Use pythagorean’s theorem
as you can see it’s a right isosceles triangle
so your equation is adapted to this:
p^2 + p^2=44^2
add like terms and simplify
2p^2=1936
divide by 2
p^2=968
square root
p= √968
simplify
p=22√2
the answer would be your second option
Answer:
1. x= - 20/13
2. 7x-21
Step-by-step explanation:
Answer:
5(8-x)
Step-by-step explanation:
Fact using the GCF (Greatest Common Factor) of 40 and 5
Factors of 5:
1,5
Factors of 40:
1,2,4,5,8,10,20,40
The greatest factor they both have is 5
Factor by distributing out a 5
40-5x
5(8-x)
There are 7 marbles, including 3 green ones, so at the start, there is a 3/7 chance of getting a green marble.
Assuming you did get a green one, there are now 6 marbles left, with 2 blue marbles, so there is a 2/6 chance of taking a blue marble.
Given that both have to happen, you must multiply each probability, hence the total probability is 3/7 x 2/6, or a 1/7 chance.
Hope this helped
