Option A:

The another name for ∠1 is ∠JLK.

Solution:

How to Label Angles :

There are two main ways to label angles:

1. Give the angle name by a number or a lower case letters.

2. The second way to name the angle is indicating by the vertex.

Usually the angle is denoted by three letters.

First letter and the second letter denotes the arms of the angle and the middle of the letter denotes the angle (its vertex).

To find the another name for ∠1.

The arms of the angle are LJ and LK and the vertex is L.

So, the name of the angle is ∠JLK.

Middle letter is the actual angle.

Therefore the another name for ∠1 is ∠JLK.

Option A is the correct answer.

Miguel plots points A, B, and C in the coordinate plane.
serg [7]

Answer:

part a: 5

part b: no, ABC is not an equilateral triangle

Step-by-step explanation:

part a: if you do the distance formula for points A and B, you get 5

part b: using the distance formula again, points A to B and points A to C are both 5, but points B to C is 6, therefore it's not equilateral because all the sides have to be the same length

</span>
f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2 (sixth option)
</span>
f(n)=f(1)+2.50(n-1)
f(n)=7+2.50(n-1)
f(n)=7+2.50n-2.50
f(n)=2.50n+4.50 (fifth option)

Answers:
Fifth option: f(n)=2.50n+4.50, and
Sixth option: f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2</span>

Ji-Hun and Kana are running a marathon. Due to the volume of people running, the starts occur in waves. Kana starts at 9:35 a.m.
iris [78.8K]

Answer:

23.52 miles

Step-by-step explanation:

Let us find the number of miles that they would have run.

Kana starts at 9:35 a.m. and runs at an average rate of 7 mph.

Let the time she has spent so far be t.

Speed is given as:

s = d / t

where d = distance and t = time

=> d = s * t

Therefore, for Kana:

d = 7 * t = 7t _____________(1)

Ji-Hun starts at 10:00 am (25 minutes after Hannah) and runs at an average rate of 8 mph.

25 minutes = 25/60 hour = 0.42 hour

So, his time (compared to Kana's) is t - 0.42.

therefore, for Ji-Hun:

d = 8 * (t - 0.42)

=> d = 8t - 3.36 ____________(2)

Equating (1) and (2):

7t = 8t - 3.36

=> 8t - 7t = 3.36

t = 3.36 hours

Therefore, let us find d:

d = 7 * 3.36 = 23.52 miles

So, Ji-Hun will catch up to Kana after 23.52 miles.
