3,100

You add up what she is getting and than subtract how much she needs with what she has so far. And that’s the answer. So 2000+ 1500= 3500 than 6,600-3500

A novel is 11/16 inch thick. If there are two shelves, each 99 inches wide, how many novels will be able to fit on the two shelv

34kurt

First let's just combine the shelves to make it easier. 99 + 99 = 198.

We can simply divide 198 by 11/16 to get the answer. First let's convert 11/16 to a decimal.

11 divided by 16 is 0.6875

So 198 divided by 0.6875 is 288.

288 novels can fit on both the shelves.

An exterior angle of a regular convex polygon is 40°. What is the number of sides of the polygon?

seraphim [82]

Answer:

option B

Step-by-step explanation:

Sum of interior angles of a polygon with n sides:

$= (n - 2 )\times 180$

$Therefore, Each \ interior \ angle = (\frac{n - 2}{n} )\times 180$

$Sum \ of \ one \ of \ the \ interior \ angle \ with \ its \ exterior \ angle \ is \ 180^\circ$

$[ \ because \ straight \ line \ angle = 180^\circ \ ]$

That is ,

$Exterior \ angle + Interior \ angle = 180^\circ\\\\40^ \circ + (\frac{n-2}{n}) \times 180 = 180^\circ\\\\40 n + 180n - 360 = 180n\\\\40n = 180n - 180n + 360 \\\\40n = 360 \\\\n = 9$
