Of the 400 6th grade students at Aviara Oaks Middle School, the ratio of boys to girls is 2:3. Of the 360 students at Valley Middle School, the ratio of boys to girls is 3:5.

Which middle school has more boys attending their school?



How many girls attend AOMS?




How many girls attend VMS?




What is the ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School?

Answers

Answer:

Step-by-step explanation:

Aviara Oaks Middle School:

Total student = 400

Boys : girls = 2:3

Boys = 2x , girls = 3x

2x + 3x = 400

       5x = 400

         x = 400/5

         x = 80

Number of boys = 2x = 2*80 = 160

Number of girls = 3x = 3 *80 = 240

VMS:

Total student = 360

Boys :  girls = 3 : 5

Number of boys = 3x

Number of girls = 5x

3x + 5x = 360

       8x = 360

        x = 360/8

       x =  45

Number of boys= 3x = 3 *45 = 135

Number of girls = 5x = 5 * 45 = 225

AOMS school has more boys attending their school.

Ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School = 240 : 225

                                    = 48 : 45

use the bar diagram to help you solve the equation 4x-12=16.

Answers

Answer:

x = 7

Step-by-step explanation:

4x−12=16

Step 1: Add 12 to both sides.

4x−12+12=16+12

4x=28

Step 2: Divide both sides by 4.

4x/4 = 28/4 = 7

x=7

SPORTS A coach uses a metric to determine the athletes that make the Varsity, Junior Varsity A, and Junior Varsity B teams. The total number of points possible on a skills test is 350. Athletes will make "Varsity" with at least 90% of the points. Athletes will make "Junior Varsity A" for 70-89% of the points. Athletes will make "Junior Varsity B" for 50-69% of the points. The table shows the number of points for each athlete that tried out.

Answers

Answer:

there is no picture. :)

Step-by-step explanation:

Answer:

Varsity = 12

Jr Varsity A = 10

Jr Varsity B = 11

Step-by-step explanation:

Varsity = at least 90%  = 350 times 90% = 315

Anything 315-350

Jr Varsity A = 70-89%

350 times 70% = 245

350 times 89% = 311.5

Jr Varsity b = 50-69%

350 times 50% = 175

350 times 69% = 241.5

Evaluate Sin^-1 sqrt2/2

Answers

Step-by-step explanation:

Let x = arcsin(√2/2).

We have sinx = √2/2, which is a basic trignometry identity. (sin45° = √2/2)

Since the range of arcsinx is [-90°, 90°] and 45° is within the range, the answer is 45° or π/4.

Use the slope formula to determine the slope of the line containing the two points.
