Answer:
18,75
Step-by-step explanation:
A square has 4 sides, and each one of them are equal, so 75 divided by 4 its equal to 18,75
Answer:11 miles
Step-by-step explanation:
Answer:
The length of the rectangle is 11 inch and its width is 8 inch.
Step-by-step explanation:
Given:
Rectangle 
and rectangle 
.
Let the width of the rectangle be 'x' inch.
Its length = '(x+3)' inch
Area of the rectangle = 
⇒
= 
Now for rectangle its width is decreased by 1 inch and length is doubled,the area 
will increased by 66 sq-inch.
So,
According to the question.
⇒ Area of rectangle with width '(x-1)' and length '2(x+3)'='(2x+6)' .
⇒ 
Plugging the values of 
in terms of .
⇒ 
Plugging = into the equation.
⇒ 
⇒ 
⇒ 
⇒ 
Now using quadratic formula we can find the value of 'x'.
Quadratic formula, (x)= 
x= -9 and x= 8
Discarding the negative value.
Our width = 'x' = 8 inches.
So the length of the rectangle = 11 inches and width of the rectangle = 8 inches.
Answer:
r = 13
Step-by-step explanation:
these angles are vertical and are congruent
8r + 6 = 9r - 7
6 = r - 7
13 = r
It really depends on how precise you're going to get.
You could get away with only two parts, but to be really precise, you should probably divide it into twelve (12) parts, because 5/12 means five out of twelve parts, so its would be right on the fifth subdividing marker line.
