On a 1 mile track, Runner A has made 18 laps in the time it took Runner B to make 8 laps. If Runner A is running 5 mph faster than Runner B, how fast is each of them running?
9514 1404 393
Answer:
A: 9 mphB: 4 mphStep-by-step explanation:
Let b represent the speed of runner B. then the ratio of speeds is ...
b/(b+5) = 8/18
18b = 8(b +5) . . . . cross multiply
10b = 40 . . . . . . . . subtract 8b
b = 4 . . . . . . . . . . . divide by 10
Runner B's speed is 4 mph; runner A's speed is 5 mph more.
Runner A is running at 9 mph; Runner B is running at 4 mph.

What is the value of the expression below when x = 4
2x² + x – 5
Find the value of c so that the polynomial p(x) is divisible by (x – 3).
p(x) = -x3 + cx2 - 4x + 3
с=
Answer:
c = 4
Step-by-step explanation:
p(x) is divisible by (x - 3).
So, p(3) = 0
-(3)³ + c(3)² - 4 *3 + 3 = 0
-27 + 9c - 12 + 3 = 0
9c - 36 = 0
9c = 36
c = 36/9
c = 4

A line segment AB has the coordinates A (2,3) AND B ( 8,11) answer the following questions (1) What is the slope of AB? (2) What is the length of AB? (3) What are the coordinates of the mid point of AB?(4) What is the slope of a line perpendicular to AB ?
Answer:
(1) The slope of the line segment AB is 1.[tex]\bar 3[/tex]
(2) The length of the line segment AB is 10
(3) The coordinates of the midpoint of AB is (5, 7)
(4) The slope of a line perpendicular to the line AB is-0.75
Step-by-step explanation:
The coordinates of the line segment AB are;
A(2, 3) and B(8, 11)
(1) The slope of a line segment is given by the following equation;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) and (x₂, y₂) are two points on the line segment
Therefore;
The slope, m, of the line segment AB is given as follows;
A(2, 3) = (x₁, y₁) and B(8, 11) = (x₂, y₂)
[tex]Slope, \, m_{AB} =\dfrac{11-3}{8-2} = \dfrac{8}{6} = 1 \frac{1}{3} = 1.\bar3[/tex]
The slope of the line segment AB = 1.[tex]\bar 3[/tex]
(2) The length, l, of the line segment AB is given by the following equation;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Therefore, we have;
[tex]l_{AB} = \sqrt{\left (11-3 \right )^{2}+\left (8-2 \right )^{2}} = \sqrt{64 +36} = 10[/tex]
The length of the line segment AB is 10
(3) The coordinates of the midpoint of AB is given as follows;
[tex]Midpoint, M = \left (\dfrac{x_1 + x_2}{2} , \ \dfrac{y_1 + y_2}{2} \right )[/tex]
Therefore;
[tex]Midpoint, M_{AB} = \left (\dfrac{2 + 8}{2} , \ \dfrac{3 + 11}{2} \right ) = (5, \ 7)[/tex]
The coordinates of the midpoint of AB is (5, 7)
(4) The relationship between the slope, m₁, of a line AB perpendicular to another line DE with slope m₂, is given as follows;
[tex]m_1 = -\dfrac{1}{m_2}[/tex]
Therefore, the slope, m₁, of the line perpendicular to the line AB, that has a slope m₂ = 4/3 = 1.[tex]\bar 3[/tex] is given as follows;
[tex]m_1 = -\left (\dfrac{1}{\frac{4}{3} } \right ) = -\dfrac{3}{4} = -0.75[/tex]
The slope, m₁, of the line perpendicular to the line AB is m₁ = -0.75.
Determine if the sequence is arithmetic write yes or no 5,9,14,20
Answer: No
Step-by-step explanation:
An arithmetic sequence is one where the same number is being added to the number before it. For example, 2, 4, 6, 8..., where 2 is being added to each number.
In this case, however, the number being added is not consistent with this pattern. Between 5 and 9, the difference is 4 and between 9 and 14, the difference is 5, and so forth. This pattern does not follow the rules of an arithemtic sequence.

