Lonna gave away 13/8 pie to her neighbor. Each pie was cut into 8 pieces. How many pieces of pie did lonna give to her neighbor

tankabanditka [31]

Answer:

13 pieces

Step-by-step explanation:

We are given that each pie was cut into 8 pieces .

therefore 1 pie is equal to 8 pieces

1 pie = 8 pieces

Lonna gave 13/8 pie to her neighbor .

So multiply both sides with 13/8 in the above equation in order to make the right side into 13/8 pie and to find the corresponding number of pieces .

1× $\frac{13}{8}$ pie=8× $\frac{13}{8}$ pieces

$\frac{13}{8}$ pie = 13 pieces

HELP WILL MARK BRAINLIEST!!!

Rainbow [258]

Answer:

Let's see what to do buddy..

Step-by-step explanation:

_________________________________

STEP (1)

We know that the quadratic functions form are like this :

$y = a \: {x}^{2} + b \: x + c$

The quadratic function opens upward so ;

$a > 0$

The axis of parabolic symmetry passes through the vertex of the parabolic.

So we know that x vertex is equal to -2.

The vertex's x is finding from this equation:

$x = - \frac{b}{2a} \\$

So we have :

$- 2 = - \frac{b}{2a} \\$

Multiply the sides of the equation by <em>2</em><em>a</em> :

$b = 4a$

_________________________________

STEP (2)

A quota passes through points (-3,2) and (0,11) , so points (-3,2) and (0,11) must be true in the quota equation.

$y = f(x) = a{x}^{2} + bx + c \\ \\b = 4a \\ \\ y = f(x) = a {x}^{2} + 4ax + c$

$f( - 3) = 2 \\ \\ a ({ - 3})^{2} + 4a( - 3) + c = 2 \\ \\ 9a - 12a + c = 2 \\ \\ - 3a + c = 2 \\ \\ \\ \\ f(0) = 11 \\ \\ a ({0})^{2} + 4a(0) + c = 11 \\ \\ c = 11$

$- 3a + c = 2 \\ \\ c = 11 \\ \\ - 3a + 11 = 2 \\ 11 \: goes \: to \: the \: other \: side \: \\ \\ - 3a = 2 - 11 \\ - 3a = - 9 \\ divided \: the \: sides \: of \: the \: equation \: by \: - 3 \\ a = 3$

And we're done.

Thanks for watching buddy good luck.
