Answer:

The answer to your question is: 40.8 g of NaN₃

Step-by-step explanation:

NaN₃ mass = ?

nitrogen = 1.2 moles

Equation

2NaN₃ ⇒ 2Na + 3N2

2 moles of NaN₃ ----------------- 3 moles of N₂

x ------------------ 1.2 moles of N₂

x = (1.2 x 2) / 3

x = 2.4/ 3

x = 0.8 moles of NaN₃

MW NaN₃ = 23 + 28

= 51 g

51 g of NaN₃ ----------------- 1 mol

x ----------------- 0.8 mol

x = (0.8 x 51) / 1

x = 40.8 g of NaN₃

A playing field is rectangular with a length of 100 yards and a width of 53 yards, 1 foot. If a player runs diagonally across t

musickatia [10]

First convert yards to feet.

1 yard = 3 feet.

100 x 3 = 300 feet long.

53 x 3 = 159 + 1 = 160 feet wide.

Now use the Pythagorean theorem to find the diagonal.

x^2 = 300^3 + 160^2

x^2 = 90000 + 25600

x^2 = 115600

x = √115600

x = 340 feet

For question 10e I wrote my answer as t=19, is that correct?

garri49 [273]

Answer:

1/19

Step-by-step explanation:

3(7) -2 = 19, this would be g(7) but they want g^-1 (7) so you need the inverse of your answer:

Cna i get some help with dis plz

Let $b_1,b_2,\ldots,b_{20}$ be the 20 marks of the boys, and $g_1,g_2,\ldots,g_{10}$ be the 10 marks of the girls.

We know that the global mean was 70, meaning that

$\dfrac{b_1+b_2+\ldots+b_{20}+g_1+g_2+\ldots+g_{10}}{30}=70$

Multiplying both sides by 30 we deduce that the sum of the scores of the whole classroom is

$b_1+b_2+\ldots+b_{20}+g_1+g_2+\ldots+g_{10}=2100$

By the same logic, we work with the marks of the boys alone: we know the average:

$\dfrac{b_1+b_2+\ldots+b_{20}}{20}=62$

And we deduce the sum of the marks for the boys:

$b_1+b_2+\ldots+b_{20}=1240$

Which implies that the sum of the marks of the girls is $2100-1240=860$

And finally, the mean for the girls alone is

$\dfrac{860}{10}=86$

What is 2/3 divided by 3/4

ad-work [718]

Answer:

8/9

Step-by-step explanation:

It can sometimes be difficult to divide fractions, such as 2/3 divided by 3/4! When we divide two fractions, such as 2/3 ÷ 3/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other. We also simplify the answers to fraction problems whenever possible.
