Answers

I would expect the answer to be a lot greater than 24 which is 12000.

What is percentage?

Percentage is defined as the part of a whole value per 100 which is represented by the symbol%.

To find the number in which 24 is it's 0.2%, the following is carried out;

The number is represented as = x

That is, 0.2/100 × X = 24

0.2x/100 = 24

0.2x = 100×24

0.2x = 2400

X = 2400/0.2

X= 12000

Therefore, 24 is 0.2% of the number 12000 which can be said that it's alot greater than 24.

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.

A. Graph the equation and look at the table to find the y-value when x=-5


B. Graph the equation and find the y-value of the ordered pair when x=-5


C. Substitute (-5) wherever there is an x and solve using a calculator


D. See what x is when y=-5

Answers

Answer: D option is not the correct way to evaluate.

Step-by-step explanation: To find out f(x) which is also known as y.

so, f(x) = 3x^{2} - 2x + 5

f(-5) = 3 × 25 - 2(-5) + 5

= 75 + 10 + 5

Here we see here that four alternatives are given to find out but the option D is not appropriate.

A. By drawing a graph one can easily find out the value here we will try to find out the graph line and then by drawing it on the graph.

B.  Similar to option A we can find out using option B

C. I had also used the same method to calculate for the value of (-5) above so this option is also correct.

D. When y= -5 then if we find out it for x will not work as here we have to find out f(x) which is function of X i.e. simply Y. so this won't work.

The following option is not a possible way to evaluate that function:

How much chocolate will each person get if 4 people share

Answers

Each person will receive two ounces of chocolate.

What is equality?

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.

A train does a journey without stopping in 8 hours. if it had traveled 5 km an hour faster, it would have done the journey in 6 hours 40 min. what is its slower speed?

Answers

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

What is the relation between time, distance & speed ?

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

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

The midpoint of AB is M(1, -3). If the coordinates of A are (-6, -7),

Answers

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

What do you mean by midpoint?

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).

Which values complete the table for h(r)?

Answers

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

What is an expression?

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.
