AABC is similar to AAXY by a ratio of 3.2. If BC = 24, what is the length of XY?
dusya [7]

Answer:

XY = 16

Step-by-step explanation:

The ratio is 3 to 2 meaning that the sides of the triangle ABC and triangle AYY are in a ratio of 3 to 2.   You are comparing the big triangle to the small triangle and the sides are compared the same way.

3:2 = 24:XY                  

 3/2 = 24/XY

 3 XY = 48

 XY = 48/3

  XY = 16

6+8x-9=11x+14-3x, can this equation be always, sometimes, or never true.
goblinko [34]
To answer the question above, simplify both sides of the equation. This gives,
                         8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
                             -3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.

Juan scored 15 points more on this test than
maw [93]

Juan's least integer scores in both tests will be 85 and 100 respectively.

  • Test average of his two scores is atleast 92

Let :

  • Score on test 1 = b
  • Score on test 2 = b + 15

Average score can be related thus:

  • (Sum of score ÷ number of test) ≥ 92
  • (b + b + 15) ÷ 2 ≥ 92
  • (2b + 15) ÷ 2 = 92
  • 2b + 15 = 184
  • 2b = 184 - 15
  • 2b = 169
  • b = 169 ÷ 2
  • b = 84.5

Therefore, since both scores are integers, his least scores on both tests will be ::

  • 85 and (85 + 15) = 100
