Answer:
P = 0.5c - 75
Step-by-step explanation:
Profit is = selling price. - cost price
Cost price is the amount the supplies were bought = $75

0.5 * c = $0.5c
The profit here is thus;
P = 0.5c - 75

what is an equation of the line that passes through the points 0,-1 and 6,1
put answer in fully reduced form
Answer: x - x1/ x2- x1 = y -y1 / y2-y1
x - 6/ -6-6= y - 1/ -1 -1
x -6/-12 = y -1 /-2
-2(x-6) = -12 (y-1)
-2x +12 = -12y +12
12y = 2x +12-12
y= 2x/12
y= x/6
Step-by-step explanation:
Answer:
y=1/3x-1
Step-by-step explanation:
y= 1 over 3x minus 1

How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-lifeIn this case,
a = 904 is the starting amountH = 60 is the number of days until another half-life occursWhen x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.
what is the period of the sinusoidal function
Answer:
10Step-by-step explanation:
Period is the distance between two consecutive maximum points, or two consecutive minimum points.On the given graph the period is the distance between maximum points -7 and 3:
3 - (-7) = 10Answer:
The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.
From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units
Therefore, 10 units is the right answer.

Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!
Find the common difference of the arithmetic
sequence 13,9,5,
Answer: -4
Step-by-step explanation:
13 - 9 = 4
9 - 5 = 4
so, we can see that it is decreasing by 4 each time.
Answer:
common difference is -4
Step-by-step explanation:
The common difference is the amount we add between terms
13 + d = 9
Subtract 13 from each side
13+d-13 = 9-13
d = -4
Check
9+d = 5
9 + -4 = 5
5= 5
This is true so the common difference is -4
The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.
Answer:
18x - 36
Step-by-step explanation:
In an equilateral triangle the 3 sides are congruent, then
perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms
= 18x - 36
The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
As we know in an equilateral triangle the 3 sides are congruent.
The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12
Combine the likewise terms and we get
The perimeter of the triangle = 18x - 36
Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.
