The answer is A. If there are 30 people and 14 are boys, that means there are 16 girls. So you put 16/14 and simplify so that would be 8/7.

A movie theater has been charging $10.00 per person and selling about 500 tickets on a typical weeknight. After surveying their

kifflom [539]

Answer:

$p(x) = -0.01x + 15$

Step-by-step explanation:

Given

Let x represent the number of tickets, and p the charges

$(x_1,p_1) = (500,10)$

A reduction of 50c gives an increment of 50 tickets.

This gives:

$(x_2,p_2) = (500+50,10-0,5)$ ---- $50c = \$0.5$

$(x_2,p_2) = (550,9.5)$

Required

Determine the demand function

First, calculate the slope:

$m = \frac{p_2 - p_1}{x_2 - x_1}$

$m = \frac{9.5 - 10}{550-500}$

$m = \frac{-0.5}{50}$

$m = -0.01$

So, the equation is:

$p = m(x - x_1) + y_1$

$p = -0.01(x - 500) +10$

$p = -0.01x + 5 +10$

$p = -0.01x + 15$

Hence, the function is:

$p(x) = -0.01x + 15$

I’ve been stuck on this for days I just need a simple answer

likoan [24]

Answer:

408

Step-by-step explanation:

Surface area formula is A=2(wl+hl+hw)

Substituting these values into the formula you would get

2·(3·8+4·8+4·3)=136

136 accounts for one rectangular prism.

Since you have 3 multiply 136 by 3 which would leave you with 408

What is the sum of the two largest numbers in the list

Dmitriy789 [7]

Answer:

$\frac{25}{39}$

Step-by-step explanation:

The given numbers are

$\frac 13,~\frac 27,~\frac 3{10},~\frac 4{13},~\frac 5{17}$

We need to find the sum of the two largest numbers in the list.

The values of each number are

$\frac{1}{3}=0.33..$

$\frac{2}{7}\approx 0.286$

$\frac{3}{10}=0.3$

$\frac{4}{13}\approx 0.308$

$\frac{5}{17}\approx 0.294$

Using these we can say that

$\frac{2}{7}$

It means two largest numbers in the list are $\frac{4}{13}\text{ and } \frac{1}{3}$ .

The sum of these two number is

$Sum=\frac{4}{13}+\frac{1}{3}$

$Sum=\frac{4\cdot 3+1\cdot 13}{39}$

$Sum=\frac{25}{39}$

Therefore, the sum of the two largest numbers in the list is $\frac{25}{39}$ .

What is the product of (-4x2-5x-1)(4x2-6x-2)

Stells [14]

(-4x2-5x-1)(4x2-6x-2)

Final result :

-2 • (13x + 1) • (2x2 - 3x - 1)
Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2".

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(-13x - 1) • ((22x2 - 6x) - 2)
Step 2 :

Pulling out like terms :

3.1 Pull out like factors :

-13x - 1 = -1 • (13x + 1)

Step 3 :

Pulling out like terms :

4.1 Pull out like factors :

(4x2 - 6x - 2) = 2 • (2x2 - 3x - 1)

Trying to factor by splitting the middle term

4.2 Factoring 2x2 - 3x - 1

The first term is, 2x2 its coefficient is 2 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is -1

Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2

Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is -3 .

-2 + 1 = -1
-1 + 2 = 1

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Step 4 :

Pulling out like terms :

5.1 Pull out like factors :

-26x - 2 = -2 • (13x + 1)

Final result :

-2 • (13x + 1) • (2x2 - 3x - 1)
