Step-by-step explanation:

The value of x in the given right cone is 10 units.

A cone is a geometrical shape in three dimension formed by a set of lines joined from a point to every points on the base surface which is a  circle.

The common point where the lines join is called apex.

The distance from apex to the circular base is called the height of the cone.

The radius of the circular base is also the radius of the cone.

Volume of a Cone is calculated as V = \(\frac{1}{3}\) πr²h, where h is the height of the cone and r is the radius of the cone.

We have, Volume of the cone = 30π units³.

From the figure given, diameter of the circular base = 6 units

So, the radius of the cone = 6/2 = 3 units

We have to find the height of the cone.

Substituting these values in the equation for the volume,

30π = \(\frac{1}{3}\) π × 3² × h

30 = = \(\frac{1}{3}\) × 3² × h

30 = 3h

h = 10

Hence, the height of the cone with radius 3 units and volume 30π units is 10 units.

The density of the unknown metal exists 8.9 g/mL.

The mass of an object divided by its volume is how dense it is. The gram per cubic centimeter (g/cm³) unit of density is frequently used. How much mass is present in a given area is referred to as density. Try to picture a drawer full of socks. Its density is particular. Consider that when you remove a sock, the drawer's density changes. This is due to the socks' shifting mass while the drawer's remaining constant volume.

The definition of density is the mass of a substance per unit volume. The degree to which matter is packed together is fundamentally measured by density. It is a specific physical quality of a specific object. Greek scientist Archimedes is credited with discovering the density principle.

The density (D) is equal to mass (m) divided by volume (V): D = m/V

To find the mass of the object:

m = 156 g - 105.5 g = 50.5 g

To find the volume of the volume:

V = 30.7 mL - 25 mL = 5.7 mL

The density is:

D = m/V = 50.5 g  / 5.7 mL = 8.9 g/mL

Therefore, the density exists 8.9 g/mL.

The complete question is:

A graduated cylinder was filled with water to the 25.0 mL mark and weighed. Its mass was 105.5g. An object made of an unknown metal was placed in the cylinder and completely submerged in the water. The water level rose to 30.7 mL. When reweighed, the cylinder, water and metal object had a total mass of 156.0g. Based on these measurement, what is the density of the unknown metal?

The algebric expression -1/4 + 3/5 is equal to 7/20 when simplified.

To solve the expression -1/4 + 3/5, we need to find a common denominator for the fractions and then perform the addition.

The common denominator for 4 and 5 is 20. We can rewrite the fractions with this denominator:

-1/4 = -5/20

3/5 = 12/20

Now that the fractions have the same denominator, we can add them:

-5/20 + 12/20 = (-5 + 12)/20 = 7/20

Therefore, -1/4 + 3/5 is equal to 7/20.

To further simplify the fraction, we can check if there is a common factor between the numerator and denominator. In this case, 7 and 20 have no common factors other than 1, so the fraction is already in its simplest form.

Thus, the final answer is 7/20.

We have to identify the sampling technique used in each case:

6) Using a random table corresponds to a simple random sampling.

7) We can consider the top 10 students as a strata of the class. As the sample only includes this strata, it can be considered a stratified sampling.

8) In this case, the sampling is initially random but following a deterministic interval (in this case, position in the line). This correspond to a sytematic sampling.

9) In this case, the hospitals are the clusters. Each cluster is then surveyed completely.

As the researcher surveyed all individuals within each hospital, this is a cluster sampling.

10) The 10 barangays are selected randomly from the population without any special criteria, so it is a simple random sampling.

What is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

125a + 65s = 1200

Answer:

B and E

Step-by-step explanation:

the graph (Justine) shows the line

y = 2x

the line for Velma is

y = 4x

now we need to remember that the slope (inclination) of a line is the factor of x (so, 2 and 4 in the two line equations).

a slope is expressed as y/x and indicates how many units y changes when x changes a certain amount of units (like 1).

as described (and also confirmed by the graph) the x units are minutes, and the y units are meters.

so, as per her slope, Velma moves 4 meters in 1 minute.

and Justine moves 2 meters in 1 meter.

so, Justine is half as fast as Velma.

and therefore, Justine moves a shorter distance than Velma each minute.

A parabola is a cross-section cut out of the cone and represented by an equation x = y².

here,
The given graph is of the left parabola,
-x = y²
When we translate the above expression 4 units right we get the graph,
So
-x + 4 = y²

put y = j(x)

-x + 4 = j(x)²
j(x) = [-x + 4]¹/²

Thus, the required equation that represents the graph is j(x) =  (-x + 4)¹/². Option D is correct.

