Answer:
84 in
Step-by-step explanation:
The Pythagorean theorem is used to find the length 'b'.
b^2 +12^2 = 37^2
b = √(37^2 -12^2) = √1225 = 35
Then the perimeter is the sum of side lengths:
P = a + b + c = 12 + 35 + 37
P = 84 . . . inches
Answer:
71%
Step-by-step explanation:
I think the easiest way to think of this is to pretend that there are a total of 100 students at the high school, so that means the amount of people who work part time is 45% of 100 = 45 people. If 60% of those students love math, you do 0.6 * 45 = 27 people.
Next, 80% of the students who do not have a part time job (100 - 45 = 55) love math, so 0.8 * 55 = 44 people.
44 + 27 = 71, so the percent is 71/100 = 71%.
let me know if any part of that doesn't make sense
I can see that 2 is a root but not 1? So I tried -1 by substitution and that works.
So to work out the 3rd root we just use the sum and product of roots theorem.
We have the sum of the roots = 11/7 and from there the third root is 4/7
Do you want me to give an example of (x,y)?
<h3>The value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889</h3>
<em><u>Solution:</u></em>
<em><u>Given that:</u></em>
We have to find the value of expression
We know that,
Therefore,
We know that,
Similarly,
Thus value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889
