The answer would be 34. The pattern looks like they are adding the sum to the next expression. So 21+5+8=34. Hope I could help!!:-)))

36% of what number is 18?

pantera1 [17]

Say 36% of 100 is 36. so knowing half of 36 is 18, take half of 100, 50.

so 18/50 = 36

The answer is 50.

Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Thre

grigory [225]

Answer:

About $1,178,974

Step-by-step explanation:

Alright, the sequence we have right now is:

500,000 550,000 605,000

We want to find the common ratio, so let's divide 550,000 by 500,000 and see if we get the same value as 605,000 divided by 550,000:

550,000/500,000 = 1.1

605,000/550,000 = 1.1

Now, we know that r = 1.1. We also know the first term is: $a_1$ = 500,000.

We use the explicit rule of a geometric sequence:

$a_n=a_1*r^{n-1}$

Here, we want to find $a_{10}$ , which means that n = 10. We know r and $a_1$ , so we just plug in these values:

$a_{10}=500,000*(1.1)^{10-1}=500,000*(1.1)^{9}$ ≈ $1,178,973.85$ ≈ $1,178,974$

Thus, the answer is about $1,178,974.

Hope this helps!

A car travels 14km in 25mins . Find out how far the car can travel in 5 hours if the speed remains the same ?

jekas [21]

<h3><u>Answer :- </u></h3>

168 km ...

<h3><u>Explanation :- </u></h3>

It is given that the car travels 14km in 25 minutes..

Now , assume that the distance the car travel in 5 hours be x..

Since 1 hour = 60 minutes..
5 hours = 300 minutes ..

• Thus , The two given statements are :-

14km -----------------> 25 minutes..
And, x km -------------> 300 minutes..

The distance travelled by car and the time taken by the car is directly proportional to each other....

$\frac{14}{25} = \frac{x}{300}$

$= x = 168km$

• Hence , Car can travel 168km in 5 hours ..

Hope this helps you :)

A sample of 15 data is as follows: 17, 18, 17, 17, 13, 18, 5, 5, 6, 7, 8, 9, 20, 17, 3. The mode of the data isa)4b)13c)17d)20Co

Degger [83]

The mode of the data of sample with 15 values is c) 17.

The mode of any sample of data can be calculated by finding the number that is present highest number of times. Based on this, we will look for the numbers that are present multiple times in the mentioned sample.

17, 18 and 5 are the three numbers that are present more than once. Now, let's see what is the frequency of each of these numbers.

Frequency of 17 - 4

Frequency of 18 - 2

Frequency of 5 - 2

Thus, the number 17 is present maximum number of times and hence is the mode of the data.
