A farm had 480 acres more wheat than corn. Let use "W" to represent the Wheat and let use "C" to represent the corn. Hence, we have below:
W=C+480

The farmers collected 80% of the wheat and 25% of the corn and the area of the wheat is 300 acres less than the area of the corn:
W-0.8W=C-0.25C+300
0.2W=0.75C+300
We have two equations, two unknowns:
0.2(C+480)=0.75C+300
0.2C+96=0.75C+300
0.55C=294
C=534.55

Answer:

wheat acres is 1200.Corn acres is 720.

Step-by-step explanation:

A farm had 480 acres more wheat than corn.W represent wheat.C represents corn.So the equation for this part is:W=C+480.

After the farmers collected 80% of the wheat and 25% of the corn, the area of the wheat was 300 acres less than the area of the corn. So the equation is:W-w-0.8W+300=C-0.25C.which simplfies to:

0.2W+300=0.75C

we have 2 eqations with unknown variables.

W=C+480

0.2W+300=0.75C

we will use the substitution method by plugging in the first equation into the second equation.

0.2(C+480)+300=0.75C.

now solve for C.

0.2C+96+300=0.75C.

396=0.55C

C=720.

solve for W:

W=C+480

W=720+480

W=1200

Elza [17]

Answer:

The average selling price of each trailer was nearly $922

Step-by-step explanation:

University trailer sales company sold 356 utility trailers during a recent year.

If the gross annual sales for the company was $328,132.

For the average selling price of each trailer, we will divide <em>the gross annual sales </em>by <em>utility </em><em>trailers.</em>

= 328132 ÷ 356

= 921.7 ≈ 922

Thus, The average selling price of each trailer was nearly $922

What are the steps to construct parallel lines using a compass and straightedge.
kari74 [83]

The first thing you do is draw a straight line. It can be any length. Then draw a point above the line. Place the stylus of the compass on the point, and swing the compass down to make two marks on the line. Then, draw marks below the line, by placing the stylus on the points of intersection. Draw a line from where these two meet to the original point.Mark two points on the 2nd line by placing the compass stylus on the original dot, and swinging it down and up. Then, swing the compass from both of these new points of intersection , on either side of the line, to form 2 new points.Connect these 3 points, and now you have 2 parallel lines! The original line and the most recently made are parallel with each other. Hope this helps!

The graphs below have the same shape. what is the equation o the red graph?
maw [93]

So the equation of the red graph is already given to us: f(x) = x^2. I assume you meant the blue graph?

We can use the vertex form: y = a(x - h)^2+ k, where (h,k) is the vertex. (We can ignore a because a is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).

The vertex for g(x) is at (-4, -2) on the coordinate plane. (4 left, 2 down)

Plug into the vertex form:

y = (x - (-4))^2 -2

The double negative becomes a positive, and then you're done:

y = (x + 4)^2-2
