Help me guys its test

d.12

Step-by-step explanation:

The interior angles of a polygon is given by the formula {180°(n-2)}/n where n is the number of sides

We already know the interior angles is 150° so we do that substitution

150=180n-360/n (cross multiply)

150n=180n-360

360=180n-150n

360=30n (divide both sides by 30)

n=360/30=12

Ezra is right

Annabelle did not feed the dog enough food.

Step-by-step explanation:

Annabelle and Ezra have a dog that eats 3/4 of a cup of food every morning. Annabelle lost the 1/4 cup so she used the 1/3 cup and gave him 2/3 of a cup of food. Ezra says that Annabelle did not feed the dog enough food. Annabelle says she gave him more than enough. Who is right? Explain how they can compare the fractions to figure out who is correct.

Food eaten by the dog=3/4

1/4 of x=3/4

1/4x=3/4

x=3/4 ÷ 1/4

=3/4 * 4/1

=12/4

=3

Annabelle fed the dog with 1/3 of a cup

1/3 of x =2/3

1/3x=2/3

x=2/3 ÷ 1/3

=2/3 × 3/1

=6/3

x=2

Normal feeding of the dog

3/4 of a cup =0.75

What Annabelle fed the dog

2/3 of a cup=0.67

Therefore, Annabelle didn't feed the dog enough food

Ezra is right

Annabelle did not feed the dog enough food.
