The intersection of two planes contains at lease two points
What is intersection of two planes?
When two planes intersect, they form a line.
The vector equation for the line of intersection is given by
r = r₀ + tₓ
where r₀ is a point on the line
tₓ is the cross product of the normal vectors of the two planes.
The parametric equations for the line of intersection are given by
x = a , y = b and z = c
where a, b and c are the coefficients from the vector equation
r = a (i) + b (j) + c (k)
The line of intersection will be perpendicular to the normal of both the planes
The line of intersection lies on both the planes
Therefore , a line is observed at the intersection of two planes
Hence , the intersection of two planes always contains at least two points and it forms a line

A bird is flying 33 feet above sea level, a diver is 20 feet below sea level. What
is the distance between the bird and diver
Answer:
53 feet
Step-by-step explanation:
If the bird is flying 33 feet above sea level, and the diver is 20 feet below it would be 53 because you have to imagine right at sea level is a zero and 20 below with 33 above would equal 53
Answer:
53
Step-by-step explanation:
Distance is always positive, therefore the distance below and the distance above are added together: 33+20=53
A coach buys a uniform and a basketball for each of the 15 players on the team. Each basketball costs $9. The coach spends a total of $420 for uniforms and basketballs. What is the cost of one uniform? Use a strategy that makes sense to you. Show your thinking!
Answer:
$19
Step-by-step explanation:
Since there are 15 players and he bought a basketball for each of them, he bought 15 basketballs in total.
The price of a basketball costs $9.
The total price of all 15 basketballs = $9 * 15 = $135.
He spent $420 on uniforms and basketballs, and he spent $135 on basketballs.
Thus, he spent $420 - $135 = $285 on uniforms.
As he bought a uniform for each of the 15 players, he bought 15 uniforms in total.
The price of 15 uniforms is $285.
The price of 1 uniform is $285 ÷ 15 = $19.
Answer:
$19.
Step-by-step explanation:
Let x be the cost of a uniform:
Then we have 15 (x + 9) = 420.
We can divide both side by 15, getting x + 9 = 28.
Then, we can subtract both sides by 9, getting x = 28 - 9 = 19.

Nancy bought 5 1/2 pounds of apples and oranges. If she bought 1 2/3 pounds of apples, which of the following equations could be used to find the amount of oranges she bought?
Answer:
1 2/3a+o=5 1/2
Step-by-step explanation:
1 2/3 pounds of apples plus the weight of oranges is equal to 5 1/2 pounds. The weight of the oranges can be found by subtracting the weight of apples from the total weight, which is 3 5/6 pounds.
The equation which represents the number of oranges and apples is 1²/₃a+o=5¹/₂.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Nancy bought 5¹/₂ pounds of apples and oranges. If she bought 1²/₃ pounds of apples.
The equation will be written as,
1²/₃a+o=5¹/₂.
1²/₃ pounds of apples plus the weight of oranges is equal to 5¹/₂ pounds. The weight of the oranges can be found by subtracting the weight of the apples from the total weight, which is 3⁵/₆ pounds.
Therefore, the equation which represents the number of oranges and apples is 1²/₃a+o=5¹/₂.

Answer:
G(18,-9)
Step-by-step explanation:
The coordinates of the midpoint of GH are M (8,0) and the coordinates of one endpoint are H(-2, 9). We need to find the coordinates of G. Let G is (x,y).It can be done using mid point formula i.e. [tex](\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
So,

X would have to equal 6 or greater as if x was 5
5+3 is the same as 8
Answer:
I would say no.
Step-by-step explanation:
If x would be 5, then the greater than sign would turn into a equal sign. This is because 5 + 3 = 8. So this (x + 3 > 8) would turn into this (x [or 5] = 8).

Jennifer and Kamlee are walking to school. After 20 minutes, Jennifer has walked 4/5 miles. After 25 minutes, Kamlee has walked 5/6 miles. Find their speed in miles per hour
Answer:
Jennifer's speed is 2.4 miles/hour
Kamlee's speed is 2 miles/hour
Step-by-step explanation:
To find their speed,
Speed can be determined from the formula below,
[tex]Speed = \frac{Distance}{Time}[/tex]
Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)
For Jennifer,
Distance = 4/5 miles
Time = 20 mins (Convert to hour)
∴Time = (20/60) hour = 1/3 hour
Hence,
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{4/5 miles}{1/3hour}[/tex]
[tex]Speed = \frac{4}{5} \times \frac{3}{1}[/tex]
[tex]Speed = \frac{12}{5}[/tex]
[tex]Speed = 2.4 miles/hour[/tex]
Hence, Jennifer's speed is 2.4 miles/hour
For Kamlee,
Distance = 5/6 miles
Time = 25 minutes (Convert to hour)
Time = (25/60) hour = 5/12 hour
Hence,
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{5/6miles}{5/12 hour}[/tex]
[tex]Speed = \frac{5}{6} \times \frac{12}{5}[/tex]
[tex]Speed = 2 miles/hour[/tex]
Hence, Kamlee's speed is 2 miles/hour
