The product of 8 and the sum of a number and 12 is 240

mezya [45]

Answer:

Step-by-step explanation:

Let the number be 'x'

Sum of 'x' and 12 = x +12

The product of 8 and the sum of a number and 12 = 8* (x +12)

= 8*x + 8*12

= 8x + 96

8x + 96 = 240

Subtract 96 from both sides

8x + 9 6 - 96 = 240 - 96

8x = 144

Divide both sides by 8

x = 144/8

x = 18

Which is an equation in point slope form of the line that passes through the points (7 -8) and has a slope of -3

Nataly [62]

Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13

Me. Ellis is a teacher who tutors after school. Of the students he tutors, 30% need help in computer science and 70% need assist

Anna11 [10]

Answer: There are 82.5% after school students who are enrolled in his classes.

Step-by-step explanation:

Let the total number of students be 100

Percentage of students who need help in computer science = 30%

So, number of students who need help in computer science = 30

Percentage of students who need help in maths = 70%

So, number of students who need assistance in maths = 70

Of the students who need help,

40% are enrolled in Mr. Ellis's class during the school day,

So, it means 60% are enrolled in his class after the school day.

Number of students who are enrolled in his class after the school day = 60

Number of students who need help in Maths is given by

$\frac{70}{100}\times 60=42$

Of the students that need help in maths, percent of students are enrolled in his class during the day = 25%

So, number of students who need help in maths and enrolled in his class after school hours

$\frac{75}{100}\times 42=31.5$

Number of students who need help in computer science and enrolled in his class after school hours

$\frac{30}{100}\times 60=18$

Therefore, there are $31.5+18=49.5$ students who joined his class after school hours,

Percentage of the after students who are enrolled in Mr. Ellis's classes is given by

$\frac{49.5}{60}\times 100=82.5\%$

Hence, there are 82.5% after school students who are enrolled in his classes.

A local business prides itself on paying its employees well over the federal minimum wage. The amount over minimum wage and the

algol [13]

To approximate a scatterplot, we use lines of best fit. Sometimes these aren't lines because the trend may not be linear, like temperature. The average temperature a town tracked monthly would look like a sinusoid. Here though, we can see that this is probably linear. It increases every other year at a near constant rate. Even plugging in numbers gives us near enough values that the others could not compare with. The first function has a problem - it grows too fast. The second equation also has a problem, the slope. The wage is increasing so the function should too. The third is most likely the right one. The fourth does not work because it becomes negative almost immediately.

Through some inductive reasoning, we can say that the most probably line of best fit would be C.
