250.6 is your number
The "6" in .6 right after the decimal is the tenths place
So right after the tenths place is the hundredths place
But as you can see in 250.6, there is no hundredths place you can see so it is 0
250.60 is the same as 250.6
So 250.6 is already rounded to the nearest hundredths
Answer:
y=-1
Step-by-step explanation:
use point slope formula y-y₁=m(x-x₁)
find m which is slope -1--1/-4--1= 0/-3= 0
plug in the equation and use the first point
y--1=0(x--1)
y=-1
Answer:
First you should determine in how many minutes she walks just one mile. For this, you just divide 90:6 and you get 1 mile in 15 minutes. After this, you just divide 60:15 and so you get 4 miles.
The frequency of the emitted radio waves is:

The energy of a photon is given by:

where h is the Planck constant and f is the photon frequency. Using the frequency given by the problem, we can find the energy of each photon of this radiation:
Answer:
x = -4
Step-by-step explanation:
You kind of didn't capture the directions in your image, but it looks like maybe they want you to write the equation of the line.
So this is what you need to know: the equation of a vertical (up and down) line is
x = anumber
For future reference on the next question, the equation of a horizontal (flat, left and right) line is
y = anumber
For this question, though, it's vertical.
so x = -4
You can check by picking as many points as you like and find that they ALL have -4 as the x value. Also, you will find the slope formula gives you an answer that is undefined. That's why you can't write an equation using y=mx+b. Hope this helps! I can edit if the question is something wildly different for real.
