Last summer,Karl went to the beach every 2 days. Antonia went to the beach every 3 days.How often did they see each other at the beach?

Answers

I think it would be every six days because if you count by threes and then by twos you get six both times and they would see each other on the sixth day.   Hope that helped you :D
They see each other every 6 days. You just need to find the LCM of 2 & 3 which is 6.

For what values of x and y are the triangles to the right congruent by HL?

Answers

Based on the Hypotenuse-LengthTheorem of Congruence (HL), the values of x and y that will make both right triangles congruent are:

  • x = 8
  • y = 4

Recall:

  • Two right triangles are congruent to each other by the Hypotenuse-Length Congruence Theorem (HL) if the hypotenuse length and one leg of a right triangle is congruent to the hypotenuse length and leg of the other right triangle.

Thus, for both right triangles to be congruent, it means that their hypotenuse and one of their corresponding legs must be equal to each other.

Use this to create two equations and solve to get the value of x and y.

  • Equal Hypotenuse:

x + 4 = 3y\n\nx + 4 - 4 = 3y - 4\n\nx = 3y - 4(eqn. 1)

  • Equal legs:

x = y + 4\n\n (eqn. 2).

  • Find the value of y, by substituting x = (y + 4) into eqn. 1.

x = 3y - 4 (eqn. 1)

  • Substitute

y + 4 = 3y - 4\n\ny - 3y = -4 - 4\n\n-2y = -8\n\ny = 4

  • Find the value of x, by substituting y = 4 into eqn. 2.

x = y + 4\n\nx = 4 + 4\n\nx = 8

Therefore, based on the Hypotenuse-LengthTheorem of Congruence (HL), the values of x and y that will make both right triangles congruent are:

  • x = 8
  • y = 4

Answer:

x = 8 and y = 4

Step-by-step explanation:

For congruency the hypotenuse and a leg must be congruent, that is

3y = x + 4 → (1) ( Equating the hypotenuse )

x = y + 4 → (2) ( equating corresponding legs )

Substitute x = y + 4 into (1)

3y = y + 4 + 4

3y = y + 8 ( subtract y from both sides )

2y = 8 ( divide both sides by 2 )

y = 4

Substitute y = 4 into (2)

x = 4 + 4 = 8

Evaluate.

In a population of 1,000 students, 50 were asked by random sampling what their plans were after graduation from high school. Their responses are shown in the table. A 2-column table with 4 rows. Column 1 is labeled Intention with entries College, job, military, no plans. Column 2 is labeled Number of students with entries 27, 13, 2, 8. Using proportional reasoning, make a prediction about how many students you would expect to have plans to attend college. 27 50 = x 1000 27,000 = 50x About would have plans to attend college.

Answers

ok so
ratio
35/200=x/3000
7/40=x/3000
multiply both sides by 12000
2100=4x
divide both sides by 4
525=x
