Ummi's quotients in this situation represent the unit rates of the advertisement
You will not be able to draw a straight line through the points
Part A: What do the quotients represent?From the question, we have the following quotients parameters that can be used in our computation:
2.90/10 = 0.29/1 3.48/12 = 0.29.1 4.48/16 = 0.28.1
These can be rewritten as
2.90/10 = 0.29/1
3.48/12 = 0.29/1
4.48/16 = 0.28/1
The quotients mean that
Unit rate = Total amount spent/Number of adverts
So, the quotient expressions represent the unit rate
Part B: Would you be able to draw a straight line through the points?Recall that
2.90/10 = 0.29/1
3.48/12 = 0.29/1
4.48/16 = 0.28/1
The values of the quotients are not equal
This means that it is not possible to draw a straight line through the points

Jeff bicycles 144 miles at the rate of r mph. The same trip would have taken 3 hours longer if he had decreased his speed by 4 mph. Find r (in mph).
His original speed was r =mph.
Jeff bicycles 144 miles at the rate of r mph. The same trip would have taken 3 hours longer if he had decreased his speed by 4 mph. The value of r is 16.
What is speed ?
The speed at which an object's position changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Given that it only has a direction and no magnitude, speed is a scalar quantity.
144/r= t
144/(r-4)-144/r = 3
LCM r(r-4)
144r-144(r-4)/r(r-4)=3
Simplify [tex]$\frac{144 r-144(r-4)}{r(r-4)}: \frac{576}{r(r-4)}$[/tex]

Let point A be (2,7) and point B be (-6,-3). What point is on the segment connecting A and B such that the distance from the point to B is 4 times the distance from the point to A?
Answer:
The point on the segment connecting A and B that is 4 times as far from B as it is from A is (-8, 8).
Answer:
or the distance to be 4 times the distance from B as A the segment must be divided into (4+1) = 5 segments
so we want the point that is 1/5 of the way from A to B
x from A to B is 2 to - 6 = -8 units 1/5 * -8 + 2 = 0.4
y from A to B is 7 to -3 = -10 units 1/5 * -10 + 7 = 5
A bag contains 10 red marbles, 7 blue marbles, and 3 green marbles. How many blue marbles need to be added to the bag so that the probability of randomly drawing a blue marble is 3/4?.
32 more blue marbles need to be added to the bag so that the probability of randomly drawing a blue marble is 3/4
A bag contains 10 red marbles, 7 blue marbles, and 3 green marbles.
we need to find the numbar of blue marbles need to be added to the bag so that the probability of randomly drawing a blue marble is 3/4
Let the number of blue marbles added be n,
required probability P = 3/4
Total marbles = 10 + 7 + 3
= 20
Number of blue marbles=7
Using definition of probability,
(7 + n)/(20+n) = 3/4
4(7+n)=3(20+n)
28+4n=60+3n
n = 32
Therefore, we need to add 32 more blue marbles to make the probability of randomly drawing a blue marble be 3/4.

how many. roots
f(x) = 4x5 – 3x
The function f(x) is 4x5 – 3x has exactly 5 roots according to the Fundamental Theorem of Algebra.
How to find number of roots ?According to the Fundamental Theorem of Algebra, a polynomial function of degree n has exactly n roots (also known as zeros).In other words, if f(x) is a polynomial function of degree n, then there exist n values of x, called roots or zeros, that satisfy the equation f(x) = 0.The Fundamental Theorem of Algebra is important because it guarantees the existence of solutions to polynomial equations, which are equations that have the form f(x) = 0, where f(x) is a polynomial function.In this case, the polynomial function is f(x) = 4x^5 - 3x, which is of degree 5. Therefore, the function has exactly 5 roots according to the Fundamental Theorem of Algebra.The correct answer is therefore d) 5 roots.

Matias has a planter that is full of soil. The planter is a rectangular prism that is 1 1/2 ft high, 3 2/3 ft long, and 2 ft wide. Matias pours all the soil into a new planter. The new planter is a rectangular prism that has a base of 8 1/4. What is the height of the soil in the new planter
The height of the soil in the new planter is 4/3 feet
Consider the old planter
The height of the prism = [tex]1\frac{1}{2}[/tex] feet = 3/2 feet
The length of the prism = [tex]3\frac{2}{3}[/tex] feet = 11/3 feet
The width of the prism = 2 feet
The volume of the rectangular prism = Length × width × height
= 11/3 × 2 × 3/2
= 11 cubic feet
The area of the base of the new planter = [tex]8\frac{1}{4}[/tex] square feet = 33/4 square feet
The volume of both planter will be equal
The base area × height = volume
33/4 × h = 11
h = 11 / (33/4)
h = 11 × 4/11
h = 4/3 feet
Therefore, the height of the new planter is 4/3 feet

The swimming pool was on sale for $1206.2, which is 18.5% less than its initial $1429.35 cost.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Here,
Sale price after discount=$1206.2
Discount percent=18.5%
Original price=1206.2+18.5%*1206.2

If a car is traveling at 50 mph due south at a point 1 mile north of an intersection. the radar gun register at -62.6 mph.
What is distance?Distance can be defined as how far an object is from another object.
Distance of the first car north of the intersection point =y
Distance of the police car west of the intersection =x
Distance between the cars =s
s² =x² +y²
x=1.4 miles or 0.25 miles
y =1/2 miles or 0.50 miles
Pythagoreans theorem
Distance between cars
s =√x²+y²
s=√(0.25 miles)² +(0.50 miles)²
s =0.559 miles
Hence,
ds/dt = [0.25 miles/ 0.559 miles (-40 mph)] + [0.50 miles/0.559 miles (-50 mph)
ds/dt = -17.89 + -44.7

a) The probability of rolling a total of 5 is 1/9.
b) If a pair of fair dice 360 times, then 40 times you will get a total of 5.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The number of 5 in the table is 4.
The total number of outcomes is 6 × 6 = 36
The number of outcomes of favorable event is 4.
Total number of outcomes is 36.
The probability getting total of 5 after rolling the pair of dice is
