The volume of a square pyramid is equal to:
Volume = a^2 (h/3)
In order for us to get the height, we need to substitute the values.
<span>Volume = a^2 (h/3)
</span>960 = 12^2 (h/3)
960 = 144h/3
960 = 48h
h = 20 in.
So the height is equal to 20 inches.
The answer is going to be x=28
Here is how I did it:
You first need to subtract it first
6x/7+15-8=31
6x/7+7=31
you have to find the common denominator
6x/7+7=31
6x/7+7*7/7=31
Multiply all the terms by the same value to eliminate fraction denominators
7(6x+49)/7=7*31
6x+49=7*31
Multiply the numbers
6x+49=7*31
6x+49=217
Subtract 49 from both sides
6x+49=217
-49 -49
Now theres 6x=168
Divide both sides
6x=168

x=28 is your answer
The equation of a line is y=-1/4x-7, (option 1)
<h3>
What is the equation of a line? </h3>
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.
<h3>
How do you find the equation of a line?</h3>
Write the equation in the form y = mx + b to find the slope m and the y-intercept. This will allow you to graph the equation using the slope and y-intercept.
Given:-
Equation of the line is y=4x+8
The point through which the line passes (-8,4).
here the slope of the line is m1=4
To find the perpendicular line we know the formula
m1*m2=-1
By putting the value of m1 we get m2= -1/4
By using the one-point formula of the line we have
=>(y-y1)=m2*(x-x1)
By putting the values of y1 and x1 we get
(y1,x1)=(-8,4)
=>(y+8)=-0.25*(x-4)
y+0.25x+7=0
Hence the desired equation of the line is y=-1/4x-7

Answer:
120
Step-by-step explanation:
the formula of a box is L x W x H
so since the length is 6 and the width is 4 and the height is 5 you multiply
6x4x5=120
