What is the result when the number 24 is increased by 6%?

Answers

Answer:

24 increased by 6% = 25.44

Step-by-step explanation:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

6% = 6/100 = 6 ÷ 100 = 0.06.

100% = 100/100 = 100 ÷ 100 = 1.

ncrease the number by 6% of its value.

Percentage increase = 6% × 24

New value = 24 + Percentage increase

Calculate the New Value

New value =

24 + Percentage increase =

24 + (6% × 24) =

24 + 6% × 24 =

(1 + 6%) × 24 =

(100% + 6%) × 24 =

106% × 24 =

106 ÷ 100 × 24 =

106 × 24 ÷ 100 =

2,544 ÷ 100 =

25.44

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 24 =

25.44 - 24 =

1.44

Proof.

Calculate percentage increase...

... And see if we get as a result

the absolute change (actual difference).

Percentage increase =

6% × 24 =

6 ÷ 100 × 24 =

6 × 24 ÷ 100 =

144 ÷ 100 =

1.44

So we have proven that the calculations are correct.

For positive numbers

Absolute change (actual difference) =

Percentage increase

Answer:

24 increased by 6% = 25.44

Absolute change (actual difference):

25.44 - 24 = 1.44

Answer:

24,06

Step-by-step explanation:

[tex] \sf 24 + 6 \%[/tex]

[tex] \sf = 24 + \frac{6}{100} [/tex]

[tex] = \sf \frac{2400}{100} + \frac{6}{100} [/tex]

Hello there!

When we are given the graph of a line and two points on the graph, we can calculate the slope of the line using Rise/Run.

Rise=How many units we move up (here, the rise is 3)

Run=How many units we move left or right (Here, the run is 5)

So the slope of this line is [tex]\frac{3}{5}[/tex]

Miguel Ponce has P1,500.00 cash. If he bought a pair of shoes for P1,325.00, what is the percent of the remaining cash he has left?

Answers

Answer:

Step-by-step explanation:

Cash remaining=P1, 500.00-P1,325.00

                         =P175

Percent of the remaining cash=      Cash Remaining        × 100

                                                     Cash he originally had

                                                =  P175 × 100

                                                  P1 500        

                                                =11[tex]\frac{2}{3}[/tex] %or 11.6666666% or 11.67% when rounded to two decimal places.              

A percentage is a way to describe a part of a whole. The percent of the remaining cash he has left is 11.667%.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Value of the Remaing Cash = P1,500.00 - P1,325.00

                                              = P175.00

Now, the percent of the remaining cash he has left can be written as,

Percentage of remaining cash = (Remaining cash/ Total cash) × 100%

                                                   = (P175.00 / P1,500.00) × 100%

                                                   = 0.011667 × 100%

                                                   = 11.667%

Hence,  the percent of the remaining cash he has left is 11.667%.

Here's the solution :

1. The given figure is of a Rectangle, and we know that diagnonals of a Rectangle bisects each other.

so, PR = 2 × PT

that is :

PR = 2 × 10 = 20 units

and both the diagnonals of a Rectangle are equal,

PR = QS = 20 units

2. let's take the length of PQ = x and QR = y

Angle RPS = Angle PRQ = 60°

(because they form pair of Alternate Interior angles, which are equal)

By using trigonometry :

[tex] \sin(60) = \dfrac{x}{20} [/tex]

[tex] \dfrac{ \sqrt{3} }{2} = \dfrac{x}{20} [/tex]

[tex]x = \dfrac{20 \times \sqrt{3} }{ {2} } [/tex]

[tex]x = 10 \sqrt{3} \: \: units[/tex]

similarly,

[tex] \cos(60) = \dfrac{y}{20} [/tex]

[tex] \dfrac{1}{2} = \dfrac{y}{20} [/tex]

[tex]y = \dfrac{20}{2} [/tex]

[tex]y = 10 \: \: units[/tex]

And now, we know that area of triangle PQR is equal to :

[tex] \dfrac{1}{2} \times base \times height[/tex]

[tex] \dfrac{1}{2} \times x \times y[/tex]

[tex] \dfrac{1}{2} \times 10 \sqrt{3} \times 10[/tex]

Given the vertex ( 4, 6 )and the point(1, -3), write the vertex form equation of the quadratic
function.

Answers

Answer:

[tex]\displaystyle f(x) = -(x-4)^2 + 6[/tex]

Step-by-step explanation:

A given quadratic has its vertex at (4, 6) and the point (1, -3). We want to write the equation in vertex form of the quadratic.

Recall that vertex form is given by:

[tex]\displaystyle f(x) = a(x-h) ^2 + k[/tex]

Where (h, k) is the vertex and a is the leading coefficient.

Since our vertex is at (4, 6), h = 4 and k = 6:

[tex]\displaystyle f(x) = a(x - 4)^2 + 6[/tex]

To determine the leading coefficient, since we are given that (1, -3) is a point on the parabola, when x = 1, y = -3. Substitute and solve for a:

[tex]\displaystyle \begin{aligned} (-3) & = a((1)-4)^2 + 6 \\ \\ -3 & = a(-3)^2 + 6 \\ \\ 9a & = -9 \\ \\ a & = -1 \end{aligned}[/tex]

Hence, the leading coefficient a is -1.

Then our equation in vertex form is:

[tex]\displaystyle f(x) = -(x-4)^2 + 6[/tex]

The probability of the next being white is 6/18 or 1/3.

Multiply them together because these are independent events that must all occur and we get 2*7*1= 14 as the numerator

Answers

To find the area of the path, we'll need to find the area of the space with the path and subtract the area of the inner space.

Total area: (80 + w)(50 + w)

Inner area: 80 x 50

Area of the path: (80 + w)(50 + w) - (80 x 50)

(4000 + 80w + 50w + w^2) - (4000)

4000 + 130w + w^2 - 4000

w^2 + 130w

w(w + 130)

Expression for the total area: (80 + w)(50 + w)

Ob. 3099 mi
Oc. 8,024,083 mi
O d. 8024 mi

Answers

Answer:  Choice B)  3099 mi

=============================================================

Explanation:

4,987,000 meters = 4,987 kilometers

Divide by 1000 to go from meters to kilometers. This is because 1 km = 1000 m. Or in short, we just chop off those last three zeros at the end.

Also, because 1 mile = 1.609 km (approximate), this means we divide by 1.609 when converting from km to miles

So,

4,987 km = 4987/(1.609) = 3,099.4406 miles approximately

This rounds to 3099 miles

----------------

You can optionally show your work like this:

[tex]4,987,000 \text{ m} * \frac{1 \text{ km}}{1000 \text{ m}}*\frac{1 \text{ mi}}{1.609 \text{ km}}\\\\ = \frac{4,987,000*1*1}{1000*1.609} \text{ mi} \\\\\approx 3099.4406 \text{ mi}\\\\ \approx \textbf{3099 mi}[/tex]

Notice that the "km" and "m" units cancel out when going from the first step to the second step. All that's left is the "mile" unit.
