Answer:

-63/28 or 2 1/4

Step-by-step explanation:

when dividing you will be multiplying by the reciprocal of the second fraction. SO it will be...

-9/14 times 7/2

this is... -63/28

Answer:

-9/4

Step-by-step explanation:

   -9

  -----

   14

------------

     2

    ----

      7

To divide -9/14 by 2/7, invert 2/7 and multiply instead:

   -9        7

 ------- * -----

   14        2

Reducing, we get:

(-9)(1)

---------  = -9/4

Answer:

1x+5

Step-by-step explanation:

Work Shown:

n = number of questions = 8

p = probability of getting a question correct = 1/2 = 0.5

n*p = number of questions we expect Lee to get correct

n*p = 8*0.5

n*p = 4

We expect Lee gets about 4 questions correct.

4 question that lee guessed would be correct.

There  8 question of true and false.
Lee guessed every question.

Probability can be defined as ratio of favorable outcomes to the sample of events.

Here,
Probability of guessing right answer = 1/2 = 0.5
Probability of lee guessing right answer out of 8 question.
= 0.5 x 8
= 4

Thus, 4 question that lee guessed would be correct.

Answer:

L : H Ratio = 3 : 8  , L as a fraction of H = 3/8

Step-by-step explanation:

Let the no. of Leon's tropical fish be = L

Let the no. of Harry's tropical fish be = H

Given : 2/3 L = 1/4 H

L / H = 1/4 (3/2)

L : H = 3 : 8

Let total fishes or common ratio = x

L = 3/11  (x) , H = 8/11 (x)

Fraction L / H = [ 3/11 (x) ] / [ 8/11 (x) ]

L / H = 3/8

Answer:

  30 miles

Step-by-step explanation:

The Law of Sines is used for this purpose. The angle at R is the difference ...

  180° -(23° +34°) = 123°

Then the length r satisfies ...

  ST/sin(R) = RT/sin(S)

  ST/sin(123°) = (20 mi)/sin(34°)

  ST = (20 mi)sin(123°)/sin(34°) ≈ 30.00 mi

The length of r or ST is 30 miles.
