Answer:
60 feet
Step-by-step explanation:
The length of the diagonal can be found from the Pythagorean theorem.
d = √(15² +20²) = √(225 +400) = √625
d = 25
Then the distance Haley walks is ...
20 ft + 15 ft + 25 ft = 60 ft
Answer:
P(A∩B) = 0.522
Step-by-step explanation:
Let's call A the event that a puppy is adopted and B the probability that a puppy live 7 or more years
So, the probability P(A∩B) that a randomly selected puppy in the shelter will get adopted and live 7 or more years is:
P(A∩B) = P(A)*P(B/A)
Because A and B are not independents.
Then, the probability P(A) that a puppy is adopted is 58% and the probability P(B/A) that a puppy live 7 or more years given that the puppy is adopted is 90%.
Finally, replacing the values, we get:
P(A∩B) = 0.58*0.9 = 0.522
It means that the 52.2% of the puppies are adopted and live 7 or more years.

Answer:
The discriminant is 0.
Step-by-step explanation:
we know that
In a quadratic equation of the form
The discriminant is equal to
If D=0 -----> The equation has only one real solution
If D>0 ----> The equation has two real solutions
If D<0 ----> The equation has complex solutions
In this problem
If the equation has only one intercept (x=6)
then
The equation has only one real solution
therefore
The discriminant is 0.
Answer:
2x - 4
Step-by-step explanation:
We will have to use one variable.
Let's use "x" and call that number of shots taken by "Kyle"
So, we say:
Kyle takes "x" shots
It is told that Ben takes 4 fewer shots than Kyle, so:
Ben takes "x - 4"
So, the amount of shots both take is the sum of both shown above. So,
Total Shot = x + x - 4
Simplifying:
<u>2x - 4</u>
