Madison and Franklin are 6 in apart on a
map that has a scale of 1 in: 7 mi. How
far apart are the real cities?
Final answer:
The actual distance between Madison and Franklin is 42 miles.
Explanation:
To find the actual distance between Madison and Franklin, we can use the given scale of 1 in: 7 mi. Since Madison and Franklin are 6 inches apart on the map, we can multiply the scale by the number of inches to find the distance in miles.
Distance in miles = Scale x Number of inches apart = 7 mi/in x 6 in = 42 miles
Therefore, the actual distance between Madison and Franklin is 42 miles.

List the angles of the triangle in order from smallest to largest measure.
Answer:
G, I, H
Step-by-step explanation:
6 and 4 force H to be the largest and G to be the smallest.
For any right triangle, the 90 degree angle is always the largest. The longest side of a triangle is always opposite the largest angle. Similarly, the shortest side of a triangle is always opposite the smallest angle.
Angle G is opposite side HI = 4 which is the smallest side, so angle G is the smallest angle.
Angle H is the middle angle as this is the longer leg, but it is not longer than the hypotenuse. The hypotenuse is always the longest side.

If f(1) =7 and f(n)=-5f(n-1)-n
then find the value of
f(4)
Final answer:
Using the recursive relationship f(n) = -5f(n-1) - n, we calculated the values step by step to find that f(4) is -914.
Explanation:
The question asks us to find the value of f(4) given that f(1) = 7 and the recursive relationship f(n) = -5f(n-1) - n.
To find f(4), we need to compute it in a step-by-step manner by first finding f(2) and f(3), and using those results to finally compute f(4).
Starting with f(1) = 7, we calculate f(2):
f(2) = -5f(1) - 2 = -5*7 - 2 = -35 - 2 = -37.
Next, calculate f(3):
f(3) = -5f(2) - 3 = -5*(-37) - 3 = 185 - 3 = 182.
Finally, calculate f(4):
f(4) = -5f(3) - 4 = -5*182 - 4 = -910 - 4 = -914.
Therefore, the value of f(4) is -914.
Final answer:
Using the recursive function given, by computing step by step from f(1) up to f(4), we find that f(4) equals -914.
Explanation:
To find the value of f(4), we must use the given recursive relation f(n) = -5f(n-1) - n, starting with the base case f(1) = 7.
Find f(2):Therefore, f(4) = -914.

A wheel completes 2.4 revolutions in 3 seconds.
What is the angular velocity of the wheel in radians per minute?
State your answer in exact form as a simplified fraction.
Answer:
The angular velocity of the wheel in radians per minute is 96·π·rad/min
Where π = 22/7 then the angular velocity is [tex]301\frac{5}{7} \ rad/min[/tex]
Step-by-step explanation:
The number of revolutions completed per 3 seconds = 2.4 revolutions
∴ The number of revolutions completed per second = 2.4/3 = 0.8 = 4/5 revolutions
The angle per revolution = 2π radians
∴ Angular velocity per second = 0.8×2×π rad/sec
The angular velocity of the wheel in radian per second = 1.6·π·rad/sec
1 minute = 60 Seconds
∴The angular velocity of the wheel in radians per minute = 96·π·rad/minute
Where π = 22/7 then the angular velocity = [tex]301\frac{5}{7} \ rad/min[/tex].

The values of x and y vary directly and one pair of values are given. Write an equation that relates x and y. x=-4,y=6
Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
Given that x varies directly with y, if we introduce a constant of proportionality, k, the expression becomes
x = ky
If x = - 4 when y = 6, then
- 4 = 6k
k = - 4/6 = - 2/3
Therefore, the equation that relates x and y is
x = -2y/3
Answer:

