Answer:
6,265 votes
Step-by-step explanation:
The residents of a city voted on whether to raise property taxes. The ratios of yes votes to no votes was 5 to 7. If there were 10,740 total votes, how many no votes were there?
Given that :
Ratio of yes votes to no votes = 5 to 7
Yes votes : no votes = 5 : 7
Total votes = 10,740
The actual number of yes votes and no votes can be obtained thus :
Sum of ratio = (5 + 7) = 12
(ratio of vote / sum of ratio) * total votes
Number of no votes :
(Ratio of no votes / total ratio) * total votes
(7 / 12) * 10,740
0.5833333 * 10,740
= 6,265 votes
Number of no votes = 6,265 votes.
Which is an equation of the line through (-1,-4) and parallel to the line 3x + y = 5?
Answer: y = -3x -7 or 3x + y = -7
Step-by-step explanation:
For two lines to be the same, they need to have the same slopes but different y-intercepts. First convert the equation 3x+y =5 into slope intercept form.
3x + y = 5 subtract 3x from both sides
-3x -3x
y = -3x + 5 in this case we know that the slope is -3 and the y-intercept is 5.
Now since they will have the same slope input the x and y coordinates and find the equation that will be parallel to it.
-4 = -3(-1) + b
-4 = 3 +b
-3 -3
b= -7
Since the y intercept is -7 the equation will be y = -3x -7 or 3x + y = -7
Equation of the line through (-1,-4) and parallel to the line 3x + y = 5 is
3x + y + 7 = 0
What is slope intercept form?The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as:
y = mx + b.
Given, equation of line
3x + y = 5
y = -3x + 5
Comparing to y = mx+c
slope m = -3
slope of parallel lines are equal
∴ slope m' of the line which passes through (-1,-4) is -3
Equation of the line
y-(-4) = m'(x - (-1))
y + 4 = -3x - 3
y = -3x - 7
3x + y + 7 = 0
Hence, 3x + y + 7 = 0 is the equation of the line passing through (-1,-4) and parallel to 3x + y = 5.

Find the area of the shaded region . RQ= 71.5 inches and PO=93.4 inches . Use 3.14 as necessary
Answer:
25,886.01 in²
Step-by-step explanation:
The area of shaded region = Area of the outter circle (the larger circle) - area of the inner circle (the smaller circle)
Area of a circle = πr²
Radius of larger circle = PO = 93.4 in
Area of the larger circle = 3.14*93.4² = 27,391.98 in²
Radius of smaller circle = PO - RQ = 93.4 - 71.5 = 21.9
Area of smaller circle = 3.14*21.9² = 1,505.97 in²
Area of shaded region = 27,391.98 - 1,505.97 = 25,886.01 in²

How many real solutions does the equation 2p^2 + 9p - 7 = 0 have?
A. 0
B. 1
C. 2
D. 3
Answer:
C
Step-by-step explanation:
Determine the nature of the solutions using the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct solutions
• If b² - 4ac = 0 then 2 real and equal solutions
• If b² - 4ac < 0 then no real solutions\
Given
2p² + 9p - 7
with a = 2, b = 9, c = - 7 , then
b² - 4ac = 9² - (4 × 2 × - 7) = 81 +56 = 137
Since b² - 4ac > 0 then there are 2 real solutions → C
Answer:
C. 2
Step-by-step explanation:
2p² + 9p - 7 = 0
p = {-9±√((9²)-(4*2*-7))} / (2*2)
p = {-9±√(81+56)} / 4
p = {-9±√137} / 4
p = {-9±11.7} / 4
p₁ = {-9-11.7} / 4 = -20.7/4 = -4.55 aprox.
p₂ = {-9+11.7} / 4 = 2.7/4 = 0.67 aprox.
This equation have 2 real solutions:

Between which two integers on a number line does -√120 lie on?
Answer:
-11 and -10
Step-by-step explanation:
● -√120 = -1 × √120
● -√120 = -1 × 2√30
● 30 is close to 25 so √30 is close to five but greater than it.
Multiplying 5 by -2 gives -10
Multipluing √30 by -2 gives you a number that is close to -10 but smaller than it.
So -√120 lies between -11 and -10
The addition formula for cosine is shown below.
Answer:
Step-by-step explanation:

Cos(A+B) = 6/10 * 15/17 - 8/10 * 8/17
Cos(A +B) = 90/170 - 64/170
Cos(A + B) = 26/170

