A=pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
A≈353.25 ft^2
If you would illustrate the problem, you will be able to
formulate a triangle with the measurement of the hypotenuse (distance between
the two shops) to be missing. Using the Pythagorean Theorem, the formula to
compute for the hypotenuse is:
c = √a^2 + b^2
c = √(20)^2 + (13.5)^2
c = √400 + 182.25
c = √582.25
c = 24.13 km
Therefore, the distance between the two shops
is approximately 24.13 km.
Answer:
9³
Step-by-step explanation:
We need to find the value of 
.
We know that,
Here, a = 5 and b = 2.
So,
So, the answer to the given expression is 9³.
Answer:
The coordinates of M are (2,-8)
Step-by-step explanation:
The coordinates of the point that divides the line segment joining
to 
in the ratio m:n is given by:
If A is at (-4,-2) and B is at (4. -10) and the ratio is 3:1.
Then
The coordinates of M are (2,-8)
Answer:
x = - 8 , x = 2
Step-by-step explanation:
the absolute value function always gives a positive result, however, the expression inside can be positive or negative, , that is
x + 3 = 5 ( subtract 2 from both sides )
x = 2
or
-(3 + x) = 5
- 3 - x = 5 ( add 3 to both sides )
- x = 8 ( multiply both sides by - 1 )
x = - 8
