How do you compute the volume of a partially filled cylinder on its side by knowing the height of the fluid on a vertical diameter measuring stick?
Solution :
Since, we can measure the height of fluid. Let it be h.
So height of cylinder is double the height i.e. 2h because cylinder is partially filled.
Also, we can also measure diameter. Let it be d.
Now, we know, radius is haft the length of diameter.
So, r = d/2.
Volume of cylinder is given by :
[tex]V =\pi \times radius^2 \times height \\\\V =\pi\times (\dfrac{d}{2})^2 \times 2h\\\\V = \dfrac{ \pi d^2 h}{2}[/tex]
Hence, this is the required solution.

Rocco went bowling with $40 to spend. He rented shoes for $7 and paid $6 for each game. What was the greatest number of games Rocco could have played?
Answer: 5
Step-by-step explanation:
Let x = the number of games Rocco played.
Rent of shoes = $7
Charge per game = $6
Total Charge = 6x+7
As per given,
[tex]6x+7 \leq40\\\\\Rightarrow\ 6x\leq 40-7\\\\\Rightarrow\ 6x\leq33\\\\\Rightarrow\ x\leq\dfrac{33}{6}\\\\\Rightarrow\ x\leq5.5[/tex]
Hence, the greatest number of games Rocco could have played = 5

The width of a rectangle varies inversely with its length. If the width is 4 when the length is 18, find the width when the length is 8
Answer:9
Step-by-step explanation:
Based on the calculations, the new width of this rectangle is equal to 9 units.
How to calculate the new width?Mathematically, the inverse relationship between width (w) and length (l) is given by:
w α 1/l
w = k/l
k = wl
Given the following data:
Width A = 4 units.Length A = 18 units.Substituting the given parameters into the formula, we have;
k = 4 × 18
k = 72.
Now, we can determine new width:
w = k/l
w = 72/8
Width, w = 9 units.

what would be the solution for x inequality 47-4x<7
Answer:
x>10
Step-by-step explanation:
Think of this as an equation:
47-4x<7
Add 4x to both sides:
47<7+4x
Subtract 7 from both sides:
40<4x
Divide both sides by 4:
x>10
Answer:
x > 10
Step-by-step explanation:
Given
47 - 4x < 7 ( subtract 47 from both sides )
- 4x < - 40
Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity.
x > 10

Peter and Flopsy are Mairies pet bunnies. Peter is one year older than four times Flopsy's age. The sum of their ages is 19. How old is each bunny ?
Answer: See explanation
Step-by-step explanation:
Let Flopsy's age be represented by x.
Therefore, since Peter is one year older than four times Flopsy's age. Peter's age will be:
= (4 × x) + 1
= 4x + 1
We are further told that the sum of their ages is 19. This will be:
x + 4x + 1 = 19
5x + 1 = 19
5x = 19 - 1
5x = 18
x = 18/5
x = 3.6 years
Flopsy's age = 3.6 years
y = 4x + 1
= 4(3.6) + 1
= 14.4 + 1
= 15.4 years
Peter's age = 15.4 years

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
-4p + 9 = -5
Step 2: Solve for p
Subtract 9 on both sides: -4p = -14Divide -4 on both sides: p = 7/2Step 3: Check
Plug in p into the original equation to verify it's a solution.
Substitute in p: -4(7/2) + 9 = -5Multiply: -14 + 9 = -5Add: -5 = -5Here we see that -5 does indeed equal -5.
∴ p = 7/2 is the solution to the equation.
Answer:
[tex] - 4p + 9 = - 5 \\ - 4p = - 14 \\ p = \frac{ - 14}{ - 4} \\ p = \frac{7}{2} \\ \boxed{ p = 3.5}[/tex]

Use the Distributive Property to solve the equation
5x - 3(x-3)=-6+6x-5
Will give out brainlist only if you get it right
9514 1404 393
Answer:
x = 5
Step-by-step explanation:
The distributive property lets us eliminate parentheses on the left.
5x -3x +9 = -6 +6x -5
Collecting terms, we get ...
2x +9 = 6x -11
Subtracting 2x leaves ...
9 = 4x -11
Adding 11 gives ...
20 = 4x
Finally, dividing by 4, we have the solution ...
5 = x
