one bucket of gravel has a mass of 7.05 kg. what is the mass of 20 buckets of gravel in kilograms?

Answer:

Total ant is 1,513,000,000

Step-by-step explanation:

I. When 100 cm = 1 m

           1,000m = 1kg

So  1,000 * 100 cm = 1 m * 1,000

        100,000 cm = 1,000m or 1 kg

II. If 1 ant length = 0.1 cm

         \(\frac{1}{0.1 cm} = \frac{x}{100,0000 cm}\)

         \(\frac{100,000}{0.1}\) = x

            x = 1,000,000

So in 1 kg will be 1 million ant.

II. The distance btw NYC and Disney Land is 1,513 kg.

  1,000,000 * 1,513

That make 1,513,000,000 ants.

Sorry for late.

Answer:

C: (-5, 1)

Step-by-step explanation:

If you put the equation in a graphing calculator and examine all the points, C is the only one not on the line.

The minimum length of the third side must be greater than 16 feet.

The minimum length of the third side can be determined using the Triangle inequality theorem. This theorem states that the sum of any two sides of a triangle must be greater than the length of the third side. The Triangle Inequality Theorem can be expressed by the following inequality: a + b > c, where a, b, and c are the lengths of the three sides of the triangle. In this case, we have two sides of 4 feet and 12 feet, so the inequality can be written as 4 + 12 > c, which simplifies to 16 > c. Solving for c yields c > 16, which means that the minimum length of the third side must be greater than 16 feet.

The Amount of pepperoni used = 9 packages, Amount of sausage used= was 0.9375 packages of pepperoni, so the chef used 8.0625 more packages of pepperoni than sausage.

Multiplication is a basic arithmetic operation that involves combining or adding equal groups of numbers. It is represented by the symbol "x" or "*", and the result of multiplying two or more numbers is called the product. For example, 2 x 3 = 6, which means two groups of three (2 multiplied by 3) equals six.

The chef used 9 packages of pepperoni and 3/8 of a package of sausage. To compare the amount of pepperoni and sausage used, we need to express them in a common unit of measurement. We can do this by converting the 3/8 package of sausage to the equivalent amount in packages of pepperoni.

To do this, we can notice that 1 package of sausage is equivalent to 2.5 packages of pepperoni. Therefore, we can find the amount of sausage in packages of pepperoni as:

(3/8) package of sausage * 2.5 packages of pepperoni per 1 package of sausage = (3/8) * 2.5 packages of pepperoni = 0.9375 packages of pepperoni

Now, we can compare the amount of pepperoni and sausage used:

Amount of pepperoni used = 9 packages

Amount of sausage used = 0.9375 packages of pepperoni

To find the difference, we can subtract the amount of sausage used from the amount of pepperoni used:

9 packages of pepperoni - 0.9375 packages of pepperoni = 8.0625 packages of pepperoni

Therefore, the chef used 8.0625 more packages of pepperoni than sausage.

Therefore, the Amount of pepperoni used = 9 packages, Amount of sausage used= was 0.9375 packages of pepperoni, so the chef used 8.0625 more packages of pepperoni than sausage.

Well let's make this simply by focusing on elevator number 1

it is on the 6th floor so we represent that as

6

Now it goes up 7/4 which is also the same as 1 3/4

the equation looks like this:

6+1 3/4

Add them together:

7 3/4

Now it goes down 10 meaning it is -10 add that to the equation:

7 3/4 - 10

Which is -2 1/4

Elevator number 1 is at floor number -2 1/4

Now for Elevator number 2

It is on the 20th floor which will make the equation looks like this:

20

Now it goes down five floors three times which can be represented like this:

20-5(3)

Simplify (Multiplication goes first according to the Order of Operations)

20-15= 5

Now it is 5 but it goes up 12 floors so the equation looks like this:

5+12

Therefore, the area of the quarter circle of radius 8 cm is 16π square centimeters (or approximately 50.2655 square centimeters if we use a decimal approximation for π).

