Find the sum of the counting numbers from 1 to 25 inclusive. In other words, if S = 1 + 2 + 3 + ... + 24 + 25, find the value of S.

Answers

Answer:

325

Step-by-step explanation:

You must have heard about Arithmetic Progressions (AP)

Arithmetic progressions are a series of numbers such that every successive number is the sum of a constant number and the previous number.

Our very own counting numbers form AP

For example :-

2 = 1 + 1

3 = 2 + 1

4 = 3 + 1

The number in bold (1) is that constant number which is added to a number to form its successive number.

To find the sum of series forming AP, we use the formula :-

[tex]sum = \frac{n}{2} \{ a + a _{n} \} [/tex]

here,

n is the number of termsa is the first number of the series an is the last number of the series

So we'll use all this information to find the sum of continuous numbers from 1 to 25 where 1 is the first term(a) and 25 is the last(an).

and n is 25

[tex]S = \frac{25}{2}\{ 1 +25\} [/tex]

[tex] = \frac{25 \times 26}{2} [/tex]

[tex] = 25 \times 13[/tex]

[tex] = 325[/tex]

So, the value of S comes out to be 325.

Answer:

s= 325

Step by step explanation:

Add all numbers 1 to 25 to get 325.

Neelam’s team had a mean score of 150 in the 4 games his team played this season. Alanoud’s team had a mean score of 80 in the 6 games her team played. What is the mean score for all 10 games played?

Answers

Answer:

115

Step-by-step explanation:

The mean score for all 10 games played is 108 if Neelam’s team had a mean score of 150 in the 4 games his team played this season.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have:

Neelam’s team had a mean score of 150 in the 4 games his team played this season.

Total score(Neelam's team) = 150×4 = 600

Total score(Alanoud’s team) = 80×6 = 480

Total scores = 600 + 480 = 1080

Mean score for all 10 games:

= 1080/10

= 108

Thus, the mean score for all 10 games played is 108 if Neelam’s team had a mean score of 150 in the 4 games his team played this season.

Answer:

f(x)5.79(3)^2 for task 1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Task 1:

Non linear systems of equations:

x + y = 1 -------------------(I)     {Linear equation}

     y =  1 - x

y = x² - 5 ---------------(II)   {Quadratic equation}

Substitute y =1 - x in equation (II)

(II) -->   1 -x = x² -5

Add 'x' to both sides

1 = x² + x - 5

0 = x² + x - 5 - 1   {Subtract 1 from both sides}

x² + x - 6 = 0

x² + 3x - 2x - 6 = 0    {Rewrite the middle term}

x( x + 3) - 2(x + 3) = 0    

(x + 3)(x - 2) = 0

x + 3 = 0       ;  x - 2 = 0

x = - 3   ; x = 2

When x =  - 3 ,   y = 1 -(-3 )

                              = 1 + 3

                             y = 4

When x = 2  ; y = 1 - 2 = -1

Solution of the equations:  (-3,4)  & ( 2,-1)

Task 2:

Part 1: x = 40   ; y = 30

(x - y)² = x² - 2xy + y²

(40 - 30)² = 40² - 2*40*30 + 30²

               = 1600 - 2400 + 900

               = 2500 - 2400

                = 100

Part 2:

a = 10 , b = 11

a³ + b³ = (a + b)(a² - ab +b²)

(10)³ + (11)³ = (10 +11)(10² -10*11 + 11² )

              = 21* (100 - 110 + 121)

              = 21 * ( 221 - 110)

              = 21 * 111

              = 2331

             

A 1400-seat theater sells two types of tickets for a concert. Premium seats sell for $30 each and regular seats sell for $20 each. At one event $33,950 was collected in ticket sales with 10 seats left unsold. How many of each type of ticket was sold?

