answer: 8
i added all the numbers and divided them by how much numbers there are
Answer: No
Step-by-step explanation:
To find out if it is a right triangle then use the formula a^2 + b^2 = c^2 where a and b are the legs which are the two small sides and c is the hypotenuse the longest side. Input the values for a, b, and c and solve.
a = 12
b = 16
c= 25
12^2 + 16^2 = 25^2
144 + 256 = 625
400 = 625
This means that it is not a right angle because 400 does not equal to 625.
Answer:
The number is 25
Step-by-step explanation:
we have
![x^{2} -10x=7](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-10x%3D7)
we know that
![10/2=5](https://tex.z-dn.net/?f=10%2F2%3D5)
so
Adds
both sides
![x^{2} -10x+5^{2}=7+5^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-10x%2B5%5E%7B2%7D%3D7%2B5%5E%7B2%7D)
![x^{2} -10x+25=7+25](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-10x%2B25%3D7%2B25)
![x^{2} -10x+25=32](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-10x%2B25%3D32)
Rewrite as perfect squares
![(x-5)^{2}=32](https://tex.z-dn.net/?f=%28x-5%29%5E%7B2%7D%3D32)
Answer:
L = 20
Step-by-step explanation:
Rearrange the equation in terms of P and w
L = (P - 2w)/2
Plug in your values for P and w
L = (52 - 2(6))/2
L = 40/2
L = 20
It has to go through two steps,
first: works in the morning at 50%
second : overheats rest of the day at 15%
Probability that it will work in the morning and overheats rest of the day is the product of the two probabilities, namely
Probability=0.50*0.15=0.075, or 7.5%.
