Volume of the sphere to the nearest cubic cm will be 803.84 cm^3

A sphere has a spherical, symmetrical form. It is a three-dimensional solid with equal distances between each surface point and the center. On the basis of its radius, it has a surface area and a volume. There are no faces, corners, or edges on it.

The collection of all points in three-dimensional Euclidean space that are separated by a certain amount of space, or "radius," is known as a sphere (the "center"). The diameter is equal to twice the radius, and antipodes are pairs of locations on the sphere that are on opposing sides of a diameter.

Volume of sphere[tex]=\frac{4}{3} \pi r^3[/tex]

As we have the value of radius = r=4 cm

We have the value of total scoops = 3 mm

So, by putting the value in the above expression of the volume of the sphere, we will get it as:

[tex]V =\frac{4}{3} \times 3.14(4)^3 \times 3 \\=3.14 \times 256 \\=803.84 \mathrm{~cm}^3[/tex]

Answer:

Equal

Step-by-step explanation:

Since all angles are the same

So the border lines should also be equal

The width of the tabletop is t feet when its length is 12 feet.

In contrast to width, which is used to describe how wide an object is, length simply states how long something is.

The term "width" is also used to refer to "breadth." It is the distance measured across a specific shape or object, such as a rectangle, whose lengths form right angles with the sides.

In contrast to the measurement of the area of the rectangle, which is a product of two units, the length and width. Length and width are two fundamental one-dimensional units. Today, a variety of length units are in use. The metre in SI units of measurement is the most fundamental of all.

Given that:

The length of a larger tabletop is 2 more than 2 times its width

l = 2(w) + 2

The length is 12

12 = 2(w) + 2

12 - 2 = 2w

10 = 2w

w = 10/2

w = 5

Thus, the width of the tabletop is t feet when its length is 12 feet.

As per the unitary method the number of students who attended the play is 280.

The unitary method is a mathematical method used to find the value of a single unit in a given set of values. In this case, we will be using it to find the number of student tickets sold at the local play.

Let's say that "x" represents the number of student tickets sold.

The cost of each student ticket is $6, so the total cost of student tickets is $6x. The total cost of adult tickets is $11y, where "y" represents the number of adult tickets sold. The total ticket sales for the play was $3,000, so we can write the equation:

$6x + $11y = $3,000

We already know the cost of student tickets and adult tickets, so we can substitute those values into the equation:

$6x + $11y = $3,000

$6x = $3,000 - $11y

Now we can divide both sides of the equation by $6 to find the value of x:

x = ($3,000 - $11y) / $6

Since the total ticket sales were $3,000 for 400 tickets, we can use that information to solve for y:

$3,000 = $6x + $11y

$3,000 = $6x + $11(400 - x)

Expanding the equation:

$3,000 = $6x + $4400 - $11x

Combining like terms:

$3,000 = $-5x + $4400

Adding $5x to both sides:

$3,000 + $5x = $4400

Subtracting $3,000 from both sides:

$5x = $4400 - $3,000

$5x = $1400

Dividing both sides by 5:

x = $1400 / $5

x = 280

So, 280 students attended the play.

The negative exponents in the denominator change it into positive exponents are 1/(2⁻³) = 8, 1/(2x⁻³) = (1/2)x³  and 4/(2(3⁻³)) = (4/2)×3³ = 54

If you have a fraction with a negative exponent in the denominator, you can change it into a positive exponent by reversing the fraction and taking the reciprocal.

For example, if you have the fraction 1/(x⁻²) you can change it to x² by flipping the fraction and taking reciprocal: 1/(x⁻²) = 1/(1/x²) = x²

Note that when you have a negative exponent in the denominator, it means that the variable is in the denominator and the reciprocal can be taken to move the variable to the numerator, as shown above.

Thus, we can solve the given questions as follow:

1/(2⁻³) = 2³ = 8

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin.

The coin is fair, thus the outcomes "heads" and "tails" are equally likely; the likelihood of "heads" is equal to the likelihood of "tails"; and because there are no other conceivable outcomes, the likelihood of either "heads" or "tails" is 1/2 (which is also an acceptable spelling).

The fraction of blue marble in the jar is [(1/2)x]/ (x+3) where x+3 is the total marbles.

This question involves basic arithmetic and fractions.

We know that a fraction means a part of a whole. It is of the form a/b where b is not equal to zero and a, b are numbers.

Now, here let the total number of marbles in the bar is x .

Then , the number of blue marbles is (1/2)x i.e. 1/2 of x.

Now, if three black marbles are added to the jar, the total number of marbles = x + 3.

So, fraction of blue marble in the jar = (no. of blue marble)/(no. of total members)

= [(1/2)x]/ (x+3).

A single ticket's estimated earnings are around -$0.9442, which indicates that a consumer may expect to lose approximately $0.9442 for each ticket purchased.

To find the expected winnings of a single ticket, we need to calculate the weighted average of the winnings based on the probabilities of winning each prize.

The probabilities of winning each prize are as follows:

1st prize: 1 winner out of 10,000 tickets sold (probability = 1/10,000 = 0.0001)

2nd prize: 3 winners out of 10,000 tickets sold (probability = 3/10,000 = 0.0003)

3rd prize: 5 winners out of 10,000 tickets sold (probability = 5/10,000 = 0.0005)

Consolation prize: 20 winners out of 10,000 tickets sold (probability = 20/10,000 = 0.0020)

No prize: (1 - (probability of winning any prize)) = 1 - (0.0001 + 0.0003 + 0.0005 + 0.0020) = 0.9971

Now, let's calculate the expected winnings:

Expected winnings = (Probability of 1st prize × $3000) + (Probability of 2nd prize × $1000) + (Probability of 3rd prize × $500) + (Probability of consolation prize × $100) + (Probability of no prize × -$2)

Expected winnings = (0.0001 × $3000) + (0.0003 × $1000) + (0.0005 × $500) + (0.0020 × $100) + (0.9971 × -$2)

The problem states that Eduardo had 4.5 cups of flour in a jar, and then opened a bag of flour and poured it in until the jar was full. The question is how much flour was in the bag to start? To solve this problem, we can use an inequality. Let x represent the amount of flour in the bag to start. The equation we can use is x + 4.5 ≥ 12, which states that the amount of flour in the bag (x) plus the amount of flour in the jar (4.5 cups) must be greater than or equal to 12 cups. To solve for x, we can subtract 4.5 from both sides of the equation, which yields x ≥ 7.5.

Answer: I think its -5

Step-by-step explanation:

The values of x and y are 1.8 units and 1.2 units respectively.

A perpendicular bisector is a line that bisects a line segment in two equal parts and makes an angle of 90° at the point of intersection. In other words, we can say that a perpendicular bisector divides a line segment at its midpoint making an angle of 90°.

Given that, RT = 15x + 5y, RS = 20x - 5y, WT = 40 and ST=21.

Here, RS=RT+ST

20x-5y=15x+5y+21

5x-10y=21 -------(I)

RT=ST

15x+5y=21 -------(II)

Multiply equation (II) by 2, we get

30x+10y=42 -------(III)

Add equation (I) and (III), we get

5x-10y+30x+10y=21+42

35x=63

x=63/35

x=9/5

x=1.8 units

Substitute x=1.8 in equation (I), we get

5(1.8)-10y=21

y=1.2 units

Therefore, the values of x and y are 1.8 units and 1.2 units respectively.
