Answer: 94.5

Step-by-step explanation:

If average of 9 students is 94, their total will be 94x 9 = 846

If the 10th student scores 99, the new total is 846 + 99 = 945

So, the new average will be

945/10 = 94.5

There are 1200 students at a school and 390 of them are boys if each classroom holds 30 students how many classrooms are needed

vodomira [7]

Answer:

40 classrooms

Step-by-step explanation:

Divide 1200 by 30.

1200÷30=40

If 390 students are boys just subtract 390 from 1200.

1200-390= 810

There must be 810 girls if there are 390 boys

What linear function represents the line given by the point slope equation y+7= 2/3(x+6)?

aleksandrvk [35]

Answer:

The graph of the line in the attached figure

Step-by-step explanation:

we have

$y+7=\frac{2}{3}(x+6)$

This is the equation of a line into point slope form

The slope is $m=\frac{2}{3}$

The line pass through the point (-6,-7)

To graph the line find the y-intercept

Remember that

The y-intercept of the line is the value of y when the value of x is equal to zero

For x=0

$y+7=\frac{2}{3}(0+6)$

$y+7=\frac{2}{3}(6)$

$y+7=4$

$y=4-7=-3$

The y-intercept is the point (0,-3)

with the point (-6,-7) and (0,-3) plot the line

see the attached figure
