Triangle ABC is similar to XYZ

Therefore, c times a scale factor is equal to z

Since c is 12 and z is 18, and we are trying to find the value of a, which is in the smaller figure, the scale factor from big to small is 12/18 or 6/9, Since I want to minimize x's value to get a, the scale factor must go from big to small, which is why the scale factor has to be 12/18 or 6/9. From there, to find a's value, i multiply 27 by 6/9 which is equal to 18. Therefore a=18

Franco made a dozen muffins for his party. Upon taking them out of the oven,
Naddik [55]

Answer:

Option B.

Step-by-step explanation:

This question is incomplete; find the complete question with the attachment.

Franco made number of muffins = a dozen

A dozen muffins = 12 muffins

Number of muffins were burned = 2

Remaining muffins = 12 - 2 = 10

Franco served 7 of the remaining non-burned muffins,

Fraction of muffins served = \frac{7}{10}

Remaining muffins = 3

Fraction of remaining muffins = \frac{3}{10}

Fraction of remaining non-burned muffins we can get from,

\frac{10}{10}-\frac{7}{10}=\frac{3}{10}

Option B is the correct equation.

Find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6).
Sergio [31]
Hello,

Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3

y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)