A park planner is designing a dog park. He wants to use a metal fence to enclose a kennel at the dog park. The vertices of the fence are shown below. The units on the coordinate plane are yards.
Point A (4,-4)
Point B (-4,-4)
Point C (-4,3)
Point D (1,3)
Point E (1,-1)
Point F (4,-1)
The park planner wants to add a gate between points A and F. He will not put metal fencing on that side. What is the total number of yards of metal fencing that will be needed for the kennel at the dog park?
The total number of yards of metal fencing needed for the kennel at the dog park is 27 yards.
The fence segments are determined by the vertices A, B, C, D, E, and F. The distances between consecutive vertices can be calculated using the distance formula:
[tex]\[ \text{Distance} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \][/tex]
Let's calculate the lengths of the segments:
1. Length of AB: [tex]\(\sqrt{(-4 - 4)^2 + (-4 - (-4))^2} = \sqrt{64 + 0} = 8\) yards[/tex]
2. Length of BC: [tex]\(\sqrt{(-4 - (-4))^2 + (3 - (-4))^2} = \sqrt{0 + 49} = 7\) yards[/tex]
3. Length of CD: [tex]\(\sqrt{(1 - (-4))^2 + (3 - 3)^2} = \sqrt{25 + 0} = 5\) yards[/tex]
4. Length of DE:[tex]\(\sqrt{(1 - 1)^2 + (-1 - 3)^2} = \sqrt{0 + 16} = 4\) yards[/tex]
5. Length of EF: [tex]\(\sqrt{(4 - 1)^2 + (-1 - (-1))^2} = \sqrt{9 + 0} = 3\) yards[/tex]
Now, sum up these lengths:
[tex]\[ 8 + 7 + 5 + 4 + 3 = 27 \][/tex]
So, the total number of yards of metal fencing needed for the kennel at the dog park is 27 yards.

What is the cartesian plane?The cartesian plane is a two-dimensional coordinate plane that is formed when two parallel lines meet. The X-axis is the horizontal line, and the Y-axis is the vertical line. On the Cartesian plane, the coordinate point (x, y) indicates that the point is on the right of the origin if the sign of x is positive; otherwise, the point is on the left of the origin.
Given -210 degrees is in standard position,
-210° lies in the third quadrant,
which is 180° + 30° or π + 30°
the coordinate are x = cos(π + 30°)
and y = sin(π + 30°)
cos(π + Ф) = -cosФ and
sin(π + Ф) = -sinФ
x = cos(π + 30°) = -cos30° = -√3/2
y = sin(π + 30°) = -sin30° = -1/2
Hence the coordinates of points are (-√3/2, -1/2).

In a sample of people at the school dance 11 out of 15 were in favor of having the photo booth. If all 300 students were surveyed about the photo booth how many are likely to be in favor of the photo booth?
Answer:
If all the 300 students were surveyed, 220 would have been in favor of the photo booth.
Step-by-step explanation:
Sample size = 15
People out of 15 in favor of photo booth = 11
Percentage of people in favor of school dance = [tex]\frac{11}{15} \times 100\% = 73\frac{1}{3} \%[/tex]
We have to find if all 300 students are surveyed how many will be in favor of photo booth. Remember that, the sample data is the best estimator of the population data. So, the sample data of 15 students will be the best estimator for the entire population of 300 students.
Since, in the sample of 15 students, [tex]73\frac{1}{3} \%[/tex] were in favor of photo booth, we would expect that if all the 300 students were surveyed, the same percentage will be in favor of photo booth. So we need to calculate [tex]73\frac{1}{3} \%[/tex] of 300.
[tex]73\frac{1}{3} \% \text{ of 300}\\\\ = 73\frac{1}{3} \% \times 300\\\\ =\frac{220}{3} \% \times 300\\\\ =\frac{220}{300} \times 300\\\\ = 220[/tex]
This means if all the 300 students were surveyed, 220 would have been in favor of the photo booth as per the sample data.
Approximately 220 out of 300 students are likely to be in favor of the photo booth.
To determine how many of the 300 students are likely to be in favor of the photo booth, we can use the proportion given by the sample.
1. Calculate the proportion of students in favor from the sample:
Proportion = Number in favor / Total surveyed = 11 / 15
Proportion = 0.7333 (rounded to four decimal places)
2. Apply this proportion to the entire school population:
Expected number in favor = Proportion × Total school population
Expected number in favor = 0.7333 × 300
Expected number in favor ≈ 220
Therefore, out of 300 students, approximately 220 students are likely to be in favor of the photo booth.

