It could be a proportion
24:36=42:x
make into fractions
24/36=42/x
2/3=42/x
multiply both sides by 3x
2x=126
divid oth sides by 2
x=63

the other number is 63

24:36=42:63

Hello There Awesome User!

The answer could be 54.

As you can see the relationship between 24 and 36 is 12. You find this out by subtracting 36-24=12. Where as you could add 42 to 12 which equals to 54. So, the answer is 54.

Thanks and have a good day!

Find the scale ratio for the map described below. 1 mm ​(map) equals 500 m ​(actual) The scale ratio is 1 to nothing.
lana66690 [7]

Answer:

1:500000

Step-by-step explanation:

1 mm ​(map) equals 500 m ​(actual) .

Let's convert 500 m to mm.

1m = 1000mm

500m = 500000 mm

So 1mm to 500000mm on a scale is

1:500000

So it's all about converting the metre to million metre then doing the ratio.

In this case we are not to divide anything because it's already in 1.

So it's 1mm on paper then 500000mm on actual.

Thank you

Determine
Luden [163]

Answer:

\mu_{x} = 64, \sigma_{x} = 12.83

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu_{x} = \mu and standard deviation \sigma_{x} = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 64, \sigma = 77, n = 36

So

\mu_{x} = 64, \sigma_{x} = \frac{77}{\sqrt{36}} = 12.83

A local kids play sold 8 adult tickets and 9 child tickets for a total of $205. On day two they sold only 4 adult tickets and 3
Naya [18.7K]

Answer:

The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13

Step-by-step explanation:

Let x be the cost of 1 adult ticket

Let y be the cost of 1 child ticket

Cost of 8 adult tickets = 8x

Cost of 9 child tickets = 9y

We are given that A local kids play sold 8 adult tickets and 9 child tickets for a total of $205

So, 8x+9y=205 ----- 1

Cost of 4 adult tickets = 4x

Cost of 3 child tickets = 3y

We are given that 4 adult tickets and 3 child tickets for a total of $83.

4x+3y=83 ----2

Plot 1 and 2 on graph

8x+9y=205  -- Red line

4x+3y=83  -- Blue line

Intersection point provides the solution

So, Intersection point =(11,13)

So, The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13
