18th term is 52

19th term is 55

Meaning that the 20th term is 58

Answer:

a₂₀ = 58

Step-by-step explanation:

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 1 and d = a₂ - a₁ = 4 - 1 = 3 , then

a₂₀ = 1 + (19 × 3) = 1 + 57 = 58

There are 210 ways to write 5 of the letters of the word ALGORITHM in a row if the 2 two letters must be TH

Given data

the word ALGORITHM

the first two letters must be TH

ALGORITHM has 9 letters and order of writing the letters is important, so we use Permutation to solve this

The 2 letters TH are fixed and this reduces the number of letters in the word from 9 to 7. Also, the the first two being fixed reduces the letters arrangement to be 3.

This means that we have the arrangement as follows:

7P3

= 7! / ( 7 - 3 )!

= 7! / 4!

= 7 * 6 * 5 * 4! / 4!

= 7 * 6 * 5

= 210 ways

Hence there are 210 ways to write 5 of the letters of the word ALGORITHM in a row if the 2 two letters must be TH

Ilhan's average speed in the race is 11.03 miles per hour.

The average speed is a scalar measure of the total distance divided by the total time.

The average speed shows an object's displacement rate from one point to another.

Speed measures the rate of fastness, while the average speed shows the average rate of fastness of an object in movement.

The average speed is measured in magnitude without direction as a scalar quantity.

Beginning time for the race = 7:22 am

Ending time for the race = 8:07 pm

Time used = 12hours 45 minutes or 12.75 hours (8:07 pm - 7:22 am)

Swimming 2.4 miles

Cycling 112 miles

Running 26.2 mile

Total distance = 140.6 miles

Step-by-step explanation:

The length and width of the rectangle is 46 feet and 10 feet respectively.

Let the length of the rectangle be x and the width of the rectangle be y.

Now, the length of the rectangle is 4 less than 5 times its width.

Therefore,

x = 5y - 4

The perimeter of a rectangle is given as two times the sum of its length and breadth.

Perimeter = 2( length + breadth)

P = 2( x + y)

Now, the perimeter of the rectangle is 112 square feet.

Therefore,

112 = 2( 5y - 4 + y)

( 112 /2) = 5y - 4 + y

6y - 4 = 56

6y = 56 + 4

6y = 60

y = ( 60 / 6)

y = 10

Now,

x = 5y - 4

x = 5 × 10 - 4

x = 50 - 4

x = 46

So, the length of the rectangle is x = 46 feet and the breadth of the rectangle is y = 10 feet.

Step-by-step explanation:

Rate x Time = jobs

Mr. Comb's rate is 1 field in 5 hours or 1/5.

Mr. Ramset's rate is 1 fiend in 4.5 hours.

If we take the time and rate that it takes Mr. Comb's to mow one field and add it to the time and rate that it takes Mr. Ramset's to move one field  we can find out how long it takes them to mow one field together

RT + RT = 1 (job)

1/5T + 1/4.5T = 1  We need a common denominator.  I just multiplied 5 x 4.5  for get 22.5  Rewrite 1/5 and 1/4.5 with a common denominator or 22.5 we get the equivalent fractions that we can add together.

4.5/ 22.5T + 5/22.5T = 1  Add the fractions together

9.5/22.5T = 1  We want to solve for T, so we will multiply both sides of the equation by 22.5/9.5

9.5/22.5(22.5/9.5)T= 1 22.5/9.5

T = 22.5/9.5  When I divide these, I get 2 35/95 hours.  I need to change the fraction part of an hour to minutes.  I will use the unit multiplies 60 minutes/ 1 hour.

35hours/95 (60 minutes/1 Hour) = 22.10526331579.  I need to round this to the nearest minutes which will be 22 minutes.
