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.

Step-by-step explanation:
m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.
m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.
Step-by-step explanation:
148 + x = 180
x = 180 - 148
x = 32
Find m<CAB basically means find the measure of the angle of A ( m<A )
m<B + m<A + x = 180
85 + m<A + 32 = 180
117 + m<A = 180
m<A = 180 - 117
m< A = 63, so m<CAB = 63
And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.
So m<BCA = 32

Find the value of (1/5)⁻² + (1/2)⁻³ + (1/4)⁻¹
Answer:
Answer = 37
Step-by-step explanation:
= (5)² + (2)³ + (4)¹
= 25 + 8 + 4
= 37 Answer
Answer: The answer is 37
Step-by-step explanation:
Step 1: Use Negative Power Rule: x^-a=1/x^a. So 1/(1/5)^2+(1/2)^-3+(1/4)^-1
Step 2: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/5^2+(1/2)^-3+(1/4)^-1
Step 3: Simplify 5^2 to 25. So 1/1/25+(1/2)^-3+(1/4)^-1
Step 4: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/(1/2)^3+(1/4)^-1
Step 5: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/25+1/1/2^3+(1/4)^-1
Step 6: Simplify 2^3 to 8. So 1/1/25+1/1/8+(1/4)^-1
Step 7: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/1/8+1/1/4
Step 8: Invert and multiply. 25+1/1/8+1/1/4
Step 9: Invert and multiply. 25+8+1/1/4
Step 10: Invert and multiply. 25+8+4
Step 11: Simplify 25+8 to 33. So 33+4
Step 12: Simplify. So the answer is 37
The area and length of a rectangle are given below. Find the w, the width.
Answer:
1.5
Step-by-step explanation:
yaaa
This is the same as 1.5 feet and it is equivalent to the improper fraction 3/2.
============================================================
Explanation:
Let's convert the given mixed numbers into improper fractions.
A = 5 & 1/3 = 5 + 1/3 = 15/3 + 1/3 = (15+1)/3 = 16/3
L = 3 & 5/9 = 3 + 5/9 = 27/9 + 5/9 = (27+5)/9 = 32/9
So the area and length are 16/3 and 32/9 respectively.
-------------------
Let's solve for the width W
area = length*width
A = L*W
16/3 = (32/9)*W
9*(16/3) = 9*(32/9)*W ..... multiplying both sides by 9
48 = 32W
32W = 48
32W/32 = 48/32 ....... dividing both sides by 32
W = 48/32
W = (32+16)/32
W = 32/32 + 16/32
W = 1 + 1/2
W = 1 & 1/2 feet is the width
This is equivalent to 3/2 since 48/32 = 3/2
It's also equivalent to 1.5 because 3/2 = 1.5
What is the area of the figure, use 3.14 for π

Factor the following polynomial completely. -0.8x2 - 6.4x + 7.2
Answer:
-0.8(x + 9)(x - 1)
Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:
= -0.8(x + 9)(x - 1)

Step-by-step explanation:
Given - A group of friends went to the movies, and the three guys each
bought two tickets (t), a popcorn (p) and two drinks (d) for
themselves and their dates.
To find - After distributing, we can represent this situation with the
expression.
Proof -
As given , three guys each bought two tickets (t), a popcorn (p) and two drinks (d) for themselves and their dates.
Let ticket = t
popcorn = p
drink = d ,
Then,
The expression becomes -
3[2t + p + 2d ] = 6t + 3p + 6d
∴ we get
We can represent this situation with the expression - 6t + 3p + 6d
