An airplane climbs at an angle of 12° with the ground. Find the horizontal distance it has traveled once it has reached an altitude of 500 feet. using cos
Answer:
2352.32
Step-by-step explanation:
Sin 12 = 500/H
H = 2404.86717
Cos(12) = A/2404.86717
A = 2352.32
The horizontal distance it has traveled once it has reached an altitude of 500 feet is approximately 2352 feet.
The situation forms a right angle triangle
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
The altitude of the plane is the opposite side.
The horizontal distance it travelled is the adjacent side of the triangle formed.
Therefore,
tan 12 = opposite / adjacent
tan 12 = 500 / a
a = 500 / tan 12
a = 500 / 0.2125565616
a = 2352.31573723
a = 2352 feet

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 that are different in colour?
Answer:
15/28Step-by-step explanation:
There are 3 blue, 5 red and the total of 8 marbles.
Two different colored marbles are:
blue, then red or red, then blueFind the probability of each case:
P(b, r) = 3/8*5/7 = 15/56P(r, b) = 5/8*3/7 = 15/56Required probability is:
P(different color) = 15/56*2 = 15/28Answer:
15/28 is the probability of getting 2 that are different in colour.
Step-by-step explanation:
3 blue and 5 red marblesHe is going to pick any marble, in second try, it must be a different colour marble.
total marble: 3 + 5 = 8 marbles
For blue marble:
In first try for blue marble: 3/8
total marble will decrease by 1, 7 marbles.second try for red marble: 5/7
probability then: 5/7 * 3/8 = 15/56 is the probability for blue marble.
For red marble:
In first try for red marble: 5/8
total marble will decrease by 1, 7 marbles.second try for blue marble: 3/7
probability then: 5/8 * 3/7 = 15/56

7) Solve the equation for the variable given.
Solve for x.
m=2x+b/3
Answer:
x= m/2 - b/6
(its a lot of work...)
Step-by-step explanation:
1. Subtract 2x from both sides
-2x=2x+b/3-2x
2. Simplify
-2x=b/3
3. Factor
x(m-2)=b/3
4. divide both sides by m-2; m≠2
x(m-2)/m-2=b/3/m-2 m≠2
5. Simplify again...
x=b/3(m-2); m≠2

Answer:
x < -2
Step-by-step explanation:
Okay, so the dot is at -2 and is facing left. Left means less than, so, we know x is less than -2.
But we don't know if it's equal to or less than or just less than.
The dot is hollow, which in graphing means that it is not equal to or less than.

If 1 inch represents 68 miles on a map, then how many inches will represent 8600 miles
Answer:
126.470588235
Step-by-step explanation:
I like to set these up like how I set up my radian conversions so what I do is I have one unit on top of a fraction and another on the bottom so it would look like this 1/68 = x/8600 this equation will let us solve for x which would be our inches to get 8600 so we just times 1/68 by 8600 and get 126.470588235 and just to check 126.470588235 * 68 = 8600

What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of a square is the square of the length of the side of the square. Therefore, the area of the square and the length of the side of the square can be written as,

The length of a
rectangle is represented by
4a + 3b, and its width is
represented by 7a – 2b. Write
a polynomial for the perimeter
of the rectangle.
Solution:
Given:
Length of rectangle = 4a + 3bWidth of rectangle = 7a - 2bPerimeter of rectangle = 2W + 2LLet's simplify the perimeter of the rectangle by using the expression for the perimeter.
=> 2W + 2L=> 2(7a - 2b) + 2(4a + 3b)=> 14a - 4b + 8a + 6b=> 22a + 2bHence, the polynomial that represents the perimeter of the rectangle is 22a + 2b.

What is an equation of the line that passes through the point (–2, 5) and is perpendicular to the line y=12x + 5 ?
What is an equation of the line that passes through the point (–2, 5) and is perpendicular to the line y=12x + 5 ?
y = 12x + 5
- 12x + y = 5
gradient 1 = -a/b
= -(-12) / 1
= 12/1
= 12
gradient 2 × 12 = -1
Gradient 2 = -1/12
y - y1 = m (x - x1)
y - 5 = -1/12 ( x - (-2))
multiply all, by 12
12y - 60 = - 1 (x + 2 )
12y - 60 = -x - 2
x + 12y = - 2 + 60
x + 12y = 58
Wangari plants trees at a constant rate of 12 trees every 3 hours.
Write an equation that relates p, the number of trees Wangari plants, and h, the time she spends planting them in hours.
Answer:
[tex]p = 4h[/tex]
Step-by-step explanation:
The equation of straight line is given by:
[tex]y = mx[/tex]
where, m is the slope or rate of the line.
As per the statement:
Wangari plants 12 trees every 3 hours.
By definition of unit rate:
Unit rate per hour [tex]= \frac{12}{3} = 4[/tex] trees
⇒[tex]m = 4[/tex]
We have to find an equation that relates the number of trees Wangari plants (p) and the time she spends planting them (h) in hours.
then;
[tex]p=4h[/tex]
where, p represents the plant trees and the time she spends planting them in h hours
Therefore, [tex]p=4h[/tex] an equation that relates the number of trees Wangari plants (p) and the time she spends planting them (h) in hours.
