Answer:

41. s = semiperimeter

s = (a + b + c) /2

s = (120+170+250) /2

s = 270m

d is the correct option.

42. b is the correct option.

43. P = a + b + c

P = 120+170+250

P = 540m

a is the correct option.

44. A = √s((s-a)(s-b)(s-c))

=√270((270-120)(270-170)(270-250))

=9000m²

d is the correct option.

45. length of wire=P - space for gate

= 540 - 3

=537m

b is the correct option.

Find the midpoint between the points (7, -2) and (-4, 2). Write your answer in the proper form using parentheses
Elan Coil [88]

Answer:

( 1.5, 0)

Step-by-step explanation:

1. Find the coordinates ; in this case (7,-2) and (-4, 2)

2. Plug it into the formula (x1 + x2 ÷ 2 ) , (y1 + y2 ÷ 2)

3. ( 7 +  -4 ÷2) = 1.5    And    ( -2 + 2 ÷ 2) = 0

4. Therefore, the midpoint is ( 1.5, 0 )

The diameter of the circular base of a spot is 6 inches what is the closet approximation of the area base
AlladinOne [14]

Answer:

A≈28.26 in^2

Step-by-step explanation:

We know the diameter is 6

We can find the radius

r = d/2

r =6/2 =3 inches

The area of a circle is given by

A = pi *r^2

A = pi*3^2

A = pi*9

We will use 3.14 to approximate pi

A ≅(3.14) *9

A≈28.26 in^2
