To answer the question above,
Let n be the no. of sold wallet
1 wallet = $12
yesterday = n
today = n - 3
over the past two days = $396

an equation that models the situation: n x $12 + (n - 3) x $12 = $396
n x 12 + (n - 3) x 12 = 396
n x 12 + n x 12 - 3 * 12 = 396
2 x n x 12 - 36 = 396
n x 24 = 396 + 36
n x 24 = 432
n = 432 / 24

The answer is
Shannon sold n = 18 wallets yesterday.

A tabletop is in the shape of a trapezoid. The lengths of the trapezoid's parallel sides are 48 inches and 40 inches. The height

goldenfox [79]

The equation is
$area = \frac{1}{2} (a + b)h$
If you put in the numbers you get
$area = \frac{1}{2} (48 + 40) \times 24$
This comes to 1056. So the answer is 1056 in^2

Which expression represents the distance between point (0, a) and point (a, 0) on a coordinate grid?

o-na [289]

Answer:

$\sqrt{2} a$

Step-by-step explanation:

The distance between point (x1,y1) and (x2,y2) on a coordinate plane is given by expression $\sqrt{(x1-x2)^2+(y1-y2)^2}$

In the problem given coordinate points are

(0, a) and (a, 0).

Thus, distance between these points are given by

$distance = \sqrt{(x1-x2)^2+(y1-y2)^2}\\=>distance = \sqrt{(0-a)^2+(a-0)^2}\\=>distance = \sqrt{(a)^2+(a)^2}\\\\=>distance = \sqrt{2a^2}\\=>distance = \sqrt{2} a$
