The floor of a triangular room has an area of 32 1/2 sq.m. If the triangle’s altitude is 7 172 m, write an equation to determine
sineoko [7]

Answer:

\frac{(2)A}{h} =b

b=0.00906m

Step-by-step explanation:

Hello! To solve this exercise we must remember that the area of ​​any triangle is given by the following equation

A=\frac{bh}{2}

where

A=area=32.5m^2

h=altitude=7172m

b=base

Now what we should do take the equation for the area of ​​a rectangle and leave the base alone, remember that what we do on one side of the equation we must do on the other side to preserve equality

A=\frac{bh}{2} \\\frac{2}{h} A=\frac{bh}{2} \frac{2}{h} \\

\frac{A(2)}{h} =b

solving

\frac{2(32.5)}{7172} =0.0090[tex]\frac{A(2)}{h} =b\\b=0.00906m

Based on the populations of the town from 2000 to 2008, the average rate of change of the population between 2002 and 2004 is -6.1%

The average rate of change between 2002 and 2006 is -4.88%

<h3>What is the average rate of change?</h3>

The average rate of change can be found as:

=Change in population / Population in base year

The average rate of change in population between 2002 and 2004 is:

= (77 - 82) / 82

= -6.1%

The average rate of change in population between 2002 and 2006 is:

= (78 - 82) / 82

= -4.88%
