The school district is interested in knowing if the students and parents are supportive of a longer school day. The school condu
Soloha48 [4]

76% of students were not supportive.

you find the answer by gathering the total number of students not supportive over the total number of students. in this case it would be \frac{190}{250} . then, you simplify it so that its a number over 100, so it would be \frac{76}{100} . Then, you just convert that to a percentage, 76%

The equation for line j can be written as y=2x + 8. Another like k is perpendicular to line j and passes through the point (6,-6
Semmy [17]

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 8 ← is in slope- intercept form

with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2}, thus

y = - \frac{1}{2} x + c ← is the partial equation

To find c substitute (6, - 6) into the partial equation

- 6 = - 3 + c ⇒ c = - 6 + 3 = - 3

y = - \frac{1}{2} x - 3 ← equation of line k

The DingGnat Doorknob Company intends to sell a new line of square doorknobs. The price-demand function is p ( x ) = 48.5 − 0.09
pickupchik [31]

Answer:

a. 135 doorknobs

b. R(x) = 48.5x-0.09 x^2

Step-by-step explanation:

The price-demand function is:

p(x) = 48.5-0.09 x

a. At a price of $36.30, the number of doorknobs sold, 'x' is:

p(x) = 48.5-0.09 x\\36.30 = 48.5-0.09 x\\x= \frac{48.5-36.30}{0.09}\\x=135.55

Rounding it down to the nearest whole unit, the company can sell 135 doorknobs at $36.30

b. Revenue is the product of the price, p(x), by the demand, x. Therefore, the Revenue function is:

R(x) = x*p(x)=x(48.5-0.09 x)\\R(x) = 48.5x-0.09 x^2
