3/32 pound of cheesecake
3. (5/12) / (1/5)
4. 1 3/5
Step-by-step explanation:
1.
12 = 3/5
Multiply both sides by 5
60 = 3
Divide by 3
20 = 1
In 1 minute we can scan 20 pages.
2. 4 = 3/8
Divide by 4
1 = 3/32
3. (5/12)/(1/5)
4. 10/ 2.5 = 4
2/5 * 4 = 8/5
1 3/5

the area of a base of a cylindrical water tank is 12π square feet. the volume of water in the tank is dependent on the height of the water (h) and is represented by the function V(h) = 12π h
part a - find V to the power of -1 (h)
part b - what will the height of the water be when the volume reacher 420π cubic feet
Answer:
Step-by-step explanation:
V^－1(h)is find inverse function=h / 12π
V=12πh=420π
h=420π/12π=35 feet
The inverse of the function V(h) is V⁻¹(h) = h / (12π). And the height of the water is 35 feet.
What is the volume of a right circular cylinder?Let r be the radius and h be the height of the cylinder. Then the volume of the cylinder will be given as,
V = π r²h cubic units
A cylindrical water tank's base measures 12π square feet. The volume of water in the tank is proportional to its height (h) and is represented by the function V(h) = 12π h.
The inverse of the function V(h) is given as,
h = 12π V⁻¹(h)
V⁻¹(h) = h / (12π)
If the volume is 420π cubic feet. Then the height of the water is given as,
420π = 12π h
h = 420π / 12π
h = 35 feet
The inverse of the function V(h) is V⁻¹(h) = h / (12π). And the height of the water is 35 feet.

Gloria wants to make beef stroganoff for 12 people. Her recipe serves 8 people and calls for 4.5 pounds of ground beef. How much ground beef should Gloria purchase?
Answer:
6.75 pounds
Step-by-step explanation:
This question is of direct variation. We will use x as our answer. 8 is 2/3 of 12, so 4.5 should be 2/3 of x. We can now make an equation.
In order to solve the equation, we multiply both sides by the reciprocal of 2/3, which is 3/2.
* stands for multiplication
From solving our equation, we get 6.75. We can't forget the units, so the answer is 6.75 pounds.

(3x2)(−2x4) = 3(−2)x2∙4 = 6x8 can you find whats wrong with this problem
Answer:
the equal sign
Step-by-step explanation:
The final correct result is:[tex](3x^2)(-2x^4) = -6x^6[/tex]
Given that:
The expression: [tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]
The error is in the second step of the simplification:
[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} \\(3x^2)(-2x^4) = 6x^8[/tex]
[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]
The second step is incorrect. The correct rule for multiplying powers with the same base is to add the exponents, not multiply them.
Here, add the power of x is 2 and 4, that is,
2 + 4 = 6
And multiply the coefficient of x as:
The coefficient of x are 3 and (-2).
So, the multiplication as:
3 × (-2) = -6
The correct simplification should be:
[tex](3x^2)(-2x^4) = 3\times(-2) \times x^{2+4}\\(3x^2)(-2x^4) = -6x^6[/tex]
So, the multiplication as:
3 × (-2) = -6
So, the final correct result is:
[tex](3x^2)(-2x^4) = -6x^6[/tex]
Hence, the error occupied in second step.
