Answer:
Part A: this equation can only have 1 solution.
Part B:
3(2x - 7) = 3
⇔ 6x - 21 = 3
⇔ 6x = 3 + 21
⇔ 6x = 24
⇔ x = 24/6 = 4
Probability (P) is basically outcome, and chance. What are the chances of grabbing a red or blue marble?
Well, there IS a more complicated way to solve this, but let's go the easy way.
You calculate probability with this equation:
Probability=Events/Number of outcomes
If you want to find the probability of grabbing a red or blue marble, you first have to find all possible outcomes by adding ALL numbers together. 6+6+4=16. Next, find how many events you have. Well, you want to find red or blue. Add the number of red and blue marbles together. 6+4=10, so your equation now looks like: Probability=10/16
Now, just simplify.
10/16 can be divided evenly by 2 on both sides, so just do that, and you get:
5/8
You have a 5/8 chance, or a 0.625 chance of drawing a red or blue marble.
Answer:
6748'
Step-by-step explanation:
The long diagonal is the third leg of a triangle with the given side lengths and an angle between them that is the supplement of the given angle. Its length can be found from the Law of Cosines.
a^2 = b^2 +c^2 -2bc·cos(A)
a^2 = 3473^2 +4822^2 -2·3473·4822·cos(180° -72.23°)
a^2 = 45,535,553.83
a ≈ 6748.004
The longer diagonal is about 6758 feet long.
Answer:
z=-8
Step-by-step explanation:
38=2z+54
then subtract 54 from each side
-16=2z
then divide by 2
and you get z=-8
