Answer:

( \frac{11}{2}, 8)

Step-by-step explanation:

Find the midpoint using the midpoint formula

midpoint = [ \frac{1}{2}(3 + 8), \frac{1}{2}(2 + 14)] = ( \frac{11}{2}, 8)

Answer: (5.5, 8)

Step-by-step explanation:

We know that midpoint (x,y) of a line XY having points having points (x_1,y_1) and (x_2,y_2) is given by :-

x=\dfrac{x_1+x_2}{2}\ ;\ y=\dfrac{y_1+y_2}{2}

Then similarly, the midpoint of AB with endpoints A(3,2) and B (8,14)  will be :_

x=\dfrac{3+8}{2}\ ;\ y=\dfrac{2+14}{2}\\\\\Rightarrow\ x=\dfrac{11}{2}\ ;\ y=\dfrac{16}{2}\\\\\Rightarrow\ x=5.5\ ;\ y=8

Hence, the midpoint of AB with endpoints A(3,2) and B (8,14) = (5.5, 8)

A tennis ball weighs about 57.6 grams. about how many apuntes would 12 tennis balls weigh?
Ilia_Sergeevich [38]

Answer:

The weight of 12 tennis balls  =  691. 2 grams

Step-by-step explanation:

The weight of each  tennis ball =  57.6 grams

So, the weight of 12 balls    =    12 x ( weight of 1 ball)

                                              = 12 x 57.6 grams

                                              = 691.2 grams

⇒12 balls weigh 691.2 grams

Hence, the weight of 12 tennis balls  =  691. 2 grams

Leno4ka [110]

Answer:

<h2>84in²</h2>

Step-by-step explanation:

If the first one is 7 inches long, and 6 inches wide, and the second one is also 7 inches long, but is 6x2 inches wide, then what's the area?

6x2=12

So, Picture Frame 2 = 12 inches wide

Formula for finding area = LxW

L = 7

W = 12

7x12=84

So hence, your answer is 84in²

The area of the second frame is 84in²

Thanks!
