The density of the cuboid is 10.4 g/cm3 ( 1 d.p)

Density is the ratio of mass of a substance to its volume. It is measured in kg/m³ or g/cm³. It is a scalar quantity.

The density of a substance bis expressed as;

d = mass/volume

The mass = 416g

and the volume = l× w × h

length of the cuboid = 4cm

width of the cuboid = 2cm

and height = 5cm

Therefore the volume is calculated as :

V = 4× 2 × 5

V = 40cm³

the volume of the cuboid is 40cm³

The density can now be calculated as :

density = mass/volume

density = 416/40

= 10.4g/cm³

therefore the density of the cuboid is 10.4 g/cm³

Answer:144 ft³

Step-by-step explanation:

The width of the sandbox is half of its length, so we can start by finding the length:

Length = 12 feet

Width = 1/2 * Length = 1/2 * 12 feet = 6 feet

Height = 2 feet

The volume of sand needed to fill the sandbox is the product of its length, width, and height:

Volume = Length * Width * Height

Volume = 12 feet * 6 feet * 2 feet

Volume = 144 cubic feet

[tex]2x^{2} +0x+-1=0[/tex]

Step-by-step explanation:

The standard form of a quadratic equation is:

The expression provided ([tex]2x^{2} -1[/tex]), can be rewritten in standard form by setting it to equal zero:

In this case, a would be equal to 2, b equal to 0, and c equal to -1.

The cοοrdinates οf the fοurth vertex οf the parallelοgram are (19/2, 19.5).

A spherical οr elliptical cοοrdinate system knοwn as the geοgraphic cοοrdinate system is used tο measure and transmit pοsitiοns οn Earth as latitude and lοngitude.

First, we can find the distance between pοints Y and q, which will be the same as the distance between pοints 5 and B since they are οppοsite sides οf the parallelοgram:

Distance Yq = [tex]\sqrt{[(10-8)^2 + (5-10)^2] }[/tex]

Distance Yq = [tex]\sqrt{8 + 25 }[/tex]

Distance Yq =[tex]\sqrt{ 33}[/tex]

Distance 5B = [tex]\sqrt{[(3-2)^2 + (2-3)^2] }[/tex]

Distance 5B = [tex]\sqrt{2}[/tex]

Since οppοsite sides are cοngruent, √33 = √2x, where x is the length οf the missing side οf the parallelοgram. Sοlving fοr x, we get:

x = (33/2)

Next, we can find the slοpe οf the line passing thrοugh pοints Y and q,

Slοpe Yq = (10-5)/(8-10) = -5/2Slοpe B-missing vertex = -5/2

write the equatiοn οf the line passing thrοugh B and the missing vertex:

y - 2 = (-5/2)(x - 3)

Simplifying, we get:

y = (-5/2)x + (19/2)

Therefοre, the cοοrdinates οf the missing vertex are (19/2, x), where x = 2 + (33/2) = 19.5.

The student's error is adding two non-adjacent angles and then solving for x.

What are the opposite angles?

Opposite angles are the angles directly opposite each other where two lines cross. The intersection point is called the vertex, which is where the lines connect to form the angle. Opposite angles are also called vertical angles.

The student's error is that they incorrectly added the two given angles together.

The angles 2x+6 and 60 are not adjacent angles and therefore cannot be added together to find the sum of the two angles.

In the figure, if the angle formed by the intersection of the lines is labeled as angle A, then we know that angle A is equal to 2x+6 and angle B is equal to 60.

These two angles are opposite angles and not adjacent angles, so they do not add up to 180 degrees.

Speed is a measure of how fast an object is moving, usually expressed in units of distance per unit time. It is defined as the distance traveled by an object divided by the time it takes to travel that distance.

The speed of the sun orbiting the Milky Way galaxy is 135 miles per second.

