A cube has a volume of 125 cubic inches. What is the length of each edge?
Enter your answer in the box.
(Needs to be in inches)
Answers
The formula for the volume of a cube is V = a^3.
We know the volume is 125 cubic inches.
125 = a^3
Take the third square root
5 = a
The length of each edge is 5 inches
Answer:
So the length of the edge of a cube with a volume of 125 is 5 inches
Step-by-step explanation:
All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power.
So if we take the edge of the cube to be of length x, then:
Volume=x3
125=x3
5=x
Solve the equation. Check your solution.
Answers
Answer:
x = 5
Step-by-step explanation:
x^2/(x + 5) = 25/(x+5) Subtract the right side from both sides.
x^2/(x + 5) - 25/(x + 5) = 0
x^2 - 25
======= = 0
x + 5
(x + 5)(x - 5)
============= = 0
(x + 5)
Cancel x + 5 in the numerator and denominator.
x - 5 = 0
x = + 5
Does it check?
x^2/(x + 5) = 25/(x + 5)
x = 5
5^2/(10) = 25/10
25/10 = 25/10 Yes it checks.

Find the y-intercept and x-intercept of the line. 5x-8y=14
Answers
Answer:
x-intercept = 14/5
y-intercept = 7/4
Step-by-step explanation:
To find the value of an intercept (x/y) of an equation like this, simply set the other variable to 0 and divide both sides by the coefficient of the variable you're trying to find.
5(0)-8y=14
-8y=14
Y=-2
So y intercept= -2
When y=0
5x-8(0)=14
5x=14
X=5/14 or 0.36
So x-intercept = 5/14

what is the equation of a line parallel to y = -1/2x + 6 that passes through (-4, 1)
Answers
Answer:
y = -1/2x - 1
Step-by-step explanation:
A line that is parallel to another will have the same slope. All we need to do is find the new y-intercept. We can do that by using the slope intercept form equation [ y = mx + b ].
1 = -1/2(-4) + b
1 = 2 + b
-1 = b
Now we can input the information we know and solved for back into the formula.
y = -1/2x - 1

Side XY is of length 11b .
Side XZ is of length 2a+3b.
Side YZ is of length a The triangle is isosceles, with XY=XZ
The perimeter of the triangle is 91. Use algebra to find the values of a and b.
Answers
Answer:
a = 14, b = 3.5
Step-by-step explanation:
XZ = XY , then
2a + 3b = 11b ( subtract 3b from both sides )
2a = 8b ( divide both sides by 2 )
a = 4b
The perimeter is 91 , so
11b +2a + 3b + a = 91
14b + 3a = 91 ← substitute a = 4b
14b + 3(4b) = 91
14b + 12b = 91
26b = 91 ( divide both sides by 26 )
b = 3.5
and a = 4b = 4 × 3.5 = 14

What is the volume of this cylinder shown below?
Answers
Answer: 138.16 cubic feet (choice H)
This volume is approximate and occurs when you use pi = 3.14
==========================================================
Work Shown:
r = 2 ft = radius
h = 11 ft = height
V = volume of cylinder
V = pi*r^2*h
V = pi*2^2*11
V = pi*4*11
V = pi*44
V = 44pi .... exact volume in terms of pi
V = 44*3.14
V = 138.16 .... approximate volume and the final answer

The sum of the present ages of a son and his father is 60 years. Six years ago, father's
age was five times the age of the son. After 6 years, what will be son's age?
Answers
Answer:
15 years old
Step-by-step explanation:
The equation for their present ages is s+f=60. Six years ago would make it 54 and since the father's age six years ago was 5 times his son's the equation would be s+5s=54 (add the common terms) 6s=54. 54/6 is 9. So the son's age is 9, currently. In six years, the kid will be 15.
