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

Answer:

9.8 x 2.2 =  21.56 m

distance = time x speed

speed = distance ÷ time

Step-by-step explanation:

The highest point he reached occurred at the vertex, which is at t = -b/2a = 2.2 second. Plugging in t = 2.2

9.8 x 2.2 =  21.56ft

Higher cliffs don't accelerate your fall -- acceleration is constant during free fall. The pull of gravity decreases infinitesimally at higher elevations, but it pulls you with an equal force from the first second of your jump until you decelerate when you hit the water.

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%.

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%.

The marble was traveling at 4.05 miles per hour.

Since in science class, Antonio and Anna were measuring the approximate speed of a marble as it exits from an 8-foot-long ramp, and they discovered that it took 2.1 seconds for the marble to travel 12.5 feet from the end of the ramp, to determine approximately how fast was the marble traveling as it exited from the ramp to the nearest hundredth of a second, the following calculation must be performed:

Therefore, the marble was traveling at 4.05 miles per hour.

Answer:

£5.41

Step-by-step explanation:

7.25/1.34 = 5.41044...

Round = 5.41

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

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.

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]

Also, if it's wrong please let me know.

Step-by-step explanation:

what is the problem here, what do you not understand ?

you do know fractions, and how to multiply and divide them ? because that would be a precondition for a teacher to give you such a problem to solve.

so, if you do know the handling of fractions, this is very basic and easy thing to solve.

let's get into it then :

2 similar triangles. that means all lengths of all lines in one triangle are the result of multiplying the corresponding lines in the other triangle by a constant factor.

that is the meaning of a scaling factor.

it is like on a map, where it says 1 unit on the map is that many units out there in reality.

your teacher was really nice to point out the right angles and even a second angle (37 degrees), so that we can immediately see, which side or line of one triangle corresponds to which side or line of the other.

when we imagine now to turn e.g. the smaller triangle so that it is oriented the same way as the larger one, we see that QS corresponds to LJ. and QR to LK. and RS to KJ.

so, we are going in the scaling process from left to right. that means we are starting with the larger triangle and turn it into the smaller triangle.

so, what (scaling) factor do I need to multiply with 15 to get 10 ?

it is the same factor to go also from 9 to 6 and from 12 to 8.

15×x = 10

x = 10/15 = 2/3

15 × 2/3 = 30/3 = 10

12 × 2/3 = 24/3 = 8

9 × 2/3 = 18/3 = 6

so, as you can see, 2/3 is the correct scaling factor.

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

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 :

and both the diagnonals of a Rectangle are equal,

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 :

similarly,

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