The spoilage rate on a shipment of wheat is expected to be 20%. It was purchased at a cost of $5.35 per bushel. What should the

kompoz [17]

Answer:

$7.09

Step-by-step explanation:

Let wheat shipment be x bushels

Per bushel cost = 5.35

So x bushels cost = 5.35x

Achieving markup of 6% means 1.06 * 5.35x =5.671x

20% spoiled means 80% of x stays, so 0.8x will need to be sold at 5.671x

Selling price should be 5.671x/0.8x = $7.09

So that's 7 dollars and 9 cents

The Eiffel Tower is 324 m tall. If a tourist is looking at it from 100 m away from the base,

romanna [79]

Answer:

80,94º

Step-by-step explanation:

What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).

So I calculated the tangent of the angle of the tourist.

The formula is tan=Oposite side/adjacent

$tan=\frac{opposite side}{adjacent}$

$tan=\frac{324}{100} =3.24$

And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).

I hope it helped.
