Deborah bought a computer for 25% off the list price. If the list price is $2,428, how much did Deborah spend? A. $607 B. $1,821
Softa [21]

Answer:

Option A, \$607

Step-by-step explanation:

Given: Deborah bought a computer for 25\% off the list price.

The list price is \$2,428.

To find: The amount Deborah spent on the computer.

Solution: We have,

List price of the computer =\$2,428.

Deborah bought the computer for 25\% off the list price.

The amount Deborah spent on the computer =25\% \times 2,428

=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607.

So, Deborah spent \$607 on the computer.

Hence, option A is correct.

Kite WXYZ is graphed on a coordinate plane. What is the area of the kite?
Misha Larkins [42]

Answer:

14 square units

Step-by-step explanation:

There are several ways we can find the area.  Probably the easiest is to cut the kite in half vertically and find the area of each triangle.  The area of the kite will be double that.

The height of the kite is 7 units, and the width is 4 units.  So each triangle will have a base of 7 and height of 2.

A = 1/2 bh

A = 1/2 (7) (2)

A = 7

The area of the kite is double that, so:

2A = 14

Need help with these two questions
WITCHER [35]

Answer:


Step-by-step explanation:

Answer:(A)= (-x^11)/(y^7)

(B)= (1/12xy^5)


Step-by-step explanation:

(A) (3x^3y^-2)(-2x^-3y^2)^-5/(6x^7y^-5)

[(3x^3y^-2)(-2x^15y^-10)]/(6x^7y^-5)

(6x^18y^5)/(-6x^7y^12)

(-6x^11)/(6y^7)

(-x^11)/(y^7)

(B) [(12x^-3y^5)/(x^-4)]^-1

(1/12xy^5)

Write the equation of the parabola in vertex form. <br> vertex (2,1) point (3,-3)
Mariana [72]

first off let's notice that hmmm the vertex is above the point (3,-3), so if we "assume" is a vertical parabola, then it'd be opening downwards.... anyhow that said, let's plug in those values.

\bf ~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(h,k)}\\\\ \stackrel{"a"~is~negative}{op ens~\cap}\qquad \stackrel{"a"~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}

\bf vertex~~(\stackrel{h}{2}~~,~~\stackrel{k}{1})\qquad \implies \qquad y = a(x-2)^2+1 \\\\\\ \stackrel{\textit{we also know that }}{(3~~,~~-3)} \begin{cases} x = 3\\ y = -3 \end{cases}\qquad \implies -3=a(3-2)^2+1 \\\\\\ -3=a(1)^2+1\implies -3=a+1\implies -4=a \\\\[-0.35em] ~\dotfill\\\\ ~\hfill y = -4(x-2)^2+1~\hfill
