Answer:

9.562

Step-by-step explanation:

Use the Heron’s Formula to find the area of a triangle when all three sides are known (SSS). In the formulas below, S represents the semi-perimeter of the triangle, and ABC are the three given sides.

You must first know the semi-perimeter (S) before you are able to calculate the area.

S= 1/2 (A+B+C)

Area = √S(S-A)(S-B)(S-C)

In your case:

<u>semi perimeter </u>

= 1/2 (9+4+6)

= 19/2

= 9.5

<u>Area </u>

= √9.5(9.5−9)(9.5−4)(9.5−6)

= √91.4375

= 9.562

213 is 30% of what amount
WITCHER [35]
Start by calling the unknown amount 'x'. We can then set up a relationship to represent the question:

213 = (30\%) \times x
or
213=0.3x

and then solve for x, by dividing both sides of our equation by 0.3

\frac{213}{0.3}=\frac{0.3x}{0.3}
710=x

213 is 30% of 710

To check: 710 \times 0.3 = 213

At the banquet 450 people had chicken and 150 had pasta. What percent of people has pasta?
Liono4ka [1.6K]

25 percent of people had pasta.

First add 450 and 150 (which equals 600)

Next divide 600 by 150 (which equals 4)

Which means 150 is a fourth of six hundred, and a fourth is 25 percent.

Which leads to my answer of 25 percent
