ratio of 9:2

 means for every 9 cows there are 2 horses

72/9 = 8

 8 x 2 = 16

 there are 16 horses

Answer:  The required number of horses at the farm is 16.

Step-by-step explanation:  Given that at a farm, the ratio of cows to horses was 9:2 and there were 72 cows at the farm.

We are to find the number of horses at the farm.

Let the number of cows and horses at the farm be 9x and 2x respectively.

Then, according to the given information, we have

\textup{number of cows}=72\\\\\Rightarrow 9x=72\\\\\Rightarrow x=\dfrac{72}{9}\\\\\Rightarrow x=8.

Therefore, the number of horses at the farm will be

2x=2\times8=16.

Thus, the required number of horses at the farm is 16.

Answer: The equation is (x+4)^2 + (y-4)^2 = 9\\\\

Center = (-4,4)

Radius = 3

===========================================================

Explanation:

This graph shows the circle's center is at (-4, 4)

Recall in general, the center is (h,k)

So we see that (h,k) = (-4,4). More specifically: h = -4 and k = 4.

The radius of this circle is r = 3 as this is the distance from the center to any point on the edge. For example, go from (-4,4) to (-1,4).

With the h, k and r values in mind, we then say the following:

(x-h)^2 + (y-k)^2 = r^2\\\\(x-(-4))^2 + (y-4)^2 = 3^2\\\\(x+4)^2 + (y-4)^2 = 9\\\\

which represents the equation of this circle.

Whats the perimeter of a semicircle of 6cm​
pashok25 [27]

Answer:

P = 15.42 cm

Step-by-step explanation:

Perimeter of circle = (πD/2)+D

Where D = 6 cm

P =( (3.14)(6)/2) + 6

P = (3.14)(3)+6

P = 9.4 + 6

P = 15.4 cm

Form a sequence that has two arithmetic means between -13 and 89. a. -13, 33, 43, 89 c. -13, 21, 55, 89 b. -18, -36, -72, -144 d

<span>Form a sequence that has two arithmetic means between -13 and 89. a. -13, 33, 43, 89 c. -13, 21, 55, 89 b. -18, -36, -72, -144 d. -18, -81, -144

Solution:

Since  it has to be between -13 and 89, letter d and b are not anymore considered to be the answer.

for a:
33-(-13)=46=d
43-33=10=d the value for this d is different from the two sequence,
89-43=46=d
they have different value for d, thus this is not the answer!

for c:
21-(-13)=34=d
55-21=34=d
89-55=34=d

they have the same value for d, thus the correct answer is </span><span> c. -13, 21, 55, 89</span>
