Farmer Brown planted corn and wheat on his 430 acres of land. The cost of planting and harvesting corn (which includes seed, pla

nting, fertilizer, machinery, labor, and other costs) is $280 per acre. The cost of planting and harvesting is wheat is $125 per acre. If Farmer Brown’s total cost was $95,600, how many acres of corn than wheat did the farmer plant?

Answer:

The farmer planted 270 acres of corn and 160 acres of wheat.

Step-by-step explanation:

Let the acres of corn be = x

Let the acres of wheat be = y

Total acres of land = 430

So, we have x+y=430 or x=430-y    .....(1)

The cost of planting and harvesting corn is $280 per acre. The cost of planting and harvesting wheat is $125 per acre. The farmer spent $95600 on plantation.

We get another equation as:

280x+125y=95600      .....(2)

Substituting the value of x from (1)

280(430-y)+125y=95600

=> 120400-280y+125y=95600

=> -280y+125y=95600-120400

=> -155y=-24800

y = 160

And x = 430-160

x = 270

So, the farmer planted 270 acres of corn and 160 acres of wheat.

Answer:

1296mm^2

Step-by-step explanation:

Surface Area of the Rectangular Prism to the left on top of the box:

Area of square = lw, 9mm * 9mm = 81mm, then multiply by 2 because 2 of the squares are a part of the surface, giving <u>162mm^2</u>

Area of a rectangle =lw, 9mm * 9mm = 81mm, then multiply by 2 again, because 2 rectangles are a part of the surface, giving <u>162mm^2</u>

So, the total surface area of the rectangular prism to the left on top, is 324mm^2

Surface Area of the Triangular Prism:

Area of a triangle: 1/2bh, and our base length would be 12, because we have to subtract 9 from 21 since the base length of the triangle isn't stated. Anyways, A = 1/2bh, so A = 1/2(12)(9) = 54mm^2, but multiply by two, so we get <u>108mm^2</u>.

Area of the rectangle: lw, so 15mm * 9mm = <u>135mm^2</u>

So, the total surface area of the triangular prism is 243mm^2

Surface Area of the Rectangular Prism at the bottom:

Area of the long rectangles in front = lw, 21mm * 9mm = 189mm^2, multiply by 2, <u>378mm^2</u>

Area of the rectangles to the side = lw, 9mm * 9mm = 81mm^2, multiply by 2, <u>162mm^2 </u>

Area of the rectangle at the very bottom = lw, 21mm * 9mm = <u>189mm^2</u>

So, the total surface area of the rectangular prism at the bottom is 729mm^2

Add all the total surface areas of each shape to get the total surface area of the figure:

324mm^2 + 243mm^2 + 729mm^2 = 1296mm^2

The surface area of the figure above is 1296mm^2
