In any polygon with number of sides = n, the sum of measures of its internal angles is equal to (n-2)*180

Now, for a nonagon:
number of sides = 9
sum of internal angles = (9-2)*180 = 1260 degrees

We are given the measures of seven of its angles and we know that the other two are equal. Assume that each angle of the remaining two angles has a measurements = x degrees

Therefore:
sum of angles = 138 + <span>154 + 145 + 132 + 128 + 147 + 130 + x + x
1260 = 974 + 2x
2x = 1260 - 974
2x = 286
x = 143 degrees

Based on the above calculations:
The measure of each angle of the remaining two angles is 143 degrees</span>

In 2007 the population of the town of Cartersville was 24,455. The population growth can be represented by the formula P = 24,45

Triss [41]

P = 24455 (1.03)x
30,000/24455 (1.03) < x
The year must be > 1.19 + 2007, or 2008.19, which means in 2009, or in 2008 + 3 months

During the school year, a bus driver made 7 trips to the museum. The distance from the school to the museum is 36 miles. Write a

bagirrra123 [75]

Given:

Number of trips = 7

Distance from the school to the museum = 36 miles.

To find:

Write and solve equations to find how many miles the bus driver drove for the 7 trips.

Solution:

Let x be the number of trips and y be the total number of miles the bus driver drove.

Distance from the school to the museum = 36 miles.

1 trip means from the school to the museum and then from the museum to the school.

Distance covered in 1 trip = 2×36 = 72 miles.

Distance covered in x trips = 72x miles.

$y=72x$

Substitute x=7 in the above equation to find the total distance the bus driver drove for the 7 trips.

$y=72(7)$

$y=504$

Therefore, the bus driver drove 504 miles for the 7 trips.

A scale drawing of a park is 30 inches long and 24 inches wide. On the drawing, 1 inch is equal to 250 feet What are the actual

chubhunter [2.5K]

1 inch equals 250 feet.

Multiply the inches on the map by 250 to get total feet.

30 x 250 = 7,500 feet

24 x 250 = 6,000 feet

The park is 7,500 feet long by 6,000 feet wide
