Answer:
1/3
Step-by-step explanation:
Ratios are basically comparisons of multiple numbers that shows their quantity relationship with each other. If we want to find the ratio of x to y, then the ratio is written as x : y or x/y.
Here, we want the ratio of adults to children. There are 3 adults and 9 children, so we have:
adults / children = 3 / 9 = 1/3
The answer is thus 1/3.

Answer:
Step-by-step explanation:
In order to solve this problem, we need to start by finding the probability of picking an oatmeal raisin cookies. Probabilities are found by using the following formula:
In this case, our number of desired events is the number of oatmeal raisin cookies we have available: 8.
Our number of possible events is the total number of cookies in the bag, which is:
6+9+5+8=28
so the probability is:
which simplifies to:
Next, we need to find the probability of picking one oatmeal raisin cookie again. This time we only have 7 oatmeal raising cookies and 27 cookies left in the bag, so our probability will now be:
So, the probability of picking an oatmeal raisin cookie at first and picking one of the same kind again is found by multiplying both probabilities.
So the probability that Dana randomly selects an oatmeal raisin cookie from the bag, eats it, then randomly selects another oatmeal raisin cookie is:
Given
two angles (150° and 12°) and the shortest side (12 cm) of a triangle
Find
the second-shortest side
Solution
Strategy: Make use of the Law of Sines to find missing side lengths when angles are known. To find the third angle, make use of the sum of angles of a triangle.
The sum of angles of a triangle is 180°, so we have
... 150° + 12° + C = 180°
... C = 180° - 162° = 18°
The law of sines tells us
... c/sin(C) = b/sin(B)
... c = sin(C)·b/sin(B) = sin(18°)·(10 cm)/sin(12°)
... c ≈ 14.9 cm
_____
We are calling the sides a, b, c. We are calling the angles opposite those sides A, B, and C.
