This is a right triangle. All side lengths of a right triangle can be found using Pythagorean Theorem.
1. 4^2+8^2=c^2, so this means that c=
80, so your first answer is 8.944.
2. 1600-625=a, so a is the square root of 975, which is 31.22.
3. c^2-a^2=b^2: 122,500-40000, so b^2 is 287.23.
4. 56.25+156.25=c^2, so c is 14.58
5. c^2-b^2=a^2, so a^2 is 67.8
Hope this helped.

I got it right..................
By using the PEMDAS order of operations, we get 3(6+7) = 39.
The equation be 3(6+7) then the correct answer is 34.
<h3>What is PEMDAS order of operations?</h3>
The order of operations exists as a law that describes the proper sequence of stages for estimating a math expression. We can recognize the order utilizing PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right).
Given: 3(6+7)
By using the PEMDAS order of operations, we get
(6+7) = 13
Then we get
3(6+7) = 3 13
= 39.
Therefore, the value of 3(6+7) = 39.

Answer:
Step-by-step explanation:
1)
Probability for flipping one coin is 1/2
Probability for flipping two coins should be about 1/2 * 1/2 which is 1/4
There is a 1/4 chance
2)
First you must find the sum of all the marbles which would be 20
Now, put the blue marbles over the sum of 20 which is
5/20 or simplified to 1/4 which is the probability of choosing a blue marble
3)
If the probability of landing on yellow is 4/9, whatever is left is the probability of not landing on yellow which is 5/9
