Molly is raising cows. She has a pasture for them that is 0.65 square miles in area. One dimension of the pasture is 0.4 miles l
dem82 [27]

Answer:

The other dimension of the pasture (width) is 1.625\ mi

Step-by-step explanation:

In this problem I assume that the pasture has the shape of a rectangle.

Let

x -----> the length of the pasture

y -----> the width of the pasture

we know that

The area of the pasture (rectangle) is equal to

A=xy

we have

A=0.65\ mi^{2}

x=0.4\ mi

substitute and solve for y

0.65=0.4y

y=0.65/0.4

y=1.625\ mi

Can someone show me how to do it and the answer
Virty [35]

Answer:

B

Step-by-step explanation:

The equation of a circle is

(x-h)^2 + (y-k)^2 = r^2

h= 9, k = -7

r = 2, so r^2 = 4.

We now know that the equation must equal 4, so we can rule out answers A and C.

Plug in the values for h and k to get

(x-9)^2 + (y+7)^2 = 4

Choice B is correct!

The equation r = 6t gives the number of albums released, r, by a record label over time in years, t. If you graph this relations
GalinKa [24]
R = 6t.....subbing in (8,48).....t = 8 and r = 48
48 = 6(8)
48 = 48 (correct)

r = 6t...subbing in (13,78)...t = 13 and r = 78
78 = 6(13)
78 = 78 (correct)

so u have 2 sets of points on this line and they are (8,48) and (13,78)
