Answer:

Step-by-step explanation:
The formula of a surface area of a cube:

The formula of a volume of a cube:

We have

Calculate the edge length (<em>a</em>).
<em>divide both sides by 6</em>

Calculate the volume of a cube:

Answer:
$800
Step-by-step explanation:

Answer:

Step-by-step explanation:
As you can observe in the image attached, the line that best fits passes through point B and C. That means we can use those point to find the slope of such line.

Where
and 

So, the slope of the line that best fits is -11, approximately.
Now, we use the point-slope formula to find the equation.

Therefore, the line that best fits is
approximately.
Remember, when we estimate a line for some data on a scatterplot, we are calculating an approximation, that's why we also said "approximately", because the line is an approximation where the majority of point meet.
Answer:
Step-by-step explanation:
Plug each value of x into the equation and solve for the corresponding y value.
When x = -1, y = (-1)²-2(-1) = 3
When x = 0, y = 0² - 2(0) = 0
You can finish from here.
Given:
A school is planning a 4th grade field trip. There are 157 students and 9 teachers in the 4th grade. Each bus holds 45 people.
Required:
To find the number of buses does the school need to make the field trip.
Final Answer:
There area total

166 people.
Let the number of bus be x.
Each bus holds 45 people, therefore

Final Answer:
4 buses need to make the field trip.
