38.94 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down
38.94
The number is 4, so we round down. 38.94 becomes 38.9
65.45 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down.
65.43
The number is 3, so we round down. 65.43 becomes 65.4
38.9+65.4= 104.3
If you were to estimate 38.94+65.43, we round the number to numbers that we can easily calculate in our head. 38.94+65.43 becomes 40+65
40+65=105
Answer:
it is 4.17
Step-by-step explanation:
i just know
Answer:
The dependent variables in most cases is output variable. That is a value that depends on some other input value and changes based on that input value.
Step-by-step explanation:
- In the question, it is given that a problem uses an output variable.
- It is required to explain how to find the output variable in a word problem that uses a linear function.
- In order to find the output variable in a world problem, for the dependent variable.
- That is a value that depends on some other input value and changes based on that input value.
- It cannot change independently. In these types of functions, this value is mostly marked as y or f(x).
Answer:
use y=mx+b format to find the y-intercept
Step-by-step explanation:
the y-intercept is b of course
the y-intercept is where the y meets a line
the equation will be _=_x+_
A piecewise function is a function that has different functions for different domains on the horizontal axis.
Normally, they are useful to describe the movement of objects. We can describe the acceleration or speed by using these functions.
Each function has its own domain in these functions.
Answer:
"domain"
For a piecewise function, the domain is broken into pieces, with a different rule defining the function for each piece.