A family went to a baseball game. They parked the car in a parking lot which charged $20. The cost per ticket was $27. Write an equation for the total cost of going to the baseball game, where y is the total cost and x is the total number of people. If the family spent $236, how many people went to the game?
Answer:
[tex]y=27x+20[/tex]
8 people went to the game.
Step-by-step explanation:
Let x represent number of tickets.
We have been given that the family parked the car in a parking lot which charged $20. The cost per ticket was $27.
The cost of x tickets would be [tex]27x[/tex].
The total cost of going to baseball game would be equal to cost x tickets plus parking cost that is [tex]27x+20[/tex].
Therefore, the equation [tex]y=27x+20[/tex] represents the total cost (y) of going to the baseball game.
To find the number of people who went to game, we will equate total cost with 236 as:
[tex]236=27x+20[/tex]
[tex]236-20=27x+20-20[/tex]
[tex]216=27x[/tex]
[tex]\frac{216}{27}=\frac{27x}{27}[/tex]
[tex]8=x[/tex]
Therefore, 8 people went to the game.
What is the length of CD? round to the nearest tenth
Answer: it is c. 10.7 cm
Rounded to the nearest tenth, the length of CD is approximately 5.8 cm.
To find the length of CD in a right triangle ABC where:
BA = 10 cm (the side adjacent to angle B)
angle B = 30 degrees
angle C = 90 degrees (a right angle)
angle D = 25 degrees
We can use the trigonometric ratio for tangent (tan) since we know the measure of angle B and the length of side BA. The tangent of an angle in a right triangle is the ratio of the length of the side opposite to the angle to the length of the side adjacent to the angle.
In this case, we want to find CD, which is the side opposite to angle B. So, we can use the following relationship:
tan(B) = CD / BA
First, find the tangent of angle B (30 degrees):
tan(30 degrees) ≈ 0.5774 (rounded to four decimal places)
Now, we can solve for CD:
CD = tan(B) * BA
CD ≈ 0.5774 * 10 cm
CD ≈ 5.774 cm
Rounded to the nearest tenth, the length of CD is approximately 5.8 cm.

Max wants to rent a bicycle. The cost to rent a bike is a $5 insurance fee plus $3 per hour. Max has at most $20 to spend. Write an inequality to represent this scenario. Give a value that satisfies the inequality.
The inequality that represents Max's situation with renting a bicycle is 5 + 3h <= 20. Max can rent the bicycle for up to 5 hours with his $20 budget, and renting for 4 hours would satisfy the inequality.
Explanation:The inequality to represent Max's situation with renting a bicycle, considering his budget constraints, would be:
5 + 3h \<= 20
Where h represents the number of hours Max can rent the bike. To solve for h, you subtract 5 from both sides of the inequality (which represents the fixed insurance fee) and then divide by 3 (the hourly rate for renting the bike):
3h \<= 15
h \<= 5
Thus, Max can rent the bicycle for up to 5 hours to stay within his budget of $20. An example value that satisfies this inequality is 4 hours, which would cost Max $5 for insurance plus $12 for the rental time, totaling $17.
Line segment QP is tangent to the circle. A circle is shown. Secant M P and tangent Q P intersect at point P outside of the circle. Secant M P intersects the circle at point N. The length of Q P is n, the length of N P is 11.5, and the length of M N is 24. What is the length of line segment QP? Round to the nearest unit. 13 units 17 units 18 units 20 units
Answer:
The length of line segment QP is 20 units ⇒ 4th answer
Step-by-step explanation:
If a secant and a tangent are drawn from a point outside the circle, then the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment
Look to the attached figure
∵ PQ is a tangent to the circle
∵ PM is a secant intersects the circle at points N and M
- That means the product of the lengths of PM and PN is
equal to the square of the length of PQ
∴ (PQ)² = (PN). (PM)
∵ The length of Q P is n units
∴ PQ = n
∵ The length of N P is 11.5 units
∴ NP 11.5
∵ The length of M N is 24 units
∴ MN = 24
- The length of the secant PM is the sum of the lengths of PN
and MN
∵ PM = PN+ NM
∴ PM = 11.5 + 24 = 35.5
Substitute the values of PQ, PN, and PM in the formula above
∵ n² = 11.5 × 35.5
∴ n² = 408.25
- Take √ for both sides
∴ n = 20.205197
- Round it to the nearest unit
∴ n = 20
∵ n is the length of PQ
∴ The length of line segment QP is 20 units
