thank you for helping and showing work so i know how to solve it in the future tysm

option A = 40(24)   =  option B = x (.1)       where x is her gross sales

40(24) = x(.1)

40(24)/.1 = x = sales = $9600

Picture of all of this:

2x-4y+9=0    is the same as    y= 1/2 x +9/4      slope is 1/2   perindicular slope is  - (1/ (1/2) ) = -2

so our line to construct will look like   y = -2x + b

now  6x-10y +24= 0   has x-intercept when y=0      at that point x= -4     so our line under construction must pass through this point   -4,0  

Substitute this point into our line under construction:       

0=-2(-4) + b    results in b=-8    

so our line is    y =  -2x -8              or      -2x -8 -y = 0         Perpindicular to the first line and passing thru (-4,0)

Sin = Opposite /Hypotenuse   Cosine = Adjacent / Hypotenuse Tangent = Opposite / Adjacent

Since you have all of the sides you can pick any of them and calculate the sin , cos or tan  then use the inverse function

(example sin^1)   to find the angle....

This is ONLY for RIGHT triangles

This is a calculator site, so you could actually save time and use the calculator yourself! But the answer is 231,28571429

1.2x = 6 you divide both sides by 1.2 and then you'll see that x = 5

A brief check; 1.2 x 5 = 6

10/37 + 71/82 = 820/3034 + 2627/3034 = 820+2627/3034 = 3447/3034 = 1.136124

THATS FROM THE RED BOOK COMMON CORE- A BALANCED APPROACH

A supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combined. How many pounds of each item does the supplier sell?

2.25 + 1 1/3=3.5833333 combined number of pounds of mulch and gravel sold.

2.25/3.583333 X 172=108 pounds of mulch that the supplier sells

(1 1/3) / 3.583333 X 172=64 pounds of gravel that the supplier sells.

 BTW lol

I'm guessing darkness too, but fog sounds acceptable too

x=6-1.2 

x=4.8

I believe that is an equation for slope.
