Answer:

Step-by-step explanation:

First convert the mixed fractions to improper fraction.

Then find the Least common denominator. Here LCD = 100

Then find equivalent fractions and subtract

$32\dfrac{3}{10}-12\dfrac{1}{100} = \dfrac{323}{10}-\dfrac{1201}{100}\\\\\\
=\dfrac{323*10}{10*10}-\dfrac{1201}{100}\\\\\\
=\dfrac{3230}{100}-\dfrac{1201}{100}\\\\\\
=\dfrac{3230-1201}{100}\\\\
=\dfrac{2029}{100}\\\\
=20\dfrac{29}{100}$

PLEASE HELP!! Find the area of the following triangle enter the exact answer as a decimal

Marta_Voda [28]

Answer:

75.06239187

Step-by-step explanation:

1/2bh= Area of a Triangle

6^2+b^2=8.5^2 because we are missing a side we need to use the pythagorean theorem.

36+b^2=72.25

b^2=36.25

b=6.02

6.02+19= base

25.02

Now area

1/2bh

1/2 (25.02*6)

25.02*6= 150.1247

150.1247/2= 75.06239187 is Area

The above decimals before area are rounded.
