Find the area of a trapezoid. A. 39 square root 3 sq units B. 43.5 sq units C. 43.5 square root 3 sq units

LiRa [457]

Answer:

43.5√3 sq. units

Step-by-step explanation:

Base 1 of trapezoid is 10.

Base 2 of trapezoid is 16 + 3 = 19

The height = 3√3 (To get the height you had to multiply the number 3 from the bottom base of the trapezoid by the square root of three)

Now plug these numbers into the trapezoid formula: A = 1/2(3√3)(10 + 19)

Simplify to get: 43.5√3 sq. units

Hope this helps you understand!

Jimmy owns a small engine repair business. The revenue, in dollars, can be modeled by the equation y = 420 + 72x, where x is the

kozerog [31]

Answer:

5 hours

Step-by-step explanation:

Given

$y = 420 + 72x$ --- Revenue

$y = 24x^2 + 180$ --- Overhead cost

Required

Determine the hours for break even

To do this, we simply equate both expressions as follows:

$24x^2 + 180 = 420 + 72x$

Collect Like Terms

$24x^2 - 72x + 180 - 420 = 0$

$24x^2 - 72x -240 = 0$

Divide through 24

$x^2 - 3x - 10 = 0$

Expand:

$x^2 -5x + 2x -10 = 0$

Factorize:

$x(x -5) + 2(x -5) = 0$

$(x + 2)(x -5) = 0$

$x + 2 = 0\ or\ x - 5 = 0$

$x = -2\ or\ x = 5$

But x can't be negative because it represents time.

<em>So, x = 5 hours</em>
