Profit is always calculated as revenue minus expenses. If a company’s expenses were $10 million, write an equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars). Then, determine the profit when revenue is $25 million.
a.
P = 10 minus R; $15 million
b.
P = R minus 10; $15 million
c.
P = R minus 10; $35 million
d.
P = 10 minus R; $35 million
Answer:
b.
P = R minus 10; $15 million

Please help me. I can't figure it out? Find the slope of a line passing through the following two points. (1 Point) (3, 4) and (-5, 2) O 2 O O
Answer:
1/4
Step-by-step explanation:
The formula is y2-y1 over x2-x1.
(Remember that or another problem like that)
(3, 4) (-5,2)
x1 y1 x2 y2
We would do: 2-4 over -5-3
2-4=-2
-5-3=-8
Your answer would be: -2/-8, which is simplified to 1/4 because when you divide two negative numbers, you get a positive.
A chemist has a solution of 65% pure acid and another solution of 30% pure acid. How many gallons of each will make 350 gallons of 55% pure acid solution?
Answer:
250 of 65% acid
100 gallons of 30% acid
Really sorry if this is incorrect, I had this question on my Lesson 16 test, and I don't know if it's correct or not...
Following are the calculation to the given question:
Assuming
x=The number of gallons of pure acid [tex](50\%)[/tex]
y = The number of liters of pure acid at [tex](80\%)[/tex] a concentration
[tex]\to x+y = 350[/tex]
The total quantity of gallons of each of the two types of pure acids............(1)
[tex]\to 0.65x+0.30y = 0.55(x+y)[/tex]
the mixture's acidity
[tex]\to 0.65x+0.30y = 0.55(350)\\\\\to 0.65x+0.30y = 192.5 ..........(2)[/tex]
So we have two equations and two variables to work with.
[tex]\to x+y = 350\\\\\to 0.65x+0.30y = 192[/tex]
multiply the first equation by [tex]0.30[/tex]
[tex]\to 0.30x+0.30y = 105\\\\\to 0.65x+0.30y = 192[/tex]
Subtract the second equation from the first
[tex]\to 0.35x = 87\\\\\to x = 248. 57 \approx 248 \ gallons\\\\ \to y = 350-248 = 102\ gallons\\\\[/tex]
As a result, we'll need 248 gallons of 65% pure acid and 102 gallons of 30% pure acid.

1. In a parallelogram ABCD, AD=12cm. if the altitudes corresponding
to sides AB and AD are respectively 8cm and 7cm find AB.
Answer:
10.5 cm
Step-by-step explanation:

12 x 7 = AB x 8
AB = 12x7 / 8 = 21/2 = 10.5
The area of a rectangle is represented by the polynomial x^2+3x-6x-18. What are the length, width, and area of the rectangle if x=12?
Answer:
Length = 15
Width = 6
Area = 90
Step-by-step explanation:
Area of the rectangle = [tex] {x}^{2} + 3x - 6x - 18[/tex]
Lets factorise the polynomial
[tex] = > x(x + 3) - 6(x + 3)[/tex]
[tex] = > (x + 3)(x - 6)[/tex]
We know that Area = Length × Width
Let the length be (x + 3) & width be (x - 6)
Its given in the question that x = 12. So putting the value of x gives ,
Length = [tex]x + 3 = 12 + 3 = 15[/tex]
Width = [tex]x - 6 = 12 - 6 = 6[/tex]
Area = Length × Width = 15 × 6 = 90

help i’m stuck i’ll give brainliest
Write equation of a line in point slope form that passes through (3,8) and has a slope of
5?
Answer:
y = 5x - 7
Step-by-step explanation:
(3 , 8) ; slope(m) = 5
Equation of the line: y - y₁ = m( x- x₁)
y - 8 = 5(x - 3)
y -8 = 5x - 5*3
y-8 = 5x - 15
y = 5x - 15 +8
y = 5x - 7
helpppp fasttt What is the area of the shaded region
Answer:
50.2 cm^2
Step-by-step explanation:
Formula for the area of a circle: [tex]\pi r^{2}[/tex]
Radius of bigger circle = 5
Area of big circle = 25 * 3.14 = 78.5
Radius of smaller circle = 3
Area of small circle = 9 * 3.14 = 28.26
Now, we subtract:
78.5 - 28.26 = 50.24 <--- Because we have to round to the nearest tenth, the final answer is 50.2
Answer:
50.2 cm²
Step-by-step explanation:
Find the area of both circles and subtract them.

have a wonderful day!!! :) :)
can someone please answer these and explain how you did it
2x - 7 = 11
7x + 1 = 22
3x - 8 = 22
8x +5 = 45
2x-7 = 11
7 goes to the other side
2x=11+7
2x = 18
x=18/2
x=9
7x + 1 = 22
1 goes to the other side
7x=22 - 1
7x=21
x=3
3x - 8 = 22
8 goes to the other side
3x = 22+8
3x=30
x=10
8x+5 = 45
5 goes to the other side
8x=40
x=40/8
x=5

Given:
The graph of an exponential function.
To find:
The function in the form of [tex]f(x)=ab^x[/tex].
Solution:
The general form of an exponential function is
[tex]f(x)=ab^x[/tex] ...(i)
From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.
For x=0 and f(x)=4,
[tex]4=ab^0[/tex]
[tex]4=a(1)[/tex]
[tex]4=a[/tex]
For x=1 and f(x)=7,
[tex]7=ab^1[/tex]
Putting a=4, we get
[tex]7=4(b)[/tex]
[tex]\dfrac{7}{4}=b[/tex]
Substitute a=4 and [tex]b=\dfrac{7}{4}[/tex] in (i).
[tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex]
Therefore, the required exponential function is [tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex].
