The product of two consecutive even positive integers is 674 more than the sum of the two integers. Find the integers.

IrinaVladis [17]

$2n(2n+2)=2n+2n+2+674\\
4n^2+4n=4n+676\\
4n^2=676\\
n^2=169\\
n=-13 \vee n=13$
$-13\not\ \textgreater \ 0$

$n=13\\
2n=26\\
2n+2=28$

It's 26 and 28.

Find the height of a right circular cone if the slant height is 4 units and the radius is 2 units

k0ka [10]

The slant height of the right circular cone will be $l=2\sqrt5}$

<h3>What is slant height of cone? </h3>

The formula for the slant height of the cone is given as:

$l^2=r^2+h^2$

Here we have

r=2 units

h=4 units

By putting the values we will get

$l=\sqrt{4^2+2^2$

$l=\sqrt{16+4$

$l=\sqrt{20}$

$l=2\sqrt{5}$

Hence the slant height of the right circular cone will be $l=2\sqrt5}$

Rewrite 19/19 as a whole number

Elis [28]

The answer is 1.

Because if you simplify (divide) 19/19 you get one.

4/4 would also be 1. Any number divided to itself will always be 1.

Whereas 30/15 would be 2 because thirty divided by fifteen is 2
