Answer:

r = [tex]\sqrt[3]{\frac{3v}{4\pi } }[/tex]

Step-by-step explanation:

Given

v = [tex]\frac{4}{3}[/tex] πr³ ( multiply both sides by 3 to clear the fraction )

3v = 4πr³ ( isolate r³ by dividing both sides by 4π )

[tex]\frac{3v}{4\pi }[/tex] = r³ ( take the cube root of both sides )

[tex]\sqrt[3]{\frac{3v}{4\pi } }[/tex] = r

b. 311,875,200
c. 154,440
d. 6,497,400

Answers

Answer:

Step-by-step explanation:

The possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .

What is permutation?

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol [tex]P_{r} ^{n}[/tex] is used to denote the number of permutations of n distinct objects, taken r at a time.

Formula of permutation

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]

According to the question

Remove all of the hearts from a normal deck of cards.

i.e,

Total normal deck of cards = 52

On Removing hearts cards(n) = 13  

Now, with this new hearts-only deck, how many possible five-card hands can you draw .

Card to draw (r)= 5

Applying formula of  permutation

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]

n = 13

r = 5

Substituting the values

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13!)}{(13-5)!}[/tex]

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13*12*11*10*9*8!)}{(8)!}[/tex]

[tex]P_{r} ^{n}[/tex] = 15,4440

Hence, the possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .

A barn of wheat on the first feild makes up 37 1/2 thousands of pounds per acre,and on the second1 2/15 times as much per acer. How much more wheat was gathered from the second feild than from the first

Answers

Answer:

250 pounds

Step-by-step explanation:

Since the area of the first field is 16 acres and that of the second field is 1¹/₄ times that of the first field, the are of the second field is thus 16 × 1¹/₄ acres = 16 × 5/4 = 4 × 5 = 20 acres.

Also, A barn of wheat on the first field makes up 37 ¹/₂ thousands of pounds per acre, and on the second 1 ²/₁₅ times as much per acer. So, the amount of wheat per acre of the second field is thus 37 ¹/₂ ×  1 ²/₁₅ thousand pounds per acre = 75/2 × 17/15 = 5/2 × 17 = 85/2 = 42 ¹/₂ thousand pounds per acre.

The amount of wheat gathered on the first field is thus 16 acres × 37 ¹/₂ thousands of pounds per acre = 16 × 75/2 = 8 × 75 = 600 pounds

The amount of wheat gathered on the first field is thus 20 acres × 42 ¹/₂ thousands of pounds per acre = 20 × 85/2 = 10 × 85 = 850 pounds

So, the amount of wheat gathered on the second field more than the first is thus 850 pounds - 600 pounds = 250 pounds.

What is molecular structure?

The term "molecular structure" refers to the structure of a molecule that merely consists of the arrangement of its atoms.

A chemical compound is a material made of several similar molecules that are linked together by chemical bonds and are made up of atoms from various elements.

Chemical compounds cannot be created when two atoms of the same element are bound together since this would need the presence of two distinct elements.

In diagram C it is obtained that atoms are combined to form the compound.

The finest example of two components combining to make a compound is in Option C.

Hence, option C is correct.

An NBA Basketball court is a rectangle that is 94 feet long and 50 feet wide. What is the area of the court? What is the perimeter of the court?
Area= Sq.feet
Perimeter= Feet

Answers

Answer:Area = 4700 feet squared

Perimeter= 288 feet

Step-by-step explanation:

Length = 94 feet

Width = 50 feet

Area = Length × Width

= 94 feet × 50 feet

= 4700 feet squared

Perimeter = 2(Length + Width)

= 2(94 feet + 50 feet)

= 2(144 feet)

= 288 feet

Find the center and radius of the circle given by this equation: x^2 - 10x + y^2 + 6y - 30 = 0

Answers

Answer:

center=(5,-3)

radius = 2 unit

Step-by-step explanation:

         Center with the equation x² - 10x + y² + 6y - 30 = 0 is (5, -3) and the radius is 8 units.

Circle with the given center and radius: Equation of a circle with the center (h, k) and radius 'r' is given by,

         (x - h)² + (y - k)² = r²

         Here, Center of the circle → (h, k)

                    Radius of the circle → r units

Given equation of the circle in the question is,

x² - 10x + y² + 6y - 30 = 0

Convert this equation to the standard equation of the circle.

x² - 2(5x) + y² + 2(3y) - 30 = 0

[x² - 2(5y) + 5²] - 5² + [y² + 2(3y) + 3²] - 3² = 30

(x - 5)² - 25 + (y + 3)² - 9 = 30

(x- 5)² + (y + 3)² = 64

(x- 5)² + (y + 3)² = 8²

     Therefore, center of the circle is (5, -3) and radius of the circle is 8 units.

2 > -2 this is because 2 is a positive and -2 is a negative. Negative numbers are numbers that are behind zero. Whereas positive numbers are in front of zero.

-2 > -5 normally 5 would be greater than 2. However, negative numbers are backwards. Picture a number line, where positive numbers are going forward...negative numbers are going backwards.