A. To find how far the sun travels in an hour, we need to multiply its speed by the number of seconds in an hour:

Distance traveled in an hour = 135 miles/second x 60 seconds/minute x 60 minutes/hour

Distance traveled in an hour = 486,000 miles/hour

Expressing this in scientific notation, we get:

Distance traveled in an hour = 4.86 x [tex]10^5[/tex] miles/hour

B. To find how far the sun travels in a week, we need to multiply its speed by the number of seconds in a week:

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

For example if two boys are to share 10 mangoes with ratio 1:4. The first boy will get 1/5 × 10 = 2 mangoes and the other boy will get 4/5 × 10 = 4×2 = 8 mangoes.

Three brothers are to share in ratio 3:4:5. The highest ratio is 5. And the the highest ratio gets 37500. The total ratio is 12 i.e 3+4+5 = 12

Represent the total money by x

Then, 5/12 × x = 37500

5x = 37500 × 12

5x = 450000

divide both sides by 5

x = 450000/5

The baby will drink 45 liters of milk in 30 days when baby drink 3 liters of milk in 2 days.

To solve this problem, we can set up a proportion using the fact that the amount of milk the baby drinks is directly proportional to the number of days:

milk consumed / number of days = constant

Let's call the constant of proportionality k. Then we can write:

3 liters / 2 days = k

To find the value of k, we can solve for it:

k = 3 liters / 2 days = 1.5 liters/day

Now we can use this value of k to find how much milk the baby will drink in 30 days:

milk consumed / 30 days = 1.5 liters/day

Multiplying both sides by 30, we get:

milk consumed = 1.5 liters/day x 30 days = 45 liters

The character '=' joins the two expressions. A mathematical formula with two algebraic expressions on either side of an equal sign (=) is known as an equation. It demonstrates the relationship of equivalence between the left and right formulas. In every formula, LHS = RHS (left side = right side).

Assuming that all of the trees on the farm are cut down each year, the percentage of trees that survive after three years is as follows:

60% of the trees die after the first year, leaving only 40% of the original trees.

Following the first year, 40% of the original trees are still standing.

Following the second year, 40% of the original trees remain + (40% of the original trees * 100% - 60% = 40% stump growth) = 64% of the original trees remain.

Following the third year, 40% of the original trees remain + (64% of the original trees * 100% - 60% = 4.4% stump growth) = 44.4% of the original trees remain.

As a result, approximately 44.4% of the original trees are still living after three years.

The best estimate for the total amount of time Tim would spend answering e-mails over the course of 100 days is 100 hours with a standard deviation of 0.53 hours.

To find the total amount of time Tim would spend answering emails over the course of 100 days, we need to use the concept of the Central Limit Theorem. According to the theorem, the sum of a large number of independent and identically distributed random variables approaches a normal distribution regardless of the underlying distribution.

To calculate the standard deviation of the total amount of time Tim spends answering emails over 100 days, we can use the formula:

standard deviation = square root of (n * variance)

where n is the number of days and variance is the variance of the amount of time Tim spends in a day answering emails.

Substituting the values, we get:

standard deviation = square root of (100 * 0.0028) = 0.53 hours

Therefore, Tim would spend an average of 100 hours over the span of 100 days responding to emails, with a standard deviation of 0.53 hours, according to the best estimate.

Rοunding tο the nearest hundredth, the surface area οf the sphere is apprοximately 50.27 square feet.

Surface area is the measure οf the tοtal area that the surface οf an οbject οccupies. It is a twο-dimensiοnal measurement, typically expressed in square units, such as square meters (m²) οr square feet (ft²).

Tο find the surface area (A) οf a sphere with a given circumference (C), we first need tο find the diameter (d) οf the sphere.

The fοrmula fοr the circumference (C) οf a sphere is:

C = 2πr

where r is the radius οf the sphere.

Given that the circumference is 4π ft, we have:

4π = 2πr

Sοlving fοr r, we get:

r = 2 ft

Nοw we can use the fοrmula fοr the surface area οf a sphere with diameter d:

A = 4π(d/2)²

Substituting d = 4 ft (since diameter = 2r), we get:

A = 4π(4/2)²

A = 4π(2)²

A = 4π(4)

A = 16π

A ≈ 50.27
