The city council voted on a new tax. 19 council members voted in favor of the tax. The council has 38 members. What percentage of the council members voted in favor of the tax? Write your answer using a percent sign (%).
Answer:
50%
Step-by-step explanation:
Given parameters:
Number of those who voted in favor of the tax = 19
Total member of the council = 38
Unknown:
Percentage of council members that voted in favor of the tax = ?
Solution:
To find the percentage of those that voted in favor;
= \(\frac{number of those that voted in favor}{Total number of council members } x 100\)
Input the parameters and solve;
= \(\frac{19}{38}\) x 100
= 50%

*This answer may be wrong (part a), so make sure to double check with someone trustworthy. Feel free to tell me if I had made any mistakes, and I will fix them. Congrats if you read through my whole answer! Good luck!
Answer (a):
Coordinate: (0, 65)
Slope: -25
Step-by-step explanation:
Hint: In the graph, make one space represent 5 units to make the graph simpler (be careful on step #4 when plotting)
1.) Find the y - intercept to find a coordinate the line goes through.
2.) Rewrite the equation -25x + y = 65 in slope - intercept form.
y = 25x + 65
65 is the y - intercept at (0, 65)
3.) The slope is -25, so the slope is negative. To have a slope of 25, we can use the rise/run formula for the slope.
4.) Go 25 units to the left (to get to -25) and one unit down. Plot this point in the graph.
5.) After you have plotted these two points down (y - intercept and slope), draw a line through it.
Answer (b):
$140
Step-by-step explanation:
1.) We plug in 3 in x because it has three charms.
2.) New equation: -25(3) + y = 65
-75 + y = 65
3.) We add 75 to both sides to isolate y.
-75 + y = 65
+75 + y = 65 + 75
y = 140

Let S(x)= n, if n is less than x is less than n+1 for every integer n, be the staircase function. Note that S(x) is riddled with discontinuities on suitably large domains. Let M, N, be two arbitrary positives integers subject to 0 is less than M is less than N. Determine a formula in terms of M and N for the integral of S(x)dx from m to n. Solve using improper integrals and sigma notation.
Please help, I am having trouble with this question.
The staircase function S(x) takes on the value of the largest integer less than x. To find the integral of S(x) over an interval [M, N], we can consider the area under the staircase function over each subinterval [n, n + 1] for integers n such that M <= n <= N.
The area under S(x) over the subinterval [n, n + 1] can be represented as a rectangle with height n and width 1. Therefore, the integral of S(x) over the subinterval [n, n + 1] is given by n.
Using sigma notation, we can represent the integral of S(x) over the interval [M, N] as follows:
∫_M^N S(x)dx = ∑_{n=M}^{N-1} ∫_n^{n+1} n dx = ∑_{n=M}^{N-1} n * (n+1 - n) = ∑_{n=M}^{N-1} n = (M + (M + 1) + ... + N-1) = (N^2 - M^2)/2.
So, the integral of the staircase function S(x) over the interval [M, N] is equal to (N^2 - M^2)/2.

How to solve an equation?An equation is an expression that can be used to show the relationship between two or more numbers and variables using mathematical operators.
The area of a figure is the amount of space it occupies in its two dimensional state.
The length of an arc with an angle of Ф is given by:
Length of arc = (Ф/360) * (π * diameter)
The diameter is 16 cm and intercepted arc length is 6 cm, hence:
Length of arc = (Ф/360) * (π * diameter)
6 = (Ф/360) * (π * 16)
Ф = 42.97°
Ф = 42.97° * π/180 = 0.75 radian
The measure of the central angle is 0.75 radians

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region.
y=6x^2 , y=x^2+6
The area of the region enclosed by the curves y=6x² and y=x²+6 is 8.76 unit square and has been drawn.
What is definite integral mean?The definite integral of a function over a limit represents the area under the curve bounded by the limit as given in integration.
As per the given curves,
y=6x² and y=x²+6
The above curves have been drawn.
The intersection points can be calculated by equating both equations as (-1.095,7.2) and (1.095,7.2).
The area enclosed will be as follows,
Area = \(\int\limits^{1.095}_{-1.095} {[(x^{2}+6)-6x^{2}]} \, dx\)
A = - 5/3[1.095³ + 1.095³] + 6[1.095 + 1.095]
A = 8.76 unit square.
Hence "8.76 unit squares make up the region that is encompassed by the curves y=6x² and y=x²+6".

Work out the volume of the prism height of 12 4 and five
The calculated volume of the prism is 702 cubic cm
Finding the volume of the prismFrom the question, we have the following parameters that can be used in our computation
The trapezoidal prism (see attachment)
The formula of the volume of a trapezoidal prism is
Volume = Base area * Height
Where we have
Base area = 1/2 * (8 + 10) * 6
Evaluate the sum of 8 and 10
Base area = 1/2 * 18 * 6
Evaluate the products of 1/2, 18 and 6
Base area = 54
Also, we have
Height = 13
So, the volume is calculated as
volume = 13 * 54
Evaluate
volume = 702
Hence, the volume of the prism is 702 cubic cm

When the simultaneous equation is solved, we have that; x = 2 and y = 3
What is the solution to a simultaneous equationSimultaneous equations are a set of two or more equations that are solved together to find the values of the variables that satisfy all of the equations at the same time.
We have the equations;
9x - 7y = -3 --- (1)
-3x + 5y = 9 ---- (2)
Multiply (1) by 1 and (2) by (3)
9x - 7y = -3 ---- (3)
-9x + 15y = 27 ----- (4)
Add (3) and (4)
8y = 24
y = 3
Substitute y = 3 into (1)
9x - 7(3) = -3
9x - 21 = -3
9x = -3 + 21
9x = 18
x = 2
Thus the solution is x = 2 and y = 3
