Hence, the number is -125.
Using algebraic expression, the number is calculated as: -125.
What is an Algebraic Expression?An algebraic expression involves using numbers and variables to make statements.
Let the unknown number be represented as x. Therefore:
Twice the number is 2x
2x is 500 more than 6x is 2x = 6x + 500
Solve the algebraic equation to find the number (x):
2x = 6x + 500
2x - 6x = 500
-4x = 500
x = -500/4
x = -125
Thus, using algebraic expression, the number is calculated as: -125.

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.

Hi, to calculate area of a shape; you have to do length multiplied by width. However this formula may vary when calculating different shapes like triangles etc.
i really need help please give a simple and plain answer like the exaple in the photo
Answer:
Hi! To find x (the missing angles of the triangles), remember that the angles in a triangle add up to 180 degrees. This means that for each triangle, you can add the two angles given, then subtract that number from 180 to find x. I'll use Triangle 1 as an example:
81 + 84 = 165
180 - 165 = 15
So for Triangle 1, x is equal to 15.
To classify each triangle by angles, remember that an acute triangle has three angles that each measure less than 90 degrees, a right triangle is a triangle with one 90 degree angle, and an obtuse triangle is a triangle with one angle that is greater than 90 degrees. To classify each triangle by sides, remember that scalene triangles have three sides of unequal length, isosceles triangles have two sides of equal length, and equilateral triangles have three sides of equal length.
Keeping all this in mind, here are your answers:
Triangle 1 - 15 acute scalene
Triangle 2 - 120 obtuse scalene
Triangle 3 - 41 right scalene
Triangle 4 - 104 obtuse isosceles
Triangle 5 - 25 right scalene
Triangle 6 - 64 acute scalene
Triangle 7 - 72 acute scalene
Triangle 8 - 32 obtuse scalene
Triangle 9 - 40 right scalene

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

Step-by-step explanation:
The given situation can be illustrated as a picture which I have attached to the answer for better understanding.
As you can notice, the situation can be modeled as a right triangle.
Use the Pythagorean theorem to find the value of leg h, as follow:
[tex]h=\sqrt[]{(7.5m)^{2} - (6.2m)^{2}} \\h=\sqrt{56.25m^{2} - 38.44m^{2}}\\h=\sqrt{17.81m^{2} } \\h= 4.2 m[/tex]
Rounding of the answer : 4 meters
Hence, the height of the tree is approximately 4m.

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

Anita went to lunch with some friends and paid $260 for the final bill, including tip. If they left a 16% tip, what was the bill before the tip?
Answer:
The bill was $218.40 before the tip
Step-by-step explanation:
The $260 is the amount with the tip, if 16% of the bill was the tip, we need to find what 100% - 16% of the bill is.
[] First, 100% - 16% is 84%
-> We need to find 84% of $260
[] Next, 84% can become 0.84
-> 260 * 0.84 = $218.40
