Answer:

68 ft

Step-by-step explanation:

this problem is asking for perimeter so instead of LxW

you would do L+L+W+W

(13 + 13 + 21 + 21) = 68

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°

Answer:

Answer: Un alambre de acero de 1.5 m se estira 2.0 mm con fuerza F. El diámetro del alambre de acero es 4.0 mm. El módulo de Young del acero es 2.0 x 1011 Nm-2. Determine la fuerza F aplicada sobre el alambre.

Step-by-step explanation:

let's firstly convert the mixed fractions to improper fractions, and then subtract.

[tex]\stackrel{mixed}{8\frac{1}{9}}\implies \cfrac{8\cdot 9+1}{9}\implies \stackrel{improper}{\cfrac{73}{9}}~\hfill \stackrel{mixed}{6\frac{7}{8}}\implies \cfrac{6\cdot 8+7}{8}\implies \stackrel{improper}{\cfrac{55}{8}}\\\\[-0.35em]~\dotfill\\\\\cfrac{73}{9}-\cfrac{55}{8}\implies \stackrel{\textit{using}\stackrel{LCD}{72}}{\cfrac{(8\cdot 73) - (9\cdot 55)}{72}}\implies \cfrac{584-495}{72}\implies \boxed{\cfrac{89}{72}\implies 1\frac{17}{72}}[/tex]

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.

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.

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

Answer:

Step-by-step explanation:

50 + 5x = 20 + 8x

20 + 8x = 50 + 5x

3x + 20 = 50

3x = 30

x = 10 students

50 + 5(10) = 50 + 50 = $100

answer is D

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

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.

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

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

Answer:

1263 seconds

Step-by-step explanation:

100 meters = 12.63 seconds

multiply both sides by 100 since

100*100= 10,000 meters

12.63*100= 1263 seconds

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

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
