The ratio of boys to girls taking geometry this year is 27:31. If 246 students are ebrolled in geometry this year, approximately how many of them are boys and how many of them are girls?

Answers

Answer 1

Answer:

115 boys

131 girls

Step-by-step explanation:

Given data

The given ratio= 27:31

The sum of the ratio = 27+31= 58

The total number of students taking geometry= 246

Let us apply the part to all method

let the number of boys be x

27/58= x/246

cross multiply

58*x= 246*27

58x=6642

x= 6642/58

x=114.5

Hence the number of boys is 115

Thefore, the number of girsl= 246-115= 131

Carlos cut StartFraction 5 Over 12 EndFraction of a yard of cloth into 5 pieces of equal length. What was the length of each piece of cloth? HELP?????????!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

1/12 yard

Step-by-step explanation:

From the above question:

5 pieces of equal length = 5/12 yards

1 piece of equal length = x yard

Cross Multiply

5 pieces × x = 1 piece × 5/12 yards

x = 1 piece × 5/12 yards/5 pieces

x = 5/12 ÷ 5

x = 5/12 × 1/5

x = 1/12 yard

The length of each piece of cloth is 1/12 yard

solve for x. please help asap we have a test on these tomorrow and i have no idea what’s going on.

Answers

Answer:

x = 20°

Step-by-step explanation:

You know the horizontal line is 180°. If the left side of the horizontal line is 90° (right angle), then the right side of the horizontal line should be 90° too. (180° - 90° = 90°)

Thus, 90° = 43° + 2x + 7°

2x = 90° - 43° - 7°

    = 40°

x = 40° ÷ 2

x = 20°

Answer:

X = 2

Step-by-step explanation:

As the lines are perpendicular...

90 = 43 + 2x + 7

Solve for x by making x the subject.

90 - 43 - 7 = 2x

40 = 2x

40/2 = x

20 = x

therefore, x = 2
