Answer:
It will take 22.5 minutes to complete 1 mile
Step-by-step explanation:
From the question,
The marching band walks 1/15 miles in 1.5 minutes
First we will determine the miles cover in 1 minute
If the marching band walks 1/15 miles in 1.5 minutes
then, they will cover 
miles in 1 minute
Then,
miles
∴ 2/45 miles are covered in 1 minute
Now,
If 2/45 miles are covered in 1 minute
Then, 1 mile will be covered in 
minute
∴ 
Hence, it will take 22.5 minutes to complete 1 mile
Answer:
Answer:
Option B is correct.
Miguel should study for the Science quiz as he will do worse in that quiz by guessing.
Step-by-step explanation:
Miguel has to take two quizzes
1) 4 true or false questions on History with a 0.5 chance of acing the quiz
Expected number of correct questions = np
n = number of questions
p = probability of acing the test
Expected number of correct questions = 4 × 0.5 = 2
2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.
Expected number of correct questions = 0.2 × 3 = 0.6
It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.
A: a flow chart would best describe the steps
In the given question, it is given that ramp is 17 feet long, rises 8 feet above the floor, and covers a horizontal distance of 15 feet.
And we have to find the value of tan B.
And tangent of any angle is equal to the ratio of vertical by horizontal. That is:
tanB=8/15
And that's the required missing ratio for tan B.
