Answer:

27 days

Step-by-step explanation:

A alone, rate per day = 1/36

A and B together, rate per day = 1 / 20

Total Workdone for 5 days :

1/ 20 * 5 = 5 / 20 = 1/4

Fraction of work left :

1 - 1/4 = 3/4

3 / 4 * 36 /1

= (3 * 36) / 4

= 108 / 4

= 27 days

Answer:

If these are answer choices, i believe the correct answer is B, time.

Answer:

74

Step-by-step explanation:

13 5-peso coins

9 1 peso coins

13 X 5 = 65

9 X 1 = 9

65+9 = 74

Answer:

If t= 6

3 (2 x 6 + 5) 6 x 6 + 15

3 (12+5) 36 + 15

3 x 17 =51

= 51

The value of both expressions when t=6 is 51

When t = 3

3(2 x 3 + 5) 6 x 3 + 15

3 (6 +5) 18 + 15

3 x 11 =33

= 33

The value of both expressions when t= 3 is 33

Answer:

slope = 2, y- intercept = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4 + 2x , that is

y = 2x - 4 ← is in slope- intercept form

with slope m = 2 and y- intercept c = - 4

Answer: 1/125cm³

Step-by-step explanation:

The volume of a cube is gotten by multiplying the side length given by itself thrice.

Since the cube in the question has a side length of 1/5cm, the volume of the cube will be:

= 1/5 × 1/5 × 1/5

= 1/125cm³

Therefore, the volume of the cube is 1/125cm³

Answer:

x1 = 2, x2 =-8

y1=-2, y2 =-2

y2-y1 = |-2+2| =0

x2-x1= |-8-2|= 10

So distance is 10 units

Answer:

36/11

Step-by-step explanation:

Answer:

36/15

Step-by-step explanation:

==========================================================

Explanation:

To get this answer, we double the 71.40 to get 142.80

You can think of it like an equation and we multiply both sides by 2

4 jeans = 71.40 dollars

2*(4 jeans) = 2*(71.40 dollars)

8 jeans = 142.80 dollars

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

Or you could solve it like this

(4 jeans)/(71.40 dollars) = (8 jeans)/(x dollars)

4/71.40 = 8/x

4x = 71.40*8

4x = 571.2

x = 571.2/4

x = 142.80

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

Yet another way to solve is to first find the unit rate

4 jeans cost 71.40, so that must mean 1 pair of jeans cost 71.40/4 = 17.85 dollars. This is the unit rate since "unit" means "one". It's the price per pair of jeans.

Multiply that by 8 to find out how much 8 pairs will cost, and we get 17.85*8 = 142.80

Card 1= 20

Card 2= nOt sure

Card 3=28

Card 4= 40

Teléfonos móviles :

Universo - -> {todos los teléfonos móviles} - unidad experimental

Población - -> {Samsung, tecno, LG, iPhone, Motorola, Huawei, .....} - -> valores variables de unidades experimentales

Muestra - - -> {Samsung, tecno, iPhone} - selección aleatoria de datos de población

Países europeos :

Universo - -> {todos europeos} - unidad experimental

Población - -> {Inglaterra, Noruega, Turquía, Italia, Francia, Holanda, .....} - -> valores variables de todos los países europeos

Muestra - - -> {España, Alemania, Polonia} - selección aleatoria a partir de datos de población

Explicación paso a paso:

Haciendo distinción entre universo, población y muestra. Univerae y la población se describen como sinónimos en algún texto. Sin embargo, otros textos estadísticos hicieron diferencias sutiles entre ambos; con el universo que se dice que contiene todas las unidades experimentales. ; siendo población el conjunto de valores de la variable. Sin embargo, podemos asumir de manera concluyente que ambos son sinónimos, ya que de ellos se extrae una muestra que es un subconjunto de un conjunto de datos más grande (población).

Answer:

54.5%

Step-by-step explanation:

Given data

Cost price= $15

Selling price= $33

Mark up percent =????

%markup= selling-cost/selling*100

substitute

%markup= 33-15/33*100

%markup= 18/33*100

%markup=0.545*100

%markup= 54.5%

Hence the Percent markup is 54.5%
