Answer:
Step-by-step explanation:
The formula one would use for finding the volume of a rectangular prism is as follows:
- Volume = length × width × height ,
With this in mind, let's plug in the given variables in the question for this formula.
?
- We don't know the height, but that's just fine. We will plug in all our values and isolate
.
- I'm leaving in units just because I want to show that units aren't just for show. They can be used when in doubt of how to go about your math.
- Notice, that the units on the left side cancel out, leaving only the unit
left next to the solution. In the same way, the units on the right side cancel out too, leaving only , height.
If involving units only confuses you, like it does for me, you can remove them like so, you just need to know what units your solution uses instead of being able to come to the proper units by using math.
The last one is no solutions and the first on is <span>infinitely many solutions
and the second one is one solution. I am pretty sure! Hope this helps!</span>
Answer:
31
Step-by-step explanation:
Answer:
y = -x +6
Step-by-step explanation:
The 2-point form of the equation for a line through points (x1, y1) and (x2, y2) is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
For your given points, this is ...
y = (1-4)/(5-2)(x -2) +4 . . . . with given points filled in
y = -1(x -2) +4 . . . . . . . . . . . simplify a bit
y = -x + 6 . . . . . . . . . . . . . . simplify to slope-intercept form
Answer:
200 students
Step-by-step explanation:
From the question;
- Total number of students = 1,000
- % percentage of students that speak Spanish= 20%
Required to determine the number of students that speak Spanish;
We are going to use;
- Number of students that speak Spanish = % of student that speak Spanish × Total students
Therefore, the number of students that speak Spanish is 200
