What is the sum of all integers which are not divisible by 5 or 9 between 1 and 100?​

Answers

The sum of all integers which are not divisible by 5 or 9 between 1 and 100 is 3541.

To determine what is the sum of all integers which are not divisible by 5 or 9 between 1 and 100, the following calculation must be performed:

1 + 2 + 3 + .... + 100 = 5050 (5050 - 9 - 18 - 27 - 36 - 45 - 54 - 63 - 72 - 81 - 90 - 99 - 5 - 10 - 15 - 20 - 25 - 30 - 35 - 40 - 50 - 55 - 60 - 65 - 70 - 75 - 80 - 85 - 95 - 100) = X 3541 = X

Therefore, the sum of all integers which are not divisible by 5 or 9 between 1 and 100 is 3541.

It takes 5 builders 3 1/2 hours to build a wall. How many hours will it take for 2 builders to build an identical wall?.

Answers

Answer:

8.75 hours for 2 builders so complete it

Step-by-step explanation:

its right because im smart and i say its right

If it takes 5 builders [tex]3\frac{1}{2}[/tex] hours to build a wall, it will take 2 builders  [tex]8\frac{3}{4}[/tex] hours to build an identical wall

The time taken for 5 builders to build the wall = [tex]3\frac{1}{2}[/tex] hours

The time take for 5 builders to build the wall = 3.5 hours

Time taken for 1 builder to build an identical wall =

5 x  (Time taken for 5 builders to build the wall)

Time taken for 1 builder to build the wall = 5  x  3.5

Time taken for 1 builder to build the wall = 17.5 hours

Time taken for 2 builders to build an identical wall = (Time taken for 1 builder)/2

Time taken for 2 builders to build an identical wall = 17.5/2

Time taken for 2 builders to build an identical wall =  8.75 hours

Time taken for 2 builders to build an identical wall = [tex]8\frac{3}{4}[/tex] hours

A Freight Train Travels 144 miles in 6 hours. How Far will it travel in 15 hours?

_________________

For this problem I will show you 2 methods.

[tex]{\huge{\boxed{\mathbb{METHOD\:ONE}}[/tex]

Cross multiplication, cross multiplication involves algebra to use.

Let x be our answer for this problem. Here is our it would look like

[tex]\frac{6}{144}=\frac{15}{x}[/tex], now we will cross multiply, here is what it'd look like now.

[tex]6x=2160[/tex], then do simple algebra and divide both sides by 6. and then we get [tex]x=360[/tex] miles in 15 hours.

_________________

[tex]{\huge{\boxed{\mathbb{METHOD\:TWO}}[/tex]

For method two we can look for the unit rate. Also known as our rate for one.

divide 144 by 6 and we get 24, then multiply it by 15 and we get 360.

_________________

[tex]{\huge{\boxed{\mathbb{EXACT\:ANSWER}}[/tex]

Answer:

  ∠J = 60°

Step-by-step explanation:

The Law of Cosines tells you ...

  j² = k² +l² -2kl·cos(J)

Solving for J gives ...

  J = arccos((k² +l² -j²)/(2kl))

  J = arccos((14² +80² -74²)/(2·14·80)) = arccos(1120/2240) = arccos(1/2)

solutions of the quadratic $x^2 + 7x - 18 = 0.$

Answers


(x^2+7x-18) can be factored into (x+9)(x-2). Set each part equal to zero and solve for x.

x+9=0 => x=-9
x-2=0 => x=2

I’m guessing the dollar signs aren’t supposed to be there.

The solution of the quadratic equation x² + 7x - 18 = 0 will be 2 and negative 9.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.

The quadratic equation is given below.

x² + 7x - 18 = 0

Factorize the quadratic equation, then we have

x² + 7x - 18 = 0

x² + 9x - 2x - 18 = 0

x(x + 9) - 2(x - 9) = 0

(x + 9)(x - 2) = 0

x = 2, -9

The arrangement of the quadratic condition x² + 7x - 18 = 0 will be 2 and negative 9.

Answers

Linear functions are represented by constant rates.

The true statement is (d) No, because the amount owed does not change by 2.25 every time the miles change by 1.

From the table, we can see that:

As the number of miles increase by 1, the amount owed increases, but it does not increase at a constant rate of 2.25.

This means that, the table does not represent a linear function.
