Answer:

i. 24 sides

ii. 3960°

Step-by-step explanation:

Let the exterior angle be x.

x + 11x = 180°

12x = 180°

x = 15°

Hence the size of an interior angle is 11 times 15, which is 165°.

The formula for finding the sum of angles in an interior angle is this:

(n-2)180, with n being the number of sides the polygon has.

Hence, you can form this equation.

(n-2 )180 = 165n

180n-360=165n

-360=-15n

24=n

So, with there being 24 sides, the sum of all interior angles is 24 times 165 which equals 3960°

At 7:00 p.m., there are 1,000 home-team fans and 700 away-team fans at a football game. After 7:00 p.m, 15 home team fans arrive
OleMash [197]

Answer:

Therefore the ratio of home-team fan to away team fan at 8:00 p.m is

=109:67

Step-by-step explanation:

Initially , total home team fans =1000

and away team fans = 700.

7:00 pm to 8:00 pm = 1 hour = 60 minutes

Given that

Every 10 minutes the number of arrival home team fans is 15.

Then in 1 minutes the number of arrival home team fans is \frac{15}{10}

and in 60 minutes the number of arrival home team fans is \frac{15 \times 60}{10}  

                                                                                                 =90

Therefore total home team fans = (90+1000)=1090

Given that

Every 10 minutes 5 fans leave of away team  leave.

then in  1 minutes \frac{5}{10}  fans leave of away team  leave.

and In 60 minutes \frac{5\times 60}{10} =30  fans leave of away team  leave.

Since 30 away team fans leave.

Total away team fans = (700-30)=670

Therefore the ratio of home-team fan to away team fan at 8:00 p.m is

=1090:670

=109:67

<u>Step 1:  Pull a 7 from the top</u>

<u />\frac{7x + 42}{x^2 + 13x + 42}

\frac{7(x + 6)}{x^2 + 13x + 42}

<u>Step 2:  Factor the bottom</u>

<u />\frac{7(x + 6)}{(x + 7)(x + 6)}

<u>Step 3:  Cancel the top (x+6) and the bottom (x+6)</u>

<u />\frac{7}{x+7}

Mrs. Garcia’s students were asked to find 220% of 75. Each of the students had a different method.
ludmilkaskok [199]

Answer:

Colton.

Step-by-step explanation:

Amy: 220% is basically \frac{220}{100} which in decimal form, is 2.20.

Braden: 100% + 100% + 20% = 220%, so it is accurate.

Colton: 100%  + 10% + 10% = 120%, not 220%.

Dainielle: 100% of 75 is 75. Dividing the 100% of 75 by 5 makes a 20%. Adding 100% of 75 twice makes 200%. 200% + 20% = 220%, so it is accurate.
