Which scenario provides the most direct application of the Hypotenuse-Leg congruence criteria?
A.) two isosceles triangles congruent bases and base angles
B.) two equilateral triangles, each of which has 60 angles and 3-inch sides
C.) two 45 degrees -45degrees-90degrees triangles with congruent sides opposite to the right angle
D.) two right angles, each of which has a 4-foot side opposite the right angle and a 3-foot leg
The Hypotenuse-Leg congruence criteria is (D) two right angles, each of which has a 4-foot side opposite the right angle and a 3-foot leg
Two triangles are said to be congruent if they have the same size and shape. Hence, corresponding sides and angle are congruent to each other.
The Hypotenuse-Leg congruence theorem states that two right triangles are congruent if the hypotenuse and leg of one triangle is equal to the hypotenuse and leg of another triangle.

What is division ?
Division is the process of breaking a number up into equal parts, and finding out how many equal parts can be made.
a) The real world problem can be given as " With [tex]2\frac{1}{2}[/tex] liters of petrol available , you can fill 0.25 liter of petrol in a time by a gallon in a tank. how many times you need to use gallon to fill the tank of capacity [tex]2\frac{1}{2}[/tex] liters . "
b)
We know that in a division :
Dividend ÷ Divisor = Quotient
Let x be the quotient.
Then , the equation can be written as :
x = [tex]2\frac{1}{2}[/tex] ÷ [tex]\frac{1}{4}[/tex]
c)
Solving the real world problem as given in part (a).
If we solve it we get : no. of times we need to fill gallon :
= [tex]2\frac{1}{2}[/tex] ÷ [tex]\frac{1}{4}[/tex]
= [tex]\frac{5}{2}[/tex] ÷ [tex]\frac{1}{4}[/tex]
= 10 times
The quotient will be 10.
Therefore , the answers are :
a) The real world problem can be given as mentioned above in part a.
b) The equation can be written as : x = [tex]2\frac{1}{2}[/tex] ÷ [tex]\frac{1}{4}[/tex]

How many ways can 7 students be selected from an organization of 30 to attend a national conference?
Determine the number of possibilities for selection. Express your solution in a complete sentence reflective of the scenario.
The number of possibilities for selection is 2,035,000 ways
This question has to do with the combination
Given the following parameters
Total number of students = 30 students
If 7 students are to be selected from a pool of 30 students, the number of ways this can be done is expressed as:
30C7 = 30!/(30-7)!7!
30C7 = 30*29*28*27*26*25*24*23!/23!*7!
30C7 = 30*29*28*27*26*25*24/7!
30C7 = 10,260,432,000/5040
30C7 = 2,035,800
This shows that the number of possibilities for selection is 2,035,000 ways

epic gamer question i'll mark brainliest
It takes Rick, traveling 36mph, 40 minutes longer to go a certain distance than it takes Evelyn traveling at 84mph. Find the distance traveled
d = r · t and we know that the distance is the same.
Let x = time it takes Evelyn (in hours, since the rate is mph).
Evelyn's distance is 84x.
Rick's distance is 36·(x+2/3) since 40 minutes longer is 2/3 of an hour longer
84x = 36(x+2/3)
84x = 36x + 24
48x = 24
x = 1/2
So it takes Evelyn 1/2 an hour, meaning the distance is 84(1/2) = 42 miles
To confirm this, it would take Rick 42/36 hours or 1 and 1/6 hours. That's 70 minutes, which is 40 minutes longer than Evelyn's 1/2 hour trip.
The distance is 42 miles.
Learning Task 2: Solve each proportion
1) 5/12 = 35/ n
2) n/ 52 = 180/ 120
3) 18/n = 21/28
4) n/4 = 24/6
5) 10/16 = n/56
Bonjour,
1) 5/12 = 35/ n
(5/12) /35 = n
5/12 * 1/35 = n
5/420 =n
1/84 =n
2) n/ 52 = 180/ 120
n= (180*52)/120
n=9 360/120 = 936/12 = 78
3) 18/n = 21/28
n = (21/28)/18
n = 21/28 * 1/18
n= 21/504 = 7/168= 1/24
4) n/4 = 24/6
n= 24/6 * 4
n= 96/6 =16
5) 10/16 = n/56
n= 10/16 * 56
n= 560/16
n= 35

7 terms
nth term is a + (n - 1)*d
= 4 + (n -1 )*6
= 4 + 6n - 6
= -2 + 6n
so sigma notation would be
∑-2 + 6n
u can also check terms
n = 1 -> -2 + 6 = 4
n = 2 -> -2 + 6*2 = 10
n = 3 -> -2 + 6*3 = 16

Answer:
0.5 can also be written as 1/2 so we can eleminate the ones that are greater than 1/2 and put them ahead of 0.5 on the number line.
Since 2/3 is approximately 0.666666666666 we can put that above 0.5
2/5=0.4
1/4=0.25
1/10=0.1

solve for x and y then find the measurement of each angle
Answer:
x = 10
y = 40
Step-by-step explanation:
DE is a straight line so the sum of angles DBA and ABE is equal to 180
13x - 18 + 5x + 18 = 180 add like terms
18x = 180 divide both sides by 18
x = 10
Same rule applies when calculating value of y
3y - 52 + 2y + 32 = 180 add like terms
5y - 20 = 180 add 20 to both sides
5y = 200 divide both sides by 5
y = 40
