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.

Answer:

The correct equation is 23n=65

Step-by-step explanation:

23n=65 means a number 'n' multiplied with 23 gives you the product 65.

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

y-3=1/3x -4

add add four

y+1=1/3x

divide 1/3 into 1

y+3=x

Answer:

x - 3y = 3

This is the answer in standard form.

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

Answer:

∠1=55°

Step-by-step explanation:

Since all the angles in a triangle have to add up to 180° we can make an equation

80°+45°+∠1=180°

∠1=55°

Answer:

Answer:

Earning 10,000 per month.

Step-by-step explanation:

Since a "180" usually refers to an opposite, the opposite of "losing 10,000 per month" would happen.

So, the company would be earning money instead of losing money.

Answer:

Step-by-step explanation:

iii) ∠AOE + ∠DOE +  ∠DOB = 180   {Straight line angles}

  67 + ∠DOE + 100 = 180

          ∠DOE = 180 - 167

         ∠DOE = 13°

ii) ∠BOC = ∠AOD    {Vertically opposite angles}

  ∠BOC = ∠AOE + ∠DOE

              = 67 + 13

  ∠BOC = 80°

i) ∠AOC = ∠BOD

∠AOC = 100°

Step-by-step explanation:

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

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.

2 is a prime number and 3 is a prime number

2×3=6×3=18

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

Knowing this... The answer is D,C,A,B
