3. The lacrosse team is raising money by selling cheesecakes. The players plan to sell an entire cheesecake for $24.00 each and
vodka [1.7K]

To reach a raise of $ 700, you can sell 20 entire cheesecakes and 63 slices, or 10 entire cheesecakes and 132 slices, or 15 entire cheesecakes and 98 slices.

To determine, if they want to raise at least $ 700, how many of each could they sell, listing three possible combinations of entire cheesecakes and slices of cheesecake the players could sell to reach their goal, the following calculation must be performed:

  • C + S = 700
  • 24 x 20 = 480
  • 700 - 480 = 220 / 3.5 = 62.85
  • 24 x 10 = 240
  • 700 - 240 = 460 / 3.5 = 131.42
  • 24 x 15 = 360
  • 700 - 360 = 340 / 3.5 = 97.14

Therefore, to reach a raise of $ 700, you can sell 20 entire cheesecakes and 63 slices, or 10 entire cheesecakes and 132 slices, or 15 entire cheesecakes and 98 slices.

Indicate the method you would use to prove the two A's 2. If no method applies, enter "none".
Strike441 [17]

Answer:

1) ASA

2) none

3) ASA

Step-by-step explanation:

In the first picture we have two angles and one included side of one triangle is congruent to corresponding two angles and one included side of another triangle, therefore by ASA postulate of congruence both triangles are congruent.

In the second picture , the two have two equal angles, the third angle of both triangles by using angle sum property =,

Now, two corresponding angles and one included side (10 units) of both triangles are congruent  therefore by ASA postulate of congruence both triangles are congruent.

In the third picture, we have two triangle with one same vertex, then their vertical angles must be congruent.

Thus, in third picture, two angles and one included side of one triangle is congruent to corresponding two angles and one included side of another triangle, therefore by ASA postulate of congruence both triangles are congruent.

How many solutions does the system of equations have 3x=-12+15 and x + 4y =5
Sphinxa [80]

Answer:

infinitely many solutions

Step-by-step explanation:

I assume that you meant

3x = -12y + 15 and x + 4y =5 (you accidentally omitted the 'y')

Multiplying the second equation by 3 yields

3x + 12y = 15

... which is identical to the first equation.  Thus, the two lines coincide, and we conclude that there are infinitely many solutions.
