The perimeter is 18+18+20+20=76. 18 square root 2 /2= 12.727. Hypotenuse or triangle is 18 + 12.727+12.727=43.455. 76.18+43.455=119.635. The area is 18x20=360. (12.727x12.727)/2= 161.9765. 161.9765+360= 521.9765.
For the hypotenuse since it is a 45,45,90 triangle the two side lengths are are same so it is x square root 2 divide by 2. Hope that helps!!

Enter the number that belongs in the green box.

Answers

Answer:

The number 80 should go in the green box

Step-by-step explanation:

To solve this equation you will need to use the pythagorean theorem. Which is a^2 + b^2 = c^2. Also you will need to know where the legs and hypotenuse of the triangle are. The hypotenuse is the longest side of the triangle. So that would be the side marked 12. Then the other two sides are legs.

To solve for x you need to input your known numbers into the pythagorean theorem and solve. To know where the numbers go, a and b of the equation are the legs of the triangle and c is the hypotenuse. I solved the equation for you in the photo I inserted.

Hope that helped you!

Answers

Answer:

x=1 y=1

Step-by-step explanation:

You want to chose either x or y to cancel out of both equations. I chose y, so I multiplied the entire equation of 3x-y=2 by 2 to get 6x-2y=4

6x-2y=4

x+2y=3

The -2y and 2y cancel each other out, the 6x and x can be added, and the 4 and 3 can be added.

7x=7

x=1

Now that we know x=1, plug in x to one of the original equation.

LG Company is considering the purchase of a new machine. Its invoice price is $123,000, freight charges are estimated to be $3,000, and installation costs are expected to be $5,000. Salvage value of the new machine is expected to be zero after a useful life of 4 years. Existing equipment could be retained and used for an additional 4 years if the new machine is not purchased. At that time, the salvage value of the equipment would be zero. If the new machine is purchased now, the existing machine would be sold for $5,000. LGs accountant, Ethan Ng, has accumulated the following data regarding annual sales and expenses with and without the new machine.Without the new machine, LG can sell 10,000 units of product annually at a per unit selling price of $100. If the new unit is purchased, the number of units produced and sold would increase by 25%, and the selling price would remain the same.The new machine is faster than the old machine, and it is more efficient in its usage of materials. With the old machine the gross profit rate will be 28.5% of sales, whereas the rate will be 30% of sales with the new machine. (Note: These gross profit rates do not include depreciation on the machines. For purposes of determining net income, treat depreciation expense as a separate line item.). The old machine breaks down three to four times a year. The staff had requested the management to buy a new machine as the old machine is challenging to operate.Annual selling expenses are $160,000 with the current equipment. Because the new equipment would produce a greater number of units to be sold, annual selling expenses are expected to increase by 10% if it is purchased.Annual administrative expenses are expected to be $100,000 with the old machine, and $112,000 with the new machine.The current book value of the existing machine is $40,000. LG uses straight-line depreciation.LGs management has a required rate of return of 15% on its investment and a cash payback period of no more than 3 years.Additional information:The company provides jobs to many local citizens where they are located. Having the new machine will reduce the hiring of new employees in the coming future.If there are any cost savings, the management would like to use the money for training and professional development of staff.The old machine is more environmentally compared to the new machine.Based on research, the inventory turnover will change from 3.45 to 3.47 with the new machineInstructions:Write a memo to the Chief Financial Officer and the President of the company detailing your explanation of your recommendations. Please note the President has no finance background.You recommendation should have the following but not limited to:(Ignore income tax effects.)Calculate the annual rate of return for the new machine. (Round to two decimals.)Compute the cash payback period for the new machine. (Round to two decimals.)Compute the net present value of the new machine.
