The length of LN in the triangle below is (LN)²=33²-11². It is obtained by applying the pythogorous theorem in the triangle MLN. Option A is correct,

<h3>What is the definition of a right-angle triangle?</h3>

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometric function.

According to Pythagoras, the sum of the squares of two sides equals the square of the longest side.

In triangle MLN applies the pythogorous theorem;

\rm h^2=p^2+b^2 \\\\ MN^2=ML^2+LN^2 \\\\ 33^2=11^2+LN^2 \\\\ LN^2=33^2-11^2

Hence option A is correct.

A tube feeding formula contains 6 grams of protein per each 80 ml of the formula. If the patient needs 120 grams of protein per
Anit [1.1K]

Answer:

1600 ml.

Step-by-step explanation:

Let x represent amount of tube-feeding formula.

We have been given that a tube feeding formula contains 6 grams of protein per each 80 ml of the formula.

To solve our given problem, we will use proportions as:

\frac{x}{\text{120 gram}}=\frac{\text{80 ml}}{\text{ 6 grams}}

\frac{x}{\text{120 gram}}*\text{120 gram}=\frac{\text{80 ml}}{\text{ 6 grams}}*\text{120 gram}

x=\text{80 ml}*20

x=\text{1600 ml}

Therefore, the patient should get 1600 ml of tube feeding formula every day.

densk [106]

Answer:  There are 177100 possible groups.

Step-by-step explanation:

Given: Total employees = 25

Number of  employees  wants to choose = 6

The combination of n things taken r at a time is given by:-

^nC_r=\frac{n!}{r!(n-r)!}

Put n = 25 and r= 6, we get

^{25}C_6=\frac{25!}{6!(25-6)!}\\\\=\frac{25\times24\times23\times22\times21\times20\times19!}{6!19!}\\\\=177100

Hence, there are 177100 possible groups.
