Answer:
1:3
Step-by-step explanation:
it is a bit easy to get it out of decimal ratio, so multiply it by 10, which gives you 4:12, so now you have a bigger answer to work with, you can divide 12 by 4, which gives you 3, and a ratio of 1:3
So I’m only answering so I can ask you a question
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.
Hope this Helps!!!

Answer:
700 cubic feet
Step-by-step explanation:
Volume of scale model = 35 cubic feet
ratio of the dimensions of the model to the dimensions of the store was 1:20
Therefore
dimensions of the model/ dimensions of the store = 1/20
we know that in scaling
dimensions of the model/ dimensions of the store = Volume of scale model / volume of the actual department store
Now substituting the value of scale model in the above ratio equation we have
1/20 = 35/volume of the actual department store
=> volume of the actual department store = 35*20 = 700
Therefore volume of the actual department store is 700 cubic feet
