My math teacher time me is easier to do it after
Answer:
20% or .20
Step-by-step explanation:
There are a total of 10 cards in the sample.
Of these 10 cards there are 2 of them with the number 8 on them.
To find the probability, you divide the part (2) over the whole (10)
2/10 = .20
Then you can multiply by 100 to find the percent
(.20)(100) = 20%
Therefore, if the teacher were to select a card at random there is a 20% chance that it has the number 8 on it.

Answer:
? = √87 ≈ 9.33
Step-by-step explanation:
The square of the hypotenuse (h) of the small triangle is the sum of the squares of its legs.
h^2 = 5^2 + 12^2 = 25 +144 = 169
The square of the hypotenuse of the large triangle is also the sum of the squares of its legs.
h^2 +?^2 = 16^2
169 +?^2 = 256
?^2 = 256 -169 = 87
Taking the square root, we find the missing leg length to be ...
? = √87 ≈ 9.33
If you meant <span>25x + 10y =20.30, we can elim. the dec. fraction by mult. all 3 terms by 100:
2500x + 1000y = 2030
Then 1000y = 2030 - 2500x, or y = 2.03 - 2.5x
Without a second equation in x and y, you cannot simplify further, nor can you solve for a specific numerical value for either x or y.</span>
