supplementary angles are when two angles sum up to 180 degrees.

∠x and ∠y are supplementary angles

===============

∠x + ∠y = 180°∠x + 116° = 180°∠x = 180° -  116°∠x = 64°

Answer:

64°

Step-by-step explanation:

Supplementary angles are two angles that add up to 180°.

∠x + ∠y = 180° <== substitute 116° for ∠y

∠x + 116° = 180° <== subtract 116 from both sides

     - 116    - 116

∠x = 64° <== measure of ∠x

Therefore, the measure of ∠x is 64°

creative writing: mean absolute deviation of 2.7

In which elective were her scores the most spread out?


art

creative writing

Spanish

Answer:  creative writing

Explanation:

MAD = mean absolute deviation

The larger the MAD, the more spread out the scores will be.

Therefore, Maggie has the most spread out scores in her creative writing class.

By definition of vertically opposite angle, the value of x is,

⇒ x = 42

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

Angles S and T are vertical angles.

And, The angle S has a measure of (x - 2)°, and angle T has a measure of 40°.

Now, We know that;

Vertically opposite angles are equal to each other.

Hence, We get;

⇒ ∠ S = ∠ T

⇒ (x - 2)° = 40°

⇒ x - 2 = 40

⇒ x = 40 + 2

⇒ x = 42

Thus, By definition of vertically opposite angle, the value of x is,

⇒ x = 42

Zoe considers the lunch choices as she looks at the menu. What is the probability that she will choose cheese pizza, apple, milk?

Meal: Cheese Pizza, Cheeseburger, Hotdog, Salad

Side: Banana, Apple, Yogurt

Beverage: Milk, Water, Juice

Answers

Answer:

1/36

Step-by-step explanation:

Meal: 4 choices

Side: 3 choices

Beverage: 3 choices

Total number of possible combinations: 4 × 3 × 3 = 36

The specific combination of cheese pizza, apple, and milk is 1 of the 36 possible choices.

p(cheese pizza, apple, milk) = 1/36

Answer:

e

Step-by-step explanation:

We first have to find out how many outcomes there are in total. That means finding out how many meals, sides, and beverages there are.

Meals: cheese pizza, cheeseburger, hotdog, and salad (4)

Sides: banana, apple, and yogurt (3)

Beverages: milk, water, and juice (3)

4 x 3 x 3 = 36

There are 36 possible outcomes.

We need to find the probability that Zoe will choose cheese pizza, an apple, and milk. Those are three outcomes.

The probability is 3/36.

The fraction 3/36 can be simplified to 1/12.

Robert had some friends at his house after school. His mom cut up 2 pies for them to eat. If she cut each pie into fourths, how many pieces will there be? Choose the model that represents the answer.
1/4
8/8

4/4

NO LINKS!!!!!)

Answers

Answer:

8/8

Step-by-step explanation:

There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).

Basically, multiply how many fourths (four per pie) by how many pies there are.

4 x 2 = 8

There are 8 pieces.

8/8 because with there being 2 pies with 4 slices each then 4+4=8 so it’s 8/8
