It took a plane 2 hours to fly from Dallas to New York with the headwind and 1.5 hours to return with the tailwind. If the speed of the wind was 30 mph, how far apart are the two cities?
Answer:
The distance between the two cities is 360 miles.
Step-by-step explanation:
Let a equal the airspeed of the plane in still air; and d be the distance between the two cities. Then:
d/a+30=1.5
d=1.5a+45
and
d/a-30=2
d=2a-60
So
2a-60=1.5a+45
.5a=105
a=210
d/210-30=2
d=360
The distance between the two cities is 360 miles.

Answer:
Draw a rectangle.. write 13 on the two longer sides of the rectangle then write 7 on the other two shorter ones. Then add them all up and there you go your answer!
Our equation would be 13 + 13 + 7 + 7 = 40 inches
Step-by-step explanation:
The values of r for which the shaded region will be greater than or equal to 12 square units is;
r ≥ 8
We can see a rectangle and a triangle in the given image.
With the triangle being the unshaded portion of the rectangle.
Thus;
Area of shaded portion = Area of rectangle - area of rectangle.
We know that formula for area of rectangle is;
A_r = length × width
Thus; A_r = 3 × r
A_r = 3r
Area of a triangle is;
A_t = ½ × base × height
A_t = ½ × r × 3
A_t = ½(3r)
Thus;
Area of shaded portion = 3r - ½(3r)
Area of unshaded portion = 1.5r
We are told that the area of the unshaded region should be greater than or equal to 12. Thus;
1.5r ≥ 12
r ≥ 12/1.5
r ≥ 8

On the dashboard of Josh's car, there is a clock and an odometer. The odometer tells how many total miles the car has been driven. Josh glances at his car's dashboard (A), and then looks back a few minutes later (B). (Pls I need help.)
a) Between the two times, Time A and Time B, 12 minutes passed (total time).
b) During this time, Josh drove his car for 10.8 miles (total distance).
c) This means that Josh was driving at an average rate (speed) of 0.9 miles per minute.
What is the average rate?The average driving rate refers to the speed at which Josh was driving his car.
The average rate is the quotient between the total distance covered and the total time taken to cover the distance.
The distance, time, and speed formula are Distance = Time x Speed.
Therefore, Speed = Distance/Time.
Reading on odometer at 9:53 = 52,604.1
Reading on odometer at 10:05 = 52.614.9
Distance covered = 10.8 miles (52.614.9 - 52.604.1)
Difference in time = 12 minutes (10:05 - 9:53)
Average speed = 0.9 miles per minute (10.8/12)

Graph the line given by the equation.
2y = -3x
Answer:
1. Slope = -3.000/2.000 = -1.500
2. x-intercept = 0/3 = 0.00000
3. y-intercept = 0/2 = 0.00000
Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Equation of a Straight Line
1.1 Solve 2y+3x = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2y+3x = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 0/2 so this line "cuts" the y axis at y= 0.00000
y-intercept = 0/2 = 0.00000
Calculate the X-Intercept :
When y = 0 the value of x is 0/3 Our line therefore "cuts" the x axis at x= 0.00000
x-intercept = 0/3 = 0.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -0.000 and for x=2.000, the value of y is -3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -3.000 - -0.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -3.000/2.000 = -1.500
Geometric figure: Straight Line
Slope = -3.000/2.000 = -1.500
x-intercept = 0/3 = 0.00000
y-intercept = 0/2 = 0.00000
