What is the value of a?

Kisachek [45]3 years ago

The answer is 41.41
Since we know the side that is opposite to a, and the hypotenuse, we have enough information to get the cosine of a. The cosine is 45/60. If we know the cosine of an angle, we can get the arccos of that value to get the angle. The arccos of 45/60 is about 41.41.

<u>Complete Question</u>

The table shows the number of grade 7 and grade 8 students on the student council at Jeremy’s school.

Number of Students

  • Grade 7 - 17
  • Grade 8 - 34

Answer:

C- The number of outcomes representing each grade level does not change after the first student is chosen.

Step-by-step explanation:

The ratio of Grade 7 students to Grade 8 students is:

17:34

This written in reduced form is 1:2

Therefore, initially, the six parts of the cube can be divided into the ratio 2:4 which Jeremy did.

However, after the first selection of a student, the ratio of Grade 7:Grade 8 student changes since the same student cannot be chosen more than once.

Therefore the cube rolls represent only the first student choice and may not be accurate for subsequent rolls.

The correct option is C.

What is the solution to 5x - 3 = 12SHOW YOUR WORK
Dafna1 [17]

Answer:

Answer =  X= 3

Step-by-step explanation:

Let's solve your equation step-by-step.

5x − 3 = 12

Step 1: Add 3 to both sides.

5x − 3 + 3 = 12 + 3

5x = 15

Step 2: Divide both sides by 5.

5x/5 = 15/5

Answer = X= 3

Midpoint of the x intercepts of f(x)=(x-4)(x+4)
lorasvet [3.4K]
The x-intercept is defined to be the value of x when y is zero. Based on the graph of the function: f(x) = (x-4)(x+4), the x-intercepts are located at (-4, 0) and (4,0). At these points the graph intersects the x-axis. The midpoint of the x-intercepts is located at the middle of the two points. In this case, the graph shows that it is at the origin or at (0,0).
