Answer:

205.2

Step-by-step explanation:

First get the area's of the 3 triangles on top of the base, the formula is <u>base x height divided by 2</u>

10 x 9 = 90

90 / 2 = 45

Multiply the area of the 3 sides together :

45 x 3 = 135

Now find the area of the base triangle :

9 x 7.8 = 70.2

To find the surface area of the ENTIRE shape you have to add all the sides :

135 + 70.2 = 205.2

ollegr [7]

Answer:

x = 0 , x = 9

Step-by-step explanation:

to find the zeros let f(x) = 0 , that is

x(x - 9) = 0

equate each factor to zero and solve for x

x = 0

x - 9 = 0 ⇒ x = 9

The population of a town increased from 3450 in 2006 to 4650 in 2011. Find the absolute and relative (percent) increase.
netineya [11]

Answer:

15% increase per year.

Step-by-step explanation:

5,600 - 3,500 = 2,100

2,100 is what percent of 3,500?

2,100 = X*3,500

X =  2,100 / 3,500

X = .60 or 60%

An average of 15% increase per year.
