7 0

Answer:

As you have already selected the answer is 19

Step-by-step explanation:

As for this question you can see that the triangles in the sequence each get incremented by 3 for each term. The first one has 1, the second one has 4, the third one has 7 and so on. So judging by this sequence if this continues to the 7th term you will end up with 16. The second has 4, the third has 7, the fourth has 10, the fifth has 13, and the sixth has 16 and finally you get 19 as your 7th term! I hope this answer helped your question! :)

Write a number with one decimal place,that is bigger than 6 4/5 but smaller than 7 how can I solve this

statuscvo [17]

Hello!

The easiest way to solve this would be to convert 6 4/5 to a decimal. We know that to convert a fraction to a decimal, we must divide the numerator by the denominator.

4 / 5 = 0.8

0.8 + 6 = 6.8

So, 6 4/5 is 6.8 as a decimal.

See how it's easier now that we've converted the mixed number to a decimal?

There could be many numbers between 6.8 and 7. Some examples are:

6.81, 6.82, 6.83, 6.9, etc.

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.

Answer:

AD = 7

Step-by-step explanation:

Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.

We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD

We can solve the problem by solving for x:

$\frac{x}{32} =\frac{21}{24}$
