Consider the first example, 4 hours of parking costs $ 10. From this we can derive the ratio 4 : 10, so that hours parked : fee for parking is a common ratio among the two examples, the other being 5 : 12;
[tex]4 : 10, Simplify\\2 : 5, Take As Fraction,\\Solution; 2 / 5ths\\[/tex]
[tex]5 : 12, Simplify\\( Can't Be Simplified Further ) - Take as Fraction,\\Solution; 5 / 12ths[/tex]
Considering that the fractions when compared are not similar, ( 2 / 5, and 5 / 12 ) they don't have a proportional relationship, and thus have no constant of proportionality
Solution; Not a Proportional Relationship

What would happen if someone sarhpled a basketball team to find the
average height of a school's student body?
Answer:
Basketball players are normally taller so it would not be accurate
Answer: It wouldn't be valid or reliable because the basketball team is not indicitive of the entire student body. Additionally, sampling just the basketball team is not random nor is it likely a large enough sample size (unless it is a tiny school).
Step-by-step explanation:
On their first dive, researchers explore a part of the ocean floor that is 60 feet
below sea level. This depth can be represented by the integer -60. On their
second dive, researchers explore a deeper depth.
Write an inequality that represents the possible depth, d, of the researchers'
second dive.
Answer:
d < -60
Step-by-step explanation:
Let d represent the depth of the researchers' second dive.
Given;
Depth of First dive = -60 ft
It was stated that in their second dive, the researchers explore a deeper depth, That is depth deeper than 60 ft.
Since the depth of 60ft is represented by the integer -60,
Deeper depth would be represented by integers less than -60.
So, d can be represented as;
d < -60
Answer:
d < -60
Step-by-step explanation:
Let d represent the depth of the researchers' second dive.
Depth of First dive = -60 ft
It was stated that in their second dive, the researchers explore a deeper depth, That is depth deeper than 60 ft.
Since the depth of 60ft is represented by the integer -60,
Deeper depth would be represented by integers less than -60.
So, d can be represented as;

A car’s speed before a sudden stop can be estimated by the formula
S = √(30gk) , where
S = speed of the car in mph,
g = drag factor, and
k = length of skid mark in feet.
The drag factor during a recent crash was 1. What was the approximate speed of the car if it created skid marks 30 feet long?
a. 30 mph
b. 45 mph
c. 60 mph
d. 90 mph
Answer:
S = 30 mph
Step-by-step explanation:
A car’s speed before a sudden stop can be estimated by the formula :
[tex]S=\sqrt{30gk}[/tex]
Here,
S = speed of the car in mph,
g = drag factor, and
k = length of skid mark in feet
If drag factor is 1, k = 30 feet
So,
[tex]S=\sqrt{30\times 1\times 30}\\\\S=30\ mph[/tex]
Therefore, the correct option is (a) 30 mph.

In the xy-plane, a line that has the equation y = c for some constant c intersects a parabola at exactly one point . If the parabola has the equation y=-x^ 2 +5x. what is the value of c?
Answer:
c=6.25
Step-by-step explanation:
If a line that is flat (has a slope of zero) hits only one point of the parabola, it means that point is the vertex of the parabola.
In this case your equation is ---
y= –x^2 + 5x
--- and you just need to write in vertex for the equation:
y=a(x–h)^2 + k
y= –(x–2.5)^2 + 6.25
The vertex is (h,k) or (2.5,6.25)
Since the equation is "y=", k=c
or c=6.25

We have to find the point of intersection of the line and the parabola.To do this, we have to apply concepts needed to solve a quadratic equation.Doing this, we find that the value is: [tex]c = \frac{25}{4}[/tex]
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
Line: y = c
Parabola: y = -x^ 2 +5x.
The intersection is at the point:
[tex]-x^2 + 5x = c[/tex]
[tex]-x^2 + 5x - c = 0[/tex]
[tex]x^2 - 5x + c = 0[/tex]
Which is a quadratic equation with [tex]a = 1, b = -5[/tex].
The line and the parabola intersect at exactly one point, which means that the quadratic equation has one solution, that is, [tex]\Delta = 0[/tex].
Since:
[tex]\Delta = b^{2} - 4ac[/tex]
It means that:
[tex]b^2 - 4ac = 0[/tex]
We use this to find the value of c.
[tex](-5)^2 - 4(1)(c) = 0[/tex]
[tex]4c = 25[/tex]
[tex]c = \frac{25}{4}[/tex]
The value is: [tex]c = \frac{25}{4}[/tex]

