first thing to do is get up from your sit and go cry because that question is to hard
Answer:
I am not sure, but I think you would check for the side with the longest length(hypothenuse) and check if the formula of a^2+b^2=c^2(side with the longest length) satisfies it.
Answer:
Step-by-step explanation:
Set the two unknown numbers to X and Y.
X + Y = 22
2X = 10Y
Rewrite the second equation as: X = 5Y
Now use this in the first equation: 6Y=22
Y = 3.67 [3 2/3]
X = 18.33 [18 1/3]
---------------------------------------
3 2/3 + 18 1/3 = 22, and
2*(18 1/3) = 10*(3 2/3)
Answer:


Step-by-step explanation:
Lets call
the the still-air speed of the plane and
the speed of the wind. On the first part the speed of the plane relative to the ground will be
, and on the second part it will be
.
We know that the distance d=400 miles on the first and second parts are the same, so by the definition of velocity we will have:


Or:


Adding both equations:


Which for our values is:

If instead of adding, we substact, we would have:


Which for our values is:

Answer:
The probability that a student pick from this group at random either has blue or brown eyes is
P = 40/65 = 0.6154
P = 61.54%
Corrected question;
In a group of 65 students 10 have brown eyes and 30 have blue eyes. Find the Probability that a student pick from this group at random either has blue or brown eyes
Step-by-step explanation:
Given;
Total number of students = 65
Number of students with either blue or brown eyes;
= 10+30 = 40
The probability that a student pick from this group at random either has blue or brown eyes is
P = 40/65 = 0.6154
P = 61.54%
