Answer 1

Answer:

  16x -2

Step-by-step explanation:

You know how to compute the perimeter of a rectangle of length L and width W:

  P = 2(L+W)

Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.

  P = 2((5x-2) +(3x+1))

  P = 2(8x -1)

  P = 16x -2 . . . the perimeter of the rectangle

Alexander was given a gift card for a coffee shop. Each morning, Alexander uses the card to buy one cup of coffee. Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance. Write an equation for A,A, in terms of x,x, representing the amount money remaining on the card after buying xx cups of coffee.

Answers

Answer: [tex]A = 15 - 4x[/tex] .

Step-by-step explanation:

Total amount remaining = Initial amount in the card-( Cost per cup × (Number of cups) )

Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance.

i.e.  9 = Initial amount in card - (1.50 × 4)

⇒  9 = Initial amount in card - (6)

⇒  Initial amount in card = 9+-6 =15

⇒  Initial amount in card = $15

Let A be the amount money remaining on the card after buying x cups of coffee.

So,  A = 15 - 4x

Hence, the required equation is [tex]A = 15 - 4x[/tex] .

Answer:

A= -1.50x+15

En un colegio hay 627 alumnos y sabemos que hay el doble de chicas que de chicos. De las chicas, a todas menos a 15, les gustan mucho las matemáticas. ¿Cuántas chicas disfrutan con las matemáticas en este colegio?

Answers

Answer:

Hay 403 chicas que disfrutan las matemáticas en este colegio.

Step-by-step explanation:

Podemos obtener las siguientes pistas tras una lectura cuidadosa del enunciado:

1) Existen 627 alumnos entre hombres y mujeres en el colegio.

2) La cantidad de chicas es el duplo de la cantidad de chicos.

3) Solo a 15 chicas les disgusta las matemáticas.

Matemáticamente hablando, podemos construir las siguientes tres fórmulas:

[tex]x+y = 627[/tex] (1)

[tex]y = 2\cdot x[/tex] (2)

[tex]m = y - 15[/tex] (3)

Donde:

[tex]x[/tex] - Cantidad de chicos en el colegio, adimensional.

[tex]y[/tex] - Cantidad de chicas en el colegio, adimensional.

[tex]m[/tex] - Cantidad de chicas que disfrutan de las matemáticas en el colegio, adimensional.

Al eliminarse [tex]y[/tex] en (1), se puede hallar la cantidad de chicos en el colegio:

[tex]x + 2\cdot x = 627[/tex]

[tex]3\cdot x = 627[/tex]

[tex]x = 209[/tex]

Hay 209 chicos en el colegio.

Por (2) podemos determinar la cantidad de chicas:

[tex]y = 2\cdot (209)[/tex]

[tex]y = 418[/tex]

Hay 418 chicas en el colegio.

Finalmente, se calcula la cantidad de chicas del colegio que disfrutan las matemáticas por (3):

[tex]m = 418-15[/tex]

[tex]m = 403[/tex]

Hay 403 chicas que disfrutan las matemáticas en este colegio.

Where B is the base and H is the height of the right triangle.

The distance between the points P and Q will be 4 units.

If the ordinate of the point is (a, 3) or (b, -1). Then the area of the triangle will be 4 square units.

The point is the remaining vertex of a triangle with an area of 4 square units will be S(-2, -1).

Then the correct option is B.

The perimeter of the circle with an area of 32 π square units is 2√32π units.

Given,

The area of a circle is 32 π square units.

We need to find its perimeter.

What is the area of a circle?

The area of a circle is given by:

= π r²

The perimeter of a circle is given by:

= 2πr

Where r = radius

Find the area of a circle.

Area = π r²

32 π  = π r²

Divide both sides by π

32 = r²

r = ±√32

r can not be negative so we have,

r = √32

Find the perimeter of a circle.

P = 2πr

P = 2 x π x √32

P = 2√32 π units

The perimeter of the circle with an area of 32 π square units is 2√32π units.

Solve for X in the following proportion: 6/33 = 24/x

Answers

Answer:

132

Step-by-step explanation:

We are given the equation 6/33 = 24/x. We would like to solve for x.

To get rid of the fractions, let's multiply both sides by 33x:

(6/33) * 33x = (24/x) * 33x

6x = 24 * 33 = 792

Divide by 6 from both sides:

x = 792/6 = 132

Thus, x = 132.

The sum of an arithmeit cprogression consisting of 20 positive integer terms with positive common difference is equal to 2020. (a) how many progressions are possible (b) what are the smallest and largest possble values of the first term?

Answers

Answer:

a) possible progressions are 5

b) the smallest and largest possible values of the first term are 16 and 82

Step-by-step explanation:

Sum of terms:

Sₙ = n/2(a₁ + aₙ) = n/2(2a₁ + (n-1)d)S₂₀ = 20/2(2a₁ + 19d) = 10(2a₁ + 19d)2020 = 10(2a₁ + 19d)202 = 2a₁ + 19d

In order a₁ to be an integer, d must be even number, so d = 2k

202 = 2a₁ + 38k101 = a₁ + 19k

Possible values of k= 1,2,3,4,5

k = 1 ⇒ a₁ = 101 - 19 = 82k = 2 ⇒ a₁ = 101 - 38 = 63k = 3 ⇒ a₁ = 101 - 57 = 44k = 4 ⇒ a₁ = 101 - 76 = 25k = 5 ⇒ a₁ = 101 - 95 = 16

As per above,

a) possible progressions are 5b) the smallest and largest possible values of the first term are 16 and 82

A red marble is selected at random from a bag containing 2 blues and 9 red marbles and is not replaced.the probability that a second marble selected will also be red is

Answers

Answer:

 So the probability of drawing a second red marble is 8 out 10 or 0.8.

Step-by-step explanation:

It seems to me that if one red marble is already gone, there are 8 red marbles left out of a total of 10 marbles.

So the probability of drawing a second red marble is 8 out 10 or 0.8.

Answer:

8/10 or 4/5 or 0.8

Step-by-step explanation:

since one red marble is already taken, there are only eight remaining now and the total number of marbles are ten now. So you have to divide.

Therefore, the probability is 8/10 or 4/5 or 0.8.

Carol got $500 for her birthday. She wants to buy some video games and a gaming system. An Xbox 1 costs $278. A new game costs $62. What is the most amount of games Carol can afford?

Answers

Answer:

She can buy 3 games.

Step-by-step explanation:

Giving the following information:

Carol got $500 for her birthday.

Xbox 1= $278

A new game costs $62

First, we need to structure the total cost formula:

Total cost= 278 + 62x

x= number of games

Now, we can isolate x:

500= 278 + 62x

222/62= x

3.58=x

She can buy 3 games.
