In a classroom of 33 students, the ratio of boys to girls is 3:8. How many boys are in the class?

1 answer:

6 0

9 because it's 3 boys to every 8 girls with 33 in the class together. so start with 6 boys which is 3+3 meaning there will be 16 girls being 8+8. together that makes 22 students then add another 3 boys bumps the total number up to 25 and for those 3 you need 8 girls which bumps 25 up to 33 meaning that in a class of 33 there will be 9 boys altogether

Before we begin, let's identify what kind of angles these are and are they related in any way?

These angles are both acute and they are both corresponding angles.
Corresponding angles are equal to each other, and we can use this fact to our advantage.

Since they are equal to each other, we can set the equations of 1 and 2 equal to each other. Like so,

1 = 2
83 - 2x = 92 - 3x

Now, we can solve for X by isolating it on one side.

83 - 2x = 92 - 3x

Add 3x to each side: (This basically moves the X on the right side to the left.)
83 - 2x + 3x = 92 - 3x + 3x
83 + x = 92

Subtract 83 on each side to isolate the X.
83 + x - 83 = 92 - 83
x = 92 - 83
x = 9

Therefore, X equals 9. To check our work, we can substitute X for 9.
83 - 2(9) = 92 - 3(9)
83 - 18 = 92 - 27
65 = 65 -
TRUE

So to conclude, Angle 1 is 65 degrees, Angle 2 is 65 degrees, and X equals 9.

Select all the statements that can be determined from the table given

Maurinko [17]

Answer:

Statements A and D

Step-by-step explanation:

A. Since all of the values surrounding x = 0.5 reflect across that point, there is a line of symmetry at x = 0.5

B. This is not a y intercept since in the point (-12,0) the x value is not zero and at y intercepts, it should be zero.

C. Same thing from statement B, the y value for the x intercepys should be zero, not 4 or -3.

D. To help visualize this, take the slope of the secant line from x = -4 to x = 0.

(8 - (-10))/(-4 - 0) = 18/(-4) or -9/2. Since the slop is negative, the function is decreasing on this interval.
