Answer:
Proportion states that the two ratios or fractions are equal
Given the statement:
The scale on map is 2 cm =25 miles.
Dave measured the distance to the next town at 5 cm.
We have to find the what miles away is the next town.
Let x be the distance in miles away is the next town.
By definition of proportion:
By cross multiply we get;
Simplify:
Divide both sides by 2 we get;
x = 6.25 miles
Therefore, 6.25 miles away is the next town.

Answer:
1. 6 in.
Step by step explanation:
Let the width of our rectangle be x inches.
We have been given that the length of our rectangle is three times the width, therefore, length of our triangle will be 3x inches.
We are told that area of the rectangle is 108 square inches.
Since we know that
Let us substitute our given information in area formula.
Upon multiplying 3x by x we will get,
Let us divide both side of our equation by 3.
Upon taking square root of both sides of our equation we will get,
Since width cannot be negative, therefore, width of our rectangle will be 6 inches and 1st option is the correct choice.
Answer:
No
Step-by-step explanation:
y = 2x -1
Substitute the point into the equation
4 = 2(3) -1
4 = 6-1
4 =5
This is not a true statement so the point is not on the line
The planar
density for the (100) plane is
PD100 (Ni)=1/(4R²)=1/(4*0.125²)=16.00 nm-2 = 1.6 x10^19 m-2
the answer is 1.6 x10^19 m-2