What equation in Slope-Intercept Form represents the line that passes through the points ( -3,3) and ( 1,2)?
Answer:
[tex]y=-\frac{1}{4}x+\frac{9}4}[/tex]
Step-by-step explanation:
Answer:
Step-by-step explanation:
(x₁ , y₁) = (3, -3) & (x₂ , y₂) = (1 , 2)
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{2-3}{1-[-3]}\\\\= \frac{-1}{1+3}\\\\=\frac{-1}{4}[/tex]
m = (-1/4)
y - y₁ = m(x - x₁)
[tex]y - 3 = \frac{-1}{4}(x - [-3])\\\\y - 3 = \frac{-1}{4} (x + 3)\\\\y - 3 = \frac{-1}{4}x-\frac{3}{4}\\\\ y = \frac{-1}{4}x-\frac{3}{4} + 3\\\\ y =\frac{-1}{4}x+\frac{-3+12}{4}\\\\ y =\frac{-1}{4}x+\frac{9}{4}[/tex]

A 10,000-gallon swimming pool needs to be emptied. Exactly 2,000 gallons have already been pumped out of the pool and into the tanker. As the pump is pumping water, the amount of water in the pool decreases at a constant rate of 720 gallons per hour. What is the slope and what is the y-intercept
Answer:
slope = -720
y-intercept: 8,000
Step-by-step explanation:
The slope in this case is a negative slope, since the word "decreased" is being used. The rate of 720 gallons per hour can be seen as -720 / 1, which gives you the -720 slope.
The y-intercept in an equation represents the initial value. Since 2,000 gallons has already been pumped out, the initial value is 8,000.
The constant rate at which the water decreases results in a straight line
function between the volume of water in the tank and time of pumping.
The slope is -720 (gal/hour)
The y-intercept is 8,000 (gallons)
Reasons:
The volume of the swimming pool = 10000 gallon
Volume of water already pumped out = 2,000 gallons
Rate at which the water is being pumped out = 720 gallons per hour
Required:
The slope and y-intercept of the function
Solution:
Volume of water in the tank = (10,000 - 20,000) gallons = 8,000 gallons
Volume of water decreasing from the tank after t hours = 720·t
Therefore;
Volume of water in the tank after t hours, is V(t) = 8000 - 720·t
Comparing the above function with the equation of a straight line, in slope
and intercept form, y = m·x + c, we have;
V(t) = -720·t + 8000
Slope, m = -720y-intercept = 8000Learn more here:

A two-day moving truck rental from Best Rentals costs $60 and $0.35 per mile driven. A two-day moving truck rental from Easy Movers costs $80 and $0.25 per mile driven. Let m represent the number of miles driven. Which equation can be used to find the number of miles for which the rentals would cost the same amount? 60 + 0.35 m = 80 + 0.25 m 60 m + 0.35 = 80 + 0.25 m 60 + 0.35 m = 80 m + 0.25 m 60 m + 0.35 = 80 m + 0.25

From 2010 to 2011, the population of Queens increased by 16,075. Brooklyn's population increased by 11,870 more than the population increase of Queens. a) Estimate the total combined population increase of Queens and Brooklyn from 2010 to 2011. (Round the addends to estimate.)
Answer: 44000
Step-by-step explanation:
From the question, we are informed that the population of Queens increased by 16,075.
Brooklyn's population increased by 11,870 more than the population increase of Queens. This means that Brooklyn's population will be:
= 16075 + 11870
= 27945
The total combined population increase of Queens and Brooklyn from 2010 to 2011 will then be:
= 16075 + 27945
Estimating 16075 gives 16000
Estimating 27945 gives 28000
Adding then together equals
16000 + 28000 = 44000

Please help I don't want just the answer I want to know how to solve it.
Answer:
149 degrees
Step-by-step explanation:
Since m and n are parallel you need to remember the rules of transversals, this means that <1 and <2 are corresponding. Corresponding angles are always congruent, so we can solve for x by setting them equal to each other.
[tex]8x-1=7x+3[/tex]
First, move the variables to one side, I will move them both to the right, but remember you can do it on either side. To do this subtract 7x from both sides
[tex]8x-1-7x=7x+3-7x[/tex], then simplify
[tex]x-1=3[/tex]
Next, add 1 to both sides to isolate the variable
[tex]x-1+1=3+1[/tex], then simplify
[tex]x=4[/tex]
Now that you know what x equals solve for angle 1, to do this plug 4 in for x in the original equation
[tex]8(4)-1=31[/tex]
Finally, you can solve for <3 because <1 and <3 are supplementary. So to solve add both and set them equal to 180, in this equation let x stand for <3. [tex]180=31+x[/tex], then subtract 31 from both sides [tex]180-31=31+x-31[/tex] and simplify, [tex]149=x[/tex]. So angle 3 is equal to 149.
