Hi,
Formula for ball volume (considered a sphera) is:
![V=\dfrac{4\pi\cdot r^3}3=\dfrac{4\pi\cdot 15^3}3=\dfrac{42,390}3=14,130\ in^3.](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%5Cpi%5Ccdot%20r%5E3%7D3%3D%5Cdfrac%7B4%5Cpi%5Ccdot%2015%5E3%7D3%3D%5Cdfrac%7B42%2C390%7D3%3D14%2C130%5C%20in%5E3.)

Answer:
{
}
The number line is attached.
Step-by-step explanation:
By definition Set-builder notation is a mathematical shorthand used to provide specific details about a set.
In this case, you have the following interval:
![(-6,2]](https://tex.z-dn.net/?f=%28-6%2C2%5D)
You can obsseve that the left hand contains a parentheses, which means that -6 it is not included, then:
![-6](https://tex.z-dn.net/?f=-6%3C)
The right hand contains a bracket, which means that 2 is included:
![\leq 2](https://tex.z-dn.net/?f=%5Cleq%202)
The inequality is:
![-6](https://tex.z-dn.net/?f=-6%3Cx%5Cleq%202)
Therefore, in Set-builder notation this is:
{
}
Observe the number line attached. Since -6 is not included, you must use an unfilled circle. Since 2 is included, you must use a filled circle.
Answer:
6 tablespoons of baking soda
Step-by-step explanation:
There are 8 fluid ounces in 1 cup and shes going to use half a cup so that means shes going to use 4 fluid ounces of vinegar. To find how much baking soda she is going to use, we are going to multiply.
1.5 * 4 = 6
Best of Luck!
Answer:
The length of BC = 28 units
Step-by-step explanation:
* In triangle ABC
∵ Angles B and C are congruent
∴ m∠B = m∠C
* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length
∴ AB = AC
∵ AB = 4x - 7
∵ AC = 2x + 7
∴ 4x - 7 = 2x + 7 ⇒ collect like terms
∴ 4x - 2x = 7 + 7
∴ 2x = 14 ⇒ divide both sides by 2
∴ x = 14 ÷ 2 = 7
* Now we can find the length of BC
∵ The length of BC = 4x ⇒ substitute the value of x
∴ The length of BC = 4 × 7 = 28 units
