Find the area of this triangle. Round to
DaniilM [7]

Answer:

63.3 square feet

Step-by-step explanation:

Let a = 20 ft, B = 15 ft, c = 9ft

s=\frac{a+b+c}{2}

s=\frac{20+15+9}{2}

s=\frac{44}{2}

s=22\: ft

Area \: of \:\triangle  =  \sqrt{s(s - a)(s - b)(s - c)}  \\  \\  = \sqrt{22(22 - 20)(22 - 15)(22 - 9)}  \\  \\= \sqrt{22 \times 2 \times 7 \times 13}  \\  \\= \sqrt{44 \times 91}  \\  \\ =  \sqrt{4,004}  \\  \\  = 63.2771681 \\  \\   \approx 63.3 \:  {ft}^{2}

Vitek1552 [10]
Hi there!

To solve this problem, we need to divide the total amount of tables by the amount of students:

40 / 10 = 4

So, we need 4 tables to seat 40 students. 

Hope this helps!

Which statements are true?<br>(look at picture)​
Makovka662 [10]

Answer:

D is true, E is true, F is true

Step-by-step explanation:

Hello,

n is an odd number it means that n = 2a+1 where a is integer

A

n^2-1=(2a+1)^2-1=4a^2+4a+1-1=4a(a+1)

this is <u>not</u> an odd number

B

n(n-1)=(2a+1)2a

this is <u>not</u> an odd number

C

(n-1)^2=(2a+1-1)^2=4a^2

this is <u>not</u> an odd number

D

n^2+2=(2a+1)^2+2=4a^2+4a+1+2=4a^2+4a+3= 2(2a^2+2a+1)+1

so this is an odd number

E

n(n-2)=(2a+1)(2a-1)=4a^2-1=4a^2-2+1=2(2a^2-1)+1

so this is an odd number

F

(n-2)^2=(2a+1-2)^2=(2a-1)^2=4a^2-4a+1 = 2(2a^2-2a)+1

this is an odd number

hope this helps
