Determine from the balanced chemical reaction if the derived mole ratio is correct or incorrect.

It's incorrect. There are 6 moles of NaBr produced for every 3 moles of Na₂S among the reactants (as well as 2 moles of FeBr₃), so the mole ratio of NaBr to Na₂S should be 2 : 1, not 1 : 1.

Svet_ta [14]

Answer:

Solution,

Let,(x1,y1)=(-4,-3)

     (x2,y2)=(3,5)

Using distance formula,

AB=√(x2-x1)²+(y2-y1)²

    =√(3+4)²+(5+3)²

    =√49+64

    =√113 units.

There are between 50 and 60 number of eggs in a basket. When Loza counts by 3's, there are 2 eggs left over. When she counts by
Strike441 [17]

Answer:

The number of eggs in the basket is 56

Step-by-step explanation:

Given as :

Let The number of eggs in the basket = 3x + 5x

When Loza counts 3's , there are 2 eggs left over

I.e , 3 ( x - 2 )

And  When Loza counts 5's , there are 4 eggs left over

I.e 5 ( x - 4 )

∴ 3 x - 6 = 5 x - 20

Or, 20 - 6 = 5 x - 3 x

Or,  14 = 2 x

∴     x = 7

So, the number of eggs = 3 × 7 + 5 × 7

                                        = 21 + 35 = 56

Hence The number of eggs in the basket is 56   Answer

zhannawk [14.2K]

Answer:

The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65

Step-by-step explanation:

Let x be the number of t-shirts and y be the total pay

As we can clearly see in the table that there is a linear relationship between x and y

A linear function is given as:

y = mx+b

Here m is the gradient of the function then

m = \frac{y_2-y_1}{x_2-x_1}

Taking any two pairs of x and y

(1,68) and (2,71)

m = \frac{71-68}{2-1}\\m = 3

Putting in equation

y = 3x+b

Putting a pair (1,68) in the equation to find the value of b

68 = 3(1) + b\\68 = 3+b\\b = 68-3\\b = 65

Putting the value of b

y = 3x+65

Let p(x) be the linear function

Hence,

The linear function is: p(x) = 3x+65
