PLEASE HELP Classify each pair of numbered angles as corresponding, alternate interior, alternate exterior, or none of these.
Drag and drop the choices into the boxes to correctly complete the table.
corresponding alternate interior alternate exterior none of these
Answer:
alternate exteriornone of these (consecutive exterior)correspondingalternate interiorcorrespondingStep-by-step explanation:
The above list is for the figures numbered 1-3 (left to right) on the top row, and 4-5 (left to right) on the bottom row.
__
"Alternate" angles are on opposite sides of the transversal. If the angles are between the parallel lines, they are "interior" (fig 4). If they are outside the parallel lines, they are "exterior" (fig 1).
"Corresponding" angles are found in the same direction from the point of intersection. Upper-left corresponding angles are seen in fig. 3; lower-right corresponding angles are seen in fig. 5.
The angles marked in figure 2 are "consecutive exterior" angles, also called "same-side exterior" angles. The applicable descriptive choice in this problem is "none of these".
Martina read that approximately 10% of all people are left-handed. She wants to design a simulation to approximate the probability of selecting exactly 2 right-handed people when 3 people are randomly selected.

Question 3 options: 10% 15% 20% 25%
Answer: 10%
Step-by-step explanation:
The probability of selecting exactly 2 right-handed people are approximately 20% of the time.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
The results of the simulation are shown.

Here, probability = 6/30
= 1/5
= 0.2
= 0.2×100
= 20%
Therefore, probability of selecting exactly 2 right-handed people are approximately 20% of the time.

A lawnmower that regularly sells for $150 is on sale for $120. By what percentage was the price decreased?
Answer:
20%
Step-by-step explanation:
Find the difference of both prices.
150 - 120 = 30
Calculate the ratio of the decrease in price to the original price.
30/150 = 0.2
Multiply the decimal by 100 to get your percentage.
0.2(100) = 20

A zookeeper is 6 and 1/4 feet tall. A young giraffe in her care is 9 and 3/8 feet tall. What fraction of the giraffes height is the zookeepers?
Answer:
3 1/8
Step-by-step explanation:
Subtract and then simplify
Answer:
Step-by-step explanation:
1. You know that:
- The zookeeper is 6 1/4 feet tall.
- The young giraffe is 9 3/8 feet tall.
2. Then, to calculate how many times as tall as the zookeeper is the girraffe, you only need to divide the height of the giraffe by the height of the zookeeper:
- Let's rewrite each height as a decimal number: divide the numerator and the denominator of the fraction and add the result to the whole number:
- Divide 9.375 feet by 6.25 feet, then you obtain the following result:

What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
On a coordinate plane,
Point B is at (- 8, 10),
Point C is at (8, 10),
Point D is at (2, - 2),
Point E is at (- 8, - 4).
Now, We know that;
The distance between two points (x₁ , y₁) and (x₂, y₂) is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
Thus, The length of side BC is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (8 - (-8))² + (10 - 10)²
⇒ D = √ 16²
⇒ D = 16
Thus, The length of side CD is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (2 - 8)² + (-2 - 10)²
⇒ D = √ -6² + (-12)²
⇒ D = √ 36 + 144
⇒ D = √ 180
⇒ D = 13.4
Thus, The length of side ED is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (2 - (-8))² + (-2 - (-4))²
⇒ D = √ 10² + 2²
⇒ D = √104
⇒ D = 10.2
Thus, The length of side BE is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (- 8 - (-8))² + (10 - (-4))²
⇒ D = √ 14²
⇒ D = 14
