PLZ HELP! please answer both if you can!!

Answer:

0.324m^2 ; 18 ft

Step-by-step explanation:

Given the triangle :

Base (b) of triangle = 54cm

Height (h) of triangle = 1.2m

Area(A) of a triangle is given by:

0.5 * base * height

Base = 54cm = 54/100 = 0.54 m

Therefore,

A = 0.5 * 0.54m * 1.2m

A = 0.324m^2

2.) Average of the two bases in the trapezoid :

From the trapezium Given :

Base 1 = 15 feets

Base 2 = 7 yards

1 yard = 3 Feets

Therefore, base 2 in Feets = 7 * 3 = 21 Feets

Average of the two bases :

(21 Feets + 15 Feets) / 2

= 36 Feets / 2

= 18 Feets

Find the area of the parallelogram, trapezoid, rhombus, or kite. Round to the nearest tenth, if necessary.
Sergeeva-Olga [200]

Answer:

  • 69.3 yd²

Step-by-step explanation:

Area equation of the parallelogram

  • A = bh, where b- base, h - height

Looking at the picture, we can see the right triangle is isosceles as one of interior angles is 45°. It has hypotenuse of 7 and legs of h.

As per property of 45° right triangle the hypotenuse is √2 times the leg.

It gives us

  • h√2 = 7 ⇒ h = 7/√2 = 4.95 (rounded)

Now find the area

  • A = 14*4.95 = 69.3 yd²

You have 9 chairs arranged in a circle, and wish to seat 9 people (one person per seat). The one constraint is that person A can
stiv31 [10]

Answer:

30240 number of ways are there to seat them

Step-by-step explanation:

Total number of ways of arranging 9 people on 9 chairs  in circular manners = (9-1)! = 8! =

number of ways A sit always sit next to B = AB together makes a single and

                                                                       therefore total number of arrangements for this  = 7+(AB) = 8  that is 8  persons sitting in circular manner

number of ways = (8-1)! =7! = 5040

likewise number of arrangements for A and C will be = 5040

Total number of ways such that A cannot sit next to B or C = total ways of 9 persons - total number of A always sitting next to B - total number of ways always sitting next to C  = 8! - 7!-7!

                                        = 40320- 5040-5040

                                        = 30240
