12=T+3
Explain your answer
Thanks For the Help:)

Answers

Answer:

1.) z = -1

2.) z = -5

3.) t = 9

Step-by-step explanation:

z + (-7) = -8

=> add 7 to both sides

z = -1

13 = z + 18

=> subtract 18 from both sides

-5 = z

12 = t + 3

=> subtract 3 from both sides

9 = t

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 ft.
hl
Which equation gives the volume of the sphere?
V-011)
2
​

Answers

Answer:

length times width times height

Step-by-step explanation:

The equation for the volume of the sphere is:

V(sphere) = (4/3)πr³

What is a cylinder?

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

here,

We have,

If a sphere and a cylinder have the same radius and height, the volume of the cylinder is given by:

V(cylinder) = πr²h

where "r" is the radius of the cylinder, and "h" is the height of the cylinder.

If we know that the volume of the cylinder is 11 ft³, then we can write:

11 = πr²h

We can solve this equation for "h" to get:

h = 11 / (πr²)

Now, the volume of a sphere with radius "r" is given by:

V(sphere) = (4/3)πr³

Substituting the expression for "h" in terms of "r" into the volume formula for the cylinder, we get:

11 = πr²(11 / (πr²))

Simplifying this equation, we get:

11 = 11

This is an identity, which means that it is true for all values of "r".

Therefore, we can substitute any value of "r" into the formula for the volume of the sphere to get the volume of the sphere with the same radius as the cylinder.

Using the formula for the volume of a sphere, we get:

V(sphere) = (4/3)πr³

Thus,

The equation for the volume of the sphere is:

V(sphere) = (4/3)πr³

Name the additive identity of (-10+4i)

Answers

An additive identity for i, denoted e, is an element in i such that for any element i in i, e + i = i = i + e. Example: The formula is i + 0 = i = 0 + i.

The additive identity of (-10+4i) is (0+0i).

What is additive identity?

Additive identity property states that when a number is added to zero will give the same number in result . “Zero” is called the identity element, If we add any complex number with zero, the resulting number will be the same complex number. It doesn't change the number and keeps its identity.

For the given situation,

The complex number is (-10+4i)

The general form of complex number is a+bi. The additive identity for complex number is 0+0i.

⇒ [tex](-10+4i)+(0+0i)=(-10+4i)[/tex]

Hence we can conclude that (0+0i) is the additive identity of (-10+4i).

Timothy is sorting his building blocks into 8 bins. Each bin can hold 286 blocks. He has already put 74 blocks in the bins. How many more blocks does Timothy need to sort?

Answers

Answer: 2214 blocks

Step-by-step explanation:

From the question, we are told that Timothy is sorting his building blocks into 8 bins and that each bin can hold 286 blocks. Therefore, the total blocks that the bins would hold would be:

= 286 × 8

= 2288 blocks.

We are further told that he has already put 74 blocks in the bins. The number of remaining blocks that Timothy need to sort would be:

= 2288 - 74

= 2214 blocks

The Statue of Liberty stands as perhaps the most iconic symbol of our nations largely immigrant past and its European heritage in particular.Under the watchful gaze of this imposing monument, lives converged. Between 1892 and 1954, over 12 million immigrants passed through the processing facility on Ellis Island. Many of those people left homes across Europeparticularly England, Ireland, the German and Russian empires, and Scandinavian countriesto escape famine, political and economic oppression, or in search for greater opportunities in America. Upon crossing Americas shores, European immigrants spread across the North American continent, altering its physical and cultural landscape along the way. These experiences are often told through the treasured European American narrative of the melting potwhere diverse groups traveled to a New World, where they peopled a nation and forged a uniquely American identity. However, these immigrants arrived on a continent already populated by indigenous nations who possessed their own complex political, economic, and cultural systems. The ensuing encounters between these diverse groups serve as some of the foundational moments in American history.
