Answer:
Let's define the variables:
M = # of miles that Nora jogs on Monday
T = # of miles that Nora Jogs on Tuesday
We know that:
"Nora jogs 414 miles on Monday"
Then we have:
M = 414 mi
"She jogs 112 fewer miles on Tuesday"
This can be written as:
T = M - 112 mi
This is the equation that we need to solve.
Here we can simply replace the value of M by 414mi and get:
T = 414 mi - 112 mi = 302 mi.
Nora jogs 302 miles on Tuesday.

The radius of the puddle is zero when time is zero but expands at a rate of one-quarter unit per second instead of one-half unit per second. By what factor does the denominator of the resultant composite function A(r(t)) change from that in the opening scenario?
Given that the radius of the puddle expands, originally, at a rate of 1/4 unit/second instead of 1/2 unit/second.
The current rate of expension of the radius,
\frac {r(t)}{t}=frac 1 4 unit/second ...(i)
The resultant composite function is area, A(r(t)).
The area of a circular region having radius r is,
[tex]A(r)=\pi r^2[/tex]
If the radius is the function of time, then the composite function is
[tex]A(r(t))=\pi \(r(t))^2[/tex]
To determine the rate of change of area with respect to time, differentiate the composite function A(r(t)) once with respect to time, we have
[tex]\frac {d\{A(r(t))\}}{dt}=\pi \left(2\frac {d\{r(t)\}}{dt}\right)[/tex]
So, the composite function is changing twice of the rate of change of the radius.
By using equation (i), if r(i) is changing with R= 1/4 unit / second.
Then, A(r(t)) will change 2 x 1/4 = 1/2 square unit/second.

Jonathan draws a ticket from a box to select the door prize winners at a party. The tickets are numbered from 1 to 25. What is the expected value that the tickets drawn will have numbers less than 5 if he draws tickets 40 tickets
Answer:
6
Step-by-step explanation:
Given that there are tickets in the draw which are numbered from 1 to 25.
Probability of an event E is given by the formula:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Probability of each number can be found out as:
Number of favorable cases for each number is 1 and total number of cases here is equal to the total number of tickets i.e. 25.
[tex]P(Each\ Number) = \dfrac{1}{25}[/tex]
Now, the numbers less than 5 mean 1, 2, 3 and 4.
Therefore, 4 number of favorable cases.
[tex]P(1, 2, 3\ or\ 4) = \dfrac{4}{25}[/tex]
Now, it is given that 40 tickets are drawn.
Number of times, the numbers less than 5 are expected:
[tex]\dfrac{4}{25}\times 40 \approx 6[/tex]

The points on a section of an exam is given by the function f (x) , where x is the number of questions answered correctly in that section. If f (12) = 18 , then a test-taker receives 18 points for answering _____ questions in the section correctly.
Answer:
The answer is "12"
Step-by-step explanation:
Let f(x) be the function, where x specified in a certain section by the series of queries that have been addressed also as function.
[tex]\to f(12)=18[/tex] it implies, that even a test the person gets 18 points to packed up x queries. Its right series of issues were also:

The side length of a square launch pad is 11 centimeter.
Here,
Darius is building a square launch pad for a rocket project.
The area of the pad is 121 square centimeters.
We have to find, it's side length.
What is Area of square?
The area of a square = side x side
Since each side of a square is the same, it can simply be the length of one side squared.
Now,
The area of the pad is 121 square centimeters.
We use the area formula,
⇒[tex]A = s^{2}[/tex]
⇒ [tex]s^{2} = 121[/tex]
⇒[tex]s = \sqrt{121}[/tex]

Find a point-slope form for the line with slope 1/5 and passing through the point (-8, - 9).
The equation of the line in point-slope form is ______?
Answer:
y=1/5(x+8)-9
Step-by-step explanation:
Point Slope Formula: y=m(x-x1)+y
y=1/5(x+8)-9
Answer:
[tex]y+9=\frac{1}{5} (x+8)[/tex]
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of 1/5, and passes through the point (-8, -9).
We want to write the equation of this line in point-slope form.
Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.
Pre-SolvingAs we are given both the slope and the point, we can plug those values into the equation.
Starting with the slope, we can replace m with 1/5.
[tex]y-y_1=\frac{1}{5} (x-x_1)[/tex]
Now, substitute -8 as [tex]x_1[/tex] and -9 as [tex]y_1[/tex]. We get:
[tex]y--9=\frac{1}{5} (x--8)[/tex]
This can be simplified to:
[tex]y+9=\frac{1}{5} (x+8)[/tex]

Lily sold 5 purses in her first week of business and 15 purses in her second week of business.If p represents the profit she makes from selling one purse, how could lily write and simplify a variable expression that represents her current profit after two weeks in business?
Answer:
20p = x
Step-by-step explanation:
Since Lily sold 5 purses in week one and 15 purses in week two that adds up to be a total of 20 purses sold in two weeks. Since p represents the profit for each purse she can use the expression below which simply multiplies the profit per purse (p) by the total amount of purses sold in the two weeks which would give her the total amount of profit (x) that she made from all of her sales.
20p = x

The field inside a running track is made up of a rectangle 84.39m (meters) long and 73m (meters) wide, together with a half-circle at each end. The running lanes are 9.76m (meters) wide all the way around. Question: What is the area of the running track that goes around the field? Explain or show your reasoning.
Answer:
3886.53 [tex]m^{2}[/tex]
Step-by-step explanation:
The running track consist of two semicircles and a rectangle.
So that;
Diameter of the semicircles = width of the rectangle = 73 m
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{73}{2}[/tex]
= 36.5 m
But the two semicircles form a circle, so that;
Circumference of a circle = 2[tex]\pi[/tex]r
Circumference of the circle formed by the semicircles = 2 x [tex]\frac{22}{7}[/tex] x 36.5
= 229.43 m
Thus,
length of the running track = circumference of the circle formed + length of the two sides of the rectangle
= 229.43 + 84.39 + 84.39
= 398.21 m
The length of the running track is 398.21 m.
Therefore;
Area of the running track = length x width
= 398.21 x 9.76
= 3886.5296
The area of the running track is 3886.53 [tex]m^{2}[/tex].
