Answer:
3 are china dolls
Step-by-step explanation:
if you multiple 25 by 4 and since it is 12 percent out of one hundred we can juat divide 12 by to get 3 which is the answer
Answer:

Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)


If the three are to be next to each other,
First, we arrange the three

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:

So, the total arrangement, when they have to be next to one another is:


The probability is:


Expand




Express as percentage


Hello there!
Legs: The two smaller sides of a right triangle; the sides that meet at 90°.
In Pythagorean Theorem, all three sides of a right triangle have names and certain measurements that explain their names. The legs of a right triangle are the two smaller sides; they meet at a 90° angle and form a square to ensure the 90°. The bigger side of a right triangle is what we call the hypotenuse. The hypotenuse equals what the legs squared add up to. For example, we can take the three measurements:
12 cm, 5 cm, 13 cm
Since the two smaller numbers are 5 and 12, those would be our legs in the right triangle. Because 13 is the largest, it would be our hypotenuse. To identify the equivalence of the equation, we would square 5 and 12 to see if it equals up to 13 squared
5 squared is 25, and 12 squared is 144. Because 144 + 25 = 169, and 13 squared is 169, we know that the right triangle exists. If you need a further explanation, let me know and I will gladly assist you.
Answer: k=54/79
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 16/3k from both sides.
Step 3: Subtract 5/2 from both sides.
Step 4: Multiply both sides by 12/(-79).

From the given problem, I gather that there are only two groups of forces. These are:
13 lb, 35 lb, resultant force 30 lb
20 lb, 15 lb, resultant force 25 lb
We use the pythagorean theorem to determine if the three forces are grouped correctly, such that the resultant force is the hypotenuse.
Resultant Force = √(a² + b²)
So, for the first group,
30 ? √(13² + 35²)
30 ≠ 37.33
Thus, the first group does not pull at right angles to each other.
For the second group,
25 ? √(20² + 15²)
25 = 25
Thus, the second group does pull at right angles to each other.