A circle is a two-dimensional shape that is defined as the set of all points that are a fixed distance (called the radius) from a central point (called the center) in a plane. It is one of the most basic geometric shapes and is often used in a variety of mathematical and scientific contexts. One important thing to note about circles is that they are symmetrical: any line passing through the center of a circle divides the circle into two halves that are mirror images of each other. Circles are commonly used in a variety of contexts, including geometry, trigonometry, physics, engineering, and many other fields. They are also used in everyday life, such as in the design of wheels and other circular objects, the calculation of the areas of circular fields or gardens, and the measurement of circular objects like plates and bowls.

Here,

The formula for the area of a quarter circle is given by:

A = (1/4)πr²

where A is the area of the quarter circle, r is the radius of the circle, and π is the mathematical constant pi (approximately 3.14159).

In this case, the radius of the quarter circle is 8 cm, so we can substitute this value into the formula and simplify as follows:

A = (1/4)π(8 cm)²

A = (1/4)π(64 cm²)

A = 16π cm²

If Leyanna choose one marble at random, the chances that it is yellow is 4/9 that is 0.44.

Total number of marbles in bag are 9

There are 5 red marbles and 4 yellow marbles

Total number of marbles = 5 + 4 = 9.

Therefore total number of cases is 9

Since there are 4 yellow marbles, the number of favorable outcomes is 4.

So P ( a yellow marble) =Number of favorable cases/ Total number of cases

To graph the solution set to the given system of inequalities, we can begin by graphing the two inequalities separately. For the first inequality, y > x^2 – 2, we can graph the function y = x^2 – 2 on the coordinate plane and shade the region above the graph. This will represent the values of x and y that satisfy the inequality.

For the second inequality, y ≥ –x^2 + 5, we can graph the function y = –x^2 + 5 on the coordinate plane and shade the region below the graph. This will represent the values of x and y that satisfy the inequality.

Next, we can combine the two graphs by intersecting the shaded regions. The resulting graph will show the solution set to the system of inequalities. The solution set can be identified as the points on the coordinate plane that are contained within the shaded region on the combined graph.

Overall, to modify the graphs of f(x) and g(x) to graph the solution set to the given system of inequalities, we can graph the functions y = x^2 – 2 and y = –x^2 + 5 on the coordinate plane and shade the regions that satisfy the inequalities. The solution set can then be identified as the points within the shaded region on the resulting combined graph.

Step-by-step explanation:

There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.

To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.

Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.

Therefore, the number of different votes possible is m * (m-1) / 2.

In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.

The mathematical expression y(x,t) = Asin(kx)sin(wt) provides a way to describe the behavior of a standing wave in terms of its amplitude, frequency, and location along the string.

At time t=0,

the standing wave can be mathematically expressed as

y(x,0) = Asin(kx)sin(w*0) = Asin(kx)sin(0) = 0.

This means that the displacement of the string is zero at time t=0.

However, it is important to note that this does not mean that the string is not moving at all. Rather, it means that the string is in a state of equilibrium at time t=0, with the maximum transverse displacement being A.

As time progresses, the standing wave will oscillate between the maximum positive and negative transverse displacement values, creating a pattern of nodes (points of zero displacements) and antinodes (points of maximum displacement).

The wave number k and angular frequency w are both constants that are dependent on the physical properties of the string and the conditions under which the wave is being produced.

The standard deviation of your revenues in a day is 14.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Let x be the revenue from hats.

And let y be the revenue from sunglasses.

And z be the total revenue.

Then according to the question:

z = 10x + 5y

You know the expected number of hats sold in a day is 10 with standard deviation 1.

σₓ = 1

σy = 2

Taking squares of both of the equation.

σₓ² = 1² = 1

σy² = 2² = 4

To find the standard deviation of your revenues in a day:

V(z) = (10)²σₓ² + 5²σy²

V(z) = (100)(1) + (25)(4)

V(z) = 200

Standard deviation,

σz² = √(200)

σz² = 10√(2)

σz² = 14.14

σz² ≈ 14

Therefore, the required standard deviation is 14.
