Find x and the measures of the indicated parts.

1 answer:

7 0

notice the arrows on DC and BE, that simply means DC || BE, and therefore the angles ∡D = ∡E and ∡C = ∡B, so the triangles are similar by AA.

check the picture below.

therefore,

BC = x + 4 = 6 + 4 = 10

AC = 10 + 2 = 12.

What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1? -3 - -

Shalnov [3]

Answer: 2/3x

Step-by-step explanation:

First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with

y = 3/2x - 1/2

Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x

A book store sells a textbook for $150. If the textbook is on sale with 12% off, and there is a sales tax of 8.25% added to the

Yuri [45]

The textbook is $150 originally, so to find the price of the textbook on sale, multiply the original price by 12% (0.12). Then subtract 12% of 150 from 150.

150 * 0.12 = 18

Subtract 18 from 150.

150 - 18 = 132

Multiply the price of the textbook on sale by the sales tax of 8.25% (0.0825). Then add the tax price onto the sale price of the textbook.

132 * 0.0825 = 10.89

Add 10.89 to 132.

132 + 10.89 = 142.89

The final price of the textbook is $142.89.
