433 kg sample contains 433000000 milligram. A thousandth of a gram, or a metric unit of mass measurement.

A thousandth of a gram, or a metric unit of mass measurement. One millilitre, or one thousandth of a litre, of water at 4 degrees Celsius, weighs one gram. The word "milligram" is shortened to mg. Whatever the motivation, Milligram stands to gain. The Melbourne-based shop has transformed from a direct-to-consumer brand that solely operated online and sold largely stationery products to an omnichannel lifestyle brand with three brick-and-mortar stores and plans for four more in less than a year. The worldwide metric system divides solid weight into very tiny units called milligrams. A milligram is precisely one thousandth of a gram; to put it another way, a typical mosquito weighs about 2 milligrams.

433 kg = 433000000 mg.

Now that we are aware of the conversion factor, we can easily convert 433 kilograms to milligrams by multiplying 1000000 by the number of kilograms we have, which is 433.

Step-by-step explanation:

Given that,

The national dept of a country = 298,800,000​,000,000

Population of the country = 53,980​,000

We need to find the debt per person. It can be calculated by dividing national dept of a country to its total population. Let it is d.

\(d=\dfrac{298800000000000}{53980000}\\\\=5535383.47\ \text{units}\)

Hence, the debt per person is 5535383.47 units.

The fraction of crayons that are blue triangle is 1/5.

The ratio of blue rounds to non-blue crayons is

The fraction of footballs that are brown rubber footballs is 8/15 and here are 4 times as many rubber footballs as non-rubber footballs

A fraction represents a part of a whole.

1. Let's say Alexa had a total of 5x crayons in the bag.

the number of blue crayons in the bag is 2x,

There is one triangle for every two round crayons,

(1/2) × 2x = x (By condition)

So, the fraction of crayons that are blue triangle is x / 5x = 1/5.

The number of blue round crayons is 2x.

The number of non-blue crayons is 5x - 2x = 3x,

The ratio of blue rounds to non-blue crayons is 2x / 3x = 2/3.

2.

4 out of 5 wall footballs are rubber, 4/5 of the footballs in the bag are rubber.

The fraction of rubber footballs that are brown is 2/3.

The fraction of footballs that are brown rubber footballs is (4/5) × (2/3) = 8/15.

The fraction of non-brown rubber footballs is (4/5) - (8/15) = 4/15.

The ratio of rubber footballs to non-rubber footballs is (4/5) / (1/5) = 4.

So there are 4 times as many rubber footballs as non-rubber footballs

Hence,  the fraction of crayons that are blue triangle is 1/5.

Answer:

Let R be the radius of the tank, H(t) the height of the water at time t, and V(t) the volume of the water. The quantities V(t), R and H(t) are related by the equation

V(t) = πR²H(t) ___(1)

The rate of increase of the volume is the derivative with respect to time,

dV/dt

and the rate of increase of the height is

dH/dt

We can therefore restate the given and the unknown as follows

Given:

dV/dt = 4m³/min

Unknown:

dH/dt

Now we take derivative of each side of (1) with respect to t:

dV/dt = πR²dH/dt

So

dH/dt = 1/πR²dV/dt

Substituting R = 3 m and dV/dt = 4m³/min we have

dH/dt = 1/π(3)² ⋅ 4 = 4/9π

The value of `csc 0.71` to three  decimal places is `1.534` which is option A.

The equation for the graph shown in the right is `y=x²(x-3)` which is option C.The graph of the function `y=x¹` is transformed to the graph of the function `y=

-[2(x + 3)]* + 1`

by a vertical stretch by a factor of 2, a reflection in the x-axis, a translation of 3 units to the right, and a translation of 1 unit up which is option A.

The equation of `f(x)` if `D = (x = Rx)` and the y-intercept is `(0,-2)` is `

f(x) = 2x + 1`

which is option B.

The value of `csc 0.71` to three decimal places is `1.534` which is option A.4. Given a graph, we can find the equation of the graph using its intercepts, turning points and point-slope formula of a straight line.

The graph shown on the right has the equation of `

y=x²(x-3)`

which is option C.5.

The graph of `y=x¹` is a straight line passing through the origin with a slope of `1`. The given function `

y=-[2(x + 3)]* + 1`

is a transformation of `y=x¹` by a vertical stretch by a factor of 2, a reflection in the x-axis, a translation of 3 units to the right, and a translation of 1 unit up.

So, the correct option is A as a vertical stretch is a stretch or shrink in the y-direction which multiplies all the y-values by a constant.

