The sum of three consecutive intergers is 189 what are the integers

Answers

Answer:

  62, 63, 64

Step-by-step explanation:

The middle integer of three consecutive integers will be the average of them. That is, it will be their sum, divided by 3.

__

The middle integer is 189/3 = 63.

The three consecutive integers are 62, 63, 64.

_____

Additional comment

If you'd like to write an equation that tells you the same thing, let x represent the middle integer. Then the lower one is x-1, and the upper one is x+1. Their sum is ...

  (x-1) +x +(x+1) = 189

  3x = 189 . . . . . . . . . . . . simplify

  x = 189/3 = 63 . . . . . . . divide by the coefficient of x

  (x-1) = 63-1 = 62 . . . . . . find the other two integers

  (x+1) = 63+1 = 64

There are 2022 kangaroos and some koalas living across seven parks. in each park the number of kangaroos is equal to the number of koalas in all the other parks. how many koalas live in the seven parks in total

Answers

Answer:

337

Step-by-step explanation:

I remember this from UKMT maths challenge.

Let the number of kangaroos in each of the seven parks be , , , , , and with the

corresponding number of koalas being , , , , , and . The question tells us that the

number of kangaroos in any park is equal to the sum of the numbers of koalas in the other six

parks. Therefore we have

= + + + + + ,

= + + + + + ,

= + + + + + ,

= + + + + + ,

= + + + + + ,

= + + + + + ,

= + + + + + .

Adding these equations, we obtain

+ + + + + + = 6( + + + + + + ).

The total number of kangaroos in the seven parks is 2022. Hence

+ + + + + + = 2022.

Therefore

2022 = 6( + + + + + + )

and hence the total number of koalas in the seven parks is

+ + + + + + = 2022 ÷ 6 = 337.

The density of iron is 7.8 g/cm3. an iron beam has a volume of 10,504 cm³. what is the mass of the iron beam? enter your answer as a decimal in the box.

Answers

Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.

How to determine the mass of the iron beam

Let suppose that the iron beam has an uniform density, the mass of the iron beam (m), in gram, is equal to the product of its density (ρ), in grams per cubic centimeter, and its volume (V), in cubic centimeters:

m = ρ · V     (1)

If we know that ρ = 10504 cm³ and V = 7.8 g/cm³, then the mass of the iron beam is:

m = (7.8 g/cm³) · (10504 cm³)

m = 81931.2 g

Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.

Rita has a circular hot tub. the hot tub has a circumference of 25.12 feet. it is 3.5 feet deep.

how much water can the hot tub hold?

Answers

Volume is a three-dimensional scalar quantity. The amount of water that the tub can hold is 4,981.75 litres.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.


Given the circumference of the tub is 25.12 feet, therefore, the radius of the circumference of the tub will be,

Circumference = 2πr

25.12 = 2×π×r

r = 3.9979ft ≈ 4ft

Now, the volume of the tub will be,

Volume = πr²h = π×(4²)×3.5 = 175.929 ft³

Since 1 ft³ is equal to 28.3168 litres, therefore, the amount of water that a tub can store is

Volume of water = 175 × 28.3168 = 4,981.75 litres

Hence, the amount of water that the tub can hold is 4,981.75 litres.

Which equation is equal to y = 2x + 3 ?
the options are
y + 3 = 2x

y - 3 - 2x = 0

2x + y = 3

y + 2x = -3

Answers

The equation y = 2x + 3 is a linear equation, and the equivalent equation of y = 2x + 3 is y - 3 - 2x = 0

How to determine the equal equation?

The equation is given as:

y = 2x + 3

Subtract 3 from both sides

y - 3 = 2x

Subtract 2x from both sides

y - 3 - 2x = 0

The above means that the equation y - 3 - 2x = 0 is equal to the equation  y = 2x + 3

Hence, the equivalent equation of y = 2x + 3 is y - 3 - 2x = 0

y = 6-3x

Answers

Answer:

  new equation: 2x +1 = 6 -3x

  solution: (x, y) = (1, 3)

Step-by-step explanation:

The Equal Values Method of solving a system of equations has you equate the two expressions that are equal to the same variable or expression. Here, we have two expressions that are equal to y.

equation

The next step is to set them equal to each other:

  2x +1 = 6 -3x

__

solution

This equation can be solved by adding 3x -1 to both sides to get ...

  5x = 5

Then dividing both sides by 5 gives ...

  x = 1

Substituting into either expression for y gives its value:

  y = 2x +1 = 2(1) +1 = 3

The solution to the system is (x, y) = (1, 3).
