Step-by-step explanation:
The congruence theorems or postulates that could be given as reasons why triangles ABC and LMN are congruent are: LL, HL and SAS
How to determine the congruence theoremsFrom the figure, we can see that the hypotenuse of both triangles are congruent; this represents the HL theorem
Also, the acute legs of both triangles are congruent;
This represents the LL theorem
One angle is between two congruent sides in both triangles.
This represents the SAS theorem
Hence, the congruence theorems or postulates that could be used are: LL, HL and SAS

Answer:
H is the Answer
Step-by-step explanation:
Apply distance formula.
[tex](x {}^{2 } - {x}^{1} ) {}^{2} + ( {y}^{2} - {y}^{1} ) {}^{2} = d {}^{2} [/tex]
where d is the distance.
[tex]( - 5 - 7) {}^{2} + (0 - 5) {}^{2} = [/tex]

I. f(2) when f(x) = 3x + 4
II. f−1(4) when f(x) = 3x - 4 over 5
III. 3y − 6 = y + 10
Answer:
1). 10 2). 8/5 3). 8
Step-by-step explanation:
I. f(2) = 3(2) + 4
= 6 + 4
= 10
II. f(4) = 3(4) - 4/5
= 12 - 4/5
= 8/5
III). 3y - 6 = y + 10
2y - 6 = 10

Laurie is painting the walls of her kitchen. It took Laurie 3 hours to paint 20% of the walls in her kitchen. How many total hours did Laurie take to paint the walls of her kitchen?
Answer:
Total time taken by Laurie to cover all kitchen walls = 15 hours
Step-by-step explanation:
Given:
Time taken by Laurie to cover 20% of kitchen walls = 3 hours
Find:
Total time taken by Laurie to cover all kitchen walls
Computation:
Total time taken by Laurie to cover all kitchen walls = Time taken for 20%[100%/20%]
Total time taken by Laurie to cover all kitchen walls = 3[10/2]
Total time taken by Laurie to cover all kitchen walls = 3[5]
Total time taken by Laurie to cover all kitchen walls = 15 hours

r = Annual nominal interest rate as a decimal.
R = Annual nominal interest rate as a percent.
r = R/100.
n = number of compounding periods per unit of time.
t = time in decimal years; e.g., 6 months is calculated as 0.5 years

5. Given AADL AAKM with AD = 14, DK = 21, and
AL= 15. What is the measure of LM?
Answer:
22.5
Step-by-step explanation:
first of all, the first sign in the designations of the triangles is not an A. it is the Greek Delta (capital) sign. standing for "triangle" due to its shape.
as the diagram shows (and the description says correctly), ADL and AKM are similar triangles.
that means they have the same angles.
and in order to keep the same angles even when the lengths of the sides are different, the relative relation of the side lengths must be the same for all sides.
that means, if one side changes by a factor f, then both other sides must change by the same factor.
so, by checking the change factor for AD (to AK), we can then determine the change of AL to AM. and then we simply subtract AL from AM and get LM.
the original AD = 14.
AK = AD + DK = 14 + 21 = 35
the change factor f is then AK/AD = 35/14 = 5/2
in other words AD grew by a factor of 5/2.
AM is then created by applying the same factor to AL.
=> AM = 15 * 5 / 2 = 75 / 2 = 37.5
=> LM = AM - AL = 37.5 - 15 = 22.5

TWO points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6 cm long, find the scale used to draw the plan.
Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.

Sandy paid $27 for her new sweater. If the sweater was on sale for 25% off, what was the original price?
Answer:
The answer is $36
Step-by-step explanation:
Took the Star Math Test
Answer:
$36
Step-by-step explanation:
100% - 25% = 75%
75% as a decimal = 0.75
75% = 27
75% as a decimal = 3/4
So 3/4 x = 27
27 x 4 = 108
108 / 4 = 36

Carlos and his family left for the amusement park at 8:35 Ask Your Teacher The trip took 1 hour 55 minutes. What time did they arrive?
Answer:Carlos and his family arrived at 10:30
Step-by-step explanation:
The time Carlos and his family left for the amusement park =8:35
Since The trip took 1 hour 55 minutes., we have to add it to the time they left for the amusement park to now the time they arrived
8: 35 =8 hrs 35minutes
1 hr 55 minutes
90 minutes
but 90minues is greater than 60 so we convert to hours and minutres by dividing by 60 giving us
90/60=1.5hrs=1hr 30mins
8¹ hrs 35minutes
1 hr 55 minutes
10hrs 30 minutes
Therefore, They arrived at 10:30
A sample of 23 women athletes, aged 20 was taken. The systolic blood pressure of these women had an average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
Answer:
Step-by-step explanation:
average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
From the above question
Number of samples = 23 , less than 30,
Hence, we find confidence interval using t score
Confidence Interval using t score =
Mean + t score × standard deviation/√n
Step 1
We find the degree of freedom
= N - 1
= 23 - 1
= 22
