Step-by-step explanation:

The approximate lateral area of the cone is solved to be 314 cm²

From the question we get that:

The area of the circular base of a cone is 25π cm²

25π cm² =  πr²

the slant height of the cone is four times the radius of the cone

L = 4r

Lateral area of the cone

= πrl square units.

solving for r

25π cm² =  πr²

r² = 25

r = 5

solving for the lateral area of the cone

= πrl square units.

= π * 5 * 4r  

= π * 5 * 4 * 5

= 100π

= 100 * 3.14

= 314 cm²

Therefore , the solution of the given problem of angles comes out to be

x =  42.5° and  y = 20°.

In Euclidean geometry, an arc is a construct made up of two rays that split at the apex and vertex, which are located in the middle of the angle. The sides or loops are the name given to these rays. A combination of two rays may result in an inclination that is inside the surfaces in which they are located. Two planes can be combined to form an angle as well. They are referred to as dihedral angles. Two line rays with end points can be arranged in a variety of ways to create styles in two dimensions.

Here,

Given :

=> 4y + 5y = 180°

=> 9y = 180°

=> y = 180°/9

=> y = 20°

and

=> 2x + 5 + 90° = 180°

=> 2x + 95° = 180°

=> 2x = 85°

=> x =  42.5°

Therefore , the solution of the given problem of angles comes out to be

The train which is travelled same distance with two different speeds, the slower speed of a train is 25.075 km/hr

The distance covered by the object is equal to the product of the speed at which the object is moving and time taken for covering the distance.

Distance = Time × Speed

Given that,

A train does a journey without stopping in 8 hours

it had traveled 5 km/hr faster , Time taken = 6 hours 40 min = 6.67hr

slower speed = ?

Suppose total distance covered =  X

⇒  X = V × 8    _____(i)

If he travelled 5 km/hr faster

⇒  X = (V+5) × 6.67  _____(ii)

For i and ii distance is same so we can equate both the values,

⇒ V × 8  = (V+5) × 6.67

⇒ 8V = 6.67V + 33.35

⇒ 1.33V = 33.35

⇒ V = 25.075

Hence, the slower speed is 25.075 km/hr

Each person will receive two ounces of chocolate.

Equality in math is a concept that states that two values, expressions, or quantities are the same. It is symbolized by the equal sign "=" and is used to express that two values are equivalent. Equality is an important concept in math and is used in solving equations, simplifying expressions, and comparing different numbers. Equality can also be used to show that two quantities are balanced, such as in the equation x+7=10. Equality is a fundamental principle of mathematics that is used in many different areas.

If four people share one-third of a pound of chocolate equally, each person will receive approximately two ounces of chocolate. This can be calculated by dividing the total amount of chocolate (one-third of a pound) by the number of people (four), which gives 0.375 pounds per person. Since there are 16 ounces in a pound, 0.375 pounds is equal to six ounces. Since two of those ounces are not divisible into equal portions, each person will receive two ounces of chocolate.

The coordinates of B are (-4, -1).

Midpoint is a point that is exactly halfway between two other points. It can refer to the center of a line segment between two points or the average value of a set of numbers. In geometry, the midpoint of a line segment is the point that divides it into two equal parts. In mathematics, the midpoint formula is used to find the midpoint of a line segment given the coordinates of its endpoints.

The midpoint of a line segment is found by taking the average of the coordinates of the endpoints. So for the midpoint M(1, -3), the coordinates of A and B are:

A(-6, -7), B(x, y)

The x-coordinate of M is the average of the x-coordinates of A and B, so:

(x - (-6)) / 2 = 1

Solving for x, we find:

x = -6 + 2 * 1 = -4

Similarly, the y-coordinate of M is the average of the y-coordinates of A and B, so:

(y - (-7)) / 2 = -3

Solving for y, we find:

y = -7 + 2 * (-3) = -1

Therefore, the coordinates of B are (-4, -1).

The perimeter of the trapezium DBCE is 32.2 cm

What is perimeter?

The complete length of a shape's edge serves as its perimeter in geometric terms. Adding the lengths of all the sides and edges that surround a form yields its perimeter. It is calculated using linear length units such centimeters, meters, inches, and feet.

First find the unknown side lengths of  trapezium DBCE:

ABC and ADE are similar triangles.

So, we have

AB/AD = AC/AE = BC/DE

=>  10/4 = AC/5.8 = BC/5

=> 2.5= AC/5.8       and       2.5=BC/5

=> AC=2.5*5.8         and     BC=2.5*5

=> AC=14.5             and       BC=12.5

EC=AC-AE = 14.5-5.8 = 8.7  

Perimeter is sum of all sides

Perimeter = DB+BC+EC+DE

                 = 6+12.5+8.7+5

                 = 32.2 cm

where y is the total cost, x is the number of tacos,

m is the slope (the cost per taco), and b is the y-intercept (the cost of the drink).

So in this case,

m = 0.75 (the cost per taco),

b = 1.75 (the cost of the drink), and

The probability of selecting 3 cans (mango juice) is found as 1/230.

For the stated question:

As the can had been taken without replacement.

Thus,

Probability that 1st can is of mango = Total mango cans / Total cans

                                                           = 5 / 25

                                                           = 1/5

Probability that 2nd can is of mango = Mango cans left/ Total left cans

                                                           = 4 / 24

                                                           = 1/6

Probability that 3rd can is of mango = Total mango cans / Total cans

                                                           = 3 / 23

Thus,

probability of selecting 3 cans (mango juice) = 1/5 * 1/6 * 3/ 23

                                                                          =  3/690

                                                                          =  1 /230

The compound experiment is the probability of heads on a coin and 4 on a number cube which is P = ( 1/12 )

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

The values of h(r) for the given r - values can be calculated by substituting the values of Volume and r into the formula,

⇒ V = πr²h

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

For the given table, we need to find the values of h(r) for the given r -values.

To do this, we can use the formula for the volume of a cylinder

⇒ V = πr²h.

We know that for a given r - value, the volume is given by the second column in the table. We can therefore substitute the values of V and r into the formula to calculate the corresponding h value.

For example, for r = 10, the corresponding volume is V = 4772. Substituting this into the formula, we get ;

⇒ h = 4772/(π10²)

       = 6472 cm.

This process can then be repeated for the remaining r - values to complete the table.

Thus, The values of h(r) for the given r - values can be calculated by substituting the values of V and r into the formula Volume = πr²h.

After solving given quadratic equation, x=9.

What are quadratic equations ?

A quadratic equation is a second-degree algebraic equation in x. In its usual form, the quadratic equation is ax^2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first requirement for an equation to be a quadratic equation is that the coefficient of x^2 is not zero (a ≠ 0). When expressing a quadratic equation in standard form, the x^2 term comes first, then the x term, and lastly the constant term. The numeric values a, b, and c are commonly expressed as integral values rather than fractions or decimals.
