Answer:

<h2>a. JK and XY with line over them.</h2>

Step-by-step explanation:

The line over means that JK and XY are segments, that is, sides of each triangles.

The problems just give a relation between both triangle, setting an specific order. So, according to the hypothesis of the problem, the corresponding parts are:

  • JK side to XY side.
  • KL side to YZ side.
  • JL side to XZ side.
  • Angle J to Angle X.
  • Angle K to Angle Y.
  • Angle L to Angle Z.

All of these are corresponding elements. This means that if triangles are congruent, then each corresponding element of these are congruent, if triangles are similar, which is probably the case, then each corresponding pair of sides are proportional, and each pair of corresponding angle are congruent, because when it's about similarity, angles are congruent but sides are just proportional.

Therefore the right answer here is A.

. Ralph’s Fill Dirt and Croissant Shop in Spencer makes both grand and petit croissants. Each grand requires 1 ounce of flour an
Gwar [14]

Answer:

1

Step-by-step explanation:

let G be the number of grand croisssants, and P the number of petit croissants :

we have that 1 ounce of flour and 2 ounces of butter result in one G.

additionally, we have that 1/4 ounce of flour and 1/3 ounce of butter result in one P.

Ralph has 4 ounces of flour and 6 ounces of butter, If he bakes more than 1 G then he will never use all of his ingredients!, let's see:

1 G:

he now has 3 ounces of flour, and 4 ounces of butter,

now we need to figure out how many P's we would obtain with such amounts:

let x be the number of P's

1/4*x = 3=>x=12\\ 1/3*x=4=>x=12

which is reasonable, Ralph can bake 12 P's,

now with more than 1 G:

2G:

Ralph has now 2 ounces of flour and 2 ounces of butter, now we have to figure out that x is the same using the remaining ingredients

1/4*x = 2=>x=8\\ 1/3*x=2=>x=6

This is impossible.

3G:

he runs out of butter.

There is the answer, he is able to bake 1 grand croissant and 12 petit croissants