0. A submarine was at sea level and
then dove 752 ft. It then rose at a rate
of 12 ft. per minute. What was the
depth of the submarine after 8
minutes?
Also idk the equation so if u could help me out with that id be grateful
One equation you can use is y = -12x+752 and you plug in x = 8 to find y.
=================================================
Explanation:
x = number of minutes
y = depth of the submarine
Being at sea level means the depth is y = 0. Diving 752 ft below sea level means the depth is y = 752. It's tempting to make this negative since we're below sea level, but depth values are always positive. They are simply distances you are from the surface of the water. Negative distances are never possible. So this concept might be a bit tricky to get used to.
Possibly equally confusing is the fact that the "12 ft per minute" means the slope is -12. This is because the depth is getting smaller as the submarine gets closer to the surface (aka the sub is rising).
The equation is y = -12x+752. The equation is in the form y = mx+b with m = -12 as the slope and b = 752 as the y intercept. Note how the y intercept is the starting depth value.
From here, we plug in x = 8 to find where the sub is
y = -12x+752
y = -12*8+752
y = -96+752
y = 656
The submarine's depth after eight minutes is 656 feet
----------------------
An alternative equation to use is
y = 12x-752
which is very similar to the other one used earlier. All I did was flip the sign of each term. Now y represents the height of the sub. Negative y values indicate we're below the surface of the water. The slope being positive means the submarine is going upward. The negative y intercept indicates we're starting 752 feet below sea level. Plugging in x = 8 will lead to y = -656, which you'll need to make positive (since all depth values are positive).
As you can probably guess, the change from y = -12x+752 and y = 12x-752 is simply multiplying the right hand side by -1, which explains why the signs flip (and explains how the y value sign flips as well)

Step-by-step explanation:
[tex]\frac{3x}{x-4}+\frac{x-3}{2x}[/tex]
Make them into common denominators. To do so, multiply by the LCM of the denominators. The LCM of the denominators is (x-4)(2x). Thus, we multiply 2x to the first term and (x-4) to the second:
[tex](\frac{2x}{2x}) \frac{3x}{x-4}+(\frac{x-4}{x-4}) \frac{x-3}{2x}[/tex]
Simplify:
[tex]\frac{6x^2}{2x(x-4)}+\frac{x^2-7x+12}{2x(x-4)} \\=\frac{7x^2-7x+12}{2x(x-4)}[/tex]
And this cannot be simplified further (you can also distribute the denominator if preferred).
If the function 5x + y = 1 has the domain {-2, 1, 6}, then what is the corresponding range?
Answer:
{ 11, -4, -29}
Step-by-step explanation:
5(-2) + y = 1
-10 + y = 1
y = 11
5(1) + y = 1
y = -4
5(6) + y = 1
30 + y = 1
y = -29
Answer:
The Range is the set: { -29, -4, 11 }
Step-by-step explanation:
You need to apply the given function to the x-values of the Domain, to find what values of the Range they are associated with. So let's start by isolating y on one side of the expression:
y = 1 - 5 x
Now let's find what values they result when x = -2, 1, and 6:
y = 1 - 5 (-2) = 1 + 10 = 11
y = 1 - 5 (1) = 1 - 5 = -4
y = 1 - 5 (6) = 1 - 30 = -29
Therefore the Range is the set: { -29, -4, 11 }

A building meets the ground at a right angle. The top of a 10-foot ladder is placed against the bottom edge of a window in the building, and the base of the ladder is placed 6 feet from where the building meets the ground. Could you use lines and text to draw and label a diagram that represents this situation?
Greetings from Brasil...
Its attached the diagram of the situation.....
The ground is 8 feet from the bottom edge of the window
How far up from the ground is the bottom edge of the window?We start by representing the building, the ladder and the ground in a sketch.
See attachment for diagram
From the diagram, the distance (d) from ground to the bottom edge of the window is calculated using Pythagoras theorem:
10^2 = d^2 + 6^2
Evaluate the squares
100 = d^2 + 36
Evaluate the like terms
d^2 = 64
Take the square root of both sides
d = 8
Hence, the ground is 8 feet from the bottom edge of the window

Answer:
∠ G = 121°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + 3x + 25 + x - 5 = 180 , that is
5x + 20 = 180 ( subtract 20 from both sides )
5x = 160 ( divide both sides by 5 )
x = 32
Thus
∠ G = 3x + 25 = 3(32) + 25 = 96 + 25 = 121°
