Answer:

8/25 = 32/100
7/20 = 35/100

Step-by-step explanation:

25 and 20 have a least common multiple of 100, so that is your least common denominator.

8/25 = (8·4)/(25·4) = 32/100

7/20 = (7·5)/(20·5) = 35/100

PLEASE HELP ME RN PLEASE

Advocard [28]

Answer:

$\frac{n^{2} - 1 }{2}$

$\sqrt{29}$

Step-by-step explanation:

Area of triangle=1/2×b×h

$\frac{1}{2} \times (n - 1)(n + 1)$

$\frac{( {n}^{2} + n - n - 1) }{2 }$

$\frac{ {n}^{2} - 1 }{2}$

2. Area of triangle=14

$\frac{ {n}^{2} - 1 }{2} = 14$

${n}^{2} - 1 = 28$

${n}^{2} = 29$

$n = \sqrt{29}$

What is the power of 15<br> ------------------

miv72 [106K]

Answer:

If something is "to the power of 15" then it means it is multiplied by itself 14 times (one less than 15 as the original number is already to the power of 1).

An example:

So 2 to the power of 15, which we write as 215 = 2 * 2 * 2 * 2 etc... (so we have 15 written 2's in total meaning we will make 14 multiplications) is equal to 32,768.

4. Is it possible to have a triangle with the sides 6.1 cm, 3.2cm, 2.4cm? Justify your reason with suitable reason.

Dahasolnce [82]

Answer: No
Explanation: There is a rule that stays that a triangle's 2 least sides must add up to be greater than the biggest side. 3.2 plus 2.4 is not greater than 6.1.
