Visitors to a cinema are either children, adults or pensioners the ratio of children to adult visitors is 1 : 2 the ratio of adults to pensioners is 3 : 4 a stratified sample is to be taken from the cinema visitors how many pensioners should be in the sample?

Answers

Answer 1

Answer:

the number of pensioners in the sample is 40

Step-by-step explanation:

The computation of the number of pensioners in the sample is shown below:

Given that

The Ratio of children to adult visitors is 1:2

The ratio of adults to pensioners is 3:4

And, the total number of seats is 85

Based on the above information,

The common ratios we could write as

1.5 : 3 : 4

Now we doubled it

3 : 6 : 8

So, the number of pensioners in the sample is

= 85 × 8 ÷ (3 + 6 +8)

= 40

Hence, the number of pensioners in the sample is 40

Answers

Answer:

The answer is 9 (B)

Step-by-step explanation:

I got 9 because you have to plug in answer (7, 9, 11, 8) in each equation than add them both together. I first plugged in 7 for x in the equation 9x-5. I got 58. I plugged in 7 for x in the equation 5x+12 and got 47. When I added both the answers together I got 105. The answer was to low because SU has to be 133. I plugged in 9 for x in both equations then added them both and got 133 for SU. I hope this helps.

George purchased a concert ticket on a web site. The original price of
the ticket was $85. He used a coupon code to receive a 15% discount.
The website applied a 10% service fee to the discounted price. George's
ticket was less that the original price by what percent?
15%
10%
6.5%
8.5%

Answers

Answer:

6.5%

Step-by-step explanation:

The original price of the ticket was 100% of the price of the ticket.

The 15% coupe reduced the price to 85% of the price of the ticket.

The 10% fee on the discounted price adds 10% of 85% to 85%, so it adds 8.5% to 85%. By adding the fee he is at 93.5% of the original price.

100% - 93.5% = 6.5%

The overall percent off compared to the original price was 6.5%.

Fahim is 6 feet tall. At noon, he stands with the sun behind him casting a shadow. The distance from the top of Fahim's head to the furthest tip of the shadow is 13 feet. A right triangle with side length 6 feet, s, and hypotenuse 13 feet. [Not drawn to scale] What is the length of Fahim's shadow? Round to the nearest tenth of a foot. 7.0 feet 8.5 feet 11.5 feet 14.3 feet

Answers

Answer: 11.5 feet

Step-by-step explanation:

We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:

Let the length of Fahims shadow be x

hypotenuse² = opposite² + adjacent ²

13² = 6² + x²

169 = 36 + x²

x² = 169 - 36

x² = 133

x =✓133

x = 11.53

= 11.5 feet to nearest tenth

11.5 feet

Olivia took out 8 glasses and poured juice from the pitcher. The capacity of each

there?

Answers

1.8 Liters

olivia took out 8 glasses and poured juice from the pitcher.

The capacity of each glass is 3/10 liter.

If there was enough juice for 6 glasses.

This means that the amount of juice will be the total quantity of juice poured in 6 glasses.

Since, capacity of 1 glass= 3/10 liters=0.3 liters

Capacity of 6 glasses= 6×0.3=1.8 liters.

classify the equation 6(x+2)=5(x+7) as having one solution, no solution, or infinitely many solutions.

Answers

The equation has one solution.


6(x+2)=5(x+7)
6x+12=5x+35
6x+12-5x=35
6x-5x=35-12
x=23
Therefore, the equation has ONE solution.

The equation 6x + 12 = 5x + 35 will have one possible solution i.e. (23, 150)

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the following equation as -

6x + 12 = 5x + 35

Assume that -

6x + 12 = 5x + 35 = y

y = 6x + 12

y = 5x + 35

Graph the equations. The points of intersection would be the solutions.

Therefore, the equation 6x + 12 = 5x + 35 will have one possible solution i.e. (23, 150)

Metro cable tv tuvo ventas de 2500000 en su primer año de funcionamiento. Si a partir de entonces las ventas aumentaron 12% con respecto al año anterior, calcule las ventas de la empresa en el quinto año y las ventas totales durante los primeros 5 años de operación

Answers

Explicación paso a paso:

Dado

Principal = 2,500,000

Tasa = 12% (anual)

tiempo = 5 años

Incremento después del primer año = 12% de 2.500.000

= 12/100 * 2,500,000

= 12 * 25000

= 300.000

El monto al final de los 5 años se calculará utilizando la fórmula de interés compuesto;

A = P (1 + r) ^ n

A = 2500000 (1 + 0,12) ^ 5

A = 2500000 (1,12) ^ 5

A = 2500000 (1,7623)

A = 4.405.854,208

Por lo tanto, las ventas totales durante los primeros 5 años de operación son 4.405.854,208

Obtenga la cantidad obtenida en el quinto año

El monto al final de los 4 años se calculará utilizando la fórmula de interés compuesto;

A = P (1 + r) ^ n

A = 2500000 (1 + 0,12) ^ 4

A = 2500000 (1,12) ^ 4

A = 2500000 (1,5735)

A = 3.933.798,4

Utilidad obtenida en el quinto año = 4.405.854,208 - 3.933.798,4

A = 4.405.854,208 - 3.933.798,4

A = 472.055,808

Por lo tanto, la ganancia obtenida en el quinto año es de 472,055.808

Monto realizado en el quinto año = Principal + intereses en el quinto año

Monto realizado en el quinto año = 2500000 + 472,055.808

Monto realizado en el quinto año = 2,972,055.808

Four tenths of a number increased by the second number equals 19. One tenth of the first number decreased by the second number is equal to 1. What are the two numbers?

Answers

Answer:

The two numbers are 40 and 3

Step-by-step explanation:

Assume that the first number is x and the second number is y

Four tenths = [tex]\frac{4}{10}[/tex] = 0.4

One tenth = [tex]\frac{1}{10}[/tex] = 0.1

∵ Four tenths of 1st number increased by the 2nd number equals 19

∵ The 1st number = x and the 2nd number = y

0.4x + y = 19 ⇒ (1)

∵ One tenth of the 1st number decreased by the 2nd number is equal to 1

0.1x - y = 1 ⇒ (2)

Now we have a system of equations to solve it

→ Add equations (1) and (2) to eliminate y

(0.4x + 0.1x) + (y + -y) = (19 + 1)

∴ 0.5x + 0 = 20

∴ 0.5x = 20

→ Divide both sides by 0.5 to find x

∵ [tex]\frac{0.5x}{0.5}[/tex] = [tex]\frac{20}{0.5}[/tex]

x = 40

→ Substitute the value of x in equation (1) or (2) to find y

0.4(40) + y = 19

∴ 16 + y = 19

→ Subtract 16 from both sides

∴ 16 - 16 + y = 19 - 16

y = 3

The two numbers are 40 and 3
