the length of the hypotenuse of 30 degrees 60 degrees and 90 degrees triangle is 16. whats the perimeter

1 answer:

6 0

The answer you are looking for would be: 
106 
Because to find the perimeter you have to add the sides so 30+60=90+16+106 
Hope that helps!! 
Have a wonderful day!!

If the whole number multiples of 36 that are both more than 36 and less than 36 squared, how many are squares of whole numbers?

seraphim [82]

This is different than the usual questions we get.

We're given a set of some multiples of 36:

$\{ 2\times 36, 3 \times 36, 4 \times 36, ..., 35 \times 36 \}$

We're asked how many of those are perfect squares.

36 is of course already a perfect square, so for the product to be a perfect square the other factor must be as well. So this is equivalent to:

How many perfect squares are there between 2 and 35?

Just listing them, there's $2^2, 3^2, 4^2 \textrm{ and } 5^2$

Answer: 4 squares

Find the difference between (7,-1) and (-8,-9)

NARA [144]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{7}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{-8}~,~\stackrel{y_2}{-9})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[-8-7]^2+[-9-(-1)]^2}\implies d=\sqrt{(-8-7)^2+(-9+1)^2} \\\\\\ d=\sqrt{225+64}\implies d=\sqrt{289}\implies d=17$

Find four consecutive integers such that 8 times the sum of the first and the third is 40 greater than 10 times the fourth

tatuchka [14]

All four consecutive integers will be 9, 10, 11, and 12 and can be found out by high common sense.

<h3>What is the pattern?</h3>

A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.

For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.

Given that,

8 times the sum of the first and the third = 8( 1st + 3rd)

40 greater than 10 times the fourth = 40 + 10(4th)

So,

8( 1st + 3rd) = 40 + 10(4th)

Now if we look right and side then it will come out as any number with the unit placed as 0.

So it means on the left side also the unit place must be 0.

By thinking of 1st + 3rd = 10 /20 because at 45 it will be 40 which is not equal to the right-hand side.

Now by hit and trial method, we need to guess it 20 = 9 + 11

Then

8(9 + 11) = 40 + 10(12)

One equation can never give us three unknowns hence it will be the correct way.

Hence so the four consecutive integers will be 9, 10, 11, and 12.
