What is the area of the figure? Answer in decimal form to the nearest hundredth.
sineoko [7]

Answer:

35.75 meters squared

Step-by-step explanation:

The area of a trapezoid is denoted by: A=\frac{(b_1+b_2)*h}{2} , where b_1 and b_2 are the bases and h is the height.

Here, the two bases are 7 1/2 and 5.5 meters and the height is 5.5. So, just plug in the values:

A=\frac{(7\frac{1}{2}+5.5)*5.5 }{2}

7 1/2 is the same as 7.5: A=\frac{(7.5+5.5)*5.5 }{2}=\frac{(13)*5.5}{2} =35.75

Thus, the area is 35.75 meters squared.

Hope this helps!

List the first three terms of this sequence: an = 3 • 5n – 1
Alexxandr [17]

Answer:

1st term = 14

2nd term = 29

3rd term = 44

Step-by-step explanation:

1st term = 3 x (5x 1) - 1

             = 3 x 5 - 1

             = 15 - 1 = 14

2nd term = 3 x ( 5 x 2 ) - 1

               = 3 x 10 - 1

                =30 - 1 = 29

3rd term = 3 x (5 x 3 ) - 1

               = 3 x 15 - 1

               = 45 - 1 = 44