AB have a 90° angle with BC, so the angles ABD + CBD = 90
(7x - 9)° + 4x° = 90°
7x + 4x = 90 + 9
11x = 99
x = 99/11
x = 9
So the angles are:
7x - 9 -> 7.9 - 9 = 54°
4.9 = 36°
Answer:
m<CBD equals 54
Step-by-step explanation:
Since that is a right angle do (7x-9)+(4x)=90
=11x-9=90
=11x=99
x=9
CBD=7x-9
7(9)-9=54

Dogs in the GoodDog Obedience School win a blue ribbon for learning how to sit, a green ribbon for learning how to roll over, and a white ribbon for learning how to stay. There are 100 dogs in the school.
62 have blue ribbons, 55 have green ribbons, and 63 have white ribbons.
32 have a blue ribbon and a green ribbon 31 have a green ribbon and a white ribbon; 38 have a blue ribbon and a white ribbon.
16 have all three ribbons.
How many dogs have not learned any tricks?
Answer:
5
Step-by-step explanation:
The 32 that have blue and green ribbons include the 16 that have all three, so there are only 32 -16 = 16 that have only blue and green ribbons.
The 31 that have green and white ribbons likewise include the 16 with all three, so there are only 31 -16 = 15 that have only green and white ribbons.
The 38 that have blue and white ribbons include the 16 with all three, so there are only 38 -16 = 22 that have only green and white ribbons.
__
If we add the numbers of blue, green, and white ribbons, we are counting twice the numbers that have 2 ribbons, and 3 times the numbers that have 3 ribbons. We want to count each kind of ribbon-holder only once. Hence the number of individual dogs with any number of ribbons is only ...
62 +55 +63 -(16 +15 +22) -2(16) = 95
Of the 100 dogs, 95 have ribbons, so 5 dogs have not learned any tricks.

A can contains 414 mL of chicken broth. Roland poured 4 cans of broth into a pot for a soup recipe. How many liters of broth did Roland pour into the soup?
Answer:
1.656 litres
Step-by-step explanation:
1 can = 414ml
4 cans = 414 x 4
4 cans = 1,656ml
1,656ml = 1.656 litres
The amount of broth poured into the soup is 1.656 L.
Given data:
To determine the number of liters of broth Roland poured into the soup, we need to convert the volume of the broth from milliliters (mL) to liters (L).
Given that each can contains 414 mL of chicken broth, and Roland poured 4 cans of broth into the pot, we can calculate the total volume in milliliters:
414 mL/can * 4 cans = 1656 mL
On simplifying the equation:
To convert milliliters to liters, we divide by 1000 since there are 1000 milliliters in a liter:
1656 mL / 1000 = 1.656 L
Hence, Roland poured 1.656 liters of broth.

Answer:
see below
Step-by-step explanation:
1.
m = (y2-y1)/(x2-x1)
= (90-80)/(0-1)
= 10/-1
=-10
The slope is -10 ft/s
This means the height decreases 10 ft for every second that passes
This is not proportional because it has to go through the point (0,0)
4.
m = (y2-y1)/(x2-x1)
= (1000-0)/(3-0)
= 1000/3
=1000/3
The slope is $1000/3
This means the 1000 dollars is sold every 3 days
This is proportional because it goes through the point (0,0) and has a constant slope
Step-by-step explanation:
Let 'm' be slope
HAWK DIVING TOWARDS PREY:
m = (y2 - y1) / (x2 - x1)
= (90 - 80) / (0 - 1)

A.The easiest to solve for is x in the first equation.
B.The easiest to solve for is y in the first equation.
C.The easiest to solve for is x in the second equation.
D.The easiest to solve for is y in the second equation.
Answer:
BStep-by-step explanation:
y in equation 1, since you just
-4x + y = 6
add 4x to both sides to get
y = 4x + 6
while for the rest of the variables in both equations, you need at least two steps
Thus, the answer is B
Answer:
B. The easiest to solve for is Y in the first equation.
Step-by-step explanation:
Since the y has no coefficient in both equations, we look at the steps we take to solve. Equation 2 has to make you multiply negative one by both sides to make y positive, and THEN you would have to subtract 5x from both sides. However, with the first equation, all we need to do to solve for Y is add 4x to both sides. The answer? B. The easiest to solve for is Y in the first equation.
