The length of the leg of right isosceles triangle is a. Find the length of the hypotenuse.

1 answer:

6 0

A right isosceles triangle has two 45 degree angles. This means the side lengths are the same, so if one leg is a, the other leg is also a.

The hypotenuse of an isosceles triangle is the length os a leg multiplied by the square root of 2.

The hypotenuse would be: a√2

Simplify the expression below. (2n/6n+4)(3n+2/3n-2)

andrezito [222]

Answer:

$\frac{n}{3n-2}$

Step-by-step explanation:

Given the expression:

$\frac{2n}{(6n+4)} \cdot \frac{3n+2}{3n-2}$

Using the distributive property: $a \cdot (b+c) =a\cdot b+a\cdot c$

$\frac{2n}{2(3n+2)} \cdot \frac{3n+2}{3n-2}$

Simplify:

$\frac{2n}{2} \cdot \frac{1}{3n-2}$

Simplify:

$\frac{n}{3n-2}$

Therefore, the simplified given expression is, $\frac{n}{3n-2}$

Seventy percent of the 100 students in middle school cafeteria bought their lunch sone of the students that brought there own lu

gogolik [260]

So we solve for each
70% of 100=70
students who didn't buy lunch=100-70=30

some of the 70 left so that the students who bought lunch, are 60% of those who are left
we know that the students who didn't buy lunch didn't change number so therefor
100% of students left-60%=40%= students that didn't buy lunch=30 so
40%=30
20%=15
100%=75
there were 75 students lfet in the cafeteria
