In regular polygons, if the number of sides, n, is odd, the lines of symmetry will pass through a vertex and the half of the opposite side.

This is equivalent to say that a perpendicular bisector of a side of the regular polygon bisects the angle of the opposite vertex to the side, and divide the polygon into two symmetrical parts.

Find the sticker price and dealer's cost for the Tarop Series car. The base price given is $24,990.00. The options for the Tarop

podryga [215]

Alright, lets get started.

The base price is given : $ 24990

The dealer pays 76% of the base price means

he pays for base price : $24990 * \frac{76}{100}$

he pays for base price : $ 18992.4

For options, total : $868 + 452 + 1260 = 2580$

He pays 88% for options, means

he pays for options : $2580 * \frac{88}{100}$

he pays for options : $ 2270.4

So, total dealer pays : $18992.4 + 2270.4 +$ destination charges

So, total dealer pays : $18992.4 + 2270.4 + 630 =$ $ 21892.8

Hence dealer's cost : $ 21892.8

Price of sticker will be : $24990 + 868 + 452 + 1260 + 630$

Price of sticker will be : $ 28200

dealer's cost : $ 21892.8

Hope it will help :)

Answer:

A diameter basically means width of a circle. A radius is half the width. A chord means a line that goes from one edge of a circle to the other. A chord does not have to be width but is can be. Usually shorter than the width though

Tcecarenko [31]

F = k x
15 = k *10
k = 1.5

check:
24 = 1.5 x
x = 16 sureenough

so 1.5 oz/inch
= 1/1.5 inches/oz = 2/3 = 0.6666.... in/oz