Answer:

Net price = $385.28

Step-by-step explanation:

Trade Discount - It is the discount given by buyer to seller, as a reduction in list price, when huge (bulk) orders transactions are made.

List price = 481.60

Trade Discount = 20%

So, Trade Discount = 20 / 100 (481.60) = 96.32

Net price = List price - Trade Discount = 481.60 - 96.32 = 385.28

Determine 20% of the initial level

20% → 0.2

Write the equation with half-life of 12 hours and initial dose of 25 mg.

Substitute y = 5, and solve for t

Get the natural logarithm of both sides

Rounding the answer to the nearest whole number, the time it takes for the initial dose to be reach 20% of its initial level is 28 hours.

Answer:

15

Step-by-step explanation:

Multiply: 25x.60=15

The reason why you multiply 25 times .60 is because you need to change the percentage to a decimal. The way you change you from a percentage to a decimal is by moving the decimal twice to the left.

Answer:(-32,12)

Step-by-step explanation:

Find the change in x and change in y from point x to point y. In this case it is -20 for x and +11 for y. Since the definition of a midpoint splits the line into 2 equal segments you can use the changes to calculate z. Use the midpoint coordinates and add the changes like this: (-12-20,1+11) and you will get (-32,12) for z.

Step-by-step explanation:

We know that two vertical angles are equal.

\(108° \: = \: (12x \: + \: 24)°\)

\( - 12x \: = \: 24 \: - \: 108\)

\( - 12x \: = \: -84\)

\( \boxed{ \bold{x \: = \: 7°}}\)

We know that a complete angle measures 360°.

\(108° \: + \: 108° \: + \: z \: + \: z \: = \: 360°\)

\(216 \: + \: 2z \: = \: 360\)

\(2z \: = \: 360 \: - \: 216\)

\(2z \: = \: 144\)

The six trigonometric functions at 11π/3 are as follows-

sin (11π/3) = -\(\sqrt{3}\)/2

cos (11π/3) = 1/2

tan (11π/3) = -\(\sqrt{3}\)

cot (11π/3) = -1/\(\sqrt{3}\)

sec (11π/3) = 2

cosec (11π/3) = -2/ \(\sqrt{3}\)

Let us evaluate the six trigonometric functions at 11π/3 as follows -

11π/3 can be written as (6π+5π)/3 = 2π + 5π/3.

a. sin (11π/3) = sin (2π + 5π/3)

this angle is greater than or equal to 0 and less than 2π.

= sin (5π/3)

Finding the angle with equivalent trigonometric values in the first quadrant. Also, sin is negative in the 4th quadrant.

= -sin (π/3)

= -\(\sqrt{3}\)/2

Hence, sin (11π/3) = -\(\sqrt{3}\)/2

b. cos (11π/3) = cos (2π + 5π/3)

this angle is greater than or equal to 0 and less than 2π.

= cos (5π/3)

Finding the angle with equivalent trigonometric values in the first quadrant. Also, cos is positive in the 4th quadrant.

= cos (π/3)

= 1/2

Hence, cos (11π/3) = 1/2

c. tan (11π/3) = tan (2π + 5π/3)

this angle is greater than or equal to 0 and less than 2π.

= tan (5π/3)

Finding the angle with equivalent trigonometric values in the first quadrant. Also, tan is negative in the 4th quadrant.

= -tan (π/3)

= -\(\sqrt{3}\)

Hence, tan (11π/3) = -\(\sqrt{3}\)

d. cot (11π/3) = 1/ tan (11π/3)

Hence, cot (11π/3) = - 1/ \(\sqrt{3}\)

e. sec (11π/3) = 1/ cos (11π/3)

Hence, sec (11π/3) = 2

f. cosec (11π/3) = 1/ sin (11π/3)

Hence, cosec (11π/3) = -2/ \(\sqrt{3}\)

1/4π radians is approximately equal to 45 degrees.

To convert a value from radians to degrees, multiply the value by 180/π. For example, to convert π/4 radians to degrees, multiply π/4 by 180/π to get 45 degrees. This conversion is useful for converting angles between the two units of measurement.

Degrees = Radians × 180/π.

Therefore, to convert 1/4π radians to degrees, we have:

Degrees = (1/4π) × (180/π) ≈ 45°

Hence, 1/4π radians is approximately equal to 45 degrees.
