In this question, AE is the length of half of one diagonal in the rectangle. DB is the length of the other diagonal. 2(4x-12) would be the total length of the other diagonal, AC. You can set 2(4x-12) equal to 7x-18 and solve for x.
2(4x-12)=7x-18
8x-24=7x-18
x-24=-18
x=6
Answer:
300 SUVs were sold.
210 Passenger cars were sold.
Step-by-step explanation:
Let S denote the amount of SUVs sold and let P denote the amount of passenger cars sold.
The total amount of vehicles sold was 510, so:
90 more SUVs were sold than passenger cars. In other words:
We know have a system of equations. We can solve it buy substituting the second equation into the first. Thus:
Combine like terms:
Subtract 90 from both sides:
Divide both sides by 2:
So, the 210 passenger cars were sold.
This means that 210+90=300 SUVs were sold.
And we're done!
Answer:
Step-by-step explanation:
Thinking process:
Let the total set be the combination of all the sets as shown
It means that total items = 7 + 14 + 7 + 2
= 30
But the total number of the subsets = 5 + 7+ 2
= 14
Therefore the probability =
=
=

What's the height of a cylinder formula?</h3>
There are five basic equations which completely describe the cylinder with given radius r and height h:
- Volume of a cylinder: V = π * r² * h,
- Base surface area of a cylinder: A_b = 2 * π * r²,
- Lateral surface area of a cylinder: A_l = 2 * π * r * h,
- Total surface area of a cylinder: A = A_b + A_l,
- Longest diagonal of a cylinder: d² = 4 * r² + h².
Sometimes, however, we have a different set of parameters. With this height of a cylinder calculator you can now quickly use ten various height of a cylinder formulas which can be derived directly from the above equations:
- Given radius and volume: h = V / (π * r²),
- Given radius and lateral area: h = A_l / (2 * π * r),
- Given radius and total area: h = (A - 2 * π * r²) / (2 * π * r),
- Given radius and longest diagonal: h = √(d² - 4 * r²),
- Given volume and base area: h = 2 * V / A_b,
- Given volume and lateral area: h = A_l² / (4 * π * V),
- Given base area and lateral area: h = √(A_l² / (2 * π * A_b)),
- Given base area and total area: h = (A - A_b) / √(2 * A_b * π),
- Given base area and diagonal: h = √(d² - 2 * A_b / π),
- Given lateral area and total area: h = A_l / √(2 * π * (A - A_l)).