This transforms a horizontal line into a vertical line or a vertical line into a taller or shorter vertical line.6.

The function is given as `f(x)` where `D = (x = Rx)` and the y-intercept is `(0,-2)`. The y-intercept is a point on the y-axis, i.e., the value of x is `0` at this point. At this point, the value of `f(x)` is `-2`. Hence, the equation of `f(x)` is `y = mx + c` where `c = -2`.

To find the value of `m`, substitute the values of `(x, y)` from `(0,-2)` into the equation. We get `-2 = m(0) - 2`. Thus, `m = 2`.

Therefore, the equation of `f(x)` is `

f(x) = 2x + 1`

which is option B.7. `csc(0.71)` is equal to `1/sin(0.71)`. Using a calculator, we can find that `sin(0.71) = 0.649`.

Thus, `csc(0.71) = 1/sin(0.71) = 1/0.649 = 1.534` to three decimal places. Hence, the correct option is A.

Area of Circle = pi * r* r

This means that the car needs to go at least 64 mph to overtake the bus in 5 hours, and it needs to cover the same distance as the bus did in those 3 hours, which is 120 miles.

To figure out the speed the car needs to go to overtake the bus in 5 hours, we first need to figure out how far the bus travels in those 5 hours.

Since the bus travels for 3 hours before the car starts, we can find the distance the bus travels in those 3 hours by using the formula:

distance = rate × time

where the rate is the speed of the bus, which is 40 mph, and the time is 3 hours.

So the distance the bus travels in those 3 hours is:

distance = 40 mph × 3 hours = 120 miles

Now, for the car to overtake the bus in 5 hours, it needs to cover the same distance the bus did in 3 hours plus some additional distance to get ahead of the bus. Let's call this additional distance "x".

So, the total distance the car needs to travel is:

total distance = 120 miles + x

Now we can set up an equation that relates the distances and speeds of the car and the bus:

distance covered by car = distance covered by bus + x

rate of car × time = rate of bus × time + x

where the rate of the bus is 40 mph, the time is 5 hours (since that's how long it takes for the car to overtake the bus), and the rate of the car is what we're trying to find.

Substituting the values we know:

rate of car × 5 hours = 40 mph × 8 hours + x

Simplifying:

rate of car = (40 mph × 8 hours + x) / 5 hours

We still need to find the value of "x". To do this, we can use the fact that the car overtakes the bus, which means that the distance covered by the car is greater than the distance covered by the bus:

distance covered by car > distance covered by bus

rate of car × time > rate of bus × time

rate of car × 5 hours > 40 mph × 8 hours

rate of car > 64 mph

So the car needs to go faster than 64 mph to overtake the bus in 5 hours.

To find the value of "x", we can substitute the rate of the car into the earlier equation:

rate of car × 5 hours = 40 mph × 8 hours + x

64 mph × 5 hours = 40 mph × 8 hours + x

320 miles = 320 miles + x

x = 0

In linear algebra, a nonzero vector is said to have an eigenvector, or characteristic vector, when a linear transformation is applied to it; this characteristic vector only changes by a scalar amount. The scaling factor for the eigenvector is known as the associated eigenvalue, frequently represented by the symbol. Linear transformations are made intelligible by the usage of eigenvectors. Eigenvectors can be thought of as a non-directional stretching or compressing of an X-Y line chart. In mathematics, eigenvalues are regarded as the factor by which a transformation is stretched, whereas eigenvectors are the real non-zero eigenvalues that point in the direction stretched by the transformation. The direction of the transformation is negative if the eigenvalue is negative.

The equation provided seems to contain multiple variables and possibly partial derivatives, but it is not clear how they are related or what the equation represents.

The equation y" - 2y = 2e" represents a second-order linear homogeneous differential equation. To solve this equation, we can first find the characteristic equation by substituting y = e^(mx) into the equation:

m²e^(mx) - 2e^(mx) = 0

Simplifying the equation, we get:

m² - 2 = 0

Solving for m, we find the roots of the characteristic equation:

m₁ = √2

m₂ = -√2

The real general solution of the given differential equation is:

y(x) = C₁e^(√2x) + C₂e^(-√2x)

where C₁ and C₂ are constants determined by initial conditions or boundary conditions.

The equation z'y" + 3xy + 5y = 0 represents a second-order linear non-homogeneous differential equation. To solve this equation, we can use the method of variation of parameters. First, we find the complementary solution by solving the associated homogeneous equation z'y" + 3xy + 5y = 0. Then, we find a particular solution using the variation of parameters method.