Answers

Answer:

x = 638

y = 1190 - 638 = 552

Step-by-step explanation:

Let x = premium seats

let y = regular seats

x + y = 1190         (ten were not sold

30x + 20y = 30180    (amount collected

now multiply the first equation by 20 and subtract

20x + 20y = 23800

30x + 20y = 30180

-10x = -6380

x = 638

y = 1190 - 638 = 552

check it by multipying x and y by their price to see if you come up with the correct amount

Hope this helps

premium seats sold : 638
Regular seats sold: 552

Johnny rode his bicycle down a hill. It took him 15 seconds to ride from the top of the hill to the bottom of the hill. The equation h = -3t + 45 models his height, h, in feet, above the bottom of the hill as a function of the time, t, in seconds, after he started riding down the hill. Part A: What is the average rate of change in Johnny’s height? Part B: What is the height of the hill? Part C: How long will it take Johnny to travel 1/3 of the distance down the hill?

Answers

From the height function, we get that:

a) The average rate of change is of -3 feet per second.

b) The height of the hill is of 45 feet.

c) It will take Johnny 5 seconds to travel 1/3 of the distance down the hill.

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

The height, after t seconds, is given by:

[tex]h(t) = -3t + 45[/tex]

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

The height of the hill is [tex]h(t)[/tex] when [tex]t = 0[/tex], thus [tex]h(0) = -3(0) + 45 = 45[/tex]. 45 feet, which means that the the answer for option B is 45 feet.

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

Item a:

The initial height is of 45 feet, at [tex]t = 0[/tex] seconds.The final height is of 0 feet, at [tex]t = 15[/tex] seconds.Thus, the average rate of change is given by:

[tex]A = \frac{0 - 45}{15 - 0} = -\frac{45}{15} = -3[/tex]

The average rate of change is of -3 feet per second.

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

Item c:

One-third of the distance of 45 feet is [tex]\frac{1}{3}45 = 15[/tex] feet, thus, we have to find the time at which he is at 30 feet, that is, t for which [tex]h(t) = 30[/tex]

[tex]h(t) = -3t + 45[/tex]

[tex]30 = -3t + 45[/tex]

[tex]3t = 15[/tex]

[tex]t = \frac{15}{3}[/tex]

[tex]t = 5[/tex]

It will take Johnny 5 seconds to travel 1/3 of the distance down the hill.

2010 $1350


A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.

Answers

$1350-$750=$600
2010-2000=10 years
600/10=$60 increase per year
a) since elliot started with $750 in 2000 and he started working in 2000 that would be his initial fee and every year he increased his fee by $60.
b) y=60x+750

Answer:

Rate of Change: $60 Per year

Step-by-step explanation:

We can find how many years are from 2000 to 2010 not overcouting. That is 10. Now, we do 1350 minus 750 because that's the change of the fee. That will give you 600. Now, 600 divided by 10, giving you how much change each year. That's 60.

So,

2000:750

2001:810

2002:870

2003:930

2004:990

2005:1050

Answers

Answer:

65%×80=52

(80-52=28) no of classmates who liked sports

75%×64=48

(64-48=16) no of relatives who liked sports

no of classmates who liked sports - no of relatives who liked sports

= 28-16 = 12

Hence, 12 more of her classmates like sports as compared to her relatives

There are total 4 more of her classmates like sports as compared to her relatives.

What is the Percentage?

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the information given in the question,

Total number of students surveyed = 80

Percentage of students who like sports = 75%

So,

(80 × 65)/100

= 5200/100 = 52

Total number of Relatives = 64

Percentage of relatives who like sports = 75%

So,

(64 × 75)/100

= 4800/100 = 48

Then, the number more of her classmates like sports compared to relatives will be:

52 - 48

= 4

3. you would then divide 9.50 by 179.50

4. therefore the tax rate would be 0.05 or 5%

The sales tax rate = 5.29%

What is the formula for tax rate?

"Tax rate = (Tax amount / Price before tax) × 100% "

What is the formula for tax amount?

"Tax amount = Final price - Price before tax"

For given question,

Olivia pays $189 for a painting, including tax.

⇒ Final price = $189

The actual price of the painting is $179.50

⇒ Price before tax = $179.50

Using the formula of tax amount,

Tax amount = Final price - Price before tax

Tax amount = 189 - 179.50

Tax amount = 9.5

Now we find the sales tax rate.

Using the formula of tax rate,

Tax rate = (Tax amount ÷ Price before tax) × 100%

Tax rate = [tex]\frac{9.5}{179.50} \times 100~\%[/tex]
