Remark
Notice you are working with minus signs. You final answer must be "smaller" than what you started out with. In other words, your final answer must be more negative.
Givens
Beginning level below sea level = -1260 feet
rate of descent = 5 feet per minute
Number of minutes = 12 minutes
Equation
Final level = initial level - rate * time Substitute givens into equation.
Solution
Final Level = - 1260 - 5*12
Final Level = - 1260 - 60
Final level = - 1329
Answer: - 1320 feet
Answer C, .6
Remember the acronym SOHCAHTOA. In particular the theee letter we want to look at are CAH. The C means Cosine, aka. Cos, and the A means adjacent, which shares the same meaning as next to, and the H means hypotenuse, which the last two refer to sides of the triangle. Using the acronym CAH, it helps to remember the Cosine ratio Cos(x)=A/H, meaning the cosine of x equals the adjacent side over the hypotenuse, with x being the angle in focus. Once that’s known, we can create a simple equation. In this problem, your x is angle A, the adjacent side measures .6, and the hypotenuse measures .5, which make up every variable we need to solve for x.
Once that’s plugged into the equation described before, we get Cos(A)=.3/.5 (*you may want to put parenthesis around the decimals in the numerator and denominator, I dont recall for sure but that being there or not might give you a different answer, if it does then the answer using parenthesis is right). From here on, because the question only asks for the cosine of a, figuring it out is as simple as simplifying .3 over .5. .3 is 60% or .6 of .5 which makes .6 your answer, which is the way to figure it no calculator.
Happy to use my semester of pre trig and trig to some good.
Probability is simply how likely something is to happen.
Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
The best example for understanding probability is flipping a coin:
There are two possible outcomes—heads or tails.
What’s the probability of the coin landing on Heads? We can find out using the equation P(H) = ?P(H)=?P, left parenthesis, H, right parenthesis, equals, question mark.You might intuitively know that the likelihood is half/half, or 50%.
Tips
The probability of an event can only be between 0 and 1 and can also be written as a percentage.
Real world problem for 11x = 385
Sam brought home 385 packs of string for the party. At the party, Sam invites 11 people, and wants to give each person the same amount of string. How much string does each person get?
Answer:
12+x
Step-by-step explanation:
This is marli- []
|
/\
Marli is 12
but lets say that Marli's brother is 5 yrs older than her just for fun
To find marli's bro's age when her bro is 5 yrs older than her, we would add 5 and 12 right?
the same thing applies when there's a variable in place of a number
DO NOT GET CONFUSED, DO EXACTLY THE SAME THING IF THERE HAD BEEN A NUMBER INSTEAD OF A VARIABLE
so
marli's bro= 12+x
Hope This Helps!!!!!
