Answer:
Y= 3b
Step-by-step explanation:
Write an equation describing the relationship of the given variables. y varies inversely as the cube root of x and when x=125, y=8.
Answer:
y = 40 / x^1/3
Step-by-step explanation:
Given that :
y α x^1/3
y = k * 1 / x^1/3
y = k / x^1/3
When x = 125 ; y = 8
8 = k / 125^1/3
Cube root of 125 = 5
8 = k / 5
8 * 5 = k ; k = 40
Hence, expression becomes :
y = 40 / x^1/3
y α k/∛x is the relationship of the variables x and y whose values are 125 and 8.
What is Equation?Two or more expressions connected with an equal sign is called Equation.
The relationship of the given variables. y varies inversely as the cube root of x.
By given data we can write as
y α k/∛x
The cube root of 125 is 5.
y α k/∛125
y α k/5
8=k/5
k=40
Hence y α 40/∛x is the relationship of the variables x and y whose values are 125 and 8.

Richard Hoskins was the leader of a 4-H club with 27 children. When he divided the club into groups of 5 to play a game, how many groups did he have? How many extra children were there?
Answer:
5 groups
2 extra children
Step-by-step explanation:
The computation of a number of groups and number of extra children is shown below:
Given that
There is 27 children
And, this group would be divided into group 5
So,
As we know that 25 is easily divided by 5
So there are 5 groups
And, the extra children is
= 27 - 25

The diagram shows a 3 cm x 5 cm x 4 cm cuboid
Answer:
a) The length of segment AC is approximately 5.83 centimeters.
b) The angle ACD is approximately 34.5º.
Step-by-step explanation:
a) Since [tex]AB \perp BC[/tex], the length of segment [tex]AC[/tex] is determined by Pythagorean Theorem, that is:
[tex]AC = \sqrt{(5\,cm)^{2}+(3\,cm)^{2}}[/tex]
[tex]AC \approx 5.831\,cm[/tex]
The length of segment AC is approximately 5.831 centimeters.
b) Since [tex]AB \perp BC \perp AD[/tex], the length of segment [tex]AD[/tex] is determined by this Pythagorean identity:
[tex]AD = \sqrt{(3\,cm)^{2}+(5\,cm)^{2}+(4\,cm)^{2}}[/tex]
[tex]AD \approx 7.071\,cm[/tex]
The angle ACD is determined by the following trigonometric expression:
[tex]\cos C = \frac{AC}{CD}[/tex]
[tex]\cos C = \frac{5.831\,cm}{7.071\,cm}[/tex]
[tex]\cos C = 0.825[/tex]
[tex]C = \cos^{-1} 0.825[/tex]
[tex]C \approx 34.448^{\circ}[/tex]
The angle ACD is approximately 34.448º.

Their Ratio
Step-by-step explanation:
You switched the numbers 2 and 3 btw
[tex]\boldsymbol{\left ( 2 \right )}[/tex] their ratio
A ratio indicates how many times one number contains another.
Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.
When two variables are proportional, [tex]\boldsymbol{\left ( 2 \right )}[/tex] their ratio is constant.

y= -3x + 1 and y= x - 3
Answer:
x= 1
y= -2
Step-by-step explanation:
equation (1): y= -3x+1
equation (2): y=x-3
solve the system of equations by substitution:
step1: sub ( x-3 ) for y in equation 1:
y = -3x+1
x-3 = -3x+1
step2: simplify the equation to get x:
(add 3 for both sides)
x = -3x+4
(add 3x for both sides)
4x = 4
(divide 4 from both sides)
x = 1
step3: sub the value of x (x=1) in equation 2:
y = x-3
y = 1-3
step4: solve the equation to get y:
y = -2
What is the length of line segment HJ?
Answer:
b = 5√3 (units)
Step-by-step explanation:
To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.
In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.
a^2+b^2 = c^2 (pythagorean therorm)
5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)
25+b^2 = 100 (square the numbers)
b^2 = 75 (subtract 25 from both sides)
b = √75
b = √25 * √3 (factor out√75)
b = 5 * √3 (find square root of√25)
b = 5√3
