NONONOYESNOThe mid point of this segment can be derived by drawing diagonals across the 4 vertex LMNK.Generally
1)
OP is a segment bisector.
NO
OP is not a segment bisector because it those not divide segment LKMN in to two equal parts.
2)
OP is a perpendicular bisector.
NO
OP is not a perpendicular bisector because a perpendicular bisector is a bisector that cuts a segment into two equal parts and create an angle to the normal
3)
OP is an angle bisector
NO.
Because OP those not divide any angles into two equal parts
4)
O is the vertex of a pair of congruent angles in the diagram.
YES
Because O lines in between two angles of the same degree()

If Kyle earns $12.50 per hour, how many hours did he work if he earned a total of $400. Set up an equation and solve. Let x = hours.
Answer:
32.
Step-by-step explanation:
Here is the equation I used. (x = hours)
$400 = $12.50x
To find how many hours he needs to work, divide both sides by 12.50 to get x by itself.
400/12.50 = 12.50x/12.50
Which equals:
32 = x

Since the card has $0 minimum payments for the first 4 years it is active, Emma wonders how much it will cost her if she
doesn't pay off the $300 balance until after college. How much will she owe in 4 years?
Type the correct response in the box. Use numerals instead of words. Round your answer to the nearest dollar.
In 4 years, Emma will owe about $
Answer:
$544.61
Step-by-step explanation:
Edmentum
In 4 years, Emma will owe about $544.61 to the credit card company.
The model for Emma's debt in 4 years is given as:
FV = P(1+r/n)^nt,
where:
P = principal ($300)
r = the interest rate (15%)
t = the time in years (4 years)
n = the number of times the interest is compounded per year (12)
However, we can solve the problem with an online financial calculator as follows:
Data and Calculations:N (# of periods) = 48 (4 x 12 months)
I/Y (Interest per year) = 15%
PV (Present Value) = $300
PMT (Periodic Payment) = $0
P/Y (# of periods per year) = 12
C/Y (# of times interest compound per year) = 12
Results:
FV = $544.61
Total Interest = $244.61
Complete Question:Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the terms of her credit card:
It has a 15% annual interest rate.The interest is compounded monthly.The card has $0 minimum payments for the first four years it is active.Thus, in 4 years, Emma will owe $544.61 to the credit card company.

Brooke spent 3/4 hours playing her flute each day for 7 days. How many hours did she play her flute in all
Answer:
5 and 1/4 hours or 5 hours and 15 minutes
Step-by-step explanation:
She played her flute 3/4 hours every day for 7 days, so to find the total number of hours we can multiply 3/4 by 7 to get 21/4. This is equal to 5 and 1/4 hours, or 5 hours and 15 minutes.
Answer: 5.25 hrs
Step-by-step explanation: 3/4 of an hour is 45 min. 45 min x 7 days is 315 min which is 5 hours and 15 min or 5.25 hrs

Hope it's helpfulFind the mean, median, mode, and range of the data set.
9, 3, 15, 7, 2, 4, 3
If necessary, round your answers to the nearest tenth.
Answer:
Step-by-step explanation:
Mean = Sum of data ÷ number of data set
[tex]=\dfrac{9+3+15+7+2+4+3}{7}\\\\=\dfrac{43}{7}\\\\= 6.14\\\\= 6.1[/tex]
Median:
Arrange the data in ascending order:
2 , 3 , 3 , 4 , 7 , 9 , 15
Middle term is the median of the data set
Median = 4th term = 4
Mode:
Mode is the data whose is frequency is more.
So, mode = 3
Range = Maximum - minimum
= 15 - 2
= 13
