A traffic helicopter flew directly from Point A to Point B in 8 minutes. Did the helicopter travel faster or slower than the driver? Explain or show your reasoning.
Answers
The time it takes the driver to travel from Point A to Point B is 8 minutes, the same as the helicopter but through a more longer path, such that, we have;
The helicopter travels slower than the driverHow can the speed of the helicopter and the car be compared?Based on a similar question, the first part required to determine if a driver that drives from Point A to Point B in 8 minutes obeyed the speed limit of 55 miles per hour.
The path of the driver consists of a short path, a bend changing the direction, then a long straight path.
The path of the helicopter is directly from Point A to Point B.
Therefore;
The length of the path of the driver, d1, is longer than that the helicopter, d2, which gives;
d1 > d2
From kinematics, we have;
[tex]Speed = \frac{Distance}{Time} [/tex]
The time taken by the helicopter and the and the driver are equal to 8 minutes, therefore;
[tex] Speed \: of \: the\: driver = \frac{d_1}{8} [/tex]
[tex] Speed \: of \: the \: helicopter = \frac{d_2}{8} [/tex]
[tex] d_1 > d_2 [/tex]
According to the division property of equality, we have;
[tex] \frac{d_1}{8} > \frac{d_2}{8} [/tex]
[tex] \frac{d_2}{8} < \frac{d_1}{8} [/tex]
Therefore;
The speed of the helicopter is lesser than the speed of the driver, which gives;

The volume of dry goods, like apples or peaches, can be measured usings bushels, pecks, and quarts. A bushel contains 4 pecks, and a peck contains 8 quarts.
What is the relationship between number of bushels, b, and the number of quarts, q? If you get stuck, try creating a table.
Answers
The relationship between the number of bushels and the number of quarts is b = 32q.
What is the relationship?The mathematical operation that would be used to determine the required value is multiplication. Multiplication is the process of determining the product of a number. The sign used to represent multiplication is x.
The equation that represents the relationship between bushel and pecks is: b = 4p
The equation that represents the relationship between a peck and quarts is: p = 8q
In order to determine the relationship between bushels and quarts, substitute for p in the first equation
b = 4(8q)

nikki and kelly can create math problems for a particular course in 20 hours. alone, nikki can do write all of the problems 4 hours faster than kelly could if she were to work alone. how long would it take each person to write the problems if they worked alone?
Answers
Nikki alone can do work to write the problem in 43 hours, and Kelly can work in 39 hours.
What are work and time?
Work is the energy expended to complete a task or produce a deliverable. It takes a specific amount of time (T) to finish a particular task (W). The rate of work is the number of units of work completed per unit of time (R). Therefore, Work (W) = Rate (R) Time (T), and Work = Force Distance can be used to determine Work.The joule (J), sometimes known as the Newton meter (N m), is the SI unit for work. When an object is moved across a distance of 1 m with 1 N of force, one joule is equal to the amount of work that is accomplished.
Work and time are proportionate to one another. Because of this, more work can be done with more time, and vice versa.
Nikki can do the part of this problem in 1 hour = 1/x
And, Kelly can do the part of this work in 1 hour = 1/(x - 4)
So, Nikki and Kelly both can do this work in 1 hour = (1/x) + [1/(x - 4)] = 120
= 40x - 80
= x² - 4x
= x = 43, 2
Hence,
Nikki alone can do work to write the problem in 43 hours, and Kelly can work in 39 hours.

Step-by-step explanation:
You can walk 4/5 of a mile in 1/4 of an hour (15 minutes). How far can you walk in an hour?
If you can walk 4/5 of a mile in 1/4 of an hour the equation would be:
4/5x = 1/4
multiply both sides by 4:
4(4/5x) = 4(1/4)

The measure of angle A and angle B are 31° and 59° respectively.
What are complementary angles?Complementary angles that sum up to 90 degrees.
Given the angles as;
angle A = 3x+7angle B =6x+11We have that;
Angle A + Angle B= 90
Substitute the values
3x + 7 + 6x + 11 = 90

Find the slope of the following lines
Explain how you got the answer
Answers
[tex]-\displaystyle\frac{4}{3}[/tex]
Step-by-step explanation:Slope describes the change in y divided by the change in x.
Solving Using Slope Formula
One way to find slope when you are given 2 points is the slope formula.
Slope = [tex]\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex]To solve, plug in the x and y-values and simplify. For this question, let (-2, 3) represent the (x₂, y₂) and (1, -1) represent (x₁, y₁).
[tex]\displaystyle\frac{3-(-1)}{-2-1}=-\frac{4}{3}[/tex]This shows that the slope of this line is -4/3.
Solving Through Counting
When given the graph of a function, you can also count out the slope. Starting from the left point, count the change in y-values and the change in x-values. Remember, when the y-values decrease, the change should be negative. The y-value changes by -4 and the x-value changes by +3.
Since the slope is change in y over change in x, the slope is -4/3.
