-by-step explanation:

1. Form the ratio of amount of female doctors(41,400) to total amount of doctors(x) and compare it to percent of female doctors in the field(17.3) to total percent of doctors(100).

[tex]\frac{41400}{x}=\frac{17.3}{100}[/tex]

2. Cross Multiply the amount of female doctors(41,400) to the total percent of doctors(100) so that it stays equal to the percent of female doctors(17.3) to the amount of doctors(x).

[tex]41400*100 = 17.3x[/tex]

3. Simplify

        [tex]\frac{414*10^{4} }{17.3} = \frac{17.3x}{17.3}[/tex]

The answer is 12 cubic feet

Answer:

Step-by-step explanation:

      Atsu  :  Sabu

         3     :     7

         x     :    x + 20

x is equal to the number of cedis

cross multiply the ratio above

3(x+20) = 7x

3x + (20×3) = 7x

3x + 60 = 7x

3x - 3x + 60 = 7x - 3x                  (put - 3x on both sides of the equation)

60 = 4x

60/4 = 4x/4                                (divide both sides by 4)

15 = x

Answer:

4 inches.

Step-by-step explanation:

Since the shape is a square, each side length will be the same. This mean that you must find the square root of 36 to find the length of each side of the new square.

√36=6

Each side of the new square is 6. It says it was lengthened by 2 inches. Subtract 2 from 6.

6-2=4

Each side of the original square is 4 inches.

Your question is incomplete, probably the missing part is:

Answer:

69

Step-by-step explanation:

45*69+1895=5000

Answer:

h = 69

Step-by-step explanation:

45h + 1895 = 5000 ( subtract 1895 from both sides )

45h = 3105 ( divide both sides by 45 )

h = 69

You will $0.29, if you will purchase 2 small bags of flour instead of 1 big bag.

For the given question;

The total cost of one big bag that is 10-lb bag of flour = $3.69.

Now, the cost of one small bag that is 5-lb = $1.55.

Thus, the cost for two small bag that is 5-lb = $3.10.

The difference in the cost = big bag cost - 2 small bag costs.

The difference in the cost = $3.69 - $3.10

The difference in the cost = $0.29.

Thus, you will save $0.29 for the purchase of 2 small bags of floor instead of one big bag.

Answer:

predict the impact of removing snakes from this food web

Answer:

189

Step-by-step explanation:

The difference between consecutive terms of an arithmetic sequence, known as the common difference  is given by
d = a(k) - a(k-1) where k = 1,2,3 ....n

We have the 5th term as a(5) = 9

The 6th term is 9 + d

The 7th term is 9 + 2d

The 8th term is 9 + 3d

Each successive term adds a d to the previous term

We have 8th term = 27

So 9 + 3d = 27
3d = 27 - 9   (subtract 9 from both sides)

3d = 18  

Divide above by 3 on both sides to get

d = 18/3 = 6  

So the common difference is 6

Let's figure out how to calculate the 31st term

We can see that the 5th term can be expressed as
9 + 0d = 9 + 0.6 = 9

The sixth term is
9 + 1d = 9 + 1(6) = 9 + 6 = 15

The seventh term is 9 + 2d = 9 + 12 = 21 and so on

Therefore the general equation for the nth term, given the 5th term

is
a(n) = a(5) + (n - 5)(6) 9 + 6(n - 5)

So the 31st term is

a(31) = 9 + 6(31-1)  9 + 6 x  30 = 9 + 180 = 189

Answer: 31st term is 189

The value of x from the given diagram is 64 degrees

A line is defined as the shortest distance between two points. From the given diagram, we have that the line AB bisects FAB, hence;

<FAB = <CAB = 58 degrees

Also since the sum of angles on a straight line is 180 degrees, hence;

58 + 58 + x = 180

116 + x = 180

x = 180 - 116

x = 64 degrees

Hence the value of x from the given diagram is 64 degrees

-3 1/3³ = 1/27

-2 1/3² = 1/9
