Find the hypotenuse (c) of the right triangle.

Aleksandr-060686 [28]

<h2>Solution:-</h2>

Hypotenuse (x) of the right triangle = $\sqrt{7² \: + \: 11²}$

Hypotenuse (x) of the right triangle = $\sqrt{49 \: + \: 121}$

Hypotenuse (x) of the right triangle = $\sqrt{170}$

Hypotenuse (x) of the right triangle = 13

The hypotenuse (x) of the right triangle is 13 m.

<h3>Hence, option (D) 13 m is correct. [Answer]</h3>

If there are 37 figures and there are six people how many will each person get

Elis [28]

Answer:

It depends.

Step-by-step explanation:

If we're able to brake the figures, then each person will get six and one sixth of a figure

$37 \div 6 = 6 \frac{1}{6}$

But if we can't break them, then each person will get six figures with one remaining ungiven.

$37 \div 6 = 6 \: (1)$

Find the 91st term of the arithmetic sequence 28, 8, –12, ... Anybody know the answer?

tankabanditka [31]

Answer:

-1772

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as;

Tn = a+(n-1)d

a is the first term

n is the number of terms

d is the common difference

From the sequence

a = 28

d = 8-28 = -12-8 = -20

n =91(since we are looking for the 91st term)

Substrate

T91 = 28+(91-1)(-20)

T91 = 28+90(-20)

T91 = 28-1800

T91 = -1772

Hence the 91st term is -1772
