A scale drawing of the Mojave desert has an area of 10 square inches.
What is the scale of the map?
I need someone to explain me how to get the answer of this problem. Btw I am in seventh grade
Based on the area of the Mojave desert and the area of the scale drawing, the scale of the map is 1 square inches : 2,500 square miles.
How to find the scale of a map?The scale of a map is used to find out how the distance on the map relates to the distance on the ground. It is usually shown as a ratio.
The fact that the area of the Mojave desert is 25,000 square miles but only 10 square inches on the scale drawing means that every 10 square inches on the map is equal to 25,000 actual square miles.
The scale is:
10 square inches : 25,000 square miles
In its simplest form, this is:
10 / 10 square inches : 25,000 / 10 square miles
1 square inch : 2,500 square miles

question 4 (10 points)
The slope of the table is 3.
In this question, we have been given a table.
We need to find the slope of the table.
For aby two points (x1, y1) and (x2, y2), we use the formula of slope,
m = (y2 - y1) / (x2 - x1)
m1 = (15 - 30) / (-5 - 0)
m1 = (-15) / (-5)
m1 = 3
For a pair of points (-5, 15) and (10, 60)
m2 = (60 - 15) / (10 + 5)
m2 = 45 / 15
m2 = 3
For a pair of points (10, 60) and (5, 45)
m3 = (45 - 60) / (5 - 10)
m3 = -15 / -5
m3 = 3
Therefore, the slope of the table is 3.

Consider triangle G,
The height of the triangle is 4.
The base of the triangle is 3.
The hypotenuse of the triangle is 5.
Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.
Therefore,
Area of ΔF = 4 × Area of ΔG
(b) Triangle G and Triangle B
Consider triangle G,
The area of the triangle is:
Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.
Consider triangle B,
The height of the triangle is 2.
The base of the triangle is 3/2.
The hypotenuse of the triangle is 5/2.
Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.
Now, 4 × 3/2 = 6
Therefore,
Area of ΔG = 4 × Area of ΔB
Area of ΔB = 1/4 × Area of ΔG
(c) Triangle B and Triangle F
Consider triangle B,
Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.
Consider triangle F,
Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.
Now, 16 × 3/2 = 24
Therefore,
Area of ΔF = 16 × Area of ΔB
(d) Triangle F and Triangle H
Consider triangle F,
Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.
Consider triangle H,
The height of the triangle is 8/3.
The base of the triangle is 2.
The hypotenuse of the triangle is 10/3.
Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.
Now, 9 × 8/3 = 24
Therefore,
Area of ΔF = 9 × Area of ΔH
Area of ΔH = 1/9 × Area of ΔF
(e) Triangle G and Triangle H
Consider triangle G,
Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units
Consider triangle H,
Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.

Answer:
Step-by-step explanation:
385 dollars is cut into three parts, one part is 5 times bigger, the other is $35 more how much money is in each part
so the first part is p
the second part is 5p
the third part is p+35
all together, you have 7p + 35 = 385
so 7p = 350, so p = 50.
so the first part is 50, the second part is 250, and the third part is 85. together they make 385!

The required equation is x+4y-9 = 0.
What is an equation?
Algebra is concerned with two types of equations: polynomial equations and the particular case of linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial, while linear equations have the form ax + b = 0, where a and b are parameters, when there is only one variable. To solve equations from either family, algorithmic or geometric approaches derived from linear algebra or mathematical analysis are used. Algebra also investigates Diophantine equations with integer coefficients and solutions. The approaches employed are unique and derive from number theory. In general, these equations are complex; one frequently searches just for the existence or lack of a solution, and, if they exist, the number of solutions.
The equation is formed below
(y-2) = {(1-2)/(3+1)} (x+1)
or, y-2 = - 1/4 (x+1)
or, 4(y-2) = -1(x+1)
or, 4y - 8 = 1 - x
or, x+4y-9 = 0
Hence, the required equation is x+4y-9 = 0.

The value of y in the expression -5(2x - 5) = 6x + 3 is 22/16
According to the given question
We have an equation in one variable
⇒ -5(2x - 5) = 6x + 3
For finding the value of x solve the above equation by adding and subtracting the like terms.
So, -5(2x - 5) = 6x + 3
⇒ -5 x 2x + 5 x 5 = 6x + 3
⇒ -10x + 25 = 6x + 3
⇒ 25 - 3 = 6x + 10x
⇒ 22 = 16x
⇒ x = 22/16

What is a Triangle?Having three straight sides and three angles, a triangle is a flat figure.In Euclidean space, the total of a triangle's internal angles is always 180 degrees. The parallel postulate of Euclid is comparable to this fact. By using the measurements of the first two angles, it is possible to calculate the size of the third angle in any triangle. An angle that is a linear pair (and thus supplementary) to an interior angle is the outside angle of a triangle. The exterior angle theorem states that the measures of two inner angles that are not contiguous to each other add up to the measure of an exterior angle of a triangle. Any triangle's three outside angles, one for each vertex, add up to a total of 360 degrees.To learn more about Triangles, refer to:
