Edge length of the side of a cube = 5 inches
Then
Volume of the cube = (side)^3
= (5)^3
= 125 inches ^3
So the volume of the actual cube is 125 inches^3
Now after the side lengths are triple, then
New edge length of each side = 3 * 5 inches
= 15 inches
Then
New volume of the cube = (New side)^3
= (15)^3
= 3375 inches^3
Then the volume of the new cube is 3375 inches^3
So
The number of times the volume of the new cube is greater = 3375/125
= 27
<span>So the volume of the new cube is 27 times greater than the old cube.</span>
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 8 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, then
y = - 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - 3x + 5 ← equation of line
Answer:
y≤-3
Step-by-step explanation:
5 - 8y ≥ 11 -6y There isn't anything to distribute
So bring the variable to one side of the inequality
In this case add 6 to both side
5 -2y ≥ 11
now subtract 5 in both side
-2y ≥ 6
now you have to divide by -2 so you have have to flip the sign since you are dividing by a negative number
y≤-3
