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:

Angle y = 60°

Angle x = 65°

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

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:

m=15

Step-by-step explanation:

since side QS is 9 and side AC is 6 which is 1.5 times bigger so there is a dilation of 1.5 meaning all sides are 1.5 times bigger on the right triangle than the left triangle. Side AB is 10 so 1.5 times 10 is 15 so m=15

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

Answer:

two lawns.....

...........

Genesis can mow 2 lawns per hour.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Genesis mows in 1/6 hour =1/3 lawns

To find, mow per hour,

∴ in 1/6 hours =1/3 lawn,

⇒1 hour = 6×1/3 lawn

⇒1 hour = 2 lawns.

So, In 1 hour, Genesis can mow 2 lawns.

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:

2,275

Step-by-step explanation:

c=325m

Because for every meeting room there is 325 chairs and c=the total of chairs

and c=325(7) so c=2,275

so the answer is 2,275

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]

Step-by-step explanation:

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.
