Answer:

19.81cm^2

Step-by-step explanation:

To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:

sqrt(p*(p-a)*(p-b)*(p-c))

Plugging the values into this formula gives 19.81cm^2.

Donna takes classes at both Westside community college and pinewood community college. at westside , class fees are $98 per cred
Alex777 [14]

Answer:

Expression for the combined total dollar amount she paid for her class fees is  (2185 - 17 w)

Step-by-step explanation:

Let Donna  is taking w credit hours at Westside.

Total combined credit hours at two schools =  19 hours

So, the number of credit hours at Pinewood  =  19 - w

The per hour fees credit of Westside community college = $98

So, the total fees paid for w hours  = w x Fees per hour

= w ( $98)  = $(98w)

⇒The fees Donna pays at Westside community college =  $ (98 w)

The per hour fees credit of Pinewood community college = $115

So, the total fees paid for (19 -w) hours  = (19 -w) x Fees per hour

= (19 -w) ( $115)  = $(2185 - 115 w)

⇒The fees Donna pays at Pinewood community college =$(2185 - 115 w)

Hence, the total fees paid by Donna

= Fees at Westside + Fees at Pinewood

= $ (98 w)  + $(2185 - 115 w)

= $(2185 - 17 w)

Hence, expression for the combined total dollar amount she paid for her class fees is $(2185 - 17 w)
