Answer:
Hotdog costs $5.35 each and hamburger costs $0.18 each
Step-by-step explanation:
The difference in price between the two is the cost of 5 hotdogs.
So, $56.25 - $29.50 = $26.50
I hotdog would cost $26.50/5 = $5.35
Substituting the cost of one hotdog,
10($5.35) + 15ham = $56.25
$53.50 + 15 ham = $56.25
15 ham = $56.25 - $53.50
15 ham = $2.75
So, 1 ham = $2.75/15
= $0.18
Answer:
y= -6x+2
Step-by-step explanation:
Sec(theta) = 1 / cos (theta) = hypotenuse / x -coordinate
hypotenuse = 1 (because it is the radius of the unit circle)
sec (theta) = 1 / (-3/5) = - 5/3
cot (theta) = 1 / tan(theta) = x-coordinate / y - coordinate
cot (theta) = -3/5 / y
y^2 + (-3/5)^2 = 1 => y^2 = 1 - 9/25 = 16/25 = y = +/- 4/5
Third quadrant => y = -4/5
=> cot (theta) = (-3/5) / (-4/5) = 3/4
Pythagorean theorem is a^2 + b^2 = c^2
2. You are trying to find x which is c^2
so plug in the other numbers to the other letters. 9^2 + 17^2 = c^2
9^2= 81. 17^2= 289
81 + 289 = 370
370= c^2
Now all you have to do is square root the number
*square root sign* 370
19.24
c = 19.24
So, x = 19.24
