tan =opposite/adjacent

In this case: tan =X , opposite=Y and adjacent= D

tan(x)=Y(opposite) /D(adjacent)

All terms in the equation are known except for 'D the distance'.

So the distance between the earth and the sun indicate by the symbol 'D' is equal to: y/tan(x)

Let the distance between the earth and the sun be denoted as 'z'.
From the trigonometric rules:
tan(theta)=opposite/adjacent

In this case: theta=x , opposite=y and adjacent=z

tan(x)=y/z
All terms in the equation are known except for 'z'.
therefore the distance between the earth and the sun denoted by the symbol 'z' is equal to: y/tanx

Answer:

Step-by-step explanation:

While working at his neighborhood math tutoring center researching the comprehension level of the students Dion investigated that the distribution of the student test scores are normally distributed with a mean of 79.13 and a standard deviation of 6.34. What is the probability that the student scores less than 60.11

We solve using z score formula

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

z = 60.11 - 79.13/6.34

GenaCL600 [577]

Answer:

7 pounds

Step-by-step explanation:

In order to find the answer to this question add the cost of a pound worth of almonds to the total amount of money she spent altogether in till you cannot add anymore.

7.00+3.50=10.50

10.50+3.50=14.00

14.00+3.50=17.50

17.50+3.50=21.00

21.00+3.50=24.50

=7lb

Check work:

3.50\times7=24.50

What is good ways to practice math without getting bored? Or stressed?
RUDIKE [14]

Answer: This depends on what you like and what you are studying. With any subject a way to have "fun" (the best you can with school) is by making a quizlet or kahoot with your math questions and answers. You will be learning and somewhat enjoying your time all in one! All subjects aren't for everybody but there are many more ways for you to practice your math while not being bored or stressed, these were just a few examples. Also if the reason you're stressed about math is because you don't understand it(this goes for any subject) then talk to you teacher or professor and they will help you.
