8. Calculate the length of r or st
Answers
9514 1404 393
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.

Answers
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

An 8-question true or false quiz is given to a class. If Lee guessed every question,
how many would she expect to be correct?
Answers
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.
