Answer:
2.5h = 150 min.
Step-by-step explanation:
An hour is 60 minutes.
A half an hour is 30 minutes.
Two hours = 1 hour + 1 hour = 60 minutes + 60 minutes = 120 minutes
2.5 hours = 2 hours + 1/2 hour = 120 minutes + 30 minutes = 150 minutes
2.5h = 150 min.
Hope this helps.
Answer:
It is an imaginary number.
Step-by-step explanation:
The square root of negative one is "i," the imaginary number. This concept is immensely useful in mathematics, as it allows for there to be square roots of negative numbers, which is otherwise not possible using only real numbers.
Any number that includes a negative square root is called an imaginary number. For example, the square root of -9 equals 3i, an imaginary number. When an imaginary number and a real number are combined, for example 2 + 3i, this is called a complex number. Complex numbers have many real world applications, including manipulating sound waves and calculating electrical currents.

Answer: Choice F) 1</h3>
=============================================
Explanation:
x^2+8x+7 factors to (x+1)(x+7)
x^2+4x-21 factors to (x-3)(x+7)
Therefore, the numerator (x^2+8x+7)(x-3) updates to (x+1)(x+7)(x-3)
The denominator (x^2+4x-21)(x+1) updates to (x-3)(x+7)(x+1)
We have three pairs of terms that will cancel between the numerator and denominator. The (x+1) terms pair up and cancel out, so do the (x+7) terms and also the (x-3) terms as well. Everything cancels out. The only thing left is 1 because x/x = 1 where x is nonzero. We can have a more complicated expression replace x to get the same basic idea. This is what I mean by "canceling".
Answer:
r = 3
Step-by-step explanation:
225 divided by 25 is 9 which is diameter
radius is half of the diameter which is 3
to find the radius you the formula of how to the volume of a cylinder then you flip it around.

A sum means that two numbers are added together. A square means that a number is raised to the second power.
The sum of a number c and its square can be written with this algebraic expression:
