Find car A and car B speed in km/h
Answer:
72 km/h and 48 km/hStep-by-step explanation:
Let the speed of the cars be x and y.
When moving in opposite directions, the speeds add up and when moving in the same direction the speeds subtracted.
Convert time from minutes to hour:
4 minutes = 4*1/60 hr = 1/15 hr20 minutes = 20*1/60 hr = 1/3 hrOpposite direction(x + y)*1/15 = 8x + y = 8*15x + y = 120Same direction(x - y)*1/3 = 8x - y = 8*3x - y = 24Add up the two equations and find the value of x:
x + y + x - y = 120 + 242x = 144x = 72Find y:

A tennis player hits the ball with an initial speed of 55 feet per second at an angle of 17°, from a height of 1.8 feet. How far away does the ball land in feet?
The range of the tennis player hitting the ball will be 172.43 meters away from the initial point.
What is the projectile motion?An item or particle that is thrown toward the planet's surface and moves somewhere along a curved route only under the influence of gravity is said to be experiencing projectile motion.
Let u be the initial speed and θ be the angle at which the ball hits. Then the range of the call is given as,
R = (u² sin 2θ) / g
Where 'g' is the acceleration due to gravity.
A tennis player strikes the ball at a height of 1.8 feet with an initial speed of 55 feet per second and an angle of 17°.
R = [55² x sin (2 x 17°) ] / 9.81
R = [3025 x sin 34° ] / 9.81
R = 172.43 meters

factor of 1 and point J as the center of dilation. How are the original figure and
its image related?
(I also need help placing JK’L’M’
The relationship between the figure JKLM and it's image, J'K'L'M' following a dilation by a scale factor of 1 is that JKLM and J'K'L'M' have the same dimensions, and location
J'K'L'M' should be placed at the same lol as JKLMWhat are scale factors?Scale factors are numbers that are used to multiply a quantity to scale it by a given rate.
Part A
In order to easily describe the relationship between the image J'K'L'M' and the original figure JKLM, the point J can be taken as the origin such that the image vertices are obtained by dilating the points on the original figure in their original direction relative to J using the specified scale factor.
The coordinates of the vertices of JKLM relative to J are;
J(0, 0), K(6, 0), L(6, -6), M(0, -6)
Distance of K from J = 6 - 0 = 6 units to the right of K
Therefore, using a scale factor of 1;
Distance of K' from J = 1 × 6 units = 6 units to the rightThe distances of the vertices of square J'K'L'M' from point J are the same and in the same direction as the distances of the vertices of square JKLM from point J.
JKLM and J'K'L'M' have the same dimensions following the dilation of JKLM by a scale factor of 1The vertices of J'K'L'M' using a scale factor of 1 are therefore located at the same coordinates as the vertices of square JKLM

What is the latest time she should leave home?
Give your answer as a time in the 24-hour clock.
Maria should leave home for the airport terminal at 14:30.
How to convert hour into minutes?Local time is the time of a location as determined by the apparent motion of the sun. The fixed time for locations on the same meridian set by law in a country is referred to as standard time. Changes in real time as longitude changes. The same applies to a specific country.We all know that one hour equals sixty minutes.
As a result, 6 hours = (6 × 60) minutes = 360 minutes.
For, the given question;
The time at which Maria need to be at airport terminal is 16:15.
Time taken for the driving is 1 1/3 = 4/3 hours.
convert this in minutes;
= 4×60/3
= 80 minutes.
Now, extra 25 minutes is requires to park.
Total time = 80 minutes + 25 minutes
Or we can write 60 minutes + 45 minutes.
Total time = 1 hour + 45 minutes.

B is the midpoint of AC and E is the midpoint of BD. If A(-9, -4), C(-1, 6), and E(-4, -3), find the coordinates or D
The coordinates of point D is (- 3, - 7).
How to determine the coordinates of a endpoint of a line segment divided by a midpoint
A midpoint is a point that partitions a line segment in two parts of equal length. First, we must find the coordinates of point B by using the midpoint formula:
B(x, y) = 0.5 · A(x, y) + 0.5 · C(x, y)
B(x, y) = 0.5 · (- 9, - 4) + 0.5 · (- 1, 6)
B(x, y) = (- 4.5, - 2) + (- 0.5, 3)
B(x, y) = (- 5, 1)
And the location of point D is found by using the midpoint formula again:
E(x, y) = 0.5 · B(x, y) + 0.5 · D(x, y)
(- 4, - 3) = 0.5 · (- 5, 1) + 0.5 · D(x, y)
(- 4, - 3) = (- 2.5, 0.5) + 0.5 · D(x, y)
(- 8, - 6) = (- 5, 1) + D(x, y)
D(x, y) = (- 8, - 6) - (- 5, 1)

There are 1680 ways to construct the octahedrons.
Here,
Eight congruent equilateral triangles, each of a different color, are used to construct a regular octahedron.
An octahedron has 8 equilateral triangles.
We have to find number of ways to construct the octahedron.
What is Regular octahedron?
An octahedron is a polyhedron with eight faces. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.
Now,
An octahedron has 8 equilateral triangles.
We have to fix 2 faces before applying the colors.
So, the first face that can be fixed for any of the 8 faces but each faces are similar.
Hence, there are 8/8 ways.
And, When we fix one face, three adjoining faces are similar.
So, we have 7 colors for the second face.
Hence, 7/3 ways
Now, we can place any color anywhere, it will be different arrangement.
So, 6! ways.
Hence, Total number of ways = (8/8) * (7/3) * 6! = 7 * 6 * 5 * 4 *2 = 1680
So, There are 1680 ways to construct the octahedrons.

Pls solve the question
The dimensions of the bulletin board is 2 ft and 9 ft.
Let the width of board = x
Then, the length of board = 7+x
Area of board = 18 ft²
Area of rectangle = L×W
so, (7+x) × x = 18 ft²
7x + x² = 18 ft²
7x + x² + 18 = 0
x² + 9x -2x -18 = 0
x(x+9) -2(x+9) = 0
(x+9) (x-2) = 0
x+9 =0, x -2 = 0
Dimension can not be in negative number, so
x = 2, Width = 2 ft
Length = 2+7 = 9 ft
Hence, the dimensions of board will be:
The width of board = 2 ft
And, the length of bard = 9 ft.
