Last year the chess club had 30 members. This year the club has 24 members.
Last year, the chess club had 30 members. This year, the club has 24 members. Since this year had less than last year ( 30 > 24), the percent will be decreasing.
To find the percent decrease, you have to use the following formula.
[tex]\frac{Difference}{Original} \times 100[/tex]
Difference refers to the difference between the two numbers, 24 and 30. The difference between 24 and 30 is 6. Original refers to the original number, which is last year's amount of members in the chess group. Therefore, original = 30.
Substitute the numbers into the formula.
[tex]\frac{Difference}{Original} =\frac{6}{30} =0.2[/tex]
To convert the decimal to a fraction, multiply the decimal by 100.
[tex]0.2 \times 100 = 20 \%[/tex]
The answer is the number of chess members decreased by 20%.
____
Since I started off by identifying whether it was decreasing or increasing, I did the work a bit differently. When finding the difference, you would usually subtract 30 from 24, which results in -6. Above I used 6, but if you used -6, you would end up with a result of -20%, which means it decreased by 20%. They bot end up with the same result, but you don't always have to first identify whether it's decreasing or increasing.
____
Answer:
Decreasing
Step-by-step explanation:
The percentages are decreasing because one year the club had 30 members and the present year has 24 members that decreased by 6!

Frank wants to go bowling. The bowling alley charges $4 per game and a one-time charge of $3 for bowling shoes. Consider the following information. y = 4x + 3y is the total cost of bowling x is the number of games bowled Based on the information, which statement is TRUE?
A. The total cost will increase by $4 for every game bowled.
B. The total cost will increase by $3 for every game bowled.
C. The total cost will increase by $4 for every 3 games bowled.
D. The total cost will increase by $3 for every 4 games bowled.
Answer:
A:The total cost will increase by $4 for every game bowled
Step-by-step explanation:
$4 per game not 3 games or 4 game is per game
The correct statement is:
The total cost will increase by $4 for every game bowled.
What is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
Given:
Total cost of bowling = 4x + 3y
where x is the number of games.
Now, every time the game played they charged it for $4 per game.
So, when there 2 games then the charges will be $8 for two games.
Hence, the correct statement is The total cost will increase by $4 for every game bowled.

The height y (in feet) of a baseball t seconds after it is hit can be modeled by the function y = −16t2 + 96t + 3. About how long does it take to hit the ground?
Answer:
6.03 seconds
Step-by-step explanation:
Given
[tex]y = -16t\² + 96t + 3[/tex]
To solve this, we simply set the height to 0.
i.e. [tex]y = 0[/tex]
So, we have:
[tex]-16t\² + 96t + 3 = 0[/tex]
Solve using quadratic formula.
[tex]t = \frac{-b+-\sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = -16[/tex]
[tex]b = 96[/tex]
[tex]c = 3[/tex]
[tex]t = \frac{-96+-\sqrt{96^2 - 4 * -16 * 3}}{2 * -16}[/tex]
[tex]t = \frac{-96+-\sqrt{9216 +192}}{-32}[/tex]
[tex]t = \frac{-96+-\sqrt{9408}}{-32}[/tex]
[tex]t = \frac{-96+-96.9948452239}{-32}[/tex]
[tex]t = \frac{-96+96.9948452239}{-32}[/tex] or [tex]t = \frac{-96-96.9948452239}{-32}[/tex]
[tex]t = \frac{0.9948452239}{-32}[/tex] or [tex]t = \frac{-192.994845224}{-32}[/tex]
[tex]t = -0.031088913245535[/tex] or [tex]t = 6.0310889132455[/tex]
Since time can't be negative, we have:
[tex]t = 6.0310889132455[/tex]
[tex]t = 6.03\ seconds[/tex] (approximated)

Write an equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis.
The equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis is y=0x+7 or y=7.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
As it is needed that the line must be perpendicular to the y-axis, therefore, the slope of the line will be 0 and the value of y will be 0. Also, it is given that the line passes through (4, 7). Therefore, the equation in slope-intercept form for the line is,
y = mx + c
7 = 0(4) + c
c = 7
Hence, the equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis is y=0x+7 or y=7.

If S = 2(lw + lh + wh) and l = 5w, rewrite the equation for S, substituting in 5w for l.
Answer:
S = 2w( 5w + 6h)
Step-by-step explanation:
given:
S = 2(lw + lh + wh)
if l = 5w, then we simply substitute this into the expression above.
S = 2[ lw + lh + wh ]
S = 2[ (5w)w + (5w)h + wh ]
S = 2[ 5w² + 5wh + wh ]
S = 2( 5w² + 6wh) simplify by factoring out w
S = 2w( 5w + 6h)

If the function f(x)= 2x – 3 and g(x) = 3/2x + 1 then which of the following is a true statement?
f(0) > g(0)
f(8) = g(8)
f(2) = g(2)
g(4) < f(4)
Answer:
f(8) = g(8)Step-by-step explanation:
Given
f(x)= 2x – 3 and g(x) = 3/2x + 1
f(0)= 2(0)-3
f(0) = -3
g(0) = 3/2(0)+1
g(0) = 0+1
g(0) = 1
Hence since -3 < 1, this means that f(0)<g(0)
Also;
f(8)= 2(8)-3
f(8) = 16-3
f(8) = 13
g(8) = 3/2(8)+1
g(8) =12+1
g(8) = 13
This shows that g(8) = g(8)
Hence g(8) = g(8) is a true statement

-5x + 3x +9 = ax + 4 +b
Answer:
a=−b−2x+5/x
Step-by-step explanation:
Step 1: Flip the equation.
ax+b+4=−2x+9
Step 2: Add -b to both sides.
ax+b+4+−b=−2x+9+−b
ax+4=−b−2x+9
Step 3: Add -4 to both sides.
ax+4+−4=−b−2x+9+−4
ax=−b−2x+5
Step 4: Divide both sides by x.
ax/x=−b−2x+5/x
a=−b−2x+5/x

Function f is symmetric around point (4, -1). This point is the minimum of the function f
Step-by-step explanation:
The vertex-form of the quadratic function is y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of its vertex pointThe graph of the quadratic function is a parabola symmetric at the vertex point (h, k), which is the lowest or the highest on the graphIf the vertex is the lowest point then, it is minimum, if it is the highest point, then it is maximumLet us solve the question
→ From the given graph
∵ The graph represents a quadratic function f(x)
∵ It has the lowest vertex
∴ The vertex is minimum
∵ The coordinates of the vertex are (4, -1)
∵ The is symmetric around the vertex point
∴ The function is symmetric around point (4, -1)
Function f is symmetric around point (4, -1). This point is the minimum of the function f
