Answer:

  • 42 students; (28 students); 70 students
  • (60%); 40%; (100%)

Step-by-step explanation:

The percentages total 100%, so the missing percentage is

  100% - 60% = 40%

The numbers on the number lines are proportional, so now you can write ...

  ?/100% = 28/40% . . . . . . ? total students

Multiplying by 100% gives ...

 ? = 28/0.4 = 70 . . . . . total students

Then the 60% portion of students can be found two ways:

  60% × 70 = 42 students . . . . 60% of students

  70 -28 = 42 students

Find the equation of the line that passes through the points (12,21) and (46,33). V.35r-162
AnnZ [28]

Answer:

the answer is Y=(6/17)X + (285/17)

Step-by-step explanation:

1. Identify the X and Y coordinate of each point.            

for example, the first point could be (12,21), therefore X1 = 12 and Y1 = 21 and the second point is then (46,33), therefore X2 = 46 and Y2 = 33

2. to find the equation of the line it is necessary to find the slope.

knowing that the equiation of the slope is M = Y2-Y1/X2-X1 we replace

  m=\frac{33-21}{46-12}=\frac{12}{34} and then we simplify the result to \frac{12}{34}

3. Using the Point-slope equation which is  Y-Y1=M(X-X1) we replace

 Y-33=\frac{6}{17}(X-46)

Y=\frac{6}{17}X-\frac{276}{17}+33

Y=\frac{6}{17}X+\frac{285}{17}

Prove sums of angles in a triangle is 180 degree
goldfiish [28.3K]

Answer:

because a triangle has 3 sides and has 3 angles

so each angle on a equilateral triangle has 60 degrees which means

  60 x 3 = 180

Step-by-step explanation:

because a triangle has 3 sides and has 3 angles

so each angle on a equilateral triangle has 60 degrees which means

  60 x 3 = 180
