Answer:

2, 12, 36, 80

Step-by-step explanation:

Substitute n = 1, 2, 3, 4 into the n th term formula, that is

a₁ = 1³ + 1² = 1 + 1 = 2

a₂ = 2³ + 2² = 8 + 4 = 12

a₃ = 3³ + 3² = 27 + 9 = 36

a₄ = 4³ + 4² = 64 + 16 = 80

how do you indicate congruent segments in a diagram? how do you indicate congruent angles in a diagram?
ICE Princess25 [194]

9514 1404 393

Answer:

  • segments: using the same number of hash marks
  • angles: using the same number of arcs, or hash marks on an arc

Step-by-step explanation:

The attached diagram shows that segments AC and BD are congruent by using a single hash mark on each of those segments. If other segments are congruent, but not congruent to these two, the "decoration" would be different, probably two hash marks. Segments marked with the same "decoration" are intended to be understood as congruent.

__

The "decoration" used for congruent angles is an arc of some kind. Here, a single arc is used to signify angle CAB is congruent to angle DBA. Additional arcs could be used for other congruent angles, or hash marks can be put on the arcs.

the average mark of three pupils are 68. what is the ratio of 5:4:3. how many marks did the best student get? HELP ME! ​
noname [10]

Answer:

85, 68, 51

Step-by-step explanation:

Average: The sum of all the numbers divided by the number of numbers

If the ratio of the scores is 5 : 4 : 3, let's just set it as 5x : 4x : 3x

Then using the definition of an average, we can write this equation.

(5x + 4x + 3x) / 3 = 68

Multiply both sides by 3.

5x + 4x + 3x = 68 * 3

Simplify.

12x = 204

x = 17

Now, substitute x = 17 into the original scores (5x, 4x, and 3x)

5x = 5 * 17 = 85

4x = 4 * 17 = 68

3x = 3 * 17 = 51

Just in case, let's check this answer. Find the average of the 3 test scores.

(85 + 68 + 51) / 3 =

204 / 3 = 68

Thus, the answers are correct
