A school keeps track of the percentage of scholars who pack lunch versus buy lunch. On Monday, 80% of scholars packed lunch. On Tuesday, 70% of the scholars who packed lunch do so again, and 50% of those who bought lunch on Monday ​pack ​lunch on Tuesday. Assume all scholars either pack lunch or buy lunch. Find the percent change in the number of scholars who bought lunch from Monday to Tuesday, and indicate whether this was an increase or decrease.

Answer: y = -2x² + 920x - 84168

suppose: the equation of the parabola is y = ax² + bx + c

because the parabola passes through (126,0); (134,3200); (334,0)

=> we have the equations:

126².a + 126b + c = 0

134².a + 134b + c = 3200

334². a + 334b + c = 0

⇒ a = -2

    b = 920

    c = -84168

=>  the equation of the parabola is y = -2x² + 920x - 84168

There are certain reasons that the regulations influence wages, among them the main influence is that they create laws dealing with jobs and income.

A wage is a sum of money paid by an employer to an employee for work completed over a set period of time.

Compensatory payments, such as minimum wage, annual bonuses, and prevailing wage and remunerative payments, such as prizes and tip payouts, are examples of wage payments.

These wages are influenced by the regulations in which the laws dealing with jobs and income.

Therefore, option B is correct.

Answer:

Therefore, the rise will be 0.95 m

Step-by-step explanation:

As the waterslide has an angle of elevation of 20 degrees.

Ф = 20°

And we have to determine the rise for a run of 2.6 m.

All we need is to use the trigonometric ratio of tan Ф

Because

As

run = 2.6 m

Ф = 20°

so

tan Ф = rise/run

tan (20) = rise/run

rise = tan (20) × 2.6

rise = 0.95 m

Therefore, the rise will be 0.95 m

Answer:

420

Step-by-step explanation:

If there were 1200 people, and 65 percent were women, that means the rest of the crowd are men, which is 35 percent. By multiplying 35 percent by the overall population, 1200, (1200*35/100), you'll get 420 men.

Answer:

Step-by-step explanation:

The answer is 420

Answer:

y = x - 2

Answer:

y= -1/2 + 2

Step-by-step explanation:

To find m or the slope you need to find 2 locations that the line intercepts a point on the graph. I used (0,2) and (2,1).

Then you find the difference of the x and y coordinates. (x,y)

X-coordinates: 0 and 2.    0 - 2 = -2

Y-coordinates: 2 and 1.      2 - 1 = 1

A slope fraction is the difference of y over the difference of x coordinates. It would be written as 1/-2 or -1/2. m= -1/2

To find the b value, just look at the y-intercept or where the line intercepts the y-axis. Which is at (0,2). So b=2

Give brainliest

Answer:

B

Step-by-step explanation:

The question is looking for an equation in slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. The y-intercept is +4, which all of the answers show, so you must find the slope.

The slope is the change in y over change in x, more commonly referred to as rise over run. So count how many units the graph changes vertically and horizontally, in this case, 1 up and 2 right, so the slope is equal to 1/2. If you have a graph where the line shifts up and left, or down and right, then the slope is negative. Additionally, one way to visually check your work is to remember slopes equal to less than -1 or greater than +1 will be steeper while fraction slopes will make the slope flatter; basically the closer to zero the less steep.

Answer:

y=9x +5  , 8 hours

Step-by-step explanation:

9 dollars per hour = 9x

travel allowance = 5

y = 9x + 5

77 = 9x + 5

77 = 9x +5

-5          -5

72= 9x

72/9 = x

Answer:

24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1

Step-by-step explanation:

Given the following temperature values :

2, 6.9, 17 1/2 , −5.1, 24, − 1/4 , and 1.45.

Ordering the values above from greatest to least ; (descending order)

Expressing all temperature values in the same format :

Let's make sure all values are in decimal to make comparison easier :

2.0

6.9

17 1/2 = 35/2 = 17.5

-5.1

24.0

-1/4 = - 0.25

1.45

We begin from the temperature value which is highest :

24 > 17.5 > 6.9 > 2.0 > 1.45 > - 0.25 > - 5.1

Hence ;

24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1
