Answer:

EF = 2.9

Step-by-step explanation:

The geometric figures are similar so we can use the similarity ratio to calculate the length of EF:

GF/ CB = EF/AB

5/29 = EF/17 cross multiply expressions

29EF = 85 divide both sides by 29

EF = 2.9 approximately

Answer:

616 square centimeters

Step-by-step explanation:

Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.

Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.

Multiply 14 squared by 22/7:

(22/7)(14^2)

This gives us (22/7)(196); (4312/7); 616.

Therefore, the area of the circle is approximately 616 square centimeters.

6x+4y=12 into y=my+b
kirza4 [7]
6x + 4y = 12...subtract 6x from both sides
4y = -6x + 12 ...divide both sides by 4
(4/4)y = (-6/4)x + 12/4...reduce
y = -3/2x + 4 <== y = mx + b
