Answer:

240 teachers

Step-by-step explanation:

Let u be 1 unit.

1u+12u=260

13u=260

u=260÷13

=20

No. of teachers=12u=20×12

=240

Let teacher be x

Student=12x

$\\ \sf\longmapsto x+12x=260$

$\\ \sf\longmapsto 13x=260$

$\\ \sf\longmapsto x=\dfrac{260}{13}$

$\\ \sf\longmapsto x=20$

Find the slope and y-intercept for the two linear functions.

tankabanditka [31]

Answer: Slope of the line given in the table: m = - 0.25

Y-intercept of the line given in the table: b = -4

Slope of the line given by the equation: m = 1.5

Y-intercept of the line given by the equation: b = 1

Step-by-step explanation: Slope of an equation is an indication of the steepness and direction of a linear graph. It is denoted as m and it can be calculated as:

m = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

Another way of determining the slope is as the form:

y = mx+b

For the table:

As in the table there are only points:

m = $\frac{-3 + 2.5}{-4+6}$

m = - 0.25

For the function:

The function is:

y = 3/2x + 1

m = 3/2

m = 1.5

Y-intercept is where the linear function crosses the y-axis, or when x=0. It can also be represented by the letter b.

For the table:

y = mx + b

According to the table, when y = -2.5, x = -6

-2.5 = - 0.25. (-6) + b

b = -2.5 - 1.5

b = -4

For the function:

y = 1.5x + 1

b = 1

In conclusion:

For the table: m = - 0.25 b = - 4
For the equation: m = 1.5 b = 1

Kids bought a package with 2 9/ 16 lb of ground meat to make hamburgers he was he has 2/5 pound of ground meat left about how ma

poizon [28]

Answer:

The quantity of ground meat he use for hamburgers is 2 $\frac{13}{80}$ pounds

Step-by-step explanation:

Given as :

The total quantity of ground meat bought to make hamburgers = 2 $\frac{9}{16}$

Or, The total quantity of ground meat bought to make hamburgers = $\frac{41}{16}$ pound

The quantity of ground meat left after use = $\frac{2}{5}$ pound

Now, let The quantity of ground meat used for hamburgers = x pound

So, x = The total quantity of ground meat bought - The quantity of ground meat left

Or, x = $\frac{41}{16}$ pound - $\frac{2}{5}$ pound

Or, x = $\frac{205-32}{80}$ pound

I.e x = $\frac{173}{80}$

∴ x = 2 $\frac{13}{80}$ pounds

Hence The quantity of ground meat he use for hamburgers is 2 $\frac{13}{80}$ pounds . Answer
