A sign is being made from a rectangular board of wood that originally measures 36 inches by
lozanna [386]
<h3>Solution (a):</h3>
  • Area of rectangle = LB
  • => Area of rectangle = 18 x 36
  • => Area of rectangle = 648 in²
<h3></h3><h3>Solution (b):</h3>

<u>Since the two triangles are equal (as said in the question):</u>

  • => Area of triangles: 2(1/2 x 6 x 18)
  • => Area of triangles: 6 x 18
  • => Area of triangles: 108 in²
<h3 /><h3>Solution (c):</h3>

<u>Subtract the area of the triangles from the area of the rectangle.</u>

  • 648 - 108 = Area of trapezoid
  • => 540 in² = Area of trapezoid

Your boss hands you the monthly data that show the number of orders coming into and out of the warehouse. The data are in the ta
exis [7]

The number of orders in is equal to the number of orders out in month 4 (April). It appears the solution represents the time at which warehouse shipments caught up with order quantities.

_____

For this table to make any sense, we have to assume that the year started with 3 orders in January, and that one order was shipped in January. Then the number of orders was 1 or 2 each month after that, and the number of orders shipped per month was 2 each month after that. That is, the tables represent year-to-date totals of orders in and out.

<em>Alternate Interpretation</em>

If the numbers here are actual orders in and out in each of the listed months, it appears the warehouse is getting better at shipping orders. That is, they are increasing the shipment rate by 2 orders a month each month. They will eventually ship enough to cover the total number of orders in (total of 20 by April), but total shipments through April only amount to 16 orders.

Write the equation of line AB, in slope-intercept form, given the points A(0, 6) and B(-6, -12). In your final answer, include a
Mamont248 [21]
Since A is on the y-axis, 6 is the y-intercept.

m = Δy ÷ Δx
m = (0 + 6) ÷ (6 + 12)
m = 6 ÷ 18
m = \frac{1}{3}

y = \frac{1}{3}x + 6
