A car depreciated by 25% during the first year. If the car was purchased for 28,000 what is the car worth today? Show your work.

zaharov [31]3 years ago

Depreciation is a reduction in value of an asset. Therefore, a 25 percent depreciation would mean a reduction of ¼ on the initial worth of the car.

Reduction = 28,000 * (1/4) = 7,000

Car worth today = 28,000 – 7,000 = 21,000

If one of the angles of a triangle is 130 degree then the angle between the bisectors of the other two angles can be
Viefleur [7K]

Answer: D) 155

Step-by-step explanation:

let <A, <B,<C are three angles in a triangle.

sum of the three angles in a triangle is 180degree.

<A+<B+<C=180

130+<B+<C=180 since one angle is given

<B+<C =180-130

<B+<C=50

(<B+<C)/2=25----(1)after bisecting sum of the angles

required angle =180-25=155

d is correct answer

Give two different sequences of three transformations that would map PQR onto EFG given that PQR=EFG.
Gre4nikov [31]

9514 1404 393

Answer:

  1. Translate P to E; rotate ∆PQR about E until Q is coincident with F; reflect ∆PQR across EF
  2. Reflect ∆PQR across line PR; translate R to G; rotate ∆PQR about G until P is coincident with E

Step-by-step explanation:

The orientations of the triangles are opposite, so a reflection is involved. The various segments are not at right angles to each other, so a rotation other than some multiple of 90° is involved. A translation is needed in order to align the vertices on top of one another.

The rotation is more easily defined if one of the ∆PQR vertices is already on top of its corresponding ∆EFG vertex, so that translation should precede the rotation. The reflection can come anywhere in the sequence.

__

<em>Additional comment</em>

The mapping can be done in two transformations: translate a ∆PQR vertex to its corresponding ∆EFG point; reflect across the line that bisects the angle made at that vertex by corresponding sides.

Y’all help, I have no idea what sec is or how to find it
IRINA_888 [86]
Sec is the length of the hypotenuse divided by the length of the adjacent side.

Meaning divide 20/16

Meaning your secant or sec is 1.25 or 1 1/4

Explain a thought process you might use when trying to find the additive or multiplicative inverse of a number or expression. ..
gizmo_the_mogwai [7]
Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other. 


<span>......................................... IF A + B = 0 , they are the additive inverse of each other. 
</span>

<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>

<span>......................................... A.B = 1 , they are the multiplicative inverse of each other. 
</span>

<span>Example of: </span>

<span>Additive inverses :................ 5 + ( - 5 ) = 0 </span>

<span>Multiplicative inverses...........5 x 1/5 = 1 </span>
