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:

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

A rectangle has the are of 60 inch2. What can be its dimensions? Copy and fill in the chart.

Answers

Answer:

In order of the blanks from left to right, 30; 6; 2; 1/2; 20; 12; 12; 3/5

Step-by-step explanation:

So the rectangle has an area of 60 inches squared & the equation for the area of a rectangle is width * height. So, you can find the missing term if you just take 60 & divide it by the given number.

60/2 = 30

60/10 = 6

60/30 = 2

60/120 = 1/2

60/3 = 20

60/5 = 12

60/5 = 12

60/100 = 3/5

The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?

Answers

Answer:

[tex]222[/tex] boys

Step-by-step explanation:

Let [tex]x[/tex] = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

[tex]\frac{5}{6+5}x = 185[/tex] (number of girls in ninth grade)

[tex]\frac{5}{11}x = 185[/tex]

[tex]x=407[/tex]

To find for the number of boys, we can use substitution:

[tex]\frac{6}{6+5}x = \frac{6}{11}(407)[/tex]

[tex]=222[/tex]

∴ There are [tex]222[/tex] boys in the class.

y is the total temperature

6x is the increase of temperature by 6° per x hours

30 is the y-intercept, you start with this number

9514 1404 393

Answer:

y = 30 + 6xsee below for a graph

Step-by-step explanation:

The increase in temperature is the product of the increase per hour and the number of hours: 6x.

The temperature at any time is the sum of the initial temperature (30°) and the increase (6x).

  y = 30 + 6x . . . . . temperature equation

This is graphed as a line with an initial value of 30 and a slope of 6. (Note the attached graph has different grid line spacing vertically than horizontally.)
