The expression showing the number of students in the drama club the next year is 15+d.
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, there are 20 students in a drama club,
5 of them will leave in next year, and d students will join,
We are asked to construct an expression to represent the total number of students in the drama club next year.
So, the present number of students in the club = 20
After next year = 20-5 = 15
After the joining = 15+d
Hence the expression showing the number of students in the drama club the next year is 15+d.

EXPLAIN how you would graph the line y = 1/3x + 5
Answer:
Okay so this is the best way to explain it, its already in y=mx+b form which is the easiest way to graph something, its where m= slope and b=the y-intercept so 1/3 is m so the slope is 1/3 but first we need to mark the y coordinate which is 5, so on your graph dot (0,5) then from that go up 1 and right 3 then that should be your graph!!! I've included pictures to help you know what it should look like.

After a 2 1/2 hour rainstorm, there are 5 inches of water in a bucket outside. What is the rate per inch?
Answer:
2 inches per hour
Step-by-step explanation:
2 1/2 hours is equivalent to 150 minutes.
Set up a proportion; let x equal inches of rain
[tex]\frac{5}{150}[/tex]=[tex]\frac{x}{60}[/tex]
Cross multiply -> 150x=300
Divide both sides by 150 to get -> x=2

I need to find the AREA of these 6 circles using 3.14.
Answer I don't know the answer but i can help you find it out, so basically your going to times 3.14 by the numbers in the circle
Step-by-step explanation:
Step-by-step explanation:
In order to find each one, you use the formula A=pi R², meaning you put the radius to the power of two(multiply it by itself) and then multiply that by pi. ex: 7.4×7.4= 54.76,
next 54.76×3.14=171.9, which is your answer. If it gives you the diameter of the circle, divide that by two to get the radius, and follow the steps from before. Ex: 2.24÷2=1.12, next 1.12×1.12=1.2544, next 1.2544×3.14=3.9, the answer.

6. The total cost of materials to build the foam
pit is $1,285.20. What is the cost of materials
per square foot?
Answer:
Cost of Material per square foot = $1.7
Step-by-step explanation:
Given:
Length = 24
Width = 12
Height = 6.5
Find:
Cost of Material per square foot
Computation:
TSA of pit = 2[bh + hl] + lb
TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)
TSA of pit = 2[78+156] + 288
TSA of pit = 756 square foot
Cost of Material per square foot = 1,285.20 / 756
Cost of Material per square foot = $1.7

Based on the end behaviors, which graph is the graph of f(x) = -2x4 − 4x3 + x2 + x + 3?
Given:
The function is
[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]
To find:
The graph of the function by using the end behaviors.
Solution:
We have,
[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]
The degree of the polynomial is 4 which is even and the leading coefficient is -2, which is negative. So,
[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]
[tex]f(x)\to -\infty\text{ as }x\to \infty[/tex]
It means, the graph of the function approaches to negative infinity on the both ends.
Therefore, the correct option is C.

The illustration below shows the graph of y as a function of x.
Complete the following sentences based on the graph of the function.
- As x increases, y _______ (increases/decreases).
- The rate of change for y as a function of x is not __________ (constant/constant), therefore the function is ________ (linear/nonlinear).
- For all values of x, the function value y ___ (≤/≥/=) 0.
- The y-intercept of the graph is the function value y = ____.
- When x = 1, the function value y = ___.
Answer:
As "x" increases "y" *decreases*
y as a function of x is not *constant*
Therefore the function is *nonlinear*
For all values of x, the function value y *≥* 0.
The y intercept of the graph is *8*
x=1 function value of y is *5*
I need to know X for 8 and 10 if u feel like it. PLS
Answer:
8) x=9
10) 23 degrees
Step-by-step explanation:
8) vertical angles are congruent to each other so we can set the expressions as such and solve:
7x + 3 = 10x - 24
3 = 3x - 24
27 = 3x
9 = x
10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for x:
12x + 7 + 6x - 7 = 90
18x + 7 - 7 = 90
18x = 90
x = 5
now we plug it back into the expression equivalent to the measure of angle O:
6(5) -7
30 - 7
23 degrees
A home was purchased in 1985 for $125,000. If the value of the home increased 2.5% each year, what would be the value of the house by 2025? Round to the nearest whole number.
Answer: $335,633
Step-by-step explanation:
First find the number of years difference:
= 2025 - 1985
= 40 years
Use the compound interest formula to find the answer:
= Value * ( 1 + rate) ^ no. of years
= 125,000 * ( 1 + 2.5%)⁴⁰
= $335,633

Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16.
Answer:
See solutions below
Explanation
We are to find the equation of circle A and B
The equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the centre and r is the radius
For Circle A that has center of (6, 7), and a radius of 4
Substitute;
(x-6)^2 + (y-7)^2 = 4^2
(x-6)^2+(y-7)^2 = 16
Hence the equation of circle A is (x-6)^2+(y-7)^2 = 16
For circle B:
If circle B has a center of (2, 4), and a radius of 16
The equation is expressed as;
(x-2)^2+(x-4)^2 = 16^2
(x-2)^2+(x-4)^2 = 256
Hence the required equation is (x-2)^2+(x-4)^2 = 256
Simply (2x^5)^2(4x^3)
I need an answer for this
Answer:
Step-by-step explanation:
18+12+9
Answer:
756 cm^2
Step-by-step explanation:
9 x 12 = 108 triangles
9 x 18 = 162 back side
9^2 + 12^2 = c^2
9^2 + 12^2 = 225
9^2 + 12^2 = 15^2
length of the hypotenuse is 15 so
15 x 18 = 270 slanted top
18 x 12 = 216 bottom
216 + 270 + 162 + 108 = 756 cm^2

Answer:
432 inches.
Step-by-step explanation:
The formula for finding the area of a triangle is;
[tex]\frac{b*h}{2}[/tex]
Using this, we can find the area of each individual piece.
[tex]\frac{6*6}{2} =18[/tex]
Now that we have this, we simply multiply 18 by 24, which gives us 432.

Use the information given to enter an equation in standard form.
(9, 10) and (8, 7) are on the line.
Answer:
The equation in the standard form of the line through the given points is;
y = 3x - 17
Step-by-step explanation:
We start by getting the slope of the line;
m = (y2-y1)/(x2-x1)
m = (7-10)/(8-9) = -3/-1 = 3
The stands equation form is;
y = mx + b
m is slope, b is the y-intercept
so we have
y = 3x + b
To get b, we substitute the coordinates of any of the points
10 = 3(9) + b
10 = 27 + b
b = 10-27
b = -17
So the equation is;
y = 3x - 17
